Intel HD630 crashes while video decoding in 5120x1440




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.


How can this issue be solved?

Hello @stna1981

Thank you for posting on the Intel® communities.


We found that you have an internal case describing the same issue and the same hardware/software environment as the one in this thread and Intel® Customer Support already assisted you through the internal case.


Checking the internal case, we understand your concern about the support of resolution 5120 x 1440 as per the information in this article: Native Resolution 5120 x 1440 Not Available with Intel® Graphics.


The Maximum Resolution Supported for your Intel® Xeon® E-2144G Processor with Intel® UHD Graphics P630 is 4096x2160@24Hz for HDMI® and 4096x2304@60Hz for DisplayPort* (DP), also known as 4K Resolutions. Higher Resolutions are available in newer Processor/Graphics, for instance, 5K and 8K through DP on 11th Generation Intel® Core™ Processors.


The horizontal resolution 5120 is the setting for 5K on Intel drivers. It needs two display ports to function properly. Panels with 5K and 1 display port (5K with a single port) are not supported by Intel and have never been verified or tested internally on Graphics that don't support resolution higher than 4K.


As a reference, please review this link: Horizontal Stripes and Flickering When Watching Videos Using 5K Resolution.

We noticed that 3840x1440 or 3840x2160 work fine when you select those resolutions. That is the expected behavior and this actually matches one of the suggestions in the article above.


In regards to the resolution 5120x1440, our recommendation is to contact your display manufacture for more information about the display and capabilities.


Best regards,
