[HDVR-435/835/1635] What should I do if “Out of Resolution” shown in red is displaying in live view of local user interface?

 [HDVR-435/835/1635]When the current resolution of the channel is over the limit, the system will show “Out of Resolution” in red on the screen. Firstly, adjust video settings of the camera with H.264/H.265 compression, 1920 x 1080 resolutions, 25fps, constant bit rate (CBR) and 2048kbps for mainstream. Next, confirm sub-stream of the camera is enabled. The video settings with H.264/H.265 compression, 640 x 480 resolutions, 25fps, CBR and 1024kbps for sub-stream are recommended.
