Review on Orei 4K HDMI Splitter 1x4 - 4 Port 4K Screens Duplicate 60 Hz @ 8-Bit - HDMI 2.0, HDCP 2.0, 18 Gbps, EDID Support - UHDS-104 by Roman Niko

This is definitely an affordable way to split one unit into 4 TVs. As TVs keep getting cheaper, this product makes it easy and affordable to create a TV wall for your game room. Using a multiport to connect multiple devices. The quality is excellent on PS4, PS3, Xbox 360, Fire TV, Nintendo Switch and Wii, DVD players and laptops. The only one with quality issues is the Xbox One, the image shrinks and gets a bit blurry. Maybe try a booster, maybe it will help.
