Hi Guys, could you know anyone that can help with my blank screen problem? I have an hp tx 2500 tablet running on windows 7. i guess the problem started the first time i connected it to tv via VGA. Days later, the screen would go blank on start up and would have to use the F8 and F10 keys to restore it. I thought the BIOS was outdated so I updated from F.05 to F.OF. When I change the resolution from High performance to Balanced Performance - or vv - the screen goes blank most of the time. Switching from one user to the next also brings up the same issue. Sometimes I have to do 10 restarts to see what I am doing. I dont think its an ATI radeon problem cause i just got an update from manufacturer. I suspect there is a conflict that was created the first time I connected it to an external display as it hasnt been behaving as it should since then. Many thanks in adv.
