It would be great if TekSyndicate tested the following 40" UHD monitor:
Looks like a good contender to the Korean 40" monitors, without the headaches with customs, shipping and warranty.
I own a 27 inch Iiyama monitor. They are pretty no frills simple design and good. Pretty much what people want out tof a monitor. Stylish, thin bezel and all round good monitor.
I would like to see the 40 inch one but it risks at this stage being a me too review, unless it has some cool Unique Selling Point, like working free sync?
Jay of two cents fame has a monitor from some brand unknown to me, they seem to be a new peripheral maker, but then monitor is high refresh, freesync and crucially the free sync works over a very wide range, none of this 45 to 70 hz nonsense. That I would like to see.
I looked in the specs on this monitor and don't see anywhere if it has HDMI 2.0 with HDCP 2.2, or if it supports Chroma subsampling 4:4:4. I talked to the U.S. dealer for liyama and he is asking his contacts if this monitor meets those specs. Will post when I find out.

Looks like it has at least 1 HDMI2 from the Tech Specs as it can do 3840 x 2160 at 60hz.
Native resolution: 4K 3840 x 2160 ( 8.3 megapixel)
Resolutions: VGA (max. 2048 x 1152 @60Hz), HDMI1 (max. 3840 x 2160 @60Hz), HDMI2 (max. 3840 x 2160 @30Hz, 1920 x 2160 @60Hz, 1920 x 2160 @60Hz), HDMI2/MHL (max. 1920 x 1080 @60Hz), HDMI3 (max. 3840 x 2160 @30Hz, 2560 x 1440 @60Hz, 1920 x 2160 @60Hz)
Vertical sync 24 - 75 Hz (looks like it has Freesync)
Maximum resolution VGA: 2048 x 1152 @60Hz, HDMI: 3840 x 2160 @60Hz, DisplayPort 3840 x 2160 @60Hz ( 8.3 megapixel)
I found a quite extensive test from the Netherlands:

TLDR:
+ Contrast
+ Brightness
+ Price
+ 4K 60 Hz DP & HDMI
- Oversaturated colors with few adjustment possible
Target:
. Gamers
. People with limited budget
Wrong audience
Graphic / Photo professionals for whom colour accuracy is critical
I'm so hesitating to purchase it, as I would have to keep my Dell 27" for Photo & graphics.
From official site:
Synchronization: Separate Sync
What could that mean?
There is also another Iiyama model called PROLITE LE4041UHS-B1
The only difference I can see is that it has no stand, only vesa mount.
Edit:
From manual:
Input Sync Signal: Separate sync: TTL, Positive or Negative
Looks pretty promising although not quite as cheap as the other Korean 4k. At $917.00 USD I'd say it's a bit too pricey for me to jump on right now. Also, I can't seem to find one that I could buy even if I wanted to from Canada.
I heard back from the U.S. rep and he did get confirmation with the engineering dept that the monitor does indeed do Chroma 4:4:4 along with having HDMI 2.0 that is HDCP 2.2 compliant.

Yeah Iiyama will sell different versions of the same monitor some time but with better stands or other stand options.
Hexus did a short take http://hexus.net/tech/reviews/monitors/90008-iiyama-prolite-x4071uhsu-b1/
The review could have been more detailed
Interesting.
I'll contact them because their testing of color accuracy is totally different than that of nl.hardware.info
I finally bought the monitor for 492 € + taxes.
Just installed it, so far everything seems fine, I'll give more details in a few days.
First impressions are very positive.
Yes, there is vignetting on the borders, which seems universal on 40" displays, but so far it hasn't gotten on my nerves.
Here are the parameters I used to calibrate my monitor to 120 cd/m2, 6500K, Gamma 2.2:
Brightness 31
Contrast 56
Red 100
Green 89
Blue 79
Here is the corresponding ICC profile done with GMB:
Iiyama_120cdm2_31-56_100-89_79_12-02-2016_2.icc
On Windows, you have to save it under:
C:\Windows\System32\spool\drivers\color
Follow the steps in this link, including for gamma:
Using ICC profiles with Windows
Yes, I am aware that profiles and settings are individual to each and every monitor.
However, in my experience, others' settings and profiles are good starting points, and better than nothing.
This weekend, I'll create additional ICC profiles with a higher luminosity target, probably 140 or 160 cd/m2, which may be more enjoyable for games & movies.
BTW, I've just seen my first 4K/60fps videos from Jacob + Katie Schwarz on YouTube: Wow.
I would be very interested in a comparison between this monitor and the amh a409u.
For me, as I understand it, the amh a409u would cost 672.23€ incl. 19% VAT (564.90€ + 107.33€ VAT = 672.23€)
I can get the ProLite X4071UHSU-B1 for 594.99€ incl Tax.
In terms of specs, they seem very similar. My current main monitor is also a iiyama and i´m pretty happy with it, but since the "established brands" seem to be worse in a lot of cases than these korean ones when it comes to 4k 40", I just don´t know.
IMHO the iiyama it is way better than the AMH A409U, at least v1: build quality, look, stand, no color bleeding that I could detect so far.
Can't do a purely graphical comparison though.
Also for me no uncertainty with eBay and no potential customs problem.
Perfection at this size probably won't happen until OLED (light uniformity) but so far I'm quite satisfied, working with 4 apps displayed or playing WoW. Videos are outstanding on this monitor, especially 4K / 4K 60 Hz videos from YouTube / Vimeo.
How is the latency in games? Is it better than the A409U. According to Wendell, that one had about a 60ms lag.
I got myself one of these monitors now.
I havent done much testing, but this is what I can tell you guys so far:
firstly, the factory settings for color are totally acceptable, it has very good contrast for all colors.
secondly, I was able to get it running at 67Hz at DP 1.2 on my 280x, however this means you cant have 10bit colors.
How's the flickering at brightness set to 31?
Because this monitor has 480Hz PWM instead of the 240Hz PWM of the Philips 40".
This is interesting:
The Iiyama also has a different panel than Philip's 40" monitor. The panel has Dolby Vision (Rec.2020) colour space, but it doesn't have the Dolby Vision HDR backend. Both were confirmed by email by a technician from Iiyama's tech department.: https://hardforum.com/threads/iiyama-prolite-x4071uhsu-b1.1883040/#post-1042081558
Sorry I have nothing to measure latency in games.
I mostly play WoW and do not see significant lag at 4K on my GTX970, but then again, WoW isn't a FPS.

I don't see any flickering.
This is my first 40 " 4K monitor so I have little to compare it.
Clearly, the lighting isn't as uniform as on my Dell 2713HM, which was a graphics monitor (100 % sRGB).
An d the vignetting on the sides is clearly visible.
These are the 2 big compromises that seem to be widespread in the present generations of 4K 40" monitor. And to me, almost not irritating as one get used to it.
Other than that, so far after 1 month of daily 8h+ usage, I'm totally satisfied, I don't think I could expect much more in the price/performance nowadays. I've begun to adapt working with 3 or 4 apps on the same monitor, and I use my second monitor much less than before.
Of course, there are lots of opportunity for improvements. First no more vignetting then better uniformity or OLED whenever it'll become affordable, compatibility with G-Sybc/Freesync, ...
I don't think 40" 4K monitors will become the norm anytime soon, all the more so that 4K content is so limited. But some users will definitely appreciate them.
