Sorry if this has been answered before.

I have a DELL U2713HM 2560x1440 LCD monitor. I'm currently running the Mister at 1920x1080 (mode 8). Everything is fine but I noticed there is a 1920x1440 (mode 12). But if I try to use that I get a error on the LCD telling mode to use a mode like 1920x1080. No idea why this happens, but since this is NOT in the list of Windows display resolutions; I assume it's not possible. Question, is 2560x1440 not a doable resolution? Thanks

2560x1440 is a odd ball resolution that don't have clearly defined standards so many PC Monitors and HD TVs that are at 1440p or 4K don't like 1440p input. Example my Samsung 8 Series 4K TV doesn't like 1440p despite being 4k

Not all monitors or TVs support all resolutions
My LG OLED65E6 can accept anything between 240p-1200p, but it can't accept anything beyond that other than 2160p.

1920x1440 is already overclocking the Mister's scaler/hdmi chip, 2560x1440 is just too high a pixel clock.

You might give 1920x1200 a try with a custom video mode.

Thanks all for the info. I'll leave it as it is. No point breaking what isn't broken
