Make sure you got dual link DVI cable:
The cable that came with my monitor was single link DVI.
The monitor still got detected by Windows becasue the DCC channel on the wrong DVI cable was still functional.
BTW what video card are you using?
If your video card got another DVI port, try it as well, since not every DVI port is dual link inside.
If you want to run the monitor from onboard Intel HD graphics, you need to use DTD Calculator to add a 40hz DTD registry entry.
Thanks. I think this might be what is wrong. I am using the cable that they provided because it said it came with a dual link DVI cable... Here are the steps that the seller has given me to test. I have done all but replace the cable with no success. Next step is to buy a new cable and test it out. As for the vc, it is below in my sig. Sapph 7970. Here is what they said:
Well received your photos.
As you think, I also do not think it damaged monitor.
Your problem is now "black screen"
Monitor is powered on, but you can not see windows screen.
In this case, 2 possibility is there.
1. screen resolution rate is not matched.
2. DVI-dual link cable.
First of all,
Connect your 25" monitor.
and then, set the resolution rate as 1024*768 or less
Turn off the computer
connect QNIX QX2710 monitor only
Check out your DVI-D cable pins are not bent at both side.
Turn on the computer.
Then you can see 27" screen.
Monitor LED is off, that means your monitor does not get the signal from graphic card.
In most case, resolution rate setting failure.
Try to 2~3 time like above method, if you failed.
