Unable to Maintain Output Resolution Settings on Launch #15685

Open nickkeane opened 1 year ago

First and foremost consider this:

Description

Unable to set a fixed resolution in RetroArch to 2560x1440 (Keeps defaulting to 2560x1600 on start).

Expected behavior

RetroArch should create a window/fullscreen window with the correct resolution setting, if changed in Video -> Output -> Screen Resolution. These settings should additionally (optionally) be maintained in the cfg.

Actual behavior

RetroArch sets the correct screen resolution when Video -> Output -> Screen Resolution is altered to something else. However, this setting is not maintained between runs of RetroArch. After closing and re-opening RetroArch, the Screen Res resets to the default. It's likely enumerating a default graphics mode every time it starts.

Steps to reproduce the bug

  1. Start RetroArch
  2. Go to Video -> Output -> Screen Resolution.
  3. Change Resolution to 2560x1440. Resolution is changed correctly. Save RetroArch.cfg.
  4. Exit RetroArch.
  5. Start RetroArch. Resolution used is 2560x1600. Setting is not maintained or applied.

I can confirm a big issue with RetroArch regarding this display resolution.. It only works if you leave the settings alone and accept your not going to fix it. Windows 11

Example. I wish to have display in 4k, however I want my games emulating in 1080p for performance. If I force retroarch and tinker flipping back and forth from window to full, and force 1920x1080 i can get it to stick once!!! ALso I tried changing my display settings to 1080p in windows, and the bugger flipped it back to 4k. The only way it to run in with a 1080p monitor... Sometimes automation is a killer!!! It keeps wanting max resolution or it doesn't fill the screen

If I set it 1920x1080 it will not change the screen resolution and fill the screen 2 different computers, 1 nvidia 1 AMD

I believe most people don't notice for 2 reasons a) they leave everything and accept 4k emulation b) many people don't have 4k tv's so its a non issue

I've tried -f command line / everything/ changing directx12 , gl everything... It's a glitch

I wish we had command line force 1920x1080p and it flips to that mode in fullscreen non window..

Any other emulator , NO ISSUE, I like RetroArch for ease but,,, it isn't working for me

UPDATE
**Can't take credit, but someone online discovered this for windows 10-11 -Change your scaling to 100% (DPI) in windows -TURN OFF window mode in retroarch - set the output resolution to desire and open in Fullscreen -before this I was getting a partial screen top left corner taking up the portion set in windows screen scaling -Now this completely sucks for 4k as everything will be tiny. -In my case as a media machine - it helps -Retroarch does absolutely have something wrong here... Every other program such as dolphin has no issues including OLD stella,

Turn off windowed full screen is correct.
