Q:Why I need 1280X1024 resolution?
A:For CRT monitor, you can find more than one resolution at which you can get better display
quality, but for LCD monitor, one panel only have one resolution at you can get the best display
quality, other s are not so good, even you can say its no good, normally, 15” LCD monitor’s best
resolution and highest resolution is 1024X768, for 17” and 19”, its best and highest resolution is
1280X1024.
Q: What is the difference between LCD TV BOX and other such 640*480 level TV box (for an
example, TV box V for CRT)?
A: The key difference is our LCD TVBOX has a 9 bit input ADC and have a digital de-interlacer
inside our main chip, which improves the picture quality.
