Dell Latitude 3520 -- External Monitors
The laptop has the 11th Gen Core i5-1135G7 processor. There is a USB-C (w alt dp) port and an HDMI port. What resolution monitors is the onboard GPU capable of running if connect both ports to monitors?

@alleyslair The Setup and Specifications information for that system indicate that its HDMI output supports HDMI 1.4, which should allow up to 2560x1440 60 Hz or 4K 30 Hz. The DP revision of the USB-C port's DP Alt Mode isn't specified, but Core 11th Gen CPUs have the Intel Xe GPU, which supports DP 1.4. That would allow setups such as 4K 120 Hz, 5K 60 Hz, and 8K 30 Hz -- without even getting into what might be possible with DisplayPort DSC (Display Stream Compression) if supported by the display. Intel's specs for that CPU here mention 8K 60 Hz as being possible via DP, but that would require either DisplayPort DSC or dual DP 1.4 links to the same display, which you wouldn't be able to achieve from a system with only one USB-C port.
