Full Screen Doesn't Work Properly

[Aleron Ives]

If you want 1080p performance but with Dolphin's image filling the screen, set the IR to 3x (which is as close to 1920x1080 as GC resolutions go), and then set the display resolution to 2560x1440 so that Dolphin will stretch the image to fill the screen. If you set the display resolution to 1920x1080, you'll probably get windowboxing.

My IR is already 3X, I'm repeating myself over and over again at this stage. I get window boxing unless the game runs at 2560x1440. Dolphin should be able to run full screen at other resolutions, like every unbroken game under the sun.

I have no idea what's wrong with your setup. I run 720p games on my 1080p monitor and Dolphin nicely stretches it as it should. Also, we're all here in our free time and we don't get paid to do this -- your tone doesn't really encourage anyone here to help you out any further.

EDIT: And I actually still don't understand your setup. Sometimes your overall Windows resolution is 4k, sometimes it is not. I'm confused.

Remember that full screen resolution is not the same as internal resolution, so, in Dolphin, setting full screen resolution to 2560x1440 and IR at 3x should have exactly the same performance as 1920x1080 with 3x IR, unless there's something wrong with your computer...

Dolphin is not a PC game. Setting the resolution of a PC game determines how demanding it will be for the GPU, but that's what the IR does in Dolphin. The display resolution in Dolphin determines how you want the image to fit the display and is unrelated to performance. It just stretches the image. If you select 1920x1080, you're going to get windowboxing, because your monitor has more pixels than that. The image will fill the screen if you select 2560x1440, but the performance should be about the same as if you had selected 1920x1080, as Jhonn said. Changing the IR is what impacts performance and visual quality.

I know how IR works.

Anthe you running an Nvidia or ATI/AMD card? I'm never running 4k resolution. The native res of my monitor is 2560x1440.

Valid 4K Resolutions are:
DCI 4K (native resolution) 4096 × 2160
DCI 4K (CinemaScope cropped) 4096 × 1716
DCI 4K (flat cropped) 3996 × 2160

I run at 1920x1080. I was just explaining that changing to 2560x1440 regardless of dolphin settings still doesn't let me run at 1920x1080 while taking up the full screen real estate. I've said this in 10 different ways now. I'm positive this is a flaw in the way Dolphin deals with exclusive full screen mode, because when it's disabled via an alt tab it does fill up the screen.

I found a reasonable work-around by using window borderless full screen mode. The performance is fine in that mode so I'm considering this a bug that I may check into, but probably not since the work-around works fine for me.

To answer your question: I'm running an AMD A10 with 7570 APU (unfortunately). I've got nothing but trouble with it :')

Borderless fullscreen has more latency and you may miss some frames. That can break some graphical effects in some games and there's more details in progress report from july 2014. Below is an example:

Upgrading to Windows 10 seems to have solved my problem.
