    Hi everyone,

    I'm about to purchase a 50 inch Samsung DLP TV with DVI. From my research I have learned that for ultimate picture quality playing a DVD with your video card set to 1280x720 is the way to go. There are applications written for Windows PCs to allow this. Does anyone know if there is anything for the Mac that will work?

    I have a Dual 2.0 Ghz G5 with the stock video card.

    I'd try plugging it in and selecting Detect Displays...I think that would detect your tv's native resolution.

    You may want to check Version Tracker or MacUpdate for some form of Display software.

    a quick search on MacUpdate under "display resolution" revealed DisplayConfigX .96 which seems to be exactly what you need.

    my thoughts exactly.

    The resolution of a DVD is only 720x480 (NTSC) or 720x576 (PAL), so I'm not sure why that resolution of 1280x720 would make any difference :confused: The only time it would make a difference is if you actually wanted to use the screen as a monitor for web browsing etc.

    Actually 1280x720 is an optimal resolution for DVD playback in a certain case. A nice DVD player outputs 480p (progressive scan), If your HD Monitor does 480p that is nice, but many HD sets actually have a preferred resolution. I know a Samsung DLP I've been looking at converts everything to 720p when it displays it. We all see 3:2pulldown listed in HD feature sets, this is where that comes into play. With a native DVD resolution of 480p multiply times 3/2 and you a perfect 720 matching the native resolution of the HD display.

    However, in the case of the poster he actually not take advantage of this since his computer will be scaling the image. My recommendation to the original poster is that if his computer cannot output 1280x720, he should not attempt the next highest resolution, but rather take it down to 480 lines of vertical resolution as to take advantage of the optimal 3:2 pulldown ratio of the TV set.

    However, I would also mention that if it were me, I'd go ahead and spend the extra bucks on a nice DVD player to play DVD's and use take the G5 out of the entertainment center...
