Custom Resolution Utility (CRU)

I am using AMD omega drivers 14.12 drivers. I have 3 Seiki 39inch monitor/tv in eyefinity.
They are currently hooked up as follows 1straight HDMI, 2nd HDMI to DVID, 3rd HDMI to DVID to a 290x video card.

I have found many issues attempting to get this to work up until now. It may have something to do with eyefinity and custom resolutions/refresh.

Problem im having:

Monitors by default will not work in eyefinity unless i modify with CRU after pixel patch is applied.
And i have to do the following to make it work. I have to be at 61hz refresh rate if i do any other refresh rate even lower than 60 i get screen blanking intermittently. 61hz shows up as 60hz on my monitors OSD. Also, i have to uncheck "include extension block" for eyefinity to work properly.

I noticed with this unchecked, my resolutions offered in CCC show no HDTV but PC standard resolutions.
If i try to setup eyefinity say 100hz with include extension block checked, my 2 displays connected to the DVID ports display and odd resolution but proper refresh rate.

I.E. = 1 monitor@1080x1920-120hz displays fine(HDMI only) the other 2 display 960x1920@120hz.

The problem is HDMI and DVI signals are not exactly the same, and you're using adapters without considering the limitations. HDMI always uses one link, while DVI uses two links above 165 MHz (or 230 MHz with the patch), so the TV is only receiving one of the two links with DVI and is losing half the horizontal pixels at 100/120 Hz. This should not be happening with the extension block enabled, but I'm not sure how the R9 290X handles HDMI signals on DVI ports.

You need to decide if you want all the TVs to work as HDMI or as DVI. Either import the hdmi-audio.dat file on all the TVs to treat them as HDMI, or disable the extension block on all the TVs to treat them as DVI. Of course with DVI, you won't get any audio, and you'll need to use a special version of the patcher to always send a single-link signal on dual-link DVI ports: https://www.monitortests.com/atikmdag-pa...sl-1.3.zip

Starting with the next version of the patcher, you can just rename the file instead of downloading a separate version.

At least one of those methods should work. If you're still having problems after that, then there's a driver bug involved.
