Monitor blank on high refresh rate (144)

Post by FCM »

Hello,

I am playing OpenTTD on an ASUS ROG XG27UQR 4k 144hz Freesync display and I have the following issue:

- playing with dual monitors activated (the 2nd is an LG 4k 60hz) i get an intermitten blank screen issue, once every 30s or so.

It happens only in OpenTTD, only if dual displays active, only when refresh rate in the game is anything above 60hz.

The graphics is a 3080 TI connected via display port, I don't think the system itself is an issue.

I've swapped cables, connections etc but the issue presists.

If I switch to single display mode, everything is fine for some reason.

Playing in Windows 10.

Any ideas welcome, thank you!

Try enabling or disabling hardware acceleration under the graphics settings.

I have actually looked deeper into this, it seems it is a bug / data limit for 4k 144hz via display port with DSC.

I have manually set refresh to 120hz and the issue no longer occurs.

I don't think OpenTTD is in any way at fault here.
