Acer ConceptD CM3 CM3271K bmiipruzx 27" UHD 4K 3840 x 2160 IPS Radeon FreeSync Monitor, Pantone Validated, DisplayHDR400, 99% Adobe RGB, Delta E<2 (Display Port, 2 x HDMI, USB Type-C & USB Ports)

This is a stunning display. Build quality is solid, the included hood and cables are great and calibration shows that the numbers deliver. Great price point.

4K 27” model… With a lot of new monitor tech on the horizon, this is one of the better high-end-like displays I was able to find for the price. If money is tight, you can likely do better with something in the $400 range, but if you’re spending out of pocket and ok with the risk of some apparent occasional manufacture defects this panel punches nicely above its weight class and should be classed with $800-1200 screens.With that in mind there are some corners cut here for the price. Configurations for HDR and color need some massive tweaking out of the box. The type c port isn’t thunderbolt, but it does carry plenty of charging power for most laptops and DP signal fine - along with an okay USB hub (I’ve had some power complaints from different computers for different layouts but it’s been reliable enough for a home desktop). It also has basic sync and works okay for basic gaming without smearing all over the screen. If you want to competitive FPS, you’d be better off with a 1-2k monitor instead.I use it mostly for code, terminal, and a bit of media making. For all of this, it has been excellent. It works with my Mac, a windows gaming laptop, and various Linux boxes. HDR was super washed out at first but some tweaking in the OSD fixed this. It is honestly the first 4K monitor I’ve been pretty happy with. I was going to go with a dell, but they were sold out. The MacBook display spoiled me, and since I haven’t been gaming any more I wanted some extra pixel density. This should hold me over a couple years until new HDMI and TB standards become more common, I hope.

The monitor is not working properly (there is a dark streak on the right side). It's still under warranty. I contacted them a week ago about it, and I've been assured every day that someone from the "higher department" (their words) will contact me about replacing or repairing the monitor. The people I've spoken with said "you're just going to have to wait." I've already waited a week.

Great color. The 3-sided hood/shield is also a very nice extra feature.

Look no further.
