I have all my electrical equipment hooked up to 1 HDTV, that is sky, ps3 and computer. Today i noticed that when i change the input mode while booting my computer there is an option next to RGB. This option is either PC or DTV depending on which one i select, what is this? and also which is better?
The two choices are PC Personal Computer or DTV Digital TV. Depending on what you're doing will determine the mode of operation. When in TV mode you use the TV controls to set the width and aspect ration of the display. When you're using the PC the graphics card will normally set the width and aspect ration. Ever notice that when you change resolution on a normal PC monitor that 640X480 uses just as much screen as when it's set to 1072X768. The graphics card adjusts the size. DTV mode will have the internal controls in your TV controlling the size and PC will have the graphics card in the PC controlling it. As I'm writing this another possibility came to mind. You may have an ATSC tuner (digital tuner) built into your HDTV. The TV may simply be asking you which source you want it to look at. In other words do you want to continue watching TV using the internal tuner or switch to looking at the PC information that is now available. Your best bet is to pick up the owners manual and read the section that tells you about hooking up your computer to the monitor. I'm sure that will explain what your asking for.
