Dell 5K UltraSharp 40 Curved Thunderbolt

Dell is out the gate early with one of its CES announcements this year. Joining its UltraSharp Monitor lineup is the new 40-inch 5K Curved Thunderbolt Hub Monitor. Here are all the details on this big boy.


Update 3/1/24: This new monitor is available now direct from Dell priced at $1,920 ($480 off at launch). Our original coverage follows.


Shared with 9to5Mac, Dell announced all the details for the upcoming new UltraSharp Monitor (model U4025QW) in a press release.

This could be a compelling option for creatives and other professionals who want a large display without giving up a high resolution. There’s also a solid Thunderbolt 4 hub built-in for great connectivity. And there’s support for the MacBook Pro ProMotion 120Hz refresh rates.

One note, this soon-to-be-released 40-inch curved monitor isn’t a full 5120 x 2880 5K resolution like Apple’s Studio Display – it features a 5120 x 2160 resolution (5K horizontal 2K vertical).

Here’s a look at the ports on the back:

There’s also a new UltraSharp 34 Curved Thunderbolt Hub Monitor that’s arriving at the same time in February. It’s going to be priced at $1,399.99, however, it sports a lower 3440 x 1440 resolution (not even 4K).

Here are the two new UltraSharp monitors side-by-side:

9to5Mac’s take

There are quite a few impressive features on the 40-inch UltraSharp Thunderbolt Hub Monitor like 120Hz refresh support, 140W power delivery for even the most power-hungry MacBooks and other laptops, 2.5Gb Ethernet port along with a generous Thunderbolt hub.

A couple of compromises include no webcam, plastic build, and the 5120 x 2160 5K resolution that’s below the full 5K spec of 5120 x 2880. However, it is a better resolution than most 40+ inch monitors out there including Dell’s own 43 and 49-inch UltraSharp Monitors.

For everything you’re getting at this size, $2,400 seems reasonable. But you’re paying a premium for the curved screen, 120Hz refresh, and Thunderbolt hub. For example, Dell’s 43-inch UltraSharp is $1,400 less which features a flat 4K display and USB-C.
