I'm using a new re-branded Hik NVR (LTN8704-P4) from milkisbad which is running fairly current and standard Hik firmware. I have a monitor connected directly to the NVR showing the 4 channels. The images seem to be pulling from a substream until I click on a camera for full screen, then it crisps up. Is there a setting I'm missing to get things looking great on the 4-channel view?
