🖥️ Triple screen setup not possible with NVIDIA Surround (3×2K monitors — looking for alternative solution)

[JoshLeGrenat]

Hello everyone,

I’m trying to set up a triple screen layout in Euro Truck Simulator 2, but I can’t use NVIDIA Surround because my monitors are not identical.

I have three 2K monitors (2560×1440): two identical ones running at 165 Hz, and a third one that’s also 2K but originally 240 Hz. I manually set that third monitor to 165 Hz so all three are matching.

Even though all three monitors now have the same resolution and refresh rate (2560×1440 @ 165 Hz), NVIDIA Surround will only work in Full HD (1920×1080). It refuses to run in 2K across all screens, probably because one of the monitors is a different model.

I’ve already searched online, including on Reddit and here on the forum, but I haven’t found a clear answer to this specific case. I’m sorry if this topic already exists.

Has anyone managed to run a triple monitor setup in ETS2 without using NVIDIA Surround — for example, through a config file edit, a custom resolution, or a manual parameter tweak? Something like how iRacing lets you define the resolution directly in the game files.

Any help would be really appreciated.
Thanks in advance

There's an alternative way without Nvidia Surround or AMD Eyefinity for triplescreen.

1.) Make sure, your center screen is set to primary in Windows settings

2.) Change following lines in config.cfg

Code: Select all

uset r_mode_height "1440"
uset r_mode_width "7680"
uset r_windowed_borderless "1"
uset r_fullscreen "0"

3.) Start the game. You should now see a small triple screen window on your center screen like this:

4.) Open developer console and enter following command:

Code: Select all

g_mode 7680 1440 60 0

where the first 2 values are your horizontal and vertical resolution, 60 is refresh rate and 0 forces a borderless window over all 3 screens.
