As for the model number of the " best reviewed HDTV" , if you can' t remember the model numbers, how do you know it isn' t the one I own?
As for the 720p to 768 scaling, I' ll explain this like an adult, let' s see if you respond with something other than the child-like comments you like to throw out.
I made some quick images for everyone to look at. The images themselves aren' t of anything special, just a bunch of tiled screens from an emulator because I wanted to start from an uncompressed pixel for pixel image and not some crappy image (like a JPEG) to best represent my point.

Notice how the 768 version is noticeably more blurry. If it looks fine to you, then that' s great! But to me it is not acceptable. Different TVs use different methods of scaling the image, and they all result in differing quality.

This image is sized 200% to better illustrate my points. The original 1:1 is a small sample taken from the 1280x720 image, and the rest were taken from the 1365x768 image upscaled in various different ways. Observe.
The
original 1:1 is pixel perfect in every way. No distortion anywhere. Everything is represented exactly as the source is, pixel for pixel.
Bicubic resampling is the best way to scale (which is also what the large 1365x768 link above used), but it still results in some loss of sharpness and also introduces some artifacts as a result of the scaling. Notice the new grey lines above the score box that are not in the original image.
Nearest Neighbor doesn' t seem to lose anything in sharpness, but you do get new pixels that don' t belong. Look at the round, green orb thingy in the lower left. It has quite a few new big, black pixels at various points around it that is not in the original source material. As the screen moves or scrolls, these extra nastified pixels will become very apparent. I don' t think too many if any TVs use this type of scaling.
Bilinear resampling is a pretty bad form of scaling as well. It has all of the same stuff introduced to the screen as bicubic, but it also adds and extra layer of blur. Many TVs do this because it is very quick and easy. And speed is important when dealing with common lag time found in LCDs and DLPs.
Overscan is irrelevant as the image is still being scaled by 3%. If the image was being displayed at 1280x720 and the rest of the pixels were beyond the border of the screen, then it is not being scaled at all. But most LCD, DLP and plasma TVs have little to no overscan these days.
Now again, this may all be fine for you, and if it is, that' s great! I personally don' t like it. Just because somebody disagrees with you doesn' t mean they are a dumb fuck who can' t keep a job and is a complete loser. Only someone with the inability to express his viewpoints would say stuff like that. I am prepared for your angry childish insults and fanboy-ish remarks. Or you could try talking like an adult to express your points, but somehow I don' t think you are capable of doing that.
