The product is great and works exactly as advertised. For me the best part was the customer service I received from StarTech when I had an issue. About 3-months in my spliter stopped working. I called StarTech's customer service and after answering a few questions, a brand new unit was on it way to me (not refurbished or repaires, but a brand new one).. I also wasn't even required to send the old, not working unit back. Got the new one in a couple days and was back in business. Now this is what great service is all about. This company backs it products and makes it right if there's an issue on their end.

This is a great HDMI Splitter. Love it. Solve my issue 4k HDMI splitter. Thats what I wanted. Some other items I purchased stated 4k HDMI splitter but it down scale from 4k to 1080p.
Don't waste your money, these things are useless.

Funziona bene e fa egregiamente il suo lavoro di portare il segnale della sorgente video a due schermi differenti anche in risoluzione 4K. Essendo uno sdoppiatore non permette (se collegato ad esempio a una scheda video) di differenziare i due schermi, avrete sempre la stessa immagine in entrambi i monitor (o tv) quindi se cercate quel tipo di prodotto questo non fa al caso vostro.Dalla mia esperienza se lo collegate contemporaneamente a due televisori o monitor con definizione differente verrà ritrasmessa solo la definizione "inferiore", ad esempio se utilizzate contemporaneamente un dispositivo 4K e uno in Full Hd in entrambi gli schermi vedrete il segnale in ful HD.

Not perfect but very useful. It requires a power outlet and the power cable is really short, but all is included. You will need your own spare HDMI cable of course. Set it up and forget about it. It will mirror the game to both screen. I primarily got this so I could use my older 1080p 32" TV for Amateur Sim Racing (left OUT) and game on the 4K 50" TV (right OUT) without having to plug/unplug the HDMI all the time and risk damaging the connectors or ports. It dowscales automatically the 4K signal to the 1080p second screen. Only 60Hz, but this is both my TVs refresh rate anyways. A 120HZ model might be required if (/when) I upgrade my larger screen. If you are on Console (I'm on PS4 Pro, soon PS5 Pro), you might need to turn off the feature that lets your console turn on your TV automatically as if you turn the TV OFF it might actually put the console in sleep mode. Small inconvenience, you will have to turn the one TV you will be using manually. The horror /s. 4 stars because of the short power cable, forcing me to let it hang behind the console, and only 60HZ.
