: Why are 768 and not 720 panels becoming the norm for small panels?

I was wondering why with HD content being either 1080 or 720 TV manufacturers almost always still choose to go with a 768 panel rather than 720 for screen less than 32 inches? I would think that the majority of users are hooking up via SDTV or HDTV and not VESA resolutions. It would be like having 1152 pixel panels instead of 1080 as we have now in larger screens.

I just did a check at FS and for 32" LCD panels I could not find a single native 720 unit.

Inertia? Remember also that panels are made for the world, not just North America and of course that the smaller ones are made for computers. Doesn't explain the 46" panel for example, but those are switching to 1080P. ;)

32" panels for computers must represent a pretty small market.

I found this on Wikipedia.
A common resolution used in HD Ready LCD TV panels is 1366 x 768 pixels instead of the ATSC Standard 1280 x 720 pixels. This is due to maximization of manufacturing yield and resolution of VGA, VRAM that comes with a 768 pixel format

From what I see and read, 30+ inch monitors for computers are gaining some ground recently, but as far as I am aware, the bulk of the better ones are coming in at native resolutions of 2560x1600 (the reason for the shift to HDCP on dual DVI from newer vid cards).

Doesn't really tie in to why 30+ LCD TVs are maintaining the x768 res.....

on my laptop the only chooses for format outputs is...

800x600-irrelevant
1024x768
1280x768
1360x768

if the tv was native 1280x720??? then that might be a more REAL ISSUE. i have heard 1080P tvs have had issues with scaling PC setups. no 100% sure. could be fixed now.

720/1080 tv content scales to the native resolution of the LCD TV panel 1366x768 since it is still a 16:9 format. but with PC content, its does not always look correct.

I can see why someone would get confused by this:
16/9 = 1.7777777777777777777777777777778
1280/720 = 1.7777777777777777777777777777778
1360/768 = 1.7708333333333333333333333333333
1365/768= 1.77734375
1366/768 = 1.7786458333333333333333333333333
1920x1080 = 1.7777777777777777777777777777778

guess its about the ball park figure of 1.77 ratio.
