Can anyone recommend the best 4K display picture quality SETTING for the 8CH 4K(UHD)PoE NVR (RLK8-800B4) system? I'm looking to purchase a new 4K display monitor and don't want to over pay for a UHD 3840 x 2160 Monitor if QHD 2560 x 1440 Monitor has the better picture quality as many Amazon reviews seem to indicate. Thanks
