9C9B6UA Which thunderbolt dock for highest external display resolution?

[lasitter]

I think this describes my laptop:

HP Spectre x360 2-in-1 Laptop 16, Windows 11 Pro, 16", Touch screen, Intel® Core™ Ultra 7, 16GB RAM, 2TB SSD, NVIDIA® GeForce RTX™ 4050, 2.8K, Nightfall black

I have an old external display now, but I'd like to upgrade it to whatever the laptop can output thru its external video or USB-C ports. Is thunderbolt the best option? And the display?

Current display is a Dell U3011 with a max resolution of 2560x1600

Right now I'm just doing HDMI->DVI and I'm not getting the highest resolution (2560x1600) that the Dell U3011 can provide. What kind of dock do I need just to achieve that resolution?

That is a very tricky one depending on the version of your HDMI cable you may only get 1920 x 1080 resolution. You need a very expensive TB4 dock or simply use USB-C to DP monitor.

So, even though the monitor also has a display port on it, a USB-C to Display Port cable might not be enough? Monitor might be too old?
