• Dell inspiron 7520, how to get a resolution of 2560 x 1440 on external monitor?

  Hi all

  I have a fairly new Dell inspiron 7520, AMD Radeon HD M 7730, Intenl HD Graphics 4000. I just bought a 27 "monitor that I wanted to work on the resolution of 2560 x 1440. My monitor has only DP, HDMI and DVI-ports and my laptop has VGA and HDMI ports. I tried the HDMI, but it looks like its 2560 x 1440, but 1900 x 1080 cant handle. It's really frustrating for me because I bought the monitor with 2560 x 1440. I tried it before on other monitors by using the VGA and I managed to run 2560 x 1440. What is the solution here?

  -Can I get a VGA-DVI/DP cabel? or adapter?

  -There's another device that I can connect to?

  -I have to take my laptop and get the upgrade? If Yes, where can I do this in China? So many false places here and I wanted to take the official Dell store - but can't find in Shanghai.

  Thanks, 1 million - that's very frustrating. Can't believe my fairly new dell laptop can't handle 2560 x 1440. My 4 roommates macbook air still for this. Another problem, I love my computer dell laptop.

  Thank you.

  I missed the part, no DVI.  Use the VGA/DVI, you need a set-top box power - VGA is analog, digital DVI.  You may not use a single cable.  Unfortunately, I do not think that these will run a very high resolution.  They are all limited to the 1920 resolution.

  It is a system relatively low-end and low-end systems have their limits - the resolution that you want to run is a high-end - need you a notebook of top line (with a displayport) run the desired resolution.

• Dell Inspiron 7520 fuzzy applications after windows 8.1 upgrade

  Hello

  I have recently installed windows 8.1 on my Dell Inspiron 7520.

  After the upgrade, the switchable GPU do not work, and many applications have a different (and fuzzy) resolution compared to the rest of the screen. All Dell video drivers (even drivers for windows 8.1) do not resolve the problem.

  I solved the switchable GPU problem, install the latest drivers video, taken directly from sites Web Intel and AMD:

  -for the Intel HD 4000: pilot 10.18.10.3277, 8 - 19.2013

  -for the AMD Radeon 7730: pilot 14.501.1003.0, 20/11/2014.

  This is the only combination of drivers that works (I tried many...) but the fuzzy applications issue is still unresolved. Look at the picture in the link below (the resolution of the screen is correct, while the words in the window are blurred).

  

  Does anyone have a solution? Thank you.

• Poor performance of Firefox after you apply the latest Microsoft Updates (Win 7 x 64); all solutions?

  Recently, I updated to Firefox 27 and noticed really horrible performance (Manager tasks indicates FF connecting a carrot, frequent "Firefox is not responding messages", even strikes in late development in the URL bar). It's on an Ideapad s205 (AMD E450 APU, Win 7 x 64, 8 GB RAM, SSD) who has always had pretty decent web browsing performance for a low end machine.

  At first, I blamed FF because poor performance coincided with the update to version 27, but now I think that the first cause to be a recent Microsoft Update. The reason is that my wife has a laptop with a same low-end APU (APU C60, hard drive 5400 RPM, 4 GB of RAM, Win 7 x 64), and she was getting much better performance with FF27 until I applied a backlog of some 90 + updates. Now she suffers from the same poor performance I am and she is pretty p * ssed at home.

  Interestingly, I have two WIn 7 x 64 Intel computers to office who have 27 FF and are fully patched, and performance are very good. Maybe this problem is specific to AMD APU.

  Any thoughts? I tried to turn off the backend Azure with some comments in this forum, but makes little or no difference.

  Thank you!

  Success! 32 FF seems to have solved my problems of performance. Thank you!

• HP Mini 110-3530NR extremely poor performance on the Internet

  My HP Mini 110-3530NR Netbook has very poor performance on the Internet.  I use Windows 7 Starter.

  Say hello to new coppens1.  I apologize for the delay in my responses.  I have not received the normal e-mail notifications.

  1. Click Start, type "msconfig" and press ENTER.
  2. Go to the Services tab and search for "HP Software Framework".  This should load with Windows for a lot of the HP software to work properly.
  3. Then go to the Startup tab and make sure that anything it either by "Synaptic" is loaded with Windows.
  4. Save your changes and exit msconfig.
  5. Then go to your touchpad settings and, even once, make sure that the settings are correct.

• Problems of internet connectivity with Dell Inspiron 7520 (1703 of Dell Wireless 802.11b/g/n 2.4 ghz)

  Hello

  I bought a Dell Inspiron 7520 for a week now, and I had a strange problem with internet connectivity since then. First, wifi takes a lot of time to connect. After, I'm online, every 10 minutes my network access stops working completely. But if I click on the network icon in the toolbar, it starts working again, but it stops in the next 10 minutes, once again, and so on. If I try to fix connectivity problems, he always find and solve some in the network card or wireless, but then point again, after 10 minutes, or so, it happens again.

  My network card is a Wireless Dell 1703 802.11b/g/n 2.4 ghz and I tried to update and to re - download the firmware, but nothing seems to fix.

  What should I do to fix this?

  Hello friends. Recently I came across the same problem identified by many with a Dell Inspiron 15R laptop 7520 with the Dell Wireless 1703 (Atheros chipset). After losing an entire afternoon and looking at forums and their complaints, I think that I found the solution to the problem (at least, here is running).

  The laptop is connected to a router TP-Link TL-WR740N. The router is configured to run with a frequency of 20 or 40 MHz, making the switch automatically in the factory. The mobile card wireless driver is configured to work only with 20 MHz at the factory. But can be configured to work with two frequencies is adapted automatically. To do this, change the configuration (in Windows 7):

  Start > Control Panel > Device Manager > network adapters > Dell Wireless 1703 802.11b/g/n (2,4 GHz) > click the Advanced tab > select 802.11n bandwidth. Change the value of Auto 20 MHz / 40 MHz.

  Press OK and wait for to reconnect you.

  I hope this helps.

• How to do a clean install of Windows 7 on Dell Inspiron 7520 (aka Inspiron 15R Special Edition)

  The operating system that are preloaded on my Dell Inspiron 7520 (a.ka. Inspiron 15R Special Edition) is Microsoft Windows 7 Home Premium. I have a retail version of Microsoft Windows 7 Ultimate and want to do a clean install on my laptop.

  My laptop was able to boot from the retail disk.

  After clicking on 'Install now' and accepted the terms and conditions of Microsoft Windows 7 Ultimate, I checked the configuration box "Custom (advanced option" in which a new copy of Windows would be installed. The next screen that displayed contained the following bizzare message: no hard drive found. "Click on load a driver to provide a driver for installing mass storage.

  Could someone tell me where and how to find the mass storage driver?

  I am also having exactly the same problem:

  After getting BSOD (indicating iaStor.sys) every 20 minutes or so I decided to format the laptop and install my copy of opportunity of Win7 Pro SP1. I jumped in the Win7 DVD and I saw that the couldn t of windows setup find any HARD drive to install to.

  I downloaded the drivers from Intel (f6flpy - x 64) and them burned on a CD. It took me a few tries (I kept getting error messages), but the computer finally accepted Intel Mobile Express Chipset SATA RAID Controller drivers.

  Finally, I could see the readers. So I deleted the partition of 1 TB, created two new partitions (~ 100 GB and GB 890) and clicked on 'format' on two of them.

  But when I tried to select ONE of them as the destination for Windows drive, I received the following message:

  "Windows cannot be installed to Disk 0 Partition 3. Details: Windows cannot install to the selected location. "Error 0 x 80300001.

  So now when I turn on my laptop (since there is no operating system or anything), I get a black screen with the following message:

  Windows Boot Manager «»

  Windows could not start; A recent hardware or software change might be the cause. To solve the problem:

  blablabla (nothing really useful)

  Status: 0xc0000034

  Info: an unexpected error occurred. »

  Before I read this thread I also tried to change the SATA settings to AHCI and ATA, but both STILL produce ANOTHER problem: installing Windows recognises the hard drives, but it never rose from 0% of the phase of "expanding files" installation.

  Please, can anyone help?

• Can't see stereo mix on Dell Inspiron 7520

  Hello

  I know it is a problem that lasts for years and I googled and read a lot of forum posts on this topic but I still can't understand.

  I have a new Dell Inspiron 7520 and I want to use the stereo mix function, so I can record audio coming out of my Conexant SmartAudio HD card.

  I tried to open the driver and .inf file commenting on these three lines:

  HKR,%EPattributePath%\EpSettings\StereoMixEnable,enable,1,01

  HKR,%EPattributePath%\EpSettings\StereoMixEnable,MixAssocSeq,1,E0,E0

  HKR,%EPattributePath%\EpSettings\StereoMixEnable,MuteGainSettings,1,00,00

  I then go back into Device Manager and re - install the driver Conexant by accessing the location of the .inf file that I just edited (by removing the comments of semi-colons). But I get the error message: "Windows found driver software for your device but encountered an error while attempting to install it - Conexant HD Audio - the system cannot find the file specified. '. Just before I noticed it says that the driver is not signed, which could be a problem as I have Win 7 Home Premium 64 bit.

  Any advice greatly appreciated.

  I got it to work!

  The solution involves the file the modified driver .inf and re - install this file. Here, I explain what I did in case anyone else has this same problem. This should work for any Windows 7 64 bit computer with the Conexant HD sound card and driver Conexant HD even though I only tested it on my own computer.

  My problem:

  New Dell Inspiron 7520, Win 7 Home Premium 64 bit, Conexant SmartAudio HD sound card with the last driver Conexant Web Dell Drivers site. Stereo mix would not appear in Control Panel > Sound > recording even tab after a right-click empty space and selecting display disabled and show disconnected devices.

  Solution:

  Make sure that you install the Conexant HD SmartAudio driver. You should see it under the sound, video and game controllers in Device Manager. With the Conexant driver already installed and the key work is to find the exact location of the driver file. It can vary from one computer to another and also be called something else. Mine is called chdrt.inf and it was located in: C:\Windows\System32\DriverStore\FileRepository\chdrt.inf_amd64_neutral_fa34defac299c440

  If you don't know where your .inf file, you could do a search for windows for text in files of the string: EpSettings\StereoMixEnable. It will most likely be a file with a .inf extension and located in a subfolder of the System32 folder.

  Right-click on the name of the .inf file and select 'Open with' then choose Notepad. Press Ctrl + F and search for StereoMix to find three lines:

  ; HKR,%EPattributePath%\EpSettings\StereoMixEnable,enable,1,01

  ; HKR,%EPattributePath%\EpSettings\StereoMixEnable,MixAssocSeq,1,E0,E0

  ; HKR,%EPattributePath%\EpSettings\StereoMixEnable,MuteGainSettings,1,00,00

  Delete the semicolon-->; and save the file. However, Windows doesn't allow you to save the .inf file unless you change the permissions of files. It becomes complicated and a little dangerous!

  Basically a right-click on the .inf, then click these buttons/tabs... Properties > Security > advanced > owner. The current owner should be TrustedInstaller. Change this account on your computer that has administrator rights, and you can connect as long as. To do this, click on change and in the "change in ownership to:" field there an entry should be there as: Administrators (name\Administrators of your computer) to select that then Ok and apply and Ok to close the dialog boxes.

  Now right-click on the .inf again file: properties > Security > Edit > select "Everyone" in the "Group or user names" > check the corresponding box to 'Write' in the 'Permissions for everyone' section > press Apply and OK your way to close all the dialog boxes. Now you can save the .inf file, you remove the semicolons of!

  This step is VERY important. You must change the return of the permissions to the way they were. Right-click on the .inf right and as before changing the write permission by deselecting the checkbox for 'Writing', and then change the property of the .inf file back to TrustedInstaller. This time you'll owner > Edit > other users or groups and type NT service TrustedInstaller in the box and press on check the names, then Ok and apply your way out dialog boxes.

  Now finally, re - install the driver: here I had problems with the driver not being recognized and maybe it's because Windows 7 64 bit has said it is not digitally signed so here's what I did: Start Menu > right click on command prompt > run as administrator > type this command and press on... Enter bcdedit/set nointegritychecks WE.

  To install the driver: Device Manager > sound, video and game controllers > right click on HD SmartAudio Conexant > update driver software > Browse my computer for driver software > let me pick from a list... > Have Disk > Browse > now, here, you have to find the location of the .inf file that you just edited, in my case, I stuck in the path to the folder and press on enter then select the chrdt.inf file and click OK. When it was installed I went back to the command-line as before and run the command: bcdedit/set nointegritychecks OFF

  Now, I rebooted the computer and this time stereo Mix appear in Control Panel > sound > recording after right click tab empty space and selecting display disabled and show disconnected devices.

• SG300 switches have poor performance in layer 3?

  We have several switches SG300 Serices. We use them to route traffic to VLAN remote offices, the Internet connections and wireless access Points.

  In a remote office, we have a SG300-10 facility to route the HQ network and the remote office subnet. The SG300 is connected to the seat through fiber and contains several VLAN Tag. If I speed, tests on the fiber of the entrants Netwotk tag link I get decent performance, 80Mbs. If I switch to a networtk who is not priginating of the central administration and road SG300-10 package, I get poor performance. 15 - 20Mbs.

  I have Fireded until a new FW SG300 - 28 p v1.2.7.76. Added a HQ VLAN 101 and VLAN new, 1025. Mapped some Tagged and not marked for each ports.  Switch has been connected to the network of HQ as untagged VLAN 101.  I put a laptop on a unmarked port VLAN 101. Ran some tests, cam is back with 750-850Mbs. great.  Put the same computer laptop on a Port of 101 tag, set the NETWORK card for tag VLAN 101, same test, same speed, 750-850Mbs.

  I configured then laptop for tag VLAN 1025. Connected to the port 1025 VLAN scored. Done speed tests, the results were 15-20Mbs!

  Then I configured laptop for Untagged VLAN 1025. Connected to unagged port 1025 VLAN. Done speed tests, the results were 15-20Mbs!

  It was only the laptop and connect to the net on the SG300 - 28 p P.C. Why this device's performance is so poor when he needs to route?

  Other switches have v1.0.0.27 FW or FW v1.1.2.0. They have similar speed problems. All configured for layer 3.

  Thank you!

  How are customer gateways and server configured?

  The default gateway for connecting devices should probably be that of the IVS, they are directly connected to. So if you have a server connecting to a SVI 192.168.1.100 then the gateway server should be 192.168.1.100, not a router upstream. Who can create a loop of road if the return circulation.

• VPN poor Performance - Cisco RV220W and routers WRVS4400N

  Hello

  To one of our customer IPSec VPN is established between Cisco RV 220W and routers of Cisco WRVS4400N.

  Router VPN /ISP details are as below

  Location was	Location B
  Details of the Internet ---------------------- DOWNLOAD: 6 to 10 Mbps Upload: 1 to 2 Mbps Details of router ---------------------- Cisco RV220W Firmware: 1.0.3.5 IKE policy Encryption: 3DES Authentication: MD5 Group: Group 2 Life key: 28800 sec VPN strategy Encryption: 3DES Authentication: SHA - 1 Group: 1024 bits (Group 2) Life key: 3 600 s Perfect Forward Secrecy: enabled	Details of the Internet ------------------------- DOWNLOAD: 1.35 Mbps Upload: 1.24 Mbps Details of router ---------------------- Cisco WRVS4400N Firmware version: V2.0.1.3 Phase 1 Encryption: 3DES Authentication: MD5 Group: 1024 bits (Group 2) Life key: 28800 sec Phase 2 Encryption: 3DES Authentication: SHA - 1 Group: 1024 bits (Group 2) Life key: 3 600 s Perfect Forward Secrecy: enabled

  From the day that VPN has been implemented, the performance was poor. Frequent disconnections sessions live to the VPN nodes and very low transfer rate was alarming to users.

  The servers in A location and users to the site B gets authenticated at the server DC level in A location

  Applications of Terminal Server remote as Quickbooks, QQ Evolution, attendance RX serve also the location has by users to the location B

  The login is your time and all applications are extremely slow.

  I tried to copy files between share data between two locations and the results are as follows

  Location A to location B-> 130 Kbps 140 Kbps

  Location location B A-> 150 Kbps to 160 Kbps

  What can be the problem for these poor performance VPN?

  -Change the encryption for the least secure OF THE /MD5 would have a significant impact because it can reduce the overload on the routers?

  -Even if both routers are routers SMB, it has really good VPN flow according to the data sheets. I couldn't find VPN flow mentioned in the WRVS4400N data sheet. One of the sons of CSC, I also noticed the VPN of WRVS4400N flow seemed really low as only about 1.6Mbps. (https://supportforums.cisco.com/thread/2107881)  Whereas RV220W router has VPN 90Mbps flow, according to the datasheet.

  So, what can be the cause of the problem and what can be fixes possible?

  Help, please!

  ANUP sisi

  Beginner to router Cisco VPN, please help

  RVS4000 was designed to work in a small office. It supports 5 VPN tunnels with a maxium of 2 Mbps flow measured in a laboratory environment. It has a processor that has a motor integrated IPS, who would deliver 20 Mbps LAN - WAN throughput when IPS is enabled.

  RV220W has been designed to operate in a slightly larger office with 25 IPsec VPN tunnels. It has a processor that has a built-in cryptographic engine able to deliver throughput 90 Mbps of IPsec. RV220W also supports 5 SSL VPN tunnels that can be used by employees and business partners for remote access.

• Poor performance Alienware 13

  Hello, I have recently updated my Asus G55VW to 13 Alienware and he's surprisingly poor performance in some games from my old laptop. As far as I know that I put everything to max performance but it is still low in some areas.

  Old sheet

  Intel i7 @ 2.5 GHz to 3.4 GHz

  NVIDIA geforce 660 m

  8 GB ram

  Alienware 13

  Processor Intel i5 1.7 GHz to 2.7 GHz

  NVIDIA geforce 860 m

  8 GB ram

  So far, Borderlands 2 runs poor while others like Warframe can operate at max settings no problem.  Other games like naruto shippuden ultimate ninja storm 3 full bursting cannot run because it selects only the integrated graphics card and I can not change... Right now, I think that the graphics card integrated into the issue and if there is a way to disable it, which could make things much better. Not to mention that any help to increase performance would be greatly appreciated.

  JLM264

  Alienware 13

  Processor Intel i5 1.7 GHz to 2.7 GHz

  You have a 1.7 GHZ dual core CPU... Borderlands 2 recommends the use of 2.4 GHZ quad core CPU

  Your "old" laptop ASUS who had a 2.3 GHZ quad core CPU meets this requirement more than your new machine

  Warframe works very well, because any CPU dual core is sufficient and that's what you have

• Poor performance InternetExplorer9

  Hello

  I have my InternetExplorer9 on a clean Windows7 VM thinapped and have Veery poor performance when I run the finished app.
  I tried many things to increase the speed. My normal ie9 starts in 5 seconds, until it's on google.com, my thinapped however ie9
  needs about 10 seconds, even after the restart of the 5th. What I've tried so far is:

  -J' have compressed the ie9.exe when generating

  -J' put 'AutoStartServices = 0' in the Package.ini generating

  -J' put 'NetRelaunch = 0' and 'AutoStartServices = 0' in the Package.ini.

  -J' set the sandbox sand-path %appdata%\microsoft\windows\sendto and the local path (tried both)

  -J' deleted some unnecessary user-specific folders in the project path

  -J' got only InternetExplorer.exe as entry point

  I tried the last few steps of each constellation, but no finished package is better than the others. You have any other suggestions for

  My problem? (I use the Thinapp_4.7.2 by the way)

  Kind regards

  It doesn't matter as long as it is in the right section:

  [Compression]

  CompressionType = None

  [Segregation]

  DirectoryIsolationMode = merged

  [BuildOptions]

  OptimizeFor = mΘmoire

  DisableTransactionRegistry = 1

  I forgot to mention it, but there was a new feature of Internet Explorer 9: hardware acceleration.

  Change IE9 to disable hardware acceleration has helped me get better performance in my VDI environments.

• Android apps have poor performance

  I have several applications created for Android and all my folios seem poor performance on android devices. It takes a long time for any article to focus on the text (all sheets are built using PDF), and there is a significant for interactivity in a Folio delay, if it does not crash the app entirely. Has anyone else had problems with Android apps? I have not read a lot of useful information on them.

  All my applications are built for android with the dimensions of 2048 x 1536 to make them readable on the Nexus-10. All applications have been rebuilt with v27 and PDFS.

  I'd appreciate comments you can give.

  Thank you

  One thing that can help with the Active Viewer is to design to a smaller size (1024 x 768, for example), use a PDF object and the viewer intensify folios to fit larger screens. Put scale up to adjustment is supported in our 28 Viewer version of AIR and it makes a big difference in performance while maintaining the reasonable quality of the assets.

• Problem with the AMD Radeon HD M 7730 Inspiron 7520

  I just got my new laptop Inspiron (15R) 7520, when I watched the display settings in DXdiag and in dell support center it says I have the Intel HD Graphics 400, when I had to get the AMD Radeon HD M 7730 graphics driver, I asked a friend who said he could be in there but its not picked up Anyone know why?

  The specs for the laptop are here: http://www.dell.com/au/p/inspiron-15r-se-7520/pd

  That's what dxdiag shows me:

  

  Switchable graphics do not work, you can hear intel HD4000 on the parameters of the program to start with (and on the win7 experience index), but once you are in the program/game the computer will use the 7730 m.  Programs like 3dmark06 and games like Skyrim will show intel HD on the initial configuration page but the 7730 m should then launch - an easy way to see if his job is to compare the performance with her was put in power save instead of perfromance and you will see a difference in frame rates...
