I dun think anything was mentioned in the manual......maybe i try calling Sharp tomorrow. Tonight I'll play some action movie DVDs and switch on the split screen comparison thingy. Hmm..is our DVDs 50hz or 60hz?? ASTRO is 60Hz as TV is PAL system in Malaysia...so no difference for ASTRO i suppose.
Another question, if my DVD player upscale, will the TV upscale again? I read this in wikipedia:
http://en.wikipedia.org/wiki/Video_scalerSo if like that it defeats the purpose of a DVD upscaler? Or the TV smart enough to realized the signal already been upscaled (say 1080i) and just read the signal as raw input without doing anything??

Our TV signals are 50Hz (PAL). DVD movies are mostly 60Hz (NTSC).
On your second question, If your LCD TV is 720P (which is the case of the A53M) then
1) if you select 1080i in your DVD player, your TV will scale it to 720P
2) if you select 720P in your DVD player, it will pass through untouched (720P).
3) if you select 480i or 480P in your DVD player, your TV will scale it to 720P.
The rule is whatever compatible signal you input to your LCD TV it will always be scaled to the native resolution.
btw, the purpose of a upscale DVD player is to upscale normal DVD (which is 480P) to 720P/1080i. Although your TV can also scale 480P to 720P , stand alone upscale player normally do the job better. That's why people buy good upscalers e.g Sony 76H, instead of letting the TV do the upscale from a normal (Non upscale) 480i/P DVD player.
