Resolved Using 3 monitors on Radeon HD 3450 card

I have a Radeon HD 3450 video card installed on Windows 7. The card has a VGA, HDMI and DVI out ports.

I currently have 4 monitors running:

1. 1 on the cards' HDMI port
2. 1 on the cards' VGA port
3. 1 on the computers' onboard VGA port
4. 1 on the computers' Display port

When I plug a 5th monitor into the video cards' DVI port, the monitor indicates No Signal yet, when I go to Windows display settings the 5th monitor is listed. When I extend the desktop to the 5th monitor, the one on the cards' HDMI port goes out saying No Signal.

Question is, can I not run 3 monitors off the card?

Thanks for any insight.

 

Thanks Evan. I looked at he site for an answer but that escaped me.

 

Your best option would be to install another graphics card - but, because the GPU is often the most power hungry device in our computers, you MUST insure your current PSU has enough horsepower to support the increased demands of another card - and your case is providing enough cool air flowing through the case to exhaust the added heat being generated. If neither is sufficient, then budget for a new PSU and/or case too, and set them up before installing the new card.

Alternatively, you might be able to use a graphics splitter but I have never felt they were ideal, except when needing the same display on both monitors - as with presentations in a large room.

 

Thanks Bill - I will look into the options you suggest

 

I said above to consider a new case if that case does not provide enough cooling. While it is the case's responsibility to provide enough cool air, I should have said to first inspect your current case and see if you can add additional fans, or replace the current fans with better (more CFM) fans. If your current case cooling is limited or already maxed out, then get a new case.
