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