My Samsung Sync Master 910r keeps flashing "not optimum mode Recommended Mode 1280*1024 60Hz" I have had other monitors connected to this PC and The other PC as well without this error message. How do I fix this? I can't even access my desktop to change the settings?

Hello. That message appears when the video signal from the computer exceeds the monitor's ability to display it. If the sync is set too high(i.e. max sync on the monitor is 60 Hertz at that resolution), you will get that message. Check the video settings in control panel--("appearance and themes" in XP), go to the "advanced" tab and look at the refresh rate. Most computer video cards are able to far exceed a monitor's display ability. Don't exceed 60 Hertz--check the users guide for specs--the lower resolutions can have higher refresh rates(useful in games) Sometimes, a little lower video quality can yield a big performance difference in the display because the screen can update itself faster. (I use a radio control flight simulator pgm that is heavy on video ability).---Hope I was of assistance!---Rick

SOURCE: Hi

Try to change the desktop display settings, see screenshots below, see if it works

Right click on your destop and go to properties > settings

1. Set your Screen resolution to 1280X1024
2. Then click advanced and go to Monitor and set the refresh rate to 60 Hertz.

Make sure you also set the refresh frequency to 60Hz as suggested. You don't specify what system are you using, but it can generally be found in advanced display preferences under Monitor.
