Experiencing Video Dropouts with 5K Monitor on Maximus XIII Hero (i9-10900K)

Hi everyone,

I'm using a Maximus XIII Hero motherboard with an Intel i9-10900K CPU (using the on-chip graphics, Intel UHD 630) and no dedicated graphics card.

Recently, I purchased a new 5K monitor. While the i9 CPU supports 5120 x 2160 resolution, it can only output this resolution via Thunderbolt on the rear panel.

I'm using a Thunderbolt 4 cable connected to the monitor's Thunderbolt 4 input. While everything seems to run well initially, I experience complete video dropouts for 2-3 seconds, indicated by a reconnect symbol on the monitor display.

To troubleshoot, I've tried the following:

- Replacing the Thunderbolt 4 cable with a Thunderbolt to DisplayPort cable (same result)
- Trying different 5K monitors (Dell, Lenovo, Philips) - still facing the issue
- It seems the dropouts might be correlated with the video content being displayed

I'm hoping someone here might have encountered similar issues and can offer insights on how to fix this problem. My motherboard BIOS is updated to the latest version (2001, dated September 21, 2023).

Any suggestions or experiences you can share would be greatly appreciated.

Thanks!

Hello, @Mole65 

According to the official specifications of your current Intel® Core™ i9-10900K Processor:


The CPU supports 4K resolution, and the Max Resolution for HDMI is approximately 4096 x 2160@30Hz, while the Max Resolution for DP/eDP is 4096 x 2304@60Hz.
However, 5K resolution is 5120x2880, which may not be adequately supported for output.
We recommend cross-testing with a dedicated GPU or other monitors with 4K resolution to further assess the situation.

Thank you.
