Im looking to pruchase a USB-C monitor. One has Gen 1, the other has Gen 2. I know the difference between the two is Gen 1's bandwidth is 5Gbps and Gen 2 is 10 Gbps. But in real world, what does that mean when its comes to displaying video? What can the Gen 2 do that Gen 1 can't? can they both display 4k? can they both display 4k HDR? Any difference when its comes to display performance?
