Product Snapshot


The Dell U4919DW is the brand’s high-end 49-Inch ultrawide Dual QHD monitor released in 2018. Its wide display, along with a 5120 x 1440 pixels resolution, allows you to multitask seamlessly and play games more enjoyably on a monitor the size of two monitors with accurate colors and no bezels in between your view. It could be considered better than the leading 38-inch monitor. And with decent viewing angles, sturdy build quality, an adjustable stand, and above all a 32:9 aspect ratio, it makes for a great ultrawide QHD monitor for next-level efficiency. However, its competitor, the Samsung C49RG90, comes with a higher refresh rate of 120Hz instead of Dell’s 60Hz at a similar price point.

our Verdict

The Dell U4919DW is a great ultrawide monitor for office users who want to multitask and casual gamers who want a riveting gaming experience. It has a 49 Inch display with good viewing angles and an adjustable stand for added adaptability. The 5120 x 1440 resolution and good color accuracy make working on it enjoyable. Unfortunately, it lacks HDR and G-Sync/Free Sync features. Despite this, the vast display, KVM compatibility, fast-response time, and sound color reproduction make it a great choice for multitasking, but not so much for gamers due to its mediocre gaming performance at its price point.

Reason to Buy

  • Exceptional 5120 x 1440 resolution
  • Good viewing angles
  • Picture-by-Picture KVM switching compatibility.
  • Large screen real-estate
  • Premium build quality

Reason to Avoid

  • It does not support HDR or DCI color
  • No available inputs or output for audio
  • Non-native input lag is very high
