I have the following issue with my Gigabyte C246M-WU4 (Display Port) and Intel Xeon E-2144G. If I set a resolution of 5120x1440, this leads to graphic errors or even a crash of the IGP when the decoder built into the IGP is used, e.g. B. when I use the Windows 10 Netflix app. I then have to open the task manager via CTRL-ALT-DEL and have a picture again for 1-2s, in this time I have to close the app, otherwise the picture will turn black again. The problem does not occur if 3840x1440 or 3840x2160 are set. Normal desktop applications however are working properly.
The problems already start when you open the Netflix site in Chrome or Edge. Then the picture begins to twitch. In the task manager on the right, the IGP is shown in "Video Processing" mode on this page. It is strange that the flickering disappears when you drag the Task Manager window over the browser window:
But apparently it makes a difference whether you are watching a movie on Netflix (here: Blade Runner 2049, works) or a series (here: The Blacklist, does not work). I don't know why, but I suspect that different codecs may be used because films are longer and therefore a more efficient codec is probably used:
It was also noticeable that when playing in a non-maximized window the problem does not occur at first. If you then enlarge the window, the known problems begin:
The fact that it has nothing to do with Netflix can also be seen in this blatant example:
You can see very briefly how it switches to "Video Processing", then the picture first turns green and then black:
The latest Intel graphics driver was used. Windows 20H2 is freshly installed, all drivers are up-to-date, BIOS up-to-date. A Displayport as well as an active DP-> HDMI cable were tested. I suspect that among others the Netflix app and website (but also the other link mentioned) use a decoder function of the IGP for a certain codec. That would explain why this problem does not occur in desktop or normal browser operation.
Is anyone able to help`?
Thank you for posting on the Intel® communities.
We understand you have opened a web portal internal case with us and we will continue to help you through that channel now. We will therefore close this community case.
If you need any additional information, please submit a new question as this thread will no longer be monitored.

so far you colleague working on the internal case was not really helpful, instead of trying to help with the issue he just wants to convince me that this resolution would not be supported although it is officially stated by Intel that it is supported and it can be used without any issue. My problem is a very specific use case which needs some deeper analysis.
