Game keeps defaulting to 1080p.

This problem has existed since 2.x patches I believe, but I'm reporting it now after being fed up with it for so long.

I have a 1920x1200 monitor, which is uncommon or not manufactured these days but the games still support this resolution. PoE works just fine on this resolution, but whenever I reboot the client, it ALWAYS resets to 1080p (1920x1080) resolution AND resets to windowed mode.

Everytime I restart the game, I have to manually set both things again. Quite odd that whenever it downloads a patch, it doesn't reset those things but when I restart the client with no patch pending, it always resets.

Some info about my setup:
Using this website's client (not Steam version)
DX11 mode, Win 10 Pro
1920x1200, 60Hz

Unfortunately I do not have a 1920x1200 monitor myself to test with.

The first thing that comes to mind is that this could be either a problem with the resolution, or an inability for the game to make permanent changes to its own files. Path of Exile stores its settings in the production_Config file in the Documents/My Games/Path of Exile directory.

The free programs Notepad++ and Brackets are good text editors which will better understand the file’s formatting than Notepad would. I’d suggest opening it in one of those, scrolling down to the [DISPLAY] section, and checking which resolution it is set to. If it’s 1080, try manually changing it to 1200 and saving the file. Either this will fix it, or we’ll know more about the problem.

Just checked the production_Config file and this is what it was set to:

resolution_height=1103
resolution_width=1902

That's an odd resolution. I changed it to 1920x1200 and fullscreen=true. Saved the changes! But once I launched the game, again it went back to 1902x1103.

so I guess this counts as a bug, the game supports 1920x1200 but fails to recognize it on boot. People aren't reporting it because hardly anyone uses 1920x1200 monitors these days.

Now I wonder if GGG would care to fix this. Oh well.
