HP DV7T display..

Recommended Posts


greetings to all - I'm wondering if I could ask all you guys for your advice - I have my DV7T i7 720 ATI mobility radeon HD 5650 working - full QE/QI and recognised correctly in system profiler but ONLY on an external vga monitor - LCD panel remains backlit but black.


Am I right in thinking this has to be a EDID issue - since the drivers obviously work on the vga is it just that the system doesn't understand the LCD panel?


Thanks - and apologies if this isn't the right place to ask.
