Do not bother with this particular product at all. It will not work properly because it operates passively, without its own power supply, resulting in the inability to send the signal to two screens simultaneously. Maybe with very short cables, I don't know. Anyway, with the same amount of money (or even less), you can get a splitter with a power supply that will definitely work, with cables up to 15 meters long. I made a mistake and had to buy a splitter with a power supply.

Unfortunately, I also just tried to connect 2 screens from my laptop, no signal on both. One is not a problem but for two... there is an issue. I think it needs a splitter with a power supply

This specific splitter does NOT duplicate the image as I thought, but it only works with one of the two ports at a time.

I would say that this product is one of the things that should be considered necessary, more specifically it is necessary for those who have 2 screens or want to buy a second one and only have an HDMI slot or simply want to use HDMI for security! Personally, I believe it is the best option because you never know if the rest will work and most monitors or TVs only have HDMI on them, so this product helps a lot!
