Pros: - Excellent color/image quality
- Good build quality
- Built like a tank
- Very thin bezel, you could totally tile these
Cons: - only one 4K@60hz capable input over DP 1.2, HDMI 1.4 doesn't have what it takes. Why bother including inputs at all if they can't drive the monitor? This isn't a TV, 60hz or bust.
- No DP chaining capability. Also a real shame.
Other Thoughts: - No USB ports on the monitor. I personally don't care.
- Reviewers have pointed out that this monitor has issues with 10 bit color. ASUS' product website still reports 10-bit color (though it doesn't say "true 10 bit") so maybe there was just a bad batch or something? It'd be a real shame if it were true in general as it would bump this down from a top-of-the-pack 4k killer to merely "pretty good".
- Occasionally there will be a single frame artifact. I'm not sure what's causing it but I suspect it might be the DP cable I'm using. Possible other causes are my video hardware (780 Ti) or some internal problem with the monitor itself. It's relatively infrequent (happening maybe two or three frames per day) so I haven't devoted any time/effort/money to isolating it.
Reviews report that the monitor presents 10 bit support and performs 8 bits with FRC, which basically means the pixels toggle between colors at high speed, so what you actually see is a mixture of two colors (which represents the extra 2 bits of color state). This dithering is pretty noticeable in TN panels which frequently only support 6 bits + FRC (so there's a pretty large gap between the color of the pixels as they toggle, this being one of the primary reasons TN panels are regarded as having poor color quality) but is probably much less visible with 8 bits + FRC.
Pros: - Fast fast fast
- Lots of great reliability features like power-off protection
Cons: - I honestly can't think of anything
Other Thoughts: I have 2 of these set up in RAID1 on my haswell-e build. Posting takes a while, but once it's finished I go from first seeing the windows logo forming to login screen in just a few seconds.
I don't have much in terms of detailed specs yet (I'll post a follow up review with that stuff), but the WEI for this configuration is 7.9 (the max).
Pros: - Easy overclocking
- Easy RAID setup
- GUI uefi interface
- The features are mostly pros
- Lots of useful status LEDs
- The monitor's debug hex codes are in the manual (booklet 2), and the manuals are all posted online
- There is an additional online guide to all of the overclocking settings and what they do
Cons: - Kind of a slow POSTer (10-15s)
- RAID defaults to off, so every time you bork your overclock you have to turn it on again BEFORE trying to boot
- Doesn't seem to honor speed stepping overclocks, I've so far only observed clock speeds at whichever core setting is set lowest
Other Thoughts: I paired this with a 5930k and 32GB of gskill 2400mhz. I've got a stable overclock of 4.5GHz on it (though I might dial it back a bit for power consumption and cooler noise reasons).
I use a pair of intel 730 SSDs in raid 1 as a boot device. I accidentally let it boot once after resetting the CMOS and it booted successfully and damaged the integrity of the RAID. I had to drop the second disk from it (thus degrading the RAID) and re-add it (which re-imaged it from the first disk). It's a bit of a time waster, and without a bit of knowledge of raid safety, I'd have lost the install and needed to reformat. It would be nice if the SATA controller defaulted to RAID mode so that didn't happen.
I know there's a firmware update out for it, maybe that fixes some of the weirdness with the speedstep settings... at this point I'm unable to set a higher overclock for a 1-core load, because such loads still top out at the lowest of the n-core-load settings.
I'll post another review if more information is available.
