I've been building a new PC and am having an issue with it. My system specs are:
Corsair 750W PSU
Windows 7 Home Premium 64-bit
ASRock X58-Extreme motherboard
Intel Corei7 920 2.66ghz Quad-core CPU
6gb OCZ DDR31600 Ram
1TB Western Digital 7200RPM HDD
Diamond Radeon HD 5870
Hanns G 28" monitor
Now all of the hardware seems to be working perfectly fine. I have Windows 7 installed and it detected everything...BUT I am having a problem. If I try to use a DVI>HDMI cable to connect to my monitor I get no display. Using a VGA (with a VGA>DVI converter) works prefectly. I know there's nothing wrong with my monitor's HDMI port because I was running an HDMI switch with an Xbox 360 and PS3 hooked up and it worked perfectly fine. I hooked up the PC without using the switch and I got no display. I know the cable is not bad because I was using the DVI>HDMI cable with an old Geforce 8600GTS 512mb card and it worked perfectly fine.
I tried it with my old Viewsonic 21" monitor which had also had the Geforce card hooked up to it (I was using it with my old system before I got the new monitor) and I got the same results, no display with a DVI cable. However, my dad has a 21" monitor and when we hooked the card up to THAT monitor and the card is working perfectly fine. So why can I not get DVI with my two monitors (both of which were running the Geforce card) but my dad's (which wasn't running said card) works prefectly fine?
Again, I might add that VGA with my Hanns G 28" works prefectly fine (in fact I'm using it right now).
I seem to recall having a similar issue with my Geforce card and my Viewsonic where after I updated the drivers the DVI input stopped working but the VGA input worked fine. I at first though the cable was dead and got another one but it turns out that it wasn't a cable issue. I wound up having to use some sort of DVI recover tool to get it working again...do I need some sort of tool for this card as well? I can't remember where I found it... I'd really like to get DVI working since its so much sharper than VGA.
Something else I've noticed is that I have to turn the computer on three times before I get display with the VGA cable on my 28" monitor. The first time I turn it on I have no display. I turn it off and turn it on again and it turns ITSELF off half a second after I turn it on the second time. The third time I turn it on there IS display. This never fails - I have to go through this EVERY time I use my computer.
Yeah, I've posted on a few other forums and if nobody else can help me I'll give Diamond a call on Monday. This is an RMA'd card and I had a 5850 that I tried on it that I returned for a refund because it wouldn't work.
It doesn't work with DVI on two monitors (both of mine) but on the third one (my dad's) it works perfectly fine.
Okay, I seem to have solved it. I called up Diamond, they talked to their engineer. They had the same motherboard/CPU, tried the card and had no problems with it. But they said that the card will only work with DVI-I and not DVI-D. So that explains why it wouldn't work with my two monitors but it would work with my dad's, because his was DVI-I.
Now finding a DVI-I to HDMI adapter was tough, I wound up having to order one from Amazon.com for like $5, no place here carried one - they had everything else though lol. Now I just have to wait for it.
