LCD TV 1680x1050?

[wulf109]

I notice that most 22" LCD TV's are 1680x1050 which is 16:10 not 16:9. How do they display the picture? Do they stretch the height of 16:9 and 4:3 pictures? What do they do with 2.35:1 ?

A 22" 1680x1080 LCD panel is usually used as a VESA spec computer monitor. LCD-TV panels are usually 1366x768 (square pixel 16:9) at 26" or above. Larger screens may use square pixel 1920x1080. When 16:10 displays are used for TV use, the designer needs to decide whether normal 16:9 TV will show as letterbox, be side cropped, or be displayed as tallish 16:10.

4:3 should be scaled to 1400x1050 (or overscanned). This would produce narrower sidebars vs. a 16:9 display. 2.35:1 would have less display height compared to a 16:9 display.

You won't find this in specs. You need to demo the TV.


PS: Low end LCD-TV sets that use computer monitor LCD panels are less likely to produce solid blacks or TV gamma response. You should demo in normal room lighting conditions to evaluate overall contrast and ability to make a true black. Larger display panels are optimized for TV use.

I have a 19" 1440x900 LCD TV (16x10). I has the option to display a 16:9 picture letterboxed (small black bars top and bottom), stretched to fill the screen (distorting the picture), or zoomed slightly to fill the screen (cropping off the left and right edges).
