Resolution problem

[leonsamar]

I cant change my resolution to 1440p in fullscreen mode. The game only have 2694x831

Unreal Engine has a DPI scaling bug that causes this.

You can run your desktop at 100% DPI scale and it will help.

You can also set DPI scaling compatibility mode

-> I cannot tell you the precise setting name, it depends on Windows version.

On my TV Fullscreen and Borderless doesn't give any option but one (greyed out) and it's slightly bigger than the typical 3840x2160.

But using Windowed did have 3840. Dunno if it would be the same for monitors (4k tv's supposedly have my specific issue mostly?) but who knows. Could try it and see, anyway.

4096x2160

That's a different issue you're having. It's caused by Unreal Engine using the largest reported resolution rather than the native or even active resolution. In borderless mode, you can ignore whatever stupid number the game reports because it actually does use the correct resolution.

However, borderless mode unmodified comes with 2 frames of extra input latency that you do not want. I would suggest using Special K for proper borderless performance, or running the game in Fullscreen mode. You need to remove the 4096x2160 resolution from your EDID, or use Special K and limit resolution to 3840x2160 for fullscreen mode to work correctly.

I saw another thread where you mentioned that.

I switched to their "Windowed" mode (which on the TV is the only 3840 option) and have seen/felt no difference re: latency/performance over either Full Screen or Borderless. Maybe it's just my rig is good enough to not notice, or my eyeballs/brain just don't notice, dunno. At any rate there "feels" like no impedance, thus I don't really care.

In this case their Windowed has no actual "border" around it either, so visually it just looks/acts like Borderless.

Full Screen also doesn't fit/size to the LG OLED TV screen properly because of the weird resolution (while Borderless and Windowed does), so stuff like the R1 prompt for skits in the corner is only half visible, which I don't want either.

Yeah, that problem affects a large number of games. You should either use Special K or CRU and remove 4096x2160 from your display's EDID.

Off the top of my head, most of Ubisoft's games, Tomb Raider, and various Unreal Engine 4 games take the highest reported resolution in your EDID and consider that your display's native aspect ratio.

4096x2160 is a cinema resolution, it is 256:135.

Because the game thinks your native aspect ratio is 256:135 and the display only has one resolution that is 256:135, this becomes the only fullscreen resolution choice you have.

Tl;Dr:

Gotta get rid of 4096x2160, it breaks many games :)
