So I have been using my monitor over VGA. However, recently I decided to switch to dual monitors. Ideally, the monitor I've been using would be running over DVI as the other monitor I found is older and only has VGA in. However, when I have everything set up, only the monitor running over VGA works. I know both work, I've tried switching out the cables, Windows acts like the DVI monitor isn't plugged in, and the DVI monitor gives me a "No Signal" error, not a "Cable Unplugged" error. It doesn't matter whether I have the VGA monitor plugged in or not, the motherboard's DVI out does not work. I was wondering if there was some setting in the BIOS that needed to be changed for DVI or if I need to contact Asus. I have also been considering getting a low-power AMD Radeon R7 240 to configure in dual graphics for the second VGA out.

My system specs:
CPU: AMD A10-7700K
GPU: Onboard Radeon R7
Motherboard: Asus A55BM-A/USB3
RAM: 8Gb G.Skill Sniper 2133MHz
HDD: WD Green 1Tb
OS: Windows 7 Pro 64-Bit

Any and all help will be appreciated.

It's probably not a bad idea although you'll then need to configure the dual graphics which should be no problem, although configuring your current setup shouldn't have been troublesome either. If you don't have a specific card in mind I'd recommend the Sapphire R7 240. I've used them is several solo and dual configurations and they've been trouble free with good performance, for what they are. Sapphire is pretty much known to be a winner in the GPU world.

Let's start with the basics. Have you right clicked on your desktop and selected either properties or resolution, depending on your OS version, and checked to see if the monitor is even being recognized by windows? Are you sure you have the correct DVI cable as there are several types and some of them will interconnect but might not work correctly depending on your hardware support.

The manual for your motherboard says it is a DVI-D port and can be used with any DVI-D compatible device. It says DVI-D cannot be converted to output RGB signal and is not compatible with DVD-I. I've heard the two are sometimes compatible depending on hardware on both ends and other times, as in this case, the information seems to suggest otherwise. Make sure your monitor is DVI-D and that the cable is DVI-D.

There are also several other DVI specifications. Not that I question your level of technical expertise, but it's a mistake I've made myself when not paying attention. Make sure you don't possibly have one or the other wrong and now maybe have some bent pins or just incompatible hardware. What is the monitor model number?

Yeah, I've done everything you mentioned and still no dice. I've looked up the specs on the motherboard and monitor (an Acer X203h) and everything matches. Windows acts like nothing's plugged in. If something's broken on the motherboard I'm thinking I would rather buy a R7 240 to put in dual graphics for the extra VGA port...
