Review on 📺 J-Tech Digital JTD0102/4K 2-Port HDMI Splitter - Ultra HD 4K 3840 x 2160 Resolution & 3D Support by Dale Hing

The only complaint I have is that the picture flickers during power surges, e.g. B. in the case of lightning strikes nearby. I hooked it up to a good quality backup battery and computers, TVs and other electronics stay on, but the associated screens flicker each time and then a few seconds of darkness to reset them. Apart from that everything is alright. I tried 3 other brands and sent them all back because they just didn't work or broke completely after a few weeks. It's been 6 weeks and this one is still going strong. During installation, I followed the excellent "TR" browser instructions and turned off the monitors and my CCTV system (or other input devices), then connected the HDMI cables, then plugged in and turned on the device, then turned on the monitors and it worked on the first try
