HDTV, why make tv with resolution of 1366x768 when content is 720p...why is there a mismatch between 720 vs768
Also, how can you make sure the tv you choose will display good stuff in both 720p and 1080i.is it less risky to get a tv with a higher resolution like 19??x1080 ?
thank you
Answer:
I know it sounds silly that the TV industry created 1920x1080 TVs for 1080p content, but creates 1366x768 for 720p content. It doesn't make any sense.
Mystery solved! LCD technology originally were used for laptop screens, which came in native resolution of 1024x768 and 1280x768. Also, 14" and 15" LCD desktop monitors came in 1024x768.
My point is that LCD manufacturers just ported the 1024x768 to a 16:9 resolution, which is 1366x768 to LCD TVs. Basically, it was a shortcut decision made by the LCD industry.
You do have a point, in that video content looks best when the video resolution matches the TV resolution because no scaling is required. Will a 720p image look horrible on a 768p TV? Absolutely not. I have a 768p plasma and it looks great. The bottom line is that 1366x768 is a 16:9 aspect ratio resolution and so is 720p. It will look fine.
Significant scaling is bad, but minor scaling is unnoticeable. Displaying 720p on a 1080p TV or 480p on a 720p TV will look bad.
You would only want a 1080p TV, if you are planning on displaying mostly 1080p content. If you are not, then stick with a 720p TV. Since only BluRay, HD-DVD, Xbox 360, PS3 and computers can display at 1080p, then it is IMO a waste to get a 1080p at this time. All TV stations display in 720p or 1080i.
The content need not have the same number of lines as the signal. The TV contains enough internal processing power to deal with the various specified signals.
