Glad the audio hack worked for you. Sorry the drivers are still giving you grief. I noticed a couple of registry entries in the .INF file which might help:
HKR,, Display1_DVIHotPlugWAFlag,%REG_DWORD%, 0 ; 1 - Enable and 0 - Disable
Could be that, though it says DVI, HDMI will detect your TV better. Beyond that:
HKR,, Display1_AddUnderscanPercentageHDMI,%REG_DWORD%, 0 ; 0 - default 7.5% under scan and OEM's can give under scan like 8,9 an 10 ..
You should be able to modify the latter to change your underscan default.
;Driver Display Priority in Descending Order
;HKR,, DisplayPriority,0x00000001, 0x08, 0x80, 0x01, 0x10, 0x04, 0x40, 0x02, 0x20
This is based on the following:
" Bit: 7 6 5 4 3 2 1 0
" LFP2 EFP2 TV2 CRT2 LFP EFP TV CRT "
Thus, the ordering listed is LFP, LFP2, CRT, CRT2, EFP, EFP2, TV, TV2. I'm thinking SDVO HDMI (which this is) would be TV or TV2 (the other will be SDVO S-video from the Prolink card), so putting 0x02 and 0x20 at the head of the list would try those first. But I'm making this up as I go along, so be careful.
The prior one might modify which display gets attempted by the drivers; perhaps if it attempts HDMI first it will work?
You shouldn't have to run the computer 24/7 to get it to work properly. I hope the Intel driver guys can resolve this for you.
