So I have a very interesting issue that just arose. I believe what was working for me to connect three monitors is said to be impossible.

I have two computers with three monitors,

My work computer has an XFX 7850 with three computers all connected through what AMD referred to as "legacy" connections. Two connections using DVI to HDMI cables and the third monitor through an HDMI cable. This has been working since I got the computer three months ago and suddenly two days ago one monitor stopped working when I updated my catalyst control center drivers. I can swap which two monitors are displaying but not all three at the same time. It won't let me save the configuration. I removed all my drivers and installed the driver I was using prior and now that one doesn't work. I tried a mini display port to HDMI cable and still the same results. I have purchased an active display port adapter to get it to work but why did it work prior?

My home computer I have an XFX 280x card with 4 monitors hooked up. I used to have all four monitors working with the configuration of 2 DVI to HDMI connections, 1 HDMI cable, and 1 mini Display port to HDMI cable. Then after one update I could only use three monitors at a time but all four do work, just not at the same time. Why did one stop working after the update and how do the three other connections currently work because according to everything I see online it shouldn't work using the legacy connections.

Could anyone shed some light on these configuration issues? Please don't just tell me I need active display port adapters or different monitors, I'm simply trying to find out why did they work in the past and stopped working.

Thank you for any input.

I think you answered your own question. It was working until you updated catalyst drivers. I had a similar issue with Nvidia latest 344.11 WHQL drivers. As soon as I upgraded the drivers, I could no longer enable Vision Surround to 5760x1080 on my three monitors. I even contacted Nvidia support but they weren't helpful and simply said they could not recreate the issue. I reinstalled the prior WHQL drivers and everything started working as before.

Unless you have a specific reason to need the new catalyst drivers, you should just reinstall your older ones.

I am sorry, I guess I forgot to add this but I completely removed all drivers and installed the original ones I had and still having the same issue. I'm using the drivers that used to work but now they do not.
