Review: Perfect - This device is excellent. I wanted to use an unused Samsung soundbar with my new triple monitor setup. I had 3 gaming consoles and wanted them all connected to only the 4K HD monitor while I use the other two monitors for my work using the laptop. This device made me connect my PS5, Steam Deck, and Nintendo Switch 2 and receive full 4K 120Hz with HDR, VRR and ALLM on my monitor while receiving perfect sound from my soundbar through an optical cable. I couldn’t get the PS5 to show output info as 4K 120Hz until I ran Monster Hunter Wilds. You must be running a game that supports 120Hz if you want to make sure such devices work! Thank you for creating such a niche product that delivers exactly what it promises. I read that some of these devices fail to deliver the specs they advertise.
