I bought 2x of this product to connect 1) my PC (Gigabyte GeForce RTX 3060 graphics card) + notebook to the same monitor (Samsung UR28R55) and 2) my PC + PS4 to the TV (LG Oled), and it does not work. I have tried all the configurations, and noticed that the switch does not work when my PC is connected, whereas it works very well for example with the notebook and the PS4. I've tried all the configurations and have noticed that the switch doesn't work when my PC is connected, although it works fine with the notebook and PS4 for example. I'm not sure how to use this switch with a PC with a 3060 graphics card.
