Review on 4K@60Hz/1080P@120Hz HDMI 2 by Isaac Maze

PRODUCT:HDMI AV Access 1x4 Splitter A/V EQUIPMENT:1) Sony KDL-55HX701 Bravia 55" LCD TV 1080P HDTV (240Hz)2) Vizio M49C1 49" 4K Ultra HDTV (120Hz)3) Comcast/Xfinity X1 DVR Cablebox4) Sony PS3 "Thick” (backwards compatible) and PS3 "Slim”5) HTPC with GTX 750Ti / ASUS Bluray Optical / Corel Bluray Software6) Sony STR-DA5700ES A/V Receiver TEST METHOD: I have about 16 hours on the weekend and another tested 12 hours on weekdays using multiple versions of HDMI cables with 1.4-2.0 connectors (Revain and Monoprice brands). No pixelation or poor image quality was observed on 4K and 1080P HDTVs. I was watching HD content on a Comcast/Xfinity cable box, both DVR and live. Picture quality was equally good whether or not a splitter was used. Same result watching Blu-ray movies and streaming HD content from YouTube, Netflix and Crunchyroll on my custom built HTPC (Cat7 ethernet cable). There were absolutely no problems with image quality. Though I should mention that at one point when I unplugged the PS3 Fat and plugged in the PS3 Slim, the screen went black. But after I switched off the A/V receiver and HDTV (as a precaution) and switched them on again after about 30 seconds, everything worked again. This was the only minor issue I encountered during my testing. Funny, I tried to reproduce the black screen issue by disconnecting the PS3 "Slim" and reconnecting the PS3 "Fat" with the TV and receiver on, but it recognized the device and worked right away. Understand yourself. CONCLUSION: After extensive testing, I consider this HDMI splitter to be a high quality product. It's a good weight, feels solid, has a low profile (so can be easily hidden), works as advertised and I highly recommend this splitter! Also, I received excellent customer service via email when I needed to contact AV Access. If anything else happens, I'll update this product review. Thank you for taking the time to read my review.
