I just bought a new notebook HP COMPAQ CQ58-D69SG NOTEBOOK 15.6 (details below). and installed ubuntu 12.04 when i connect it to my tv with HDMI when it is already booted the screen apears, and seems fine, except that the tv gets recognized as 32", although it is a 42" but when i want to boot while the HDMI is connected I only see a blank screen. (not even "press esc to bios), and the tv seems to feel an input, because it switches to HDMI 720p. the funny thing is that I tried it with a different TV (however more like a monitor) everything worked fine... I have searched a lot in the internet, but did nor find a solution. there were a few posts about repository drivers wich i have not tried yet, because i am not sure if its good...
I hope somebody can help me solve this issue
