XPS 15 9550 with 4K display levels of good black out

I bought a new XPS 15 with the infinity display 4 k, and for some reason, the computer laptop screen suffers from black and white crush extreme. I tried to calibrate the screen, and it seems that the lowest and the highest video are be cut. As a result, the dark areas of an image to merge with absolute black creating terrible color banding and pixilation in shadows of images.

I tried to make adjustments in color first dell windows (tried to uninstall it as well), internal display settings, control panel of the integrated graphics card intel, and none of them made the difference. Even with the brightness, contrast or show black max level in video settings more weak are indistinguishable from absolute black. Even the opposite ends with white.

The issue is identical to the output of the wrong video level to a screen (for example to display the range complete pc to a regular TV with limited series), but I see no way to resolve internal laptop display settings.

For the record, output levels from black to a TV via HDMI are thin, so it's clearly a problem with the signal to the computer screen or laptop display itself and not a problem of overall system.

To be clear, this is an extreme amount of clipping. I understand that most of the screens cannot output a video full range of 0-255 without some bands. However, on my laptop, it's so bad that anything containing the shadows looks terrible. Photos even without compression of space have terrible pixelation that makes it looks like these images 4 bits from the beginning of the 1990s.

My problem is solved now. The culprit was the drivers Intel HD Graphics 530 (version 20.19.15.4390, released 18/02/2016). I use an old version (20.19.15.4331, published on 18/11/2015).

The clipping, banding has been completely remedied. The system is occasionally and will prompt to install the new drivers. I'll have to hold on to the next. I don't know if there's a degradation of performance elsewhere.

  • XPS 15 9550 with black screen problem

    Hello

    I have a XPS 15 9550 UHD, 512 GB SSD and using the laptop without major problems for 3 days. Today, I tried to start in safe mode for windows and you press the F8 key at random on the departure. It has not worked and I retried the boot. I could randomly pressing keys like F5-F6-F7-F8 function, etc.  But now the screen is always black, no sign of any connection Logo Dell or bios. I see that power exists on the laptop, fans run, there is on the keyboard lights up but the screen is black and there is absolutely no sign of boot.

    I also press and hold the FN + start button / stop. It did not work. I tried but its not start. What could be wrong here? Remove the battery (I hope that security will not be cancelled if I open the back of the laptop) and retry the turn a good idea?

    BTW I bought this laptop in the United States and return to my country Turkey. The DELL warranty is valid internationally?

    Best regards

    Try to press and hold the power button for about ten seconds, release and press it again. If I remember something like this happened to me recently, and I think it's how I solved it.

    BTW, F8 to enter Safe Mode has been disabled in Windows 10. You can hold SHIFT while clicking on the power > restart links on the login screen or the Start Menu (on the left or right, click on the selection) and then enter in the troubleshooting section. The other option is to change BCDEdit.

    EDIT: I just now experienced some strange problems on this site. From time to time if I right click on one of the posts to choose open in a separate tab, the select box (which has a number of other selections) is completely or partially black. I have never seen it before. I use the latest version of Firefox as my browser.

  • Is this normal for XPS 15 9550 screen quality?

    Good evening.

    Last month I bought the XPS 15 9550 with a 4K screen and it had a red tinge in the corners of the display surface, which was visible in a bright room with me, just sitting in front of it. I thought that I have received a defective unit and arranged a replacement through Dell customer support and yesterday I got a new one. However, it has exactly the same problem. To understand what I'm talking about I enclose a picture of the screen. Black background, no external light sources, average brightness.

    Smart phone camera exaggerates this effect a little bit but it is still very noticeable to me. I'm talking even on ghosting and consultation of top / sides when black past completely in red, honestly, I could live with it, but that distortions of color at this angle... I expect too much of a £1,800 laptop? It is worth to try another replacement?

    Not normal. RMA and hope for better luck.

  • XPS 15 9550 upgrade parts

    I just ordered a XPS 15 9550 with a processor Core i5, 8 GB RAM, 1 TB + 32GD SSD and Gefore GTX 960 2 GB. I don't want to use for the games as well as work, here are the updates I had in mind:

    RAM: add another 8GB (Dell store it for ~ $ 75)

    SSD: switch to 256 GB (Amazon ~ $125)

    Graphics card: 970 or 1060 (Amazon ~ $ 350-500)

    I "ve never done before upgrade parts, so my question is should I take into account when these purchases (don't like each 8 GB RAM I find can be used in a laptop, etc.)." Are there specific things that I need to look out for when buying these regarding the dimensions and compatibility?

    The agent assured me I can upgrade these, but honestly, I can't really trust their knowledge on these things.

    Please let me know your thoughts, I can still cancel the order if I can't do these updates that are important to me. Thank you!

    The 8G, you have now is probably 2 X 4 - so to upgrade you get 12G, if you replace a 4 by 8.

    You will probably not find any SSD PCIe m2 worth buying for $125--ça is going to be more in the range of $175 to 200 for a decent (Samsung, Intel, Crucial, Sandisk) SSD PCIe m2.

  • My MBP with retina display has no top file, but storage information still show a lot of memory being exhausted by audio, photos and movies.

    Recently, my MacBook Pro with retina display has started to run out of memory, so I moved all my downloads and stuff in my external hard drive. After the transfer, I had some good 20 GBs free and my folder all my files to completely empty.

    But even now when I go into storage under the about this Mac information, it shows that more 1 GB of audio files, about 800 MB of photos and 500 MB of movies.

    Using the search option (and put a black space in the search bar), I discovered a few files in the Mac section, but they were barely a few MBs in size, and no audio or images or movies were present there.

    Where are all these "hidden audio, photographs and films that take about 3 GB of space from my hard drive? I am naïve.

    Here is my overview of the system:

    Any help will be much appreciated.

    This view will be incorrect until the Spotlight indexing your drive. In addition, it is only an effort to classify the files types are known by their file extension. Thousands of files on the computer, however, will only be classified as 'Other' because they did not have a type that falls into one of five or six available categories. If you want an accurate display of disk space then: press command-I to open the window read the information. In the top panel is a visualization of the status of your drive: capacity, used and available. It's everything you need to know. If you want information on the types of files and their location, and then use a tool such as OmniDiskSweeper or GrandPerspective.

  • XPS 15 9550 CPU speed is as low as 0.75 ghz after manually installed windows 10 with all the drivers installed and BIOS updated

    I just bought this XPS 15 9550 in January, and I really appreciate it at first.

    However, one day, as pushed microsoft update to 10586 version of windows 10 and the machine will always fail to install the update, so I decided to download the image file and install it myself.

    The installation went smooth, but after a few days use, I found the computer is very slow during playback of videos and games and I came to find the speed of the CPU shows the label of performance in the Task Manager always will be 0.75 ghz and 0.78 ghz. He cannot go above that. I also found that the use of the CPU cannot exceed 30%.

    I've already updated my BIOS to 1.1.19, reinstall the system, a few times, choose the battery mode high performance, etc and this does not help.

    I also downloaded the power of intel and found gadget for my processor power consumers are still weak and the speed of the CPU is always not 0.80 ghz.

    In addition, I encountered the problem that after plugin the AC power, the speed of the CPU will fall to 0.39 ghz...

    Someone at - it an idea of what is happening here and how can I solve the problem? I'll really appreciate it. Thank you.

    I had my problem is solved. Follow these steps:

    1. download gadget power intel, you can search online for it.

    2. check the power of your CPU (package pw...) rate and open the videos and applications that will constantly consume the CPU power. See if the power is still weak.

    3. If the power is still weak, try to update your BIOS (download dell drivers and the new version should currently be 1.1.20) and see if things are getting better.

    4. If the power is still low, you must contact dell technical service to replace your hardware (my computer has replaced the northbridge, southbridge, I forgot, but after replacing, the CPU works fine)

    Note: If you run games using your discreet graphics card, such as starcraft II and you found that it's extremely slow, it is possible that your cpu is capped.

  • XPS 15 9550, P2415Q, sleep problem

    Hello, I recently bought a Dell XPS 15 9550 and a 4 K of Dell's Dell monitor. The monitor is connected to the XPS via HDMI. I use this phone more like a desktop computer, it is connected directly to the router.  The monitor goes to sleep after one minute of inactivity. I gone through all settings to never go to mode "Eve". The XPS screen will not sleep but briefly flashes white but then returned to the screen blanker (Webshots) but the monitor still expires at a minute with a blank white screen.  Movement of the mouse, the screen turns on, Webshots stops and displays the current screen. The monitor is set up for clone display XPS.  Suggestions?

    What resolution is running the monitor? It should be the default value of resolution HDMI 3840 x 2160 30 Hz. open the OSD (On Screen Display) display - display. It must be defined on the primary.

  • Dell XPS 15 9550 battery not charging

    I recently got my XPS 15 and was messing with the settings of the BIOS for the life of the battery.  I changed the Adaptive mode to custom loading, about 80 to 90% thresholds.  When I booted my machine, the battery indicator on the taskbar displays "connected, charge", but this is clearly not the case, as the battery life gradually decreases as if it does not load.  In addition, it no longer displays the estimated remaining time, but 'calculation. "... ».  I tried to return to the Adaptive mode, but it still has the same problem.  I also installed the Dell power management program to see if that helped things, but there is not.

    Someone else has had this problem after changing the battery settings in the BIOS, and how do I fix?

  • Satellite Pro U200: dark shadow with the lowest level of brightness

    Hello

    Now, I have another problem with the display of my U200:
    In the lowest brightness level, there is a dark shadow on the left side. I can see it after a few minutes of work at this level of brightness. Two months ago the display has been repaired or replaced by TOSHIBA.

    You know this problem or could someone test it please if this is normal or not? In the other levels of brightness, I can't see a shadow.

    Thanks in advance, Michael

    Hello

    Have you noticed these shadows before the repair screen?
    I m not a Pro U200 owner and, therefore, I can not say much about this issue, but on my laptop, something similar appears if the brightness is set to lowest level.

    In any case, I recommend you to call the guy who repaired the display. Maybe they know more about this issue and could provide details.

  • (Redirected) Dell XPS 15 9550 - battery problems

    Have been a customer for a long time of the Dell laptops.  Bought various laptops such as Vostro 1720, XPS Duo 12 etc.

    I bought the XPS 15 9550 on 27 June 2016 after costing a fortune.

    Immediately noticed a problem with the battery life that is loading / unloading quickly.

    The first time, got battery in full in a few minutes.  After recharging, at the beginning he said battery life is 4 hours. But the battery discharged within just two or three hours of time.

    Since then, battery charges to the full in about 30 minutes and ends in less than 2 hours.

    Because my laptop is still under warranty, I raised a ticket of support immediately on June 29, 2016.  Unfortunately until now, I didn't reply to Dell.

    Please can you help solve this battery issue.

  • UP3216Q, XPS 15 9550 HDMI out, can't get 3840 x 2160 60 Hz?

    I just got this ULTRA EXPENSIVE monitor, 2500 + tax from Dell, which cost of superior quality!

    The drivers installed and right from the GET go, I can't get the maximum resolution with 60 Hz refresh rate. The screen is extremely slow.

    I have the new laptop Dell XPS 15 9550, which is connected via HDMI 2.0. 'Works' except that I get 60 Hz @ 2048 x 1152, but as soon as I chose 3840 x 2160 I get only 30 Hz maximum. What gives? I have a cheap UHD 4 K monitor I bought for less than 1000 which can make max resolution @ 60 Hz...

    If it's the best this thing can do, I have to go back! $ 2,500 for 30 Hz?

    With the help of 10 Pro 64-Bit Windows. If anyone can help that would be great! It is not normal... I am hooked directly on the screen of my laptop, I have not the TB15 docking station because it's still not available in the Canada, but I'm not sure that it would even help.

    My E7240 Latitude has the same problem. But that's because the HDMI output on the Latitude E7240 is version 1. 4A. The customer I find State that the output HDMI of XPS 15 9550 is only version 1. 4A, not 2.0.

    Do you mean only by using the XPS 15 9550 output HDMI, you reached 3840 x 2160 60 Hz on the other UHD 4 K monitor?

  • Upgrade SSD for Dell XPS 15 9550

    Hello

    I have Dell XPS 9550 with configuration 32 GB SSD + 500 GB HARD disk. I want to upgrade SSD for more space avaliablity.

    But I don't know what type of SSD, I'll need to buy. Also, I read XPS 15 to repair. There are two chapter for the removal and replacement of the SSD in the maintenance manual. First chapter of half-length SSD, second chapter SSD full length.

    What type of SSD is mounted in my laptop? Half or full length?

    How can I identify necessary SSD for me in stores (dimensions, label, etc.)?

    What interface for SSD do I need?  PCIE or SATA?

    What is the map? M2.2280 or PCI-E AIC (-expansion card)?

    Thanks in advance!

    These are all numbers of Dell and descriptions.

    The system uses a PCIe (or is if you want a faster player), 2280 m2 or small size.  UNLESS you buy directly from Dell, it is best NOT to buy versions OEM of SSD (Samsung end pieces in a '1' vs '0' for details).

    OEM spare parts are usually not compatible to end-users by the manufacturer.

    Because you will probably install the operating system for the new SSD, don't forget to make a recovery media set, you need to load the operating system on the larger capacity disk - what you have now is just a cache for the main hard drive.

  • XPS 15 9550 - TPM "disappeared".

    After receiving my XPS 15 9550 about six weeks ago, I immediately enabled BitLocker w/TPM. Which was working fine until a week or so; I was invited all of a sudden for the recovery BL key after having the laptop off for about 24 hours.

    Consecutive restarts kept asking the recovery key. Finally, I tried suspending protection BL. Trying to take it back, I got the error message "no security of the TPM secure mechanism were found on this computer". And of course: TPM has been put as a device "hidden" in Device Manager, try to re - activate it led to the same error message. Also, I was unable to find any mention of TPM in the BIOS.

    No hardware changes or upgrades to the BIOS didn't had been played when this problem occurred.

    I tried earlier to upgrade the BIOS version 1.2.0 to 1.2.2 (later), but without success - the TPM is still missing from the BIOS. I also tried to restore the settings to factory, but with the same result.

    Finally, I got a hold of a Dell technician who was able to understand my problem. I was told to make a laptop computer power cycle: remove the battery, remove the memory sticks and finally press the power button for a good 30 seconds. Then wait 30 seconds before put you everything back together.

    In other words, only a full reset CMOS. But it worked! After starting the TPM module, options were "Safe" in the BIOS.

    I still wanted to know what caused this in the first place however.
