Hi All:

Have any of you managed to get Eyefinity working with 120hz?  I'm using a Sapphire 290x Tri-X and I'm trying to get my 3x1 setup working.  I've contacted Sapphire Support and they told me 120hz + Eyefinity is not possible, with no additional information (language barrier and all).

Please post how you guys managed to get your setup working at 120hz, if it is indeed possible.  Would like info before I purchase an active displayport to DVI adapter.

Thanks!

Hey gren77,

It is possible to have 120hz Eyefinity setup as I've been running this kind of setup for a while now.

I'm currently running 3 XFX 290's with a 3x1 (+1 extension sometimes when I feel like it) monitor setup.  Monitor's im using are 3 ACER GD235HZ and currently using 2 DVI-D and DVI-D to Displayport Active Adapater.  Resolution of 6048x1080 (bezel compensation)

In order to achieve 120hz Eyefinity you will need to asically what I've done: DVI-D Cables and DVI-D Active Adapters.

The current adapter that I'm using is:

Accell: http://www.amazon.com/Accell-UltraAV-B087B-002B-DisplayPort-Dual-Link/dp/B002ISVI3U/ref=sr_1_3?ie=UTF8&qid=1391647000&sr=8-3&keywords=DVI-D+to+DP+active+adapter%2C+accel

However, I am currently changing my setup to incorporate HDMI (1.4) cables to see if I can get a more "stable" 120hz Eyefinity setup.

If you or anyone else have any questions about 120hz + Eyefinity, please feel free to ask.

Hey Lobsterbread:

Thank you for the response.  I guess I'd have to get the Accell cable converter for best results, at least you confirmed that it's workable indeed.

I read about presets yesterday and managed to get it running as a temp solution for getting 120hz partially.  Will just have to pony up for the converter when I can afford it

About HDMI, my third display is using HDMI and it looks rather... fugly: slighty blurred text, slightly off colour.  I am also limited to 1080p @ 60hz as max resolution and 1680 x 1050 @ 75 in terms of pixels.  How are you planning on utilizing your HDMI cables?  I heard you can't get 1920 x 1080 @ 120hz given HDMI 1.4.

It's actually an experiment I'm trying out and want to see if HDMI 1.4 is a viable option for 120hz eyefinity.

One of the main reasons why I'm shifting to test this is because I've had numerous issues with a 120hz Eyefinity setup.  The most recent issues being:

- Because of the USB power needed for the DVI-D to DP, you get this "snowflake" effect from time to time.  i.e. every once in a while, when you're switching between 2d and 3d applications (going from games to desktop and vice versa) the monitor that is using the active adapter will become blurry with odd colors and visuals.  To resolve of this small issue would be to unplug and replug back the USB portion of the adapter, or turn the monitor on and off, or change your refresh rate from 120 to another value and change it back as this will "reset" your monitor.  Personally I've been dealing with this issue for a few years and slowly getting tired of it.

- An odd bug where in games my eyefinity setup would "crash".  The monitor connected via the active adapter would turn off suddenly and would revert the two remaining monitors (powered through DVI-D cables) back to displaying 1920x1080 with the same image.  I would then need to unplug and replug the USB portion of the active adapter to get the 3rd monitor active again, but this method would sometimes crash my entire system.

TL;DR

Long story short, I want to remove the DP active adapater from this setup to try and remove not only this "snowflake" issue but also the issue fo the 3rd monitor shutting off during an "eyefinity crash".  I'm hoping that removing this one pesky object will help, but I won't know until the parts come in, which is this Friday (2/7).

I'm using the latest standard of HDMI 1.4 which allows HDMI to go up to 4k resolutions or 1080 @ 120hz / 1080 in 3D.  I'm also hoping that these newer/nicer HDMI cables will help with the fact that "HDMI kinda sucks".

This is my plan:

I've ordered 3 HDMI 1.4 cables:

http://www.amazon.com/gp/product/B005GGTTZ0/ref=oh_details_o03_s00_i01?ie=UTF8&psc=1

I'll be replacing the 2 DVI-D cables with the aforementioned HDMI cables with a DVI-D to HDMI adapater:

http://www.amazon.com/gp/product/B00CCVKQRM/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1

I'm hoping that with these, coupled with my monitors, the HDMI cables will be able to handle 1080p @ 120hz.

Just incase, I've also purchased an HDMI to DP active adapter.

http://www.amazon.com/gp/product/B00ESFF5O4/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

 

Hoping that removing DP from the equation will do something, albeit it may only be removing the "snowflake" issue; as this issue is due to the active adapter.

 

Anyways, that's my plan with using HDMI to setup a 120hz Eyefinity setup.

I've read up a bit on this and they point out that most monitors support either DVI-D Dual Link or Displayport.  Hope you can post your results here

Have you tried external power for the USB cable of your converter? I heard that sometimes it really needs a power brick that provides 1 amp or more (as provided by power adapters from Apple) as opposed to a USB slot on the back of your motherboard.

And I thought the occassional blinking on my old NVIDIA setup was bad, but I guess restricting your connections to DVI-D solved a lot of problems for NVSurround.

Yeah, the monitors that I use (ACER GD235HZ) have DVI, HDMI and VGA.  (Not entirely sure why VGA is was placed in considering this is a 120hz monitor...)  I'm hoping to use the HDMI ports and hoping that they're up to snuff for what I want them to do.

I will be more than happy to post my results here once I receive them.  Unfortunately, UPS loves coming to my place last so I won't be able to test until late night Friday.

I'm hoping to finally be rid of this "snowflake" crap and have another method in which to setup 120hz Eyefinity.

Once you go 120hz and eyefinity, you don't want to go back.

 

In regards to connecting the USb cable to an external power source, I've never really thought about it.  Kind of just thought "hey, USB goes to USB port. Done."  If my test somehow falls onto itself, I'll be sure to try that method out.  Thanks.

And yes, using strictly DVI-D is a god-send.  Removes any and all variables for when it comes to 120hz/eyefinity and simplifies it.  Also very glad that the R9 series cards have 2 DVI-D ports.

 

Again, I'll post my results probably around 21:00 EST on Friday.  Hoping that all goes according to plan.  If it doesn't, I hope my backup plan (using HDMI to DP active adapter) works.  Here goes nothin'.

This experience sure was an eyeopener.  I always did learn the best through mistakes.  (or not thoroughly researching what I'm doing in the first place and tend to take things at face value)

Unforunately it would look like because of the specific monitors I'm using, I will not be able to setup a 120hz Eyefinity setup via HDMI.  However, it is possible.

After scouring through the web for a while today, it appears that I, specifically, cannot setup a 120hz Eyefinity setup due to one issue: my monitors.

In order to setup 120hz Eyefinity display with HDMI, you would need the following:

- HDMI Cable: Almost any.  Apparently all HDMI cables are basically the same with only slight variances between them; mainly whether or not it supports Ethernet.

- HDMI 1.4b or newer HDMI Chipset on your GPU.

- HDMI 1.4b or never HDMI Chipset on your monitor. (I'm missing this piece)

 

The cables are generically the same, the only determining factor (in my case) would be that my monitors' HDMI Chipset does not support 1.4b standards.  It only supports 1.3. (FML)

 

Well, lesson learned.

Experiment: Failed.

 

Edit**

Also, I've tried this combo; which failed.

- HDMI to DVI-D adapater.  Adapter connected to the monitor while HDMI to HDMI port on R9 290.

- Thought about using a DVI-D to HDMI adapter on both the monitor and video card while using an HDMI cable for kicks but got too lazy.

 

I'm hoping there will be another viable method to remove the Active Adpater needed for 120hz for my setup.  One can hope, right?

That's a big shame

I've read up on HDMI and 120hz and found out that 120hz was only supported via DVI-D on my monitor (Asus VG236).

I've yet to encounter a monitor with HDMI 1.4b that allows 120hz in a non 3D setup.

Signs point to DVI-D: even some displayport enabled monitors seem to be a bit finicky.

Did you get to try powering USB via external power brick?

Hey gren77,

Sorry for not posting earlier.  It would appear that even powering the USB via an external power brick resulted in issues.  Not entirely sure why it would still lose power/not have enough power.

Still experiencing "snowflaking" and Eyefinity crashes.

Still messing around and was able to play BF4 for about 5-6 consecutive hours without Eyefinity freaking out on me, after switching some settings around on my system; but still testing.

I also decided to change some power settings to the USB ports to try and see if that'll relieve the issue.

 

But, like I said in my previous posts: It would appear that 120hz Eyefinity setups are possible with almost every optical connection; just have to make sure every component is able to handle the bandwidth needed.

Regards.
