Had a system failure due to my Liquid cooling pump failure. Since then I have not been able to get my XFX R9 270 to display on all 3 monitors. 2 x Acer V176L via DVI and 1 Acer G246HL. All 3 monitors work and all cables re good. I have uninstalled via both conventional and DDU utilities but still can't all 3 to display simultaneously. Not sure if it is the card, or drivers but i could sure use some help.

UPDATE:

Hi all, thank you for your input. I'm back to good. AMD support gave me step by step by step instructions many of which I had already followed. I also found the Active Display Adapter was making intermittent contact.

still some confusion on my part as I was under the impression that the two DVI connected monitors had to be identical, with the 3rd (or greatest) DP connected. I tried that but it didn't work. So current configuration is as follows: 1 Acer V176L via DVI,  Acer G245 via DVI, 1 Acer V176L via DP with custom resolution Short answer I guess is if it ain't broke don't fix it. Any thoughts ????

Thanks again

If your pump failed and the card overheated, it is possible it damaged it.

Thank you I've considered that but it seems that all 3 connections work though not at the same time. Also I may have been unclear in the fact that the liquid cooling was for the processor only, still, you've a valid point.

Since my original post I have been able to download and instal adrenalin without the 1603 error. I have also reconfigured my connections reference above to be

Acer G246 via DVI

Acer V176L via DVI

Acer V176L via Display Port to DVI  --------> This is showing no signal  and is not detected

Some GPU cards you need to install an Active Adapter to get the third monitor to work. Here is a comment from a Overclocker.net concerning your R9 270 GPU card and using three monitors: R9 270 Refuses to Run More Than 2 Monitors...? - Overclock.net - An Overclocking Community

In order to use three monitors simultaneously, one of them needs to be hooked up via an active display port dongle. There isn't really a way around this, unless he's using one of the few new cards that happens to have the hardware support for three displays over DVI/HDMI. I believe the only cards that support this are in the R9 series.

I run 3 or 4 monitors from a pair of cards, but I hook up a max of 2 to each card. I need to disable crossfire in CCC to get the third and fourth monitors working. That or shell out for active DP adaptors.

E: Can't read the title :/ I'll look into the specifics of support for 3+ monitor support. What inputs are each of the monitors on, and what specific card is it?

E2: It appears to be only the R9 290 series cards that support 3 monitors from a single card without display port. The R9 270 is a rebadge of the 7870, which doesn't have the proper hardware to support it. There won't be a solution in software because the hardware simply isn't compatible. Your best option is to find an active DP adaptor, and plug it in. I've seen them for as low as $30 or so -- bought one for my dad's rig, and he's running a triple monitor setup off of a 5770 using it.
