Your only using 1440p for desktop use on your 4K monitor
Why ??
I never owned or used a 4K monitor so am I missing some reason why you would no use the monitor 4k resolution for desktop use.

That is as good or better than a lot of Ips monitors, which do you have? And have you run the spyder on it?
Do you have some sort of red/amd desktop image by any chance?

No, because of a bug with bf4 whereby using higher than 125% screen zoom broke the mouse control in the menus, i briefly used 1440P as 125% zoom was perfect for that. I've since gone back to 4K desktop and just moved the monitor closer whilst using 125% zoom.
DGM, calibrated using TFT settings. I will run the Spyder on it at some point and post the results.

The iiyama should have a delta e of around 0.7 going by reviews of similar 4k panels, the DGM 0.4, using the same method
a delta e of less than 1 is considered not visible, it is where the definition of 1 comes from, so either there is a problem with your iiyama (or all iiyama 4k) or you have freakishly super human sight, even a delta e of 2 is considered excellent and not really visible to most people
As an aside the rog is 0.6 de when calibrated, so greg if you are seeing a difference it might be worth calibrating the rog

Just remember that a colorimeter views a small area in the middle of the screen with the sensor facing it directly. Your eyeballs on the other hand are some distance from the screen and are capable of assessing the entire screen area. The bottom and top of the screen subtend different angles and are subject to a colour shift inescapable on Twisted Nematic technology. Analysing colour accuracy in this way and comparing to IPS-type panels is misleading. Which may explain some of the disparity you're seeing in the figures vs. what you're actually seeing in comparison to the IPS. 
I have a detailed subjective assessment of how this all works out in practice on my review of the Samsung U28D590D. As you'll see there is plenty of praise to be had for it and it gives a subjectively decent image, but it isn't immune from the usual TN drawbacks. Drawbacks which a colorimeter can't tell you about.

Couldn't agree more. IPS is a clear step above TN of that i have no doubt and no amount of 'but x and x said this' will change my mind. I can see it with my own eyes. That said, using this Spyder tool has improved it somewhat. The next test will be to run it on the IPS and see what it can do for that.

My DP cables are still causing me all sorts of issues (or the connections or something).
Keep getting flickering and it's getting really annoying!
And even when it's not flickering it's still only running at 60Hz. I'm finding 60Hz almost unusable for gaming. Is this monitor really bad or is this what 60Hz is like?

No flickering here on the same monitor, but am using a certified DP 1.2 cable. This one below.
Flickering usually points to a poor cable or one that is longer than 2M. Here is the list of certified cables. Tick cables and hit search. As you well know, there aren't many certified cables which means there's a lot of junk out there.

I agree, however matt has said nothing about viewing angles, or variation, he's saying the colours as a whole look awful, which isn't the way I would describe it
looking at his spyder report, some of the colours are way off, looking at reviews of the same panel in other monitors that shouldn't be the case
he's got max of 4.52 and plenty of 2.5's, which are way over the max of 1.5 or 1.7 for the Samsung or Asus versions
thanks for posting that matt, I'll be advising people to steer clear of the iiyama in favour of the sammy or asus - will be interesting to see where reviews of the Acer slot in

If you're referring to this samsung one i've seen that one too in person. it's very similar to this monitor only with a non moveable stand. not overlay impressed with either of them truth be told. didn't try the spyder on it mind, but doubt it would have turned it into a world beater. i almost went with the samsung actually, but decided to go with this one due to the better stand and one chip solution for reduced input lag.i just ain't that impressed with tn at all, but when you're gaming at 4k it's less of an issue as games still look good. (even with the drawbacks of tn)
reviews of this monitor are hard to find on google. here's one. I did find two other reviews when i bought it, it was rated the same as the Samsung but can't seem to find them on google now. I actually tweeted TFT to ask them to review it a while back but they declined.

Anybody tried this monitor with Titanfall? I can't seem to get it to open, the game is running in the background but the monitor just goes black and says no signal received (tried with xfire active and disabled). Any ideas?

Yes that samsung, i had one for a few months till i caved and got the rog, tft's review of it shows a max excursion of 1.7, your iiyama 4.5!... no wonder you can see the difference

What's Excursion and what would that do to the image?

If you look at matt's colour report above, you can see where the device has measured each colour and assigned a number to how far it deviates from "true"
Less than 1 is not a visible difference, less than 2 would be considered irrelevant to most people, 4.5 is a very visible difference
It is basically showing that even under ideal conditions matt's iiyama is having serious issues displaying certain shades of blue, brown, some greys and to a lesser extent red
A lot of ips' have issues with blue, and the samsung and asus 4k's are weak on red (1.7 weak), matt's report is showing more than i would expect
For me personally, IPS glow was more of an issue than gamma shift has been on my newer TN's

It seems certified DisplayPort 1.2 cables are very tricky to come by!
Does this mean DisplayPort 1.2A and DisplayPort 1.3 cables will be as hard or harder to come by meaning that if they do release a Freesync 4K monitor we'll have **** all luck ever getting it to work nicely?

There is no such thing as a DP 1.2 cable, DP 1.2A or DP 1.3 cable or a certification programme for such a thing. It's just marketing rubbish for manufacturers to sell things. Only the ports have a 'standard' (or revision).
If a cable is certified officially, carries all the relevant logos and has undergone official testing by VESA then none of that is relevant to its revision. In fact the intermittent flickering issues with these monitors occur no matter how 'great' the DP cable is. That's not the only cause of this flickering.
Obviously a rubbish cable won't help, but a great one won't mean it's plain sailing either. There are plenty of excellent DP cables not listed on the VESA list of certified cables. StarTech make some good ones, for example, that will work just as well as any cable on that list.

I have this monitor and get no flickering with the cable supplied. Flickering where, games or even on desktop etc?
I remember Matt saying to use the 2nd DP port on the back of the monitor rather than port 1. Can't remember why but just thought I'd say for those not tried it. Though I had no issues on port 1 either.
I have my monitors brightness turned down low as I don't like anywhere near stock brightness levels. Even my work monitors are very low so the flat tn look I quite like. IPS is definately much more vibrant but even with my last IPS dell I had it down low on the brightness, especially in the eves when gaming to lessen the strain on my eyes.
I'm enjoying the monitor. Sometimes on boot it will show a max res of 1440p but a reboot soon sorts it and 1440 look a bit fluffy.
Any chance of your settings you used then matt if they are not to laborious and time consuming to post? Thanks muchly.
