Hi I've got a Samsung TFT monitor -Syncmaster 710V - that gives an error message.Message reads: Not optimum mode Recommended Mode: 1280 x 1024 60Hz This screen is impossible to get rid of. Anyone know the solution? I would be very grateful for a helping hand! Cheers.

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.
   

Hello

Here is something you can try:

Check your LCD's OSD setup menu (On Screen Display = OSD).
Mine used to give similar message whenever any program was not set to LCD max resolution. It is just a reminder by manufacturer as LCD diplay works best in its native resolution (max res). Any lower resolution and screen is 'scaled' in size to fill screen area, giving less quality picture.
Drivers allow (via CCC) to turn off scaling. This way screen image gets smaller as resolution lowered but text stays sharp and in focus. So as an example on 20" screen set to 800x600 with scaling off you get a big black border all around the screen display - but the image is sharp. (Not sure why you would want to do this but thats what happens.
Unfortunately this CCC feature stopped working in 5.13 for me.

Anyway solution for me was to turn off warning in OSD.

Realy hope this can be of help.

Kind regards
Andrea

Well, do what it says - go to Display Properties in Control Panel and set your display resolution to the recommended settings. You will get a better picture quality too.
