I purchased a Beelink SER6 Max mini PC that is unable to support 240Hz refresh rate without flickering or failing in some fashion (5120x1440p) on Samsung G9. See this video: https://www.youtube.com/shorts/iN4oVoGVGtg
The issue is not the monitor, not the cable (Thunderbolt 4) but either a defective beelink mini pc (craftmanship issue) OR the CPU doesn't support it. I would be shocked of the later to be true since my i5-11320H Intel mini pc can handle 5120x1440p@240hz just fine.

AMD Ryzen™ 7 7840HS: https://www.amd.com/en/product/13041
DisplayPort Max Refresh Rates (SDR)

Looks like 7735HS isn't able to do 240hz refresh rate with 5120x1440p resolution but 7840HS can handle it. Can someone help verify if the documentation above is wrong and 7735hs does indeed support 240hz for my use case?
