Can’t get Raspberry Pi4 to fill the screen

[Bloodta]

I have a Dell 2007fpb monitor connected to my raspberry pi4 via micro Hdmi to dvi-d. I can’t get it to fill the screen no matter what I do. I’ve tried un commenting disable overscan, I’ve tried manually entering the overscan with negative numbers, I’ve tried setting the resolution in the config.txt file. The monitor has a 1:1 setting but it’s set to fill, and it won’t let me change it (it’s grayed out). I’ve googled and tried every suggestion that I’ve come across. The opening video has bars at top and bottom, but the game selection screen fills the entire screen. When i select a game the bars come back.

By "game selection screen" you mean Emulation Station?

What it sounds like is that overs and, etc is fine, but you need to adjust settings for Retroarch...

Yes, emulation station.

Just another one of those reasons I hate Pi's. You have to configure like 20 different things to make it look right, then you try and help someone and they try explaining it with a "this one screen that I see here" and your like, great, is it retroarch, an emulator, emulation station, did you set them all up and yadda yadda.. Do a PC, just install attract mode and mame, set your paths, hide the OS and your good. No flipping and streching just change to landscape or portrait mode and the emulator and front end do the rest.
