Review on 🔌 HDMI to VGA DVI HDMI 4-in-1 Converter Adapter Cable with 3.5mm Audio & Micro USB - Compatible with HDMI Laptops, Computers, and More - Simultaneous Connections by John Hashman

Use HDMI TV and DVI Monitor. Installation was easy and the results (image quality) were excellent. Good deal for the money I thought. Then I turned off the monitor. The image on the television repeated itself; 1 sec on/1 sec off switched off. The monitor that was switched on is switched on again. Everything is all right again. Now turn off the TV. The image on the monitor is not cyclic, but shows horizontal interference, sometimes minimal, sometimes thick. Turned the TV back on. Everything is all right again. I liked the all-on result, but my use case is to NOT have both displays on all the time. I'll come back and look for something more reliable.
