So I tried this, but when Windows saw the card it only recognized it as a standard VGA card even after a reboot. I did a quick SW search and saw a question from Jan 2013 where a guy had a similar problem, and according to the post, he got it working by uninstalling the AMD software and drivers and letting Windows pull down the driver. I can use both display port or DVI with 1 display port or the other but not all 3. When I logged into Windows (as a domain admin), Windows and the AMD software can see the 3rd monitor, but it simply won't display on all 3 monitors at once. While the computer boots up, the BIOS and Windows splash screen shows up on both the diplay port to DVI monitors. I grabbed the latest drivers from AMD and installed the card. The Firepro has 1 DVI port and 2 display ports, and it came with 1 display port to DVI adapter (according to Newegg it is an active adapter but according to a post on an AMD forum, it ships with a passive adapter) so I purchased a second display port to DVI adapter (Newegg didn't say if it was active or passive). I was asked to try to stay under $400 per card, so I got the AMD Firepro v4900 specifically because the datasheet said it supported 3 monitors. So for the user which has 2 monitors, I bought an nVidia Quadros K600 and it seems to working ok. The other user has 3 monitors (all DVI input). They both have the same computer (HP z400 workstation with Xenon processor, 10 GB RAM, and 1 TB HDD running Win 7 pro 64bit). You can either apply the EDID from the display (if connected) or load a *.bin file in the local directory (select ‘From File’ and Browse to the file).ħthSense provides a collection of available EDIDs, located in: C:\Program Files\7thSense\Delta\Utilities\EDID Files.I was asked to research a replacement video card for our 2 CAD users. Select the EDID that you want to use and change the properties underneath. This is important for Working in 10-bit Colour Depth.
Color Depth 8 bit or 10 bit depending on output required. Bandwidth should be changed to 5.4 GHz for higher output EDIDs, e.g.
Bit Rate : dual link or above, 5.4 GHz, otherwise 2.7 GHz.The large + will add an EDID to connections with a ticked check box.The page icon downloads the current EDID, in this case, the PLE2208HDD EDID from the connected monitor.The Magnifier shows raw information about the current EDID.
