Hello,
I have just bought an AOC 2436swa 24" monitor but my ATI radeon HD5770 (dual DVI) graphics card won't detect it and gives no signal. I am using the VGA lead that came with the monitor and a VGA to DVI adapter. When I remove the Graphics card and connect monitor to onboard HD4200 radeon VGA graphics it works fine. Before this monitor I was using my LCD TV via a similar adapter HDMI to DVI which I never had any problems with. I have tried to solve this problem to no avail so if anyone has any ideas could you please help. Thanks.

Hi, and thanks for prompt response, the connectors on Graphics card are both DVI-I dual link judging from your link. The adapters I use are both DVI-D dual link for VGA and HDMI, so this may be the problem. Funny thing is the HDMI to DVI-D adapter works fine for TV, yet the VGA to DVI-D adapter will not work.....

Anyway, I shall buy a VGA to DVI-I adapter and try that, many thanks for help :)

HDMI is like DVI-D a digital signal and therefore explains why it work!

Ahhhhh, I specifically bought the same kind of DVI adapter for monitor thinking that cause it worked with TV I would have no problem. Thank you for your help, I now understand a little more about DVI connections.
