Not Optimum Mode, Recommended Mode 1366x768 60Hz. HOW TO FIX?

Hey guys,

When I boot up my PC, after showing the windows logo, the monitor goes black and a box saying "Not Optimum Mode, Recommended More 1366x768 60Hz" pops up. I have a Samsung SyncMaster S19B150 monitor and I'm running Windows 10 on a i7 860 and a GTX 750ti 2 GB card. How do i fix it?

What kind of cable are you using? Do you get into windows as normal after the message or does it just stay black?

Don't ask to ask, just ask... please聽馃え

I'm using a VGA cable. No, the desktop doesnt come on the monitor. After the windows logo, instead of opening the deskptop screen, the monitor becomes black and stays black apart from the box that says , "Not optimum mode, Recommended mode 1366x768 60Hz".

1366x768@60 is very close to the max throughput of a VGA cable in most cases. Not to be patronising, but are you trying to run 1080p over VGA ? it is a thing, technically, but practically, just no

No I'm not trying to run 1080p. Although in my GPU overclocking software (ASUS GPU Tweak) , there was an option to set monitor refresh rate. Just to see what happens, I set it to 144Hz. After that screen went black. Maybe thats the issue?

The cable might be damaged, using a digital cable (dvi) or simply a different one could show whether it is the problem or not. If you have access to a different monitor, try using that.

That's not true, VGA can do up to 2048x1536@85hz depending on the cable and the monitor. 1366x768@60hz should not give any sort of problem. I've run 1080p monitors on vga multiple times, no problem.

Neither is true, because MOST vga cables and monitors have no problem running the advertised resolution, both in theory AND in practice. Unless, of course, either is defective - but that wasn't among your "qualifiers", was it? I suggest you stop trying to defend a false statement on semantics.
