Received a new monitor today, a 27" Iiyama job. When first connecting through DVI or HDMI the screen just remained black but a mouse cursor was there, on my windows 7. Graphics are up to date, GeForce GT 240, motherboard is all dvi/hdmi compatible.

 

Did some windows and java updates, rebooted tried again. This time they come up with just the windowns logo with quite a thick black perimeter. I have googled it to death to no avail.

Does your motherboard have an HDMI or DVI port on it?

Ok so you did try plugging the DVI cable into both the Graphics card DVI port and the Motherboard DVI Port?

omg I didn't realise there was one on the grpahics card aswell DOH!!! lol thanks I found it now. But I have to ask why is there two of the same connection? it's vga and dvi into the grpahics, then dvi vga AND hdmi further up the tower. There's no hdmi in the graphics, so how do I connect via hdmi?

Well Your motherboard seems to have an integrated video card but you always want make sure you're using the ports on the graphics card. DVI and HDMI are the same thing so you don't have to use the HDMI on the graphics card if you're using DVI.

but hdmi sends the sound through yet I'm not receiving sound thru the monitor speakers on DVI? Also I have the standard motherboard set up with grpahics card plugged in at the bottom of it. And then there's more vga and dvi outputs hihger up just under the PSU, this seems to have been the standard on any pc I've bought. only those top two outputs seem redundent..?

Well it depends if the monitor you bought has speakers in it. You always want to use the video ports on the graphics card itself because that's where your going to get the best quality. If you use the video ports on the motherboard than the video card is useless.

dvi doesn't carry sound, google says.

 

well if the ports are on the motherboard then surely they should work? What's the HDMI port there for it does nothing?

Yeah DVI doesn't carry sound but HDMI does. The only thing is though is that even though your monitor has an HDMI port doesn't guarantee that the monitor has speakers in it to get sound through the HDMI cable.
