The Dell U3219Q is a good 4k IPS LED monitor with good picture quality. It has great SDR peak brightness, good for most bright rooms, but its contrast ratio and bad local dimming do not make it a good choice for a dim room. The large size and excellent resolution allow you to easily multitask. The U3219Q can display HDR content decently but cannot deliver the creators intent, as it cannot reach the necessary HDR brightness levels and its color volume is limited. It has a low input lag and it is very responsive but only has a maximum 60Hz refresh rate and no VRR to please serious gamers. It has excellent ergonomics and you can easily position it comfortably.
The design of this monitor is very good and resembles the design of most Dell monitors. The U3219Q comes with a sturdy stand that supports the monitor very well. The ergonomics are excellent, despite the size of the monitor, and you will be able to place it to a comfortable position with ease. The build quality is also very good and you should have no issues with this monitor.
The stand looks like the typical Dell stands with the rectangle base and the flat pole that holds the monitor. It is very sturdy, supports the monitor well, and does not allow for much wobbling.
The Dell U3219Q has excellent ergonomics, which is great for this size. You can set it with ease to a comfortable position, and you can swivel, rotate, tilt or adjust the height according to your current needs.
The back of the monitor is plain, which is typical of Dell monitors. There is no texture or grooves and there is provision for cable management through a hole in the stand as you can see here.
The borders of the Dell U3219Q are thin. On the top border, we can see a small groove that serves as a vent that in previous models used to be in the back of the monitor.
The thickness of the monitor when the stand is attached is average within its size category. However, when the stand is removed the monitor is quite thin and will not protrude much if VESA mounted.
The Dell U3219Q has good picture quality. The contrast ratio is decent and among the best for IPS monitors. Unfortunately, blacks are hurt by the poor black uniformity and the bad local dimming. The very good SDR peak brightness, the good reflection handling, and the wide viewing angles make it suitable for working collaboratively in a well-lit office. Performance in HDR mode is decent, however, the color space coverage is good only for normal use. If you are professional in the printing or publishing media, you might be better off looking at other options.
The Dell U3219Q has a decent contrast ratio which is among the best of the IPS monitors we've tested so far and very similar to the Dell 2718Q. The monitor has an option to enhance the uniformity called Uniformity compensation. Unfortunately, when turned on, it hurts the contrast ratio performance as the monitor can only achieve a contrast ratio of 817:1. This is why we recommend that you leave it deactivated.
The U3219Q does have a local dimming feature, but it is only active in HDR, and does not have any significant impact on the contrast ratio.
The Dell U3219Q supports local dimming only in its HDR modes. The HDR mode in which local dimming is more effective is called 'HDR reference'. In the other modes, local dimming is very subtle. The reference video was filmed in the 'HDR reference' mode, and you can see that the performance is bad. As the bright object traverses the screen, you can observe the wide vertical blooming bands that follow its movement. At times, these bands get stuck and turn off (fade out) only after a few seconds. This is one of the worst local dimming implementations we have seen so far. If you find that it bothers you, then change it to a different HDR picture mode.
The brightness is great. It can get bright enough for most bright rooms and the brightness remains constant regardless of the size of the illuminated area on the screen. This result is in line with the Dell U2515H.
HDR mode: Standard - HDR reference
Decent HDR brightness for the Dell U3219Q. Brightness remains relatively constant across window sizes except when the monitor is displaying small highlights where it experiences a small drop. Unfortunately, the brightness level is not enough to deliver the creators intent when watching HDR movies. If you are looking for a monitor with better HDR performance check out the Acer Predator X27.
The Dell U3219Q has decent horizontal viewing angles. Just like the Dell U2718Q, black levels remain good no matter the angle at which you look at the monitor, whereas brightness fades and colors lose accuracy as angles approach 40 degrees.
Great vertical viewing angles on the Dell U3219Q. The image remains quite accurate within the first 25 degrees. At larger angles, colors start to shift and then a decline in brightness becomes more apparent. Fortunately, the monitor's ergonomics have a good tilt range that allows you to adjust its position to minimize potential vertical viewing angle issues.
The gray uniformity of the Dell U3219Q is excellent. The 50% test picture displays some slight uniformity issues at the sides that appear a little darker. However, these issues are minor and hardly noticeable in normal use. There is very little noticeable dirty screen effect, and this is great for browsing the web or viewing videos.
In the 5% gray test uniformity picture, it is very hard to spot any uniformity issues or any dirty screen effect. This means that dark scenes will be free from clouding just like the Dell U2515H.
The monitor has a Uniformity compensation option that we recommend leaving deactivated as explained in the contrast box of this review.
The Dell U3219Q has disappointing black uniformity. Clouding is visible all over the image and there is some backlight bleed on the top edge. This is a similar result to the Dell Alienware AW3418DW and the Samsung CF391.
The out of the box accuracy of the Dell U3219Q is great. The 'Standard' Picture mode is the most accurate one.
The white balance and color dE are both under our threshold of 3, and thus most people will not notice any inaccuracies. The color temperature is slightly warm, and the gamma is following the target curve very closely and thus scenes are displayed at the right brightness.
After calibration the color accuracy of the Dell U3219Q is excellent. We set the Picture mode to 'Custom Color' as this mode gave us full control on the internal RGB controls. The color temperature was adjusted closer to the desired 6500 K, and both the white balance dE and the color dE are further diminished to levels that make it very difficult to notice inaccuracies. Finally, the gamma continues to follow the target curve closely except in the very high luminosities where the image is slightly brighter than expected.
You can download our ICC profile calibration here. This is provided for reference only and should not be used, as the calibration values vary per individual unit even for the same model due to manufacturing tolerances.
s.RGB Picture Mode: Custom Color (calibrated)
Adobe RGB Picture Mode: Custom Color
The Dell U3219Q has an excellent SDR color gamut. The coverage of the standard s.RGB gamut which is used by most is nearly perfect. However, the coverage of the Adobe RGB color gamut that is used by professionals in print and media is limited. If you are looking for an excellent Adobe RGB coverage, check out the Acer Predator X27.
s.RGB Picture Mode: Custom Color
Adobe RGB Picture Mode: Custom Color
Excellent color volume. The Dell U3219Q can display a great number of colors in various levels of luminance. Unfortunately, it cannot display the dark shades well due to the not so great contrast ratio.
DCI P3 Picture Mode: Standard - HDR reference
Rec. 2020 Picture Mode: Standard - HDR reference
The Dell U3219Q has a decent HDR color gamut and can display rich, saturated colors when in HDR mode. HDR is supported both via HDMI and DisplayPort.
DCI P3 Picture Mode: Standard - HDR reference Rec. 2020 Picture Mode: Standard - HDR reference
Decent HDR color volume. The lack of high contrast ratio limits the color volume, especially in the dark shades of colors.
There is no temporary image retention present on the IPS panel of the Dell U3219Q even after our 10-minute high contrast torture test.
Great performance for the Dell U3219Q on our gradient test as there is no significant banding in any color or shade.
When displaying large bands of a single color no color bleed issues can be seen.
The reflections handling of the Dell U3219Q is decent and very similar to the Dell U2718Q. It has a very light-matte finish which only somewhat diffuses the reflection across the screen. Overall, it should be fine for an average-lit room, but some might find reflections a bit distracting in a bright room.
The Dell U3219Q monitor has decent motion handling. It has a fast pixel response time that displays fast motion with little blur. Unfortunately, this monitor is not flicker-free, and this might bother some people. Finally, the monitor supports a refresh rate up to 60Hz and does not have any implementation for variable refresh rate that would please gamers.
Very good pixel response time, great for playing video games with fast-moving content or for watching sports on your monitor. In our test, there is just a short blur trailing the moving logo, and this is great. The best results were obtained with the 'Response Time Normal' setting which was fast and did not cause as much overshooting as the one observed in the 'Response Time Fast' mode. For that reason, we recommend selecting the 'Response Time Normal' setting. Overall, the response time is very similar to other IPS Dell monitors like the U2717D or the U3417W. If you are looking for a faster response time for gaming check out the Acer Predator XB271HU.
Unfortunately, this Dell monitor is not flicker-free. There is a very high-frequency flicker, as well as a 200Hz wobble. The high-frequency flicker isn't noticeable, but the 200Hz wobble can be noticed on our moving RTINGS logo pattern when the backlight is turned down. If you find that flicker is bothering you then set the backlight to 100% where there is no noticeable flicker.
Just like the Dell U3417W, the U3219Q has the very common native refresh rate of 60 Hz. There is no variable refresh rate feature like FreeSync or G-Sync, and while this might not be an issue to most users, those who enjoy competitive gaming might find it limiting.
The Dell U3219Q has excellent low input lag, at all input resolutions. The large screen and the excellent 3840x2160 resolution is great for multitasking. There is an abundance of inputs, and you will be able to connect the most recent devices to it without issue. The monitor also provides the option to use it as a USB hub.
Lowest input lag possible at the center of the screen, when the monitor is displaying an alternative resolution at its native refresh rate. The non-native resolution tested depends on the native resolution of the monitor, following this pattern unless otherwise specified in the Input Lag text:
|Native Resolution||Non-Native Resolution Tested|
Excellent low input lag regardless of resolution, good enough for serious gaming. The input lag remains very low when in HDR mode.
This is a large monitor with ample resolution to allow you to see more of your work. It is very good for those who wish to multitask or those who wish to use it for watching 4k movies.
The Dell Ultrasharp U3219Q can be used as a USB hub. The USB ports can be left powered on when the monitor is off. Two of the ports support BC1.2 fast charging, with a maximum capacity of 2A.
The monitor supports HDR but does not have any other additional features or internal speakers.
The Dell U3219Q supports HDR both via HDMI and via DisplayPort. This is an enhancement compared to the Dell U2718Q which only supported HDMI.
We tested the Dell U3219Q monitor which is part of the Ultrasharp series.

The LG 32UD99 is somewhat better than the Dell U3219Q. The LG 32UD99 is flicker-free and has a better black uniformity, which is great for dark scenes. Also, the LG 32UD99 supports FreeSync, which is great if you are a gamer. The Dell U3219Q, on the other hand, has much better ergonomics that allow you to place it comfortably with ease.
The LG 32UL950 is slightly better than the Dell U3219Q. Both deliver very similar overall picture quality, but the 32UL950 supports FreeSync, which is great for gaming, and has more inputs. The U3219Q has better ergonomics, making it slightly more versatile.
The Dell U3219Q is better than the BenQ EW3270U for most people. If you care more about dark scene performance, then the BenQ EW3270U is a better choice as it has better contrast and better black uniformity. The BenQ EW3270U is also flicker-free. On the other hand, the Dell U3219Q has much better ergonomics, so you can place it comfortably and much better viewing angles so that the image remains accurate when you view it from the side.
The Dell U3219Q is marginally better than the Dell Alienware AW3418DW. The Dell U3219Q has a significantly better ergonomics and supports HDR content. The Dell U3219Q also has a better resolution so you can see more of your work on your screen. The Alienware is flicker-free, handles reflections better, and has a lower input lag and support for G-SYNC, which is great for gaming.
The Dell U3219Q is better than the Dell U3417W. The Dell U3219Q has lower input lag which is great for gaming and if you want you can rotate it to portrait.
