Only rarely have I heard of "Monitor Drivers'.
Usually only monitors with some "new"(at the time they were made) feature or an especially odd feature set ever needed drivers.
GPUs (graphic processors) whether they be on a video card or built in to the CPU require drivers and it is ALWAYS best to use the GPU drivers from the manufacturer website (AMD for AMD GPU, NVidia for NVidia GPU)
Any "apps" or "drivers" that come with a monitor are 99.9% of the time just bloat-ware.
