U2713H, works as a secondary mode Clone and extended screen

I have this strange behavior with the Dell monitor and do not know what is happening. When I put the monitor as the primary display, I have a white screen, but if I put it as a Clone or extended than what it runs. I already bought a new display port cable, but I get the same behavior. Everything worked fine a few days back. I tried to reset the monitor and nothing.

Any ideas?

By the post-it, you reset the screen as indicated? The monitor had managed to self-test and SUBMISSION (built-in diagnosis)?

* What computer model is the monitor connected?
* What operating system?
* Which video card?
* What are the ports are available on the video card?
List of every cable that connects the monitor to the computer

  • Why some games and other programs need to be "run as Administrator" mode in 7RC which worked fine in normal mode on 7 beta and vista?

    Why some games and other programs must be run in Admin mode in 7RC which worked fine in normal mode on 7 beta and vista?

    An example of this is the game Guild Wars (www.guildwars.com). I had problems with this with random programs.

    cbello57,
    Run as administrator may be required for some games and programs because they have a permission structure different in Vista in Windows 7 (Windows 7 and Vista are different in how to manage certain permissions).

    I suggest test you installation of the game in the program by clicking on the Setup file by clicking on "Run as administrator".

    This will sometimes solve this kind of situation because it installed the program in a State of high permission.

    This output from test and let us know your results Rami

  • iMac works fine with safe mode only

    iMac works fine in safe mode, but in normal mode, it freezes constantly, the wheel that turns, the freezing of the apps, and when I try to restart, it gets stuck. I have to hard reboot. I tried to reinstall the operating system, which did not help. I have reset the NVRAM, but it has not solved the problem. I came across another post in 2013, with another user who was having a similar problem. There are detailed instructions to run diagnostic tests via terminal and display the results. This seemed to fix the problems of the user, but I don't know what to do with the information it generates. I have an iMac 2009 El Capitan 10.6.11 running. Can someone help me understand what the problem is?

    If you have any type of antivirus, cleaning or ANY other third party maintenance application installed, please find the developers instructions and uninstall. At best, these types of applications are 100% useless and at worst they cause more harm (similar to what you are experiencing) than good.

    If you don't have one of these types of applications installed, run a report of EtreCheckof your system. We then look for obvious problems. Please click on the link, download the application and run the report. Once you have the report, please copy and paste into your response to this post.

    Please see recommended settings of WiFi routers and access Apple points.

    Despite these recommendations, some routers will work better with the latest Mac models if you turn the radio 2.4 GHz mode in settings and only use the 5 GHz. Note, however, that very old devices Apple and some third-party devices can then not connect at all.

    Some third party routers have advanced that you may need to change the settings:

    The encryption algorithm must be AES.

    The group key interval must be 3200.

    I can't give you specific instructions on how to change these settings, because all routers are different. Refer to the documentation for the provider.

  • MediaTek MT7630E 802.11bgn adapter Wi - Fi does not work in 802.11n mode (mode-N), only G-mode

    A few days ago, I got a new notebook HP ProBook 430 G1. OS: Windows 8.1

    They have Mediatek MT7630E 802.11bgn Wi - Fi adapter inside.

    Problem: I found this wireless adapter does not work in 802.11n mode (mode-N), but works well as in G-mode.

    Some modifications in the parameters of the driver on the Advanced tab are problem solved.

    I think it's a bug of material, or (less maybe) a bug in the driver.

    In other forums, I heard that HP can replace the card wireless, which works well. Is it not?

    You misunderstood me. I meant, of course, all channels from 1 to 13.

    I solved the problem by unistalling completely all the WiFi and software of the device with its drivers from Control Panel.

    Then downloaded latest drivers from site oficial Mediatek.

    In the Advanced tab of the new driver settings option appeared - "802.11n direct mode.

    After you enable this mode WiFi started working in mode N well.

  • Auto focus does not work in the creative modes

    I use EOS 600 d for the past three years. I was and I am not able to auto focus in creative modes. I actually thought that there is no installation of the auto focus in creative modes. Only when I attended a workshop in Chennai yesterday, I got to know the automatic update facility is available in creative modes too.  I tried with three lenses and in all cases autofocus does not work in the creative modes only. In basic mode, it works well. I browsed the forum and found to RESET. How a reset should be done? Someone please explain. I can't find any updated firmware for 600 d.

    Thank you, Mr.Waddizzle. I did a reset according to your advice and now AF works in the creative modes also. Thank you.
