rave's dvi aint working. this solution dint work for him. i had told him bout this a month back. there are some other solutions also. its some problem which many ppl are facing who are on nvidia.
yes, Viewsonic India gives full warranty support here. and be carefull with Nvidia cards and DVi. I have to reprogram the EDID(firmware) from scratch and flash it to get my monitor working again(thanks to stormy and DarkNight for helping out here) now i believe the DVi should be working but i dont have an DVi port to test it on as of now, will check for sure when i get my gfx card in a couple of days...
Rio, if you can, backup and save your edid using that viewsonic edid editeer available on their site.
