Can HP EliteBook 840 G7 Notebook drive a 5k2k display?

My employer provides my with a HP EliteBook 840 G7 Notebook. I'd like to buy a external monitor for it, and I came across the Dell UltraSharp 40 Curved WUHD Monitor - U4021QW. I'm somewhat confused by the HP description of the laptops capability of running a 5k2k monitor like the Dell:

1. On Page two of the QuickSpecs, it says under point 4 and 5 "SuperSpeed USB Type-C® 5Gbps signaling rate ® with ThunderboltTM". I thought Thunderbolt is always 40Gbit/s? Why would Dell mention "5Gbps"?
2. On Page seven of the QuickSpecs, it says the laptop can drive a single 5k Display at 60Hz, when a HP USB-C Universal Dock G2 is used. Can I use a third-party thunderbolt dock (e.g. OWC Thunderbolt 3 Docking Station) to run the Dell UltraSharp 40 Curved WUHD Monitor - U4021QW, or is laptop only capable of running a 5k display with the Dell specific dock?

Solution 1:

Probably not for a long time w/o cooking eggs :) , based on your model you've specified HP EliteBook 840 G7 Notebook and looking at the detailed technical specifications You'll see the graphics are integrated Intel UHD Graphics w/ every CPU combination.So w/out providing your specific CPU combination we can't determine what Intel UHD Graphics chipset was shipped w/ your laptop.

Maybe you got the cheapest Intel processor for the model in question

-Intel Core i5-10210U Processor, which is a 10th Gen Intel Processor that shows:

• 4K Support - Yes, at 60Hz Max Resolution (HDMI)‡ 4096 x 2304@24Hz
• Max Resolution (DP)‡ 4096 x 2304@60Hz
• Max Resolution (eDP -Integrated Flat Panel)‡ 4096 x 2304@60Hz

Or maybe you got the most expensive Intel processor for the model in question

-Intel Core i7-10810U Processor, which is a 10th Gen Intel Processor that shows:

• 4K Support - Yes, at 60Hz Max Resolution (HDMI)‡ 4096 x 2304@24Hz
• Max Resolution (DP)‡ 4096 x 2304@60Hz
• Max Resolution (eDP -Integrated Flat Panel)‡ 4096 x 2304@60Hz

But lo and behold they're the same spec...

If you got the latest 11th Gen Intel Intel® Core™ i7-11850HE now your graphics specs w/an integrated driver are:

• Max Resolution (HDMI)‡ 4096x2304@60Hz
• Max Resolution (DP)‡ 7680x4320@60Hz
• Max Resolution (eDP - Integrated Flat Panel)‡ 4096x2304@60Hz

The monitor in question: Dell UltraSharp 40 Curved WUHD Monitor - U4021QW Tech Specs:

• Native Resolution - 5120 x 2160 at 60Hz

Take look at page 18 of the Users Guide will answer all your questions about the speeds/data transfers. But you may have to update to the latest Intel driver Page 76 has points of why it may or may not display. I would definitely recommend going w/ a dock to avoid overworking your laptop but a dock w/ some type of integrated graphics and that you have vetted the Graphics Chip set is capable of driving that sweet monitor.
