"Native Resolution" concerns.

10-23-2007, 09:12 PM
I have a 36" Sony HDTV (CRT) and all programming looks fine - ie: no stretching or compression, as it has no "Native Resolution" and shows each program in it's own resolution automatically.

Most Plasma and LCD TV's that I have seen in use in homes show signs of that malady since they do have a "Native Resolution" which forces all programming into that geometry.

Are these flat panel users missing something? The problem is obvious to me, but they seem to be gleefully oblivious to the problem. Is there an easy fix or does the zoom have to be adjusted for each program with a different aspect ratio. As we all know there are a lot more aspect ratios out there than just 4:3 and 16:9!

It's true that although your CRT *tube* itself has no "native resolution" (although it does have inherent resolution limits imposed by the fineness of the tube pitch as defined by the phosphor dots and aperture grille), the digital electronics in the set automatically scale any incoming signal to 1920 x 1080.

All fixed-pixel displays also scale any input to their native resolution. There should be no distortion in the image proportions, though. If you see stretching or compression, it's because the user has the wrong screen mode selected, or they prefer to watch 4:3 program content stretched to fill a 16:9 screen, rather than watching it with side bars.
