why is there 16:10? Is 16:9 not good enough??

I thought the 4:3 and 16:9 issue was already settled. Why then are some LCD monitors intended for PC use 16:10 as in 1440x900 or 1680x1050?? Try as I might I can't seem to find out where 16:10 originated . Did a committee create it? Why not just stick to 16:9? The difference in 16:9 & 16:10 is obvious when I connect my HDMI equipped DVD player to my 1440x900 monitor; of course there is slight vertical stretching.

16:9 resulted for psychological research in Japan and MIT. Binary math didn't enter into the decision since Japan's first system was analog and the American ATSC system assumed a "rubber sheet" scaled display that can handle many resolutions. ATSC referenced the work done for ITU-REC-601 (later MPeg2 and DVD) that led to the 16:9 wide format definition.

Separately and in isolation the computer display people continue to generate "VESA" resolutions based on H&V binary addressing so frame buffer memory and plasma/LCD/etc. pixel addressing match without scaling at "native resolution".

TV and PC use different pixels, non-square vs square and different resolutions

you can buy a 17" or even 15" monitor with 2048 horiz pixel res

put you won't find a TV with that rating

However there are a number of low budget LCD TVs that do run at 1440 x 900 or 1680 x 1050 16:10 AR. Basically just low end monitors with a cheap digital tuner card thrown in. 500:1 contrast ratio as well. Damned ugly.

Computer monitor engineers and TV display engineers don't talk to each other.

There were two resolution points where 16:9 was a forced match (not binary beautiful but square pixels) and these were added to the computer spec.
