I seem to have created quite a tangent with mention of my "720p class" bedroom TV that has a native resolution of 768p and thinking next time I should go with either a real 720p or a 1080p TV.
Many "720p" TVs are really 768p, including the one I had purchased three years ago. The TV can accept 480, 720p, 1080i & 1080p, but there is no HDMI standard resolution of 768p, so every signal fed the 768p TV will be rescaled.
My thinking is this: every resolution I can feed the 768p TV requires the TV to rescale, so if I am feeding the TV from a source that will rescale the image (such as a Roku digital video player, which takes whatever resolution it receives and scales it to the resolution it is configured to output, or a Blu-ray player with its factory defaults if used to play a DVD), then the image will suffer from double-rescaling, which tends to reduce the sharpness of the image.
At the time the 32-in 768p TV was a decent tradeoff between costs, resolution and size, and right now the only inputs to it aren't doing any rescaling (the DVR is set to "NATIVE" to feed the TV the same video resolution as the channel it is receiving, but with the advanced setting to deinterlace 480; and the VCR/DVD combo unit feeds the TV either composite 480i or component 480i, the native resolution of VHS tapes or DVDs), so only the TV is rescaling what is thrown at it to the screen's 768p.
But if I were to add a Roku 3 to the 768p TV, there would be potential double-rescaling, especially for 480p content (such as many older TV shows) that would lose some of its sharpness.
And, likewise, a Blu-ray player with its factory settings will generally rescale a DVD (480i) to 1080p unless the player has an advanced setting that allows me to tell it to pass either 480p or 480i to the TV when playing a 480 source and I make that adjustment.
On the other hand, if I had a real 720p or a real 1080p native resolution TV, then I could configure a Roku 3 to match the TV's native resolution and then the only rescaling would be the Roku rescaling to the TV's native resolution where needed, and a Blu-ray player could likewise be configured to output the TV's native resolution so DVDs from Netflix or pre-Blu-ray titles I own would likewise be rescaled to the TV's native resolution.
Generally, though, when I want to watch Netflix streams or Netflix discs, I do it on the other TV that is native 1080p and has overscan turned off, and I can feed that TV at the TV's native resolution.
If I were in the market for a 32-in TV today, I would be much more inclined to look for a native 1080p TV.
My very humble setup:
