The advantage of buying a professional-grade monitor is color calibrated out of the box. You don’t have to tinker with the RGB setting of your monitor just to get those natural colors.

It would set you back thousands of dollars just to get a hand on those ultra-high-resolution monitors and televisions. Nowadays, the market has now reached equilibrium resulting in reasonably priced 4K monitors.

Similarities between Dell P2715Q and U2718Q 

Before we see how the Dell Ultra HD P2715Q and Dell UltraSharp U2718Q monitors differ, let’s see what their similarities are.

Display Size and Display Technology

The Dell P2715Q and U2718Q are huge monitors with a diagonal viewing size of 27”. The main advantage of a 27” monitor is its size. You can take advantage of that large screen real estate for photo and video editing. Streaming content from YouTube or Netflix is equally impressive due to this humongous screen. Both 27” displays from Dell use the In-Plane Switching technology or IPS for short. This technology is widespread as you can see it in smartphones, laptops, televisions, and of course, monitors. The advantages of using this over other display technology are vivid colors and better viewing angles.

Display Resolution and Refresh Rate

The large screen of the P2715Q and U2718Q is complemented by their 4K resolution (3840 x 2160 pixels). You can multitask better with both monitors since you can open 4 windows side-by-side and still look sharp. These 4K monitors are extra helpful when editing 4K content since you can see the whole 4K content. Moreover, watching ultra-HD content is going to be a great experience on both Dell monitors. Their refresh rate is not that impressive at 60 Hz. It is perfectly reasonable, however, since Dell targets both monitors for content creators and not gamers.


Surprisingly, both the P2715Q and U2718Q have the same set of ports. You have three choices for outputting videos into these monitors. You can either connect via DisplayPort, mini DisplayPort, or the traditional HDMI port. However, both monitors just include DisplayPort to mini DisplayPort cable. So, if you are looking to use this with your laptop, you have to buy an extra HDMI cable. Lastly, both monitors have USB 3.0 ports for your peripherals such as mouse and keyboards.

Differences between Dell P2715Q and U2718Q

Physical Design

One of their striking differences in their physical design is apparent.

Dell Ultra HD P2715Q

Both 4K monitors are released in the same year. However, their design difference made me think that the P2715Q was released first. The reason behind this is its aging design. We are already in the age of disappearing bezels. However, the P2715Q has thicker bezels than I would like in a monitor. Although bezels are thick, it is quite uniform all around.

Dell UltraSharp U2718Q

On the other hand, U2718Q is the definition of a modern monitor. It has ultra-thin bezels. Its grey-colored base can be paired with the Dell XPS laptops. Moreover, this stand has a hole visible even on the front. This hole is for cable management to keep your desktop tidier. If someone said that this monitor was released just recently, I won’t bat an eye because it looks modern. With that said, U2718Q wins by a landslide.

The Winner Is- Dell UltraSharp U2718Q


HDR10 Support

If you are a content creator editing HDR content, having an HDR-capable monitor is a plus. And even if not, HDR10 will get your watching experience to the next level.

Dell Ultra HD P2715Q

Unfortunately, the Dell P2715Q also falls short in this category since it does not support HDR10 content. However, that does not mean that it is a horrible display. It still has the same brightness of 350 cd/m², comparable contrast ratio, and a color-accurate display with a 99.9% coverage of the sRGB gamut.

Dell UltraSharp U2718Q

In contrast, the UltraSharp U2718Q has HDR10 support amplifying your photos and videos color and sharpness. One thing it lacks, however, is a higher brightness. To fully take advantage of the HDR10, you need at least 600 nits (it only has 350 nits of peak brightness). Then again, having support for HDR10 is still better than nothing. Moreover, it also has a factory-calibrated display with 99.9% sRGB coverage and accuracy of Delta-E less than 2.

The Winner Is- Dell UltraSharp U2718Q


Contrast Ratio, Response Time, and Adjustability

Lastly, there are small things that both of these Dell monitors differ such as contrast ratio, response time, and adjustability.

Dell Ultra HD P2715Q

The contrast of the P2715Q is inferior to its competitor at only 1000:1. Thus, blacks aren’t going to be that darker, and shadows lose its details. Response time is also worse with a Grey-to-Grey response time of 9 milliseconds. The response time of 9ms is not that terrible and noticeable anyways. The P2715Q has full adjustability, so you can adjust the height, tilt, and pivot. However, Dell does not mention on its website if it has swivel adjustments.

Dell UltraSharp U2718Q

The Dell UltraSharp U2718Q has overall better specifications. It has a better typical contrast ratio of 1300:1 making blacks as natural as it can be. It also has a faster response time of 5ms which arguably respectable when you use it for gaming. And lastly, it has full adjustability. With that said, there is no doubt that the Dell UltraSharp U2718Q takes this category.

The Winner Is- Dell UltraSharp U2718Q
