I having problems with an NVR (from AliExpress. Yes I know it’s cheap): 8CH CCTV H.265 NVR Board 4K/5MP/4MP HI3798M Security NVR Module 4CH 5MP / 8CH 4MP XMEYE P2P Mobile Monitoring Cloud Viewing-in Surveillance Video Recorder from Security & Protection on Aliexpress.com | Alibaba Group The problem is that the monitor don’t get any signal or the video signal is distorted. I have tried multiple of things: - bought an more powerfully power adapter 6A - tried another HDMI monitor/TV - disconnecting al other peripherals like HD, USB - reset device NVR is connected with HDMI to DVI connector on monitor. If I lower the resolution to eg 1280x1024 I get the following signal. YouTube video: If I set resolution higher like 1920x1080 I don’t get signal and monitor goes in sleep mode. NVR has an option to display in 4K but can’t use this. Any thoughts?
