Biostar A780L3L - no DVI output :S

[crazylegs]

Hi all - so i'm doing a favour for a friend and have upgraded his system on a budget using:

- Biostar A780L3L motherboard (http://www.biostar.com.tw/app/en/mb/content.php?S_ID=495) basic but does all he needs.

- AMD Athlon II x2 250

- 4GB generic RAM

- used existing HDs / CD/DVD / PSU / Case.

Anyway, Win7 installed fine, upgraded drivers etc... all the time using the VGA output - no problems. Take it over to his place, where he uses a DVI connection to his monitor... no image on screen :S Could hear it posting, so i took it home. Plug into my VGA all is well, have been racking my brains and searching through BIOS options and unless i'm missing somethign really obvious can't tell why it wont output graphics over DVI :/

The only relevant BIOS option is for what appears to be a graphics priority list. But not an 'enable/disable' DVI output. Changing the 'priority' (there are only 4 preset options) seems to make no difference. I have got it setup so i can inter-change between a VGA + DVI connection, w/e i've tried so far VGA works but DVI does not.

Any suggestions are welcome!

Thanks in advance

Does it work with both plugged in? That might help figure out whats up.

Can you try to remotely control the system when using DVI (e.g. teamviewer)?

Just rigged up dual monitors and it will works using the DVI as a secondary output.

Can't for the life of me understand why it wont work with just DVI plugged in?

I haven't tried to remote access the machine, but with DVI plugged in i hear it make the POST success 'beep' but nothing appears on screen :S

Friend is planning on using dual monitors, so it should be fine as it is - if a little strange.

Hmm. Updated the BIOS to newest?
