While trying to play Last Epoch, every time I would launch that game, it would launch on the wrong monitor. After spending a lot of time reading, trying to resolve the issue, I finally figured it out. I am not sure how many people will have this issue, but if it even helps one person, then me taking the time to post this was worth it.
When I would load the game, regardless of the setting in Last Epoch, it would always pick the wrong monitor (I am unsure if the monitor selection in the game doesn’t work, or if it just doesn’t work with my configuration).
I was able to use WIN+SHIFT+ARROW KEY, but the problem is, when you do that in Last Epoch, it only has the original monitors specifications. For example: The monitor it kept forcing my game to launch on was a 1080p, so when I would WIN+SHIFT+ARROW KEY to my 4k monitor, the highest resolution would be 1080p, so it was important for me to launch the game on the correct monitor.
The reason I found for this was, I am technically running two graphics cards. While my secondary graphics card is more of an peripheral extender, as my 4090 is maxed out (I run 6 displays) it still counts as a ‘Display Adapter’. For whatever reason, Last Epoch would read the external graphics first, thus always forcing the game to launch on the primary monitor attached to that device.
I was unplugging the external graphics device, launching the game, then plugging it back in. Then I would go into device manager, disable the device, launch the game, then re-enable the device. I also would try not to close the game, I would just leave it running in the background when I wasn’t playing it, lol. Obviously none of these are ideal solutions.
The Solution! You need to go into your registry to resolve this.
Computer\HKEY_CURRENT_USER\Software\Microsoft\DirectX\UserGpuPreferences
Look for Last Epoch.exe
GpuPreference=1;AutoHDREnable=2097;
Mine was ‘GpuPreference=2;AutoHDREnable=2097;’ Once I changed the GPU Preference from ‘2’ to ‘1’ my issue went away.
Hope this helps someone!
This is the USB to HDMI adapter I am using.
