My Sapphire adapter died on me, but during the time it worked i rma my bizlink and the new one works like a charm.
Now i just have to muster the time to rma my sapphire adapter.

Anyone try the Monoprice active dual link adapter?

I have a post about it working @ 120Hz using a single monitor without ever having flickering issues.

Here is my post:

Hello there all,
First off just say sorry if iv missed anything through the thread due to flicking through it after picking up on this and sounding like issue's i have now...

Just RMA'd my ROG HD5870 due to my centre screen flickering on the top third mostly and was found no fault but still dose it on return..... but didn't think it may be the Sapphire DP adaptor which is next to new may be at fault.

Again sorry for jumping in on the thread in the excitement finding something that sound's just the issue i am having..

Be interested hearing anything about this, it's just the bit's in the thread about powering with a USB socket and my adaptor do use USB to draw power

J.

Figured I'd toss my 2 cents in.

I've had the flickering issue since I went to Eyefinity w/an Accell B087B-002B DP/DVI adapter. All three screens would flicker when doing things like entering fullscreen mode or switching shows in Netflix. Also, sometimes when I booted up the LCD that is on the DP/DVI adapter would not even turn on and I would have to power off then on again to get it to detect. I tried the iPhone charger, but that didn't work. Recently I bought one of these http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=310281748003 and since installing it I have had no problems. I've only had it for a few days, so I will have to report back in time to see if it truly works but so far so good.

I can now confirm that the Monoprice Adapters work quite well; so long as you stay within the bandwidth limitations you wont have any link failures or flickering.

Here is my post about getting eyefinity to play nice with 120Hz monitors.

http://widescreengamingforum.com/forum/forums/multi-monitor-gaming/amd-eyefinity-discussions/17699/3-x-120hz-eyefinity-build-log-benq

Running them at 100Hz to stay within the bandwidth limitation of the adapters and for compatibility with most games.

Without all three monitors using displayport, your DVI monitor will exhibit screen tearing. I plan on getting a 6990 to solve this issue for me and the extra performance it will bring. Displayport monitor must be the primary display when creating an eyefinity group. You may also need to disable DDC/CI for your monitor and use powerstrip or ati tray tools to enforce/lock the refresh rate to prevent windows or the driver from changing the rate (possible link failures if not done).

Probably will not get 120Hz to work reliably until we get adapters witch support the max bandwidth of Dual Link DVI (330MHz).
The monoprice adapters support 268.5MHz of bandwidth. To support 120Hz without problem; you would need an adapter which supports 283MHz of bandwidth.

Have 2 apple adaptors active for 120hz.
major headache, couldn't even set eyefinity without screens going 640x280.
went and bought a usb charger, and got it to work.

wee...
BF3 now looks marvelous.

Stop the insanity! Why is everyone having so many problems with screen tearing, artifacts, and expensive active adapters?

I recently purchased:

http://www.ebay.com/itm/170692229239?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Which is a PASSIVE displayport -> VGA adapter. $12 shipped. Works great at 60Hz, 1920x1080

The other monitors are HDMI-> VGA, and DVI -> VGA. There were no problems configuring monitors in CCC, and when I disable eyefinity profile, I get my normal (centered) desktop back.

Unless your are going beyond 1920x1080 on a single monitor, don't mess with active.

I have used HP Bizzlink DP>VGA adapter which (cost 20 euro here in Poland) and had some flickering when my GPU was getting hot. But since I bought XFX active DP>DVI adapter (20 euro one) the problem disapeared.
The funny thing is that it doesnt require any of those fancy usb plugs for more power. Its just a simple adapter.
Also tested on HiS 5770 1GB, XFX 5870 1GB and Sapphire 6950 2GB - didnt notice any problems with XFX adapter. (HP Bizzlink had some flickering on each of these cards which depended on GPU's temp.)

Well actually there's no such thing as a dp->vga passive adapter, dp doesn't support vga natively as it is digital. It just pulls the power off the dp port to convert the signal to analog.

Hi,

Lately I've been noticing some flickering during games like Fear 3 and Just Cause 2 that were never there before. Looks like trying to watch a scrambled cable channel. Seems like it started after upgrading from 12.3 to 12.6 or 12.7. This is with eyefinity multi-monitor setup with two dvi's and an active display port mini adapter to dvi on a triple xfire 6970 rig. Disabling crossfire mode has no effect as it still persists.

So I tried testing each video port one by one to see if I could pin it down to a bad dvi port or maybe displayport adapter. Each port tested out cleanly without flicker individually. However with all three monitors attached in mirror mode (eyefinity turned off) the displayport monitor flickered and would spread to other monitors only if eyefinity was turned on.

Gets even more curious when rolling back to 12.3 the problem disappears and the flickering went away. So either I have a bad displayport adapter or there is something wrong with these new drivers?

Any ideas?

Thanks
