To share some details, I was fortunate to purchase an AOC 49" LED MONITOR (model AG493UCX) today.
While I have unboxed and assembled the unit, I connected the monitor with the included USB-C cable to my framework laptop. After making an adjustment within the display settings (picture attached AOC-49-Monitor.png), the resolution is reported as 3840 x 1080 @ 120 Hz.
The Framework laptop is using POP!_OS 22.04 LTS with no special drivers (outside the default installation); image attached - Installed_OS-hardware.png.
–Additional testing results below using the same hardware I had disclosed (within this topic/thread as well as the other Expansion Cards that I have purchased).----
Using the StarTech TB3DK2DPPD docking station, I can connect the AOC monitor to the Framework laptop reaching 120 Hz. @apol1o - this monitor is an ultrawide model.
Here is how I preform my testing (but feel free to provide an suggestions):
I was able to reach 5120x1440 via 100.00 Hz with the StarTech dock by connecting the monitor’s provided DisplayPort cable to the dock, then connect the dock to the Framework laptop via the Belkin cable USB-C. As a side note, the options for refresh rate at 5120x1440 were 59.98 Hz, 70.30 Hz, 75.00 Hz, and 100.00 Hz. Note: Connecting the USB-C cable to either Thunderbolt™ 3 USB-C (24-pin) (40Gbps) on the dock achieved the same results. Also this dock does support 5K or 2 4K monitors (1 via DP and 1 via TB3 USB-C port with up to 40 Gbps of throughput)
To reach 120 Hz, I had to change the resolution to 3840x1080. Thereafter any lesser resolution provides the refresh rate choices as 59.98 Hz or 120 Hz.
When I connect the monitor using the DisplayPort Expansion Card (to the laptop), the max resolution is 5120x1440 @ 120.00 Hz (with other options 59.98 Hz, 70.30 Hz, 75.00 Hz, or 100.00 Hz). Technically I can use the Framework Expansion cards to connect both the DisplayPort and USB-C port resulting in the laptop thinking there are two AOC monitors. I will not use the configuration.
When I use the majority of the monitor’s provided cables for DisplayPort, USB upstream cable, and USB-C, the dock will only provide the 5K resolution @ 100.00 Hz. Once I remove the DisplayPort cable from the dock, the monitor will detect the USB-C connection via TB3 at the same resolutions as I reported (3840x1440 @ 120.00 Hz max).
I am happy using the 5K resolution at 100.00 Hz via the DisplayPort.
This configuration allows peripherals (such as keyboard, mouse, jabra conference speaker, headphones, and Logitech WebCam) to be connected to the monitor, the majority of the cables to be connected to the dock, and a single USB-C cable connected to the docking station.
I hope this post was helpful.
I have not tested the OWC USB-C Travel Dock E to see if I can get any resolution at 120 Hz.
