HP ZBook G8 2022 experiences problems with display resolution.
I'm working with a brand new HP ZBook G8 15.6 2022 equipped with an Nvidia T1200 graphics card. When I attempt to set the resolution to 1920x1080 instead of the suggested 1600x1050, I encounter black bars on the top and bottom of my external displays. I use three Samsung monitors (S24E650 and two S24C650) connected via DVI cables to a HP G5 dock. Two screens are linked through DVI to DisplayPort adapters, and one is connected via a DVI to HDMI adapter. I've updated the graphics card drivers to the latest version, but when checking the Nvidia control panel, I can only access 3D settings—not display options.

I need to verify my DP bandwidth specifications again. A single DP-alt-mode USB-C port (two lanes) may not support three monitors. Some adapters provide two such ports but will disable USB 3.0 connections. Another option is a 1920x1200 monitor, which should show black bars when pushing 1080p.
The little HP docks seem to rely more on the USB connection than a DP alt mode, acting like a simple display setup. In my experience, the black bars often appear because there are mismatched settings between the monitor resolution and the drive's output. Typically, the display sends a full 1920x1080 signal, but only receives 1200x1080, forcing the device to show black bars. Adjusting these parameters usually involves navigating through Device Manager, which can be tricky to locate.
