HDMI on SyncMaster 2333HD

I tought I had a resolution settings problem. Altough the videos looked nice, everithing else was blurry. The content didn't fit into the display area. I've tried all the settings on my TV, which I could think of. I've changed the video driver on my lapotop. No improvement. I felt like going crazy. Luckily I've found this thread: http://ubuntuforums.org/showthread.php?t=1103332

Thank you nimitch!

"I came across a setting in the Samsung TV under the INPUT menu. The function is EDIT NAME. The TV gives a list of names from TV, Camcorder, Game, to PC. To my complete surprise, not only does this set the 'name' for the HDMI input but also adjusts settings to 'match' the input signal with the 'input peripheral'. Setting it to PC causes a 1:1 mapping to occur and the TV to do a true pass through of the signal from the PC to the output display. (The screen even blanks out for a second while it adjusts to the PC 'mode'.)"
