The combination of a Geforce graphics card from Nvidia and a UHD monitor can cause problems. The Geforce series from GTX 700 up to and including GTX 1000 are affected.

You will often see image errors here on the monitor connected to it with a resolution of 3840 x 2160 pixels – for example a sudden black screen that disappears after a few seconds, or a frozen image when you switch on your PC. But don’t worry: neither your monitor nor your graphics card are broken. The error can be eliminated.
First of all, check whether the connected video cable is correctly seated on both the screen and the graphics card. Even a slight loose contact can make the ad twitch. We also recommend that you always use the connection cables from the monitor manufacturer, which are included in the packaging.

Ideally, you should use the Displayport connection type. However, this is exactly where another source of error can be hidden – at least in conjunction with the aforementioned Nvidia graphics card series. The manufacturer has already recognized the problem and is providing a free firmware update that can be found on
download (a version for 32-bit operating systems is also available on the site). With the update, Nvidia unlocks full support for Displayport versions 1.3 and 1.4, which should make image errors a thing of the past. It is particularly convenient that the free tool automatically detects whether the graphics card needs the newer firmware at all, and the installation then takes place.
If the UHD monitor still has dropouts, freezes or flickers, you should check whether the PC power supply unit supplies enough energy for the entire system. That sounds strange at first, but it can be another cause of errors. Corresponding calculators for power supplies are available on the Internet – for example from the manufacturer Bequiet. If necessary, replace the power supply with a more powerful version.
For high-resolution screens, the display port connection and the use of the monitor manufacturer’s cables are recommended.
Only if these measures do not help is there a defect in the monitor or graphics card. If possible, borrow a different graphics card (ideally the same model) and a screen with Ultra HD resolution to confirm the suspicion. After that, you will know which device is causing the problems.
