Is this possible? My setup is this. I am looking for information on how to get this accomplished. I have a Radeon HD 6970 GPU. Right now I am using the 2 DVI outputs and the DisplayPort to DVI adapter to output a triple monitor display to 3 ASUS monitors. That has been working fine.

What I would like to do is duplicate one of these displays (would be nice to be able to choose, but not a big deal) to another monitor. So 3 monitors would be extended, and 1 would be duplicated. The end goal of this is to run an HDMI cable from the computer to my TV and have one of my displays show up on my TV if desired. I turned on on-board graphics on my MoBo (Gigabyte Z77X-D3H). It shows up as one of the displays. I have a small TV plugged in, via HDMI, to the motherboard, and the TV shows up as a 4th display on my "Screen Resolution" setup screen in Windows 7. However, there is no option to duplicate the display here, only to extend it. Am I doing something wrong? How would I get this setup properly?

Please help! Football season has started!

no you already have an active displayport adapter for the third screen and you will only be using 2 of the legacy connectors dvi and hdmi are basically the same.

on ati cards the problem is that you cannot use 3 legacy connectors so you cant use 2 dvi and hdmi on your card the third monitor always has to be displayport, but you can still use any 2 of the other legacy connectors.

So that was my original idea. But I was reading that it was impossible for my graphics card to output via HDMI, DVI AND DisplayPort at the same time. Is this true? If not, how do I set it up?

He is already using 2 legacy outputs (2x dvi). You can still use a splitter though, just keep in mind that you wont get sound with this method.

-From your video card run a DVI to HDMI cable to an HDMI splitter.
-From the splitter run an HDMI cable to your TV.
-From the Splitter run an HDMI to DVI cable to your monitor.

Yea that is what I was going to do originally. But I do want sound to be replicated to my TV as well. The TV would be about a 50-60 foot run through the attic, so I don't think an optical cable run would be sufficient.

Ok so I got it working as intended for the most part. The GPU is outputting one display via DVI, one display via DisplayPort to DVi, and the central display is output via HDMI to an active HDMI splitter. From the splitter, I have a cable running to the monitor and to the TV. I was able to get audio and video to go to both the TV and computer. The only issue I have now, is the monitor in the center is not displaying the video properly. Before this setup, there was a perfect aspect ratio across the board, all 3 monitors displaying 1080p. All 3 monitors and the TV are set to 1080p, but the central monitor looks "zoomed in" slightly, and has a 1/2 inch black boarder around the display. Any idea what is doing that?

That is what I assumed too. I tried that and the aspect ratio options are set normal. I actually swapped out the cable so the cable going from the splitter to the monitor was an HDMI to DVi cable. So the monitor is back on the original DVI input, but that did not fix it.

go into the ati control panel and find the panel control options, its most likely set to show overscan regions which is causing the problem, you need to reduce the overscan to 0%

if its showing correctly on your tv after changing the overscan it wont show correctly and you will need to change the aspect ratio on your tv after.

You are savior man. Awesome job. The overscan was showing on both monitors, making that adjustment fixed the monitor and the TV perfectly. It looks amazing. Sound and video streaming to both rooms simultaneously. Thank you so much! Is there something I can do to give you props on these forums or something? Sort of new here...not sure how it works.
