I have an ATI card. If I go into the "Catalyst Control Center", then select the monitor (DTV (DVI)), go to Attributes, there is an option for "Image Scaling". If you select "Maintain aspect ratio", it should do what you want.
You might want to add what OS you are using, and what graphics card you have. Good luck!
I have a PC hooked up through the analog VGA port to the Samsung, and I want the TV to automatically change it's own resolution to whatever resolution is on the PC.
The problem is that the TV only has two display settings - 4:3 and 16:9 - and keeps the aspect ratio no matter what resolution is on the PC. I want to be able to watch movies on 16:9 and play video games on 4:3 without having to adjust the remote.
For instance, the desktop display is 1360 x 768 (about 16:9), which looks fine for widescreen movies. If I boot up MAME, it switches the PC resolution to like 800 x 600, and the TV stretches the display to 16:9. This doesn't make any sense when dealing with a computer, since the resolution is given to the TV (it shows at the top left of the screen).
How do I make the TV just run whatever resolution I got on the PC and not try to force aspect ratio?
