Monitor turns black and with a not optimum mode pop-up

My kid played a teaching game required a lower resolution mode, after we turned the game off, monitor couldn't go back to its regular mode, but turned black with a floating pop-up showing: not optimum mode, recommend mode: 1280x 1024.
The monitor menu and auto adjustment are freezed. I tried to re-start my comuptor, but it showed the same pop-up.

How should I do

Monitor work well on starting, but entering into any games, its turn black and the power light is on. Computer has nothing problems with other monitors.

The games try to start a display mode (resolution) with which the monitor is not compatible. Some monitors are very tolerant and try to display whatever they are hit with, even if the picture is poor, at least you have an option to change the resolution to a different one. Some however are very picky and just go into standby if they are fed with signal that's not optimum.

You have to find out which display modes your monitor does support and then try and configure the games to use one of those supported resolutions. If you can borrow a more tolerant monitor you could attach it temporarily, open each game and adjust the configuration to satisfy your whimsical monitor, and then reconnect it.

"Not Optimum Mode","Recommanded Mode 1280

FIXED : Before you start your legacy game, software where the "Recommanded Mode 1280 x 1024 60Hz" keeps showing, change your display FROM VIDEO CARD DISPLAY control application to 1024x768 or your choice.

My Syncmaster 2233 had same problem of "Not optimum mode" box coming on whenever I started any old game like Age of Empires etc. It got fixed by selecting FROM DISPLAY CARD DRIVER CONTROL UTILITY's (mine from Catalyst Control Center) >Set desktop area to > 1024 x 768 in my case BEFORE STARTING old application/game. Switch back to your normal resolution after you are done with this application.

Hope this helps.

Hi,i want to play woflenstein game and wen i launch i hear the sound but i don't see anything its says"Not Optimum MOde Recommended Mode 1280 x 1024 60 Hz" why i should do? ty for any help...

Your game is trying to feed the video signal to the monitor that is too high for the monitor to display, you need to set your PC video resolution to 1280 x 1024 @60Hz. If the game needs higher than that, then you need a better monitor. Does your game allow you to lower the video resolution?

Display Problem

video card may not be capable of that resolution and color depth, check your video cards max resolution and color depth.
I have several lcd monitors that are 1280x 1024 and they do not need drivers to work. the video card must be capable of generating that resolution.

Samsung SyncMaster 17" LCD Blacks out

If you have a second monitor, you could use your computer until the monitor goes black... then plug in a replacement monitor. My guess is that one will display black too...

My gut feeling is that your VGA card is on the fritz... I'm not convinced it's your monitor. Do you have a replacement VGA card you can try? I'll bet that'll take care of the problem.
