200 DPI for a phone 16" from your face. Most people don't sit that close to their 27" monitor. The "retina distance" for 27" 1440p is 32".
A 2560x1440 monitor at 27" (the usual size) is about 109 DPI. "Retina" resolution is usually considered to be 200 DPI or higher.
Nice, any luck with overclocking? Going from 60Hz to 96Hz is a big difference even when you are just tooling around on your desktop.
The 39" VA panel itself is just fine. It is capable of handling 60Hz refresh. There is no such thing as a "HDMI 1.4a panel" - the input electronics are separate components. It's no more an inherent limit of the panel than is the fact that some Korean 1440p monitors can only take DL-DVI. The problem is that Seiki did not include a DP 1.2 MST input on their 39" 4K TV, so there is no way of getting a 3840x2160@60Hz signal to the panel.
I agree it's unlikely this could be fixed by a firmware update. The only way that could happen is if it could upgrade the HDMI 1.4a port to a HDMI 2.0 port - questionable at best. Even then, you'd need a video card that supports HDMI 2.0 (or that can itself be flashed to support it). But Seiki could fairly easily release a version of their 39" TV that had 60Hz 4K support through DisplayPort, and I believe they have made some statements on social media to the effect that they plan on doing this. Perhaps it is these statements that were misinterpreted.
Never tried it actually. You have my interest on this subject now. :hmm:
I was just about to make my way over to your thread KaRLiToS. I am contemplating biting the bullet with a pair of 290 or 290X. I figure I could set them to mine while I work to help off-set some of the cost, but a perusal of your thread showed issues with Crossfire and multi-monitors at this resolution or was that just when running Quad Crossfire?Hi, just wanted to tell, GTX 670 or GTX 670 SLI won't really cut it for 7680x1440.
But GTX 780 SLI and you are
PS Just ordered my third monitor, so I am getting excited.
Which one did you end up getting?
Those Korean monitors are hard to beat for value. I'm just scared with the warranty personally. That's why I haven't bought one yet.

Zardnok: KaRLiTos clearly has experience in multi-monitor setups so I'll defer to him on his advice about them. I will tell you that I had rig2 below with various video cards when I started down the path of a 3 monitor setup and give you my impressions.
I had just upped the cpu from a 2500k to a 3770k when I decided to up my Acer 24" 1920 x 1080 monitor from 1 monitor to 3. At that time I was running an AMD 6970, which was a decent card. I purchased 2 more identical Acer monitors so I could have a 3 monitor setup. I realized I needed a displayport so I purchased an active displayport. Expensive but it was worth it. I setup Eyefinity and finally got it working. What I noticed first was I really didn't have the "horsepower" to run 3 monitors at high resolution (5760 x 1080) with decent frame rates on the newest games and a single 6970. The AMD 7970/7950 had been released but so had the Nvidia GTX680. I had been an AMD loyalist both cpu and gpu for quite awhile but Intel's Sandy Bridge and Ivy bridge cpus "cured" me of that so I really thought about it and then purchased a single Nvidia GTX680. It had quite a bit more power than the AMD6970, and eventhough it didn't have 3GB vram like the 7970s I found it ran the 3 monitors better. The Kepler bug kept biting me and I ended up buying identical EVGA GTX670 FTWs which use the GTX680 pcb. I continue to run these cards in rig1 below (I "had" to get into custom water cooling so I jumped to a 3930k rig ROCK SOLID). Anyway, I sold my 3 1920 x 1080 monitors to go to a single 2560 x1440 27" setup (Exact same Achieva you have) and use it on my 3930k rig with dual 670s. It's fast, beautiful and but for the most exacting settings, never runs out of vram.
I now have a GTX780 classified in rig2 below. Simply put, it's a BRUTE. It's not as fast in 3D Mark Firestrike as the dual 670s but close enough (@11000 for both 670s vs 9700 for the 780).
If you run 3 2560 x 1440 rigs your overall resolution is 7680 x 1440. My 2 cents? Don't "cheap out" and buy a second 670. Sell your present one and buy either 2 780s or 2 R9 290s. Perhaps start with a single one of these then go to a second.
Don't get me wrong, I think my 2 670s (some of the best ones made which are water cooled and able to be overclocked) could power 3 2560 x 1440 monitors "OK" but for decent gaming you'll need to "up the ante". I think KaRLiTos confirms this by suggesting 780s in SLI.
Thanks for the input Gusk. I am pretty much at this conclusion already. It would be MUCH easier if I could mine with the 670s, then I would pick up another, try it out, and mine with it to cover the cost. If it didn't give me the performance I wanted, I could just move it to another box and keep it mining, but alas, the 670s are not miners. This leads me to the conclusion that I am going to need to replace my current 670 with two newer cards to run this resolution which is fine since I budgeted $2k for this upgrade total and after both new monitors and a fancy Ergotech stand, I still have $1250ish remaining for video cards and an active display port adapter.
My decision now becomes two of what... I wanted the extra VRAM on the 290 series cards, but if the display port is unstable in Eyefinity mode using Crossfire then it pretty well crosses them off the list and leaves me with SLI 780 or 780GTX. I then worry if I will have enough VRAM for this resolution. I am really tempted to just buy a couple of Tri-X 290X and trust AMD to get the driver issue or whatever it is causing the Cross-fire/Eyefinity glitches with Displayport resolved. Just hard to dump $1400 on video cards for a "hope it works".
