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.
Our Verdict
The Dell U4919DW is a good monitor for most uses. It has great wide viewing angles, good peak brightness, and an excellent color gamut. Unfortunately, it doesn't look as good in a dark room, and gamers may be disappointed by the 60 Hz refresh rate, and lack of variable refresh rate.
- Lots of screen real-estate, great for multitasking
- Image remains accurate when viewed at an angle
- Excellent out of the box accuracy
- High non-native input lag
- Mediocre dark room performance
This is a great monitor for office use. It has wide viewing angles, and the high resolution, large screen is excellent for multitasking. Like the U3818DW, it allows you to work on two computers at once, great if you have a work and personal computer.
Overall, the U4919D is a good monitor for gaming. It has a great response time and low input lag at the native resolution, but the 60 Hz refresh rate may disappoint more serious gamers, and it doesn't support any variable refresh rate technologies.
Decent monitor for multimedia. The high resolution 32:9 screen is great for watching movies, and it has a fast response time, with little blur trail behind fast moving objects. Unfortunately, it doesn't look as good in a dark room.
Decent monitor for media creation. The large, wide format screen allows you to see more of your project at once. It also has excellent wide viewing angles, great for sharing your work with a nearby colleague.
The Dell U4919DW does not support HDR. For a decent HDR monitor, check out the Samsung CHG90.

We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
