Looking for a 4K Ultra HD monitor with an IPS panel, you may want to consider the Dell UltraSharp 27 4K monitor: U2718Q. It's, actually, a slight upgrade of the P2715Q model that is cheaper but doesn't have HDR support and falls behind when it comes to color accuracy.
I measured the panel thickness, and it appeared to be less than 2 inches thick (1.8 inches). Undoubtedly, this model is a good option to be mounted on the wall.
The borders around the screen are 0.3-inches thick (on all four sides), so there will be a very little gap if you decide to use this monitor for a multi-monitor setup.
The monitor has 27 inches in diameter and measures 24.1 x 7.9 x 21.3 inches in total. The weight makes 13.79 pounds.
The Dell U2718Q specs and the image provided make it a universal model. Generally, the picture is natural and clear enough to be satisfying for those who work with media content or simply for watching movies.
The manufacturer claims that it's an HDR-supported monitor but, in fact, the brightness level is too low (350 nits) to say that you're getting true HDR. So, maybe it uses some simplified version of HDR, but it definitely adds something to the contrast. However, if you are aiming to buy specifically an HDR monitor, it's not the most satisfying option.
Continuing about the contrast, the monitor has an 8M:1 contrast ratio and looks especially good when displaying the text. It has very precise color separation, so I was able to see a lot of details even on pictures that use one color scheme.
In general, the colors require no calibration out of the box except for the black color that looks grayish, but I managed to fix it using color temperature settings as I installed the Dell U2718Q driver.
The monitor has a 5ms response time and a refresh rate of 60Hz which is not variable. Hence, this model will do the job as a basic gaming monitor, but it's far from an advanced one.
For the best possible picture quality, it's recommended to download the Dell U2718Q firmware (from Dell's official website) right after you get the monitor installed.
The overall performance of the monitor can be estimated at 8 from 10.
The monitor is housed in an aluminum-colored cabinet. There are 5 control buttons on its bottom bezel.
Here is a list of the ports available:
Its stand is just a square with a leg in the center that holds the monitor. It's, actually, a standard type of stand used in most Dell monitors. It gives you great flexibility since it's fully adjustable, so you can easily get your perfect viewing position. You even can put it in a vertical position which is very handy for people who make layouts and posters. Besides, you don't need to apply excessive force for adjustment.
The monitor features a convenient, classic Dell design, so it gets 10/10.
The reviewed model supports a 4K resolution and is based on the IPS panel. Thanks to that, the picture looks good with most types of content. The biggest downside of the monitor that I can mark summing up this Dell UltraSharp U2718Q review is bad HDR performance. It also has quite average specs.
