Review on 🔌 Ailun HDMI Switch & Splitter: 2 in 1 Out, No External Power Required for Xbox, PS4, Roku, HDTVs - Ideal for High-Definition Television Viewing (Not for Dual Monitors) by Michael Moonin

Doesn't work as efficiently/cleanly as I would like. The button to switch from HDMI 1 to HDMI 2 or back again is fine except it's not clean when it comes to the TV side. I have HDMI IN 1 with ROKU and HDMI IN 2 with BLURAY so OUT HDMI feeds my TV as I only have one HDMI port for the TV so I need a switch to accommodate both components. I can look at 1 via ROKU and then switch to 2 on BLURAY with the push of a button. No problem. But when I try to return to ROKU on 1 I get a blank screen. I have to turn the TV off and on again. So there's something missing in the process and I don't think I can blame my TV for that. Also, and unexpectedly, when I enable 1 for ROKU for the first time, I usually get a brief flash of an HDCP warning, which is not applicable since no write attempt is being made. I even swapped out the HDMI cables to fix this issue and it's iffy.
