Resolution Problems

I have an HTPC and i sit pretty far from the screen so I need to have a resolution of 1280x720 to be able to see everything properly while in windows, when I go into other games and fullscreen programs it switches automatically to 1920x1080 but retroarch does not. If I launch it in 1280x720 it works but the screen blinks, works fine if i set to 1920x1080.

Is there an easy way to solve this?

If you set the video_fullscreen_x/y settings in your cfg, it should try to use that resolution if a compatible modeline is available. It should look like this: video_fullscreen_x = “1920” video_fullscreen_y = “1080”

A better solution may be to change your DPI in Windows to be readable at 1080p. That is a per-user setting, though.
