I have monitor one connected to VGA output. It works. Have HDMI output connected to larger monitor. PC can't seem to detect it.

What are your system's basic specs? Specifically, what GPU (video card) and version of Catalyst are you using?

I'm using the Radeon HD 4650, I went into the Catalyst and all the typical ways of detecting the second monitor didn't seem to recognize it.

What version of Catalyst and Windows are you using? Might just need to go to ati.com and get/install the latest version of Catalyst Software Suite (11.2).

BTW, if only the HDMI connection is used, does the system detect the larger monitor? Also, is the larger monitor configured for the HDMI (as opposed to a VGA or DVI) port?

Yes it does work with just the HDMI monitor connected, but ironically when both are connected, I don't see anywhere in the catalyst box to choose between VGA or HDMI.

If Catalyst is installed, right click on the desktop. Select Catalyst (should be at top of dialogue box). Look at selections on left side of Catalyst window.

I looked there. couldn't find it. I checked to see if there was an updated driver and the one I have installed is the most recent. Still unsure about the model number. It says both: Radeon 4650 but in other areas it says 4870. But I can't imagine there being that much difference between the two. I just won't recognize that thee is even a second monitor attached. I've reseeded the HDMI cable on both ends. The back of the card has both HDMI and VGA ports so it must be capable.

How many video cards do you have installed? Download speccy (piriform.com/speccy) and get a good run down of what is in your system. Please post the results.
