SAMSUNG SYNCMASTER 226BW WHEN TURNING ON MONITOR, IT SHOWS BLACK AND WHITE LINES THEN IT SHOWES A BOX THAT SAYS "NOT OPTIMUM MODE, RECOMMENDED MODE 1680 x1050 60HZ " AND IT IS STUCK ON THIS SCREEN

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.

then restart and then install the driver again the driver is crrupted than install the right driver problem could be solved

Hi Guys.
I have had this problem and after a bit of searching found that it is a known problem.
Give Samsung a ring and if it's in warranty they will replace it

Does it show a picture in safe mode? If it does you might want to install drivers specific to the Monitor if you can find them.
