HDMI and DVI
-
I got a new computer and the video card seems to be shot. Once I booted into windows it would randomly start to flash, turn blue with vertical lines, then come back to the desktop with a message that the video drivers had crashed. Ok, so bad video card. :mad: I've arranged an RMA and I'm waiting for a replacement. In the meantime, I thought I could use the on-board graphics so that I can at least play around and get everything setup the way I want. I have an older LCD monitor with VGA and DVI inputs only. However, the motherboard only provides an HDMI output. Luckily, the computer came with a HDMI to DVI adapter. I plug it in, reboot and....nadda. No signal at all on my monitor, not even BIOS. The computer does boot (I can hear the windows chimes), but I have no video. Isn't HDMI supposed to be backwards compatible with DVI? Is there some equipment that it won't work with? I'm worried now that the motherboard is the problem and maybe the video card was innocent?!? [Indecently, I connected to the video card via DVI since it has DVI and HDMI outputs] Any thoughts?

check in your bios settings that the onboard video is enabled. I have seen some pc that the bios will automatically disable the onboard if there is a card installed.
Common sense is not a gift it's a curse. Those of us who have it have to deal with those that don't.... Be careful which toes you step on today, they might be connected to the foot that kicks your butt tomorrow. You can't scare me, I have children.

Sound idea, but your logic is flawed ;p

Reminds me of a wireless card I used to have. It had an IRQ conflict and was causing my hard drive data to become corrupt. So sometimes it is not defective hardware, but poorly designed software.

I've removed the video card, so it should disable the onboard, right? Also, can't get into the BIOS since I can't see anything!
the card worked to boot up until you got into windows correct? reinstall the card just to get to the bios. No, it does not necessarily automatically enable the onboard. It could be set to auto, it could also be set to simply "off" Just thinking that it might be worth a shot to check it. Then again I could be completely full of crap and it has nothing to do with your current problem :-D

HDMI is backwards compatible with the digital formats DVI-D and DVI-I, not the analog-only DVI-A. If your monitor only takes DVI-A, you're still outta luck. Copy protection at the video interface level... it's a two edged sword, to be sure.

You might be on to something. I checked the MB manual online (since I'm at work, not working) and the on-board video defaults to "auto" which is described as letting you set up a dual display in Windows. It has another setting for "Enable If No Ext PEG" which it describes as "Activates the onboard graphics only when no PCI Express graphics card is installed.". I'll have to try it again tonight. [Rant mode]But how stupid is a motherboard that, with no where to output video, just happily continues booting instead of switching. Seems to me like it should always turn on the on-board graphics if there's no video card.[/Rant mode] Cheers.

completely agree but, I have a sneaky suspicion that the people who design the things are maybe super smart, but lacking in some common sense.....

What model? It would be a good idea to google your model real quick, because earlier models that had VGA and DVI only supported DVI-A! Then you can at least figure out if you need to borrow a monitor from a friend to fix it, right?
-
Have a VGA to DVI converter too? Maybe a stack of converters will work :laugh: Also, in case you didn't check, make sure the monitor is set to the correct input source, most will switch automatically but not all.
The infamous video source switch :) Do you happen to know if DVI to VGA adapters work for the digital formats of DVI, or just analog? I was under the impression that they only worked for the analog flavor of DVI. Otherwise, you could do a HDMI to DVI to VGA conversion and strip HDCP...

how so?

Agggh! No dice. I put the crappy card back in, booted into BIOS and set the onboard video to be on when there's no card present. Let it boot into Windows on the vain hope that it might have magically solved itself. It was okay for about 5 minutes and then acted up again. Turned it off, removed the dodgy video card, plugged the monitor into the HDMI via the adapter, turned it back on and.....nothing. No signal. Well that was a waste of about 30 minutes. And the b'stards still haven't shipped my replacement card.
