The Dell Ultrasharp U4919DW is a good 49" IPS monitor with wide viewing angles, and an excellent Dual QHD resolution. The high native resolution is excellent for multitasking, and offers a more immersive gaming experience, and like many Dell monitors, it has great accuracy out of the box. Unfortunately, it is limited to a 60 Hz refresh rate, and it doesn't look as good in a dark room. When displaying non-native resolutions, the input lag is very high, which is disappointing.

Pros
  • Lots of screen real-estate, great for multitasking
  • Image remains accurate when viewed at an angle
  • Excellent out of the box accuracy
Cons
  • High non-native input lag
  • Mediocre dark room performance

Curve radius : 3800R
Weight (without stand)
:
24.7 lbs (11.2 kg)
Weight (with stand)
:
36.8 lbs (16.7 kg)

The design of the Dell Ultrasharp 49 is very similar to the Dell U3818DW, but with a wide aspect ratio. The stand is solid and supports the monitor well, and it has a good height and tilt adjustment, but it can't swivel. Like most Dell monitors, the U4919DW has great build quality and shouldn't cause any issues. The overall design is very clean and professional, and looks great in any setting.

Stand
Width
:
15.0" (38.1 cm)
Depth
:
13.8" (35.1 cm)

The stand is well built, solid, and doesn't take up too much space. It is quite thin, so you can still place small objects on it. Given the size of the monitor, it still wobbles a bit, but this isn't too distracting.

4.2 Ergonomics
Height Adjustment
:
3.6" (9.1 cm)
Switch portrait/landscape : No
Swivel Range : N/A
Tilt Range : -20° to 5°

The U4919DW has a mediocre height adjustment, but a great tilt range, so it is easy to place it in a comfortable viewing position. Unfortunately, it doesn't swivel, and naturally it can't rotate to a portrait orientation.

Back
Wall Mount : VESA 100x100

Like the majority of Dell monitors, the back is plain, with no extra design flair, and no bias lighting feature. There is only basic cable management, but it is good enough to keep your desk free from cable clutter.

Borders
Borders
:
0.4" (1.0 cm)

The borders are quite thin compared to the overall size of the monitor, and there is no noticeable gap between the borders and the first pixels.

Thickness
Thickness (with stand)
:
8.1" (20.6 cm)
Thickness (without stand)
:
4.1" (10.4 cm)

Due to the large size and gentle curve, the U4919DW is quite thick. The stand leans back a bit, but the base can still be placed flush with the wall behind it.

8.0 Build Quality

The Dell U4919DW has great build quality, very similar to the Dell U3818DW. The stand is very solid and well built, and you shouldn't have any issues with it.

7.0

Picture Quality

The Dell Ultrasharp U4919DW delivers decent overall picture quality, similar to the Samsung CHG90 and Dell U3818DW. Like the Dell U3818DW, it has mediocre native contrast and disappointing black uniformity. It is brighter than the U3818DW, but has a slightly worse color gamut, and slightly worse viewing angles. Out of the box, the monitor has great accuracy, and the few minor imperfections are easily corrected with a few changes.

6.3 Contrast
Native Contrast

The Dell U4919DW has a mediocre native contrast ratio, much worse than the CHG90. Blacks look gray in a dark room, similar to the U3818DW. There is a uniformity feature that can be enabled to improve overall screen uniformity; when activated, the contrast ratio drops to 690:1. Unfortunately, there is no local dimming feature to improve the contrast ratio.

The Dell Ultrasharp U4919DW has great gray uniformity, with very little dirty screen effect, which is great. There is a uniformity feature that can be enabled from the monitor's internal menus; we found that it doesn't improve the uniformity much, but causes a significant decrease in native contrast and brightness, so we don't recommend using it.

5.8 Black Uniformity

The monitor has disappointing black uniformity, similar to the U3818DW. There isn't much noticeable flashlighting, which is good, but there are bright bands across most of the screen.

The monitor has great accuracy out of the box. Both color and white balance dE are low enough that most people won't notice any inaccuracies. Gamma does not completely follow the target sRGB curve, and the color temperature is a bit cool. The 'Standard' Picture Mode is the most accurate out of the box, but does not allow you to adjust the RGB controls.

8.0 Reflections

The Dell U4919DW has great reflections handling. The curved screen tends to distort reflections a bit, which can be distracting in some occasions, but overall there shouldn't be any issues.

7.1

Motion

The Dell U4919DW has decent motion handling. It has a great response time, with little overshoot and only a minor blur trail. It does not have the motion smearing issues seen on the U3818DW. The backlight is completely flicker-free, which is great. Unfortunately, the standard 60 Hz refresh rate may disappoint some, and it does not support any variable refresh rate technologies like FreeSync or G-SYNC.

Response Time Normal
Response Time Fast

The Dell U4919DW has a great response time, and the blur trail behind moving objects is very short. There are two selectable overdrive settings: 'Normal' and 'Fast'. We recommend the 'Normal' setting, as 'Fast' has more overshoot but isn't much faster. In either mode the overshoot is relatively minor, and shouldn't cause any issues. This is much better than the U3818DW, which had noticeable motion smearing.

8.9

Inputs

The monitor has excellent low input lag when displaying its native resolution. The large screen and excellent Dual QHD resolution are excellent for multitasking, and it has a good assortment of inputs for recent devices, including USB-C with an excellent 90W power delivery mode.

The Dell U4919DW has excellent low input lag when displaying at its native resolution of 5120x1440. Unfortunately, when the monitor is sent a non-native resolution the input lag is very high.

9.3 Resolution and Size
Native Resolution : 5120x1440
Aspect Ratio : 32:9
Megapixels : 7.4 MP
Pixel Density : 109 PPI
Screen Diagonal : 48.8 inches
Screen Area : 623 sq inches

The monitor has an outstanding native resolution of 5120x1440, which is the equivalent of two 1440p monitors placed side-by-side. This provides a huge amount of screen real-estate to work with, and is excellent for multitasking.

We have received multiple reports of Mac users being unable to select the full native resolution on the U4919DW. It appears to be a limitation with some Apple hardware.

The Dell Ultrasharp 49 has a good selection of inputs, including two HDMI 2.0 ports, one DP port, and one USB-C port. The USB-C port supports DP Alt Mode, and DP power delivery with a maximum power delivery of 90 W, so you can easily keep your laptop charged while working, with only one cable.

Features

The Dell Ultrasharp 49 has very few additional features. Like the U3818DW, it has a unique set of connections and a picture-by-picture mode that allows you to use the monitor with two computers at once, with only one keyboard and mouse. There is also a Uniformity Compensation mode that is supposed to improve gray uniformity, but in practice doesn't improve uniformity much, and instead reduces the contrast and brightness.

The Dell U4919DW has a few extra features, including:

  • Picture-by-Picture: You can display the input from two sources at once. With the included KVM functionality, this allows you to work on two computers at once, with only one keyboard and mouse.
  • Uniformity Compensation: A factory calibrated mode that is supposed to correct for any uniformity issues. As the U4919DW already has great uniformity, this mode doesn't improve uniformity in any significant way, but causes a reduction in brightness and native contrast.
