I recently purchased an Avatar gaming i7-47770C Desktop PC Intel Core i7 4770k (3.50GHz) 16GB DDR3 2TB HDD Windows 8.1 64-bit computer. Along with that I have the ASUS VS239H-P monitor. It's been running great for 2 days, then a Windows 8.1 error said there was memory management issues. I read that I should boot it in safe mode and take a look at it. I set it to boot in safe mode using system configuration, the PC boots up with everything running fine but the monitor does not respond, saying "no dvi signal" while I have both a VGA and DVI cable connected, which was working fine until I rebooted in safe mode. I'm not sure what the problem is, the computer or the monitor. If anyone could help me with this that would be great, thanks

vga and dvi can be connected with a adapter, try taking one out and seeing if they work.

I have actually tried just using 1 cable, the DVI and the VGA. I've changed the input on the monitor as well to VGA when the VGA is connected.

No they are 100% fundamentally different. DVI is a digital signal and VGA is an analog signal.


OP, make sure the monitor is connected to the GPU, Not the motherboard.

No they cannot. They are completely different ports. they have WAY different pins. You are 100% wrong. An adapter is needed and then the adapter will only work on a DVI port that also supply an analog signal.

Neither is weaker or stronger, just different signals for video. Both can do 1080p exactly the same.

Thanks for the replies guys, the thing that confuses me the most is that it was working up until 2 days ago. I now know that it is not the monitor because I successfully connected my laptop to the monitor. I'm under the impression that the video card in the PC (that I just received in the mail) has died, although it was working for the 2 days I had it.

I actually don't have another monitor to try, but my laptop connects to the monitor just fine.
