Question Issues Running Certain Games on TV Through HDMI

[Typharius]

I've posted about this issue before but nobody could give me any solutions, I am at my wits end with it so I am posting again in the hope somebody new can help.

I'm using a laptop (ROG Strix G15) on my TV using a HDMI. 90% of the time everything is OK, but on a fair number of games I have this issue that occurs. I will start a game, and the TV screen either goes blank, or the game crashes with some sort of fatal error sometimes D3D related etc. If it just goes blank, I have unplugged the HDMI and low and behold it is working fine on the laptop. If it crashes, I have reloaded the game without the HDMI and it works fine on the laptop. Sometimes this issue will cause the laptop to restart or completely hang.

Some games I have a related (I think) issue where any resolution EXCEPT my laptops native resolution will crash the game, and others, anything higher than native crashes them....

If I set the laptop to duplicate display it tends to work fine as well, but I find it incredibly distracting having the second screen in my peripheral vision - This option also prevents me from accessing HDR so it really isn't a fix.

What is going on here and how can I fix it?

To add to this, on games that crash when HDMI is in, if I use the config to set the resolution to my TV native res of 3840x2160 - they run fine. Try to put them to laptop native of 2560x1440 they crash immediately. The games that are crashing also don't seem to accept HDR correctly.

I stress again, most games work fine, even brand new ones, older ones etc. But a good few have this critical issue and it's really bad.

Seems like the pc is conflicting with the 2 native resolutions on some games (individual games interacting with Windows 11 differently?)

I've spent 14 straight hours posting across multiple forums, scouring Google, just can't find any solution.

I've given up, I'm selling it.

Never bother with gaming laptops is my advice. Inferior in every way to desktops.
