Anybody know of any display issues with this motherboard/gfx card/tv? i can sometime get the display to work but most of the time after being shutdown the display won't come back on.

The computer is booting fine into windows as the VFD display on the case shows system specs/temps etc and this only works when windows has booted to desktop.

I have conflicting stories of it being the tv not recognising that the pc is not connected and it needs a firmware upgrade (EDID) but i have also heard that its to do with the DVI out on the gfx card not sending the signel to the tv.

I have tried the computer on a pc monitor with a vga cable but still no picture and i can't try the onboard gfx over vga as it's disabled in bios.

Also PowerDVD 7 doesn't recognise the onboard Intel X3500 gfx as capable of playing blueray so that won't work.

I'm not really sure what else to try.

A few things to try first (note, I assume you are using a DVI/HDMI cable):

1. Check in your TV manual which input is reccomended for PC (HDMI not VGA). Use that one.

2. Hook you PC up to a monitor. Set the resolution to the native resolution of your TV and a frequency that it will accept. Shut down. Plug in to TV and re-boot.

3. If that doesn't work, try same again but on 2nd DVI socket on graphics (if you have one).

4. Not my field of expertise, but make sure that if you want to use your 3870, you have it plugged into that and not the onboard graphics (sounds daft, I know). I'd try and make sure any onboard graphics are disabled.

BTW, you should be using the 3870 for Blu-ray playback, which it will do fine.

Thanks HummuH1

Until i crack this i'll reset cmos which will enable the onboard gfx for now, i've bought PowerDVD 8 Ultra which supports Intel G35.

Gaming will have to wait till a sort it out, the gf is going nuts cause i spent a wad of cash on my HTPC and she can't watch a film on it lol

Everything works fine with the onboard graphics now after i removed the hd3870 and reset the cmos, blue ray plays well on PowerDVD 8 Ultra.

From reading further it may well be a problem with the DVI to HDMI dongle which Sapphire supply with the card, i'll buy cable and try that.
