Avoid the 1932 - there are lots of people having problems with this Panel. There is a recent thread here in TE about this. Some panels are now being supplied without the DVI cable - check for this as a cable costs around 600/-
Dont know about 19" Panels. I use a Viewsonic 22" 2245 and it is great for movies. But if I had to buy a 22" Panel again it would be the LG, Dell, Samsung - in this order. Wait for some other TE member to give an answer about the 19" panels - meanwhile check the Dell 19" panel from Raghu's GO, this will probably be the BEST one to get.
Possibly the LG 19" panels are not that great - but I have read very good reports of the LG 22" and 24" panels. Dont forget one thing - Viewsonics A.S.S. sux big time in India !!! One of the worst from what I have read in the forums.
