Sony VAIO lcd upgrade possible?

sorry if there has been a thread for this but i didnt see it from searching. i have a sony vaio model vpceb490x with a lcd resolution 1366x768, i bought it with the upgraded ati 5650 video card. i was wondering if it was possible to buy a plug n play replacement lcd with a res of 1920x1080. i bought a full hd lcd but after plugging it in the lcd backlight lights up but no pictures, so i reinstalled the old lcd and it works normally. is there a setting i need to have done for the sony to see a new lcd screen? ty ahead of time for any help.

 

What screen did you buy and from where? Could you post a link?

 

i bought it from 247laptoplcd.com. SONY VAIO VPCEB490X LAPTOP LCD PANEL 15.6" GLOSSY Full-HD
but theres a bunch of these places selling the new higher res lcds now. they all tell you they dont recommend upgrading. the one they sent me was a from lg. everything plugs right up.

 

They say "or you can contact us for help." Did you try ask them about extra steps/parts for the diffferent resolution screen?

 

they dont offer support or advise to change lcd resolution at all. just want to see if any1 has done this b4 with success.
