Video Description

I’ve been using the OREI BK-4927 HDMI 2.1 switch and audio extractor for about a week now, and wanted to share my experience setting it up and using it day to day in my home theater. If you’ve got a newer TV with HDMI 2.1 but an older receiver or soundbar, this might be exactly what you need. It lets you hook up multiple 4K120 or 8K60 devices, automatically switch between them, and still send proper audio (including eARC) to your receiver or soundbar. Everything I tested worked as expected: no sync issues, no handshake problems, and it handled Dolby Vision, HDR10, and VRR just fine. OREI sponsored this video and sent the unit over, but everything here is based on my own real-world use. If you’ve been running into HDMI 2.1 or eARC headaches, hopefully this helps you figure out if the BK-4927 is a good fit for your setup. 🔗 Check out the OREI BK-4927 here:https://www.orei.com/products/8k-60hz-4-port-hdmi-switch-hdmi-audio-3-5mm-optical-bk-4927 👍 Thanks again to OREI for sponsoring this one, and thank you for watching! If you found this helpful, consider giving it a thumbs up or sharing it with someone setting up a new HDMI 2.1 system. #homeTheater #HDMI #OREI #HDMI21 #eARC #4K120 #8K60 #HomeTheaterSetup #AudioExtractor #GamingSetup #PS5 #XboxSeriesX #AVGear Basic calibration tools that might change your life: VLIKE SPL Meter: https://amzn.to/34iKve3 UMIK-1 Measurement Mic: https://amzn.to/3qs8noy miniDSP 2X4 HD: https://amzn.to/2XOiUym Spears & Munsil HD Benchmark (Blu-ray): https://amzn.to/3oQ5Q8h Digital Video Essentials: HD Basics (Blu-ray): https://amzn.to/3fouWIo Disney Wow: World of Wonder (Blu-ray): https://amzn.to/34llKhi My Home Theater Valenica Tuscany Ultimate Luxury Edition theater seats: https://us.valenciatheaterseating.com?sca_ref=2381969.gq6ABvF7ex LG C1 OLED 77-inch 4K TV: https://amzn.to/3Ts1QJi Denon X2300W Receiver: https://amzn.to/2CuemWI Pioneer SP-FS52 Floorstanding Speakers: https://amzn.to/3jpREzs Pioneer SP-C22 Center Speaker: https://amzn.to/32zytgQ Pioneer SP-BS22 Speaker Pair (L/R surround): https://amzn.to/3fM5ryl Polk VT60 In-Ceiling Speakers (linked to 70-RT): https://amzn.to/3MHNZwg Dual SVS PB-2000 Pro Subwoofers: https://www.anrdoezrs.net/click-100199167-14296642 Dual SVS PB-1000 Pro Subwoofers: PS5: (basically won the lottery) XBOX Series X: (another lottery win) Nintendo Switch: https://amzn.to/30olzj2 LG UP970 UHD Player: https://amzn.to/2CuvDix Apple 4K TV NVIDIA Shield Pro (2019): https://amzn.to/3mzML9d miniDSP 2X4 HD: https://amzn.to/2XOiUym UMIK-1 Measurement Mic: https://amzn.to/3qs8noy My Gaming/Editing PC MSI B450 Tomahawk: https://amzn.to/3hjYrJu Ryzen 9 3900XT: https://amzn.to/38A01FV Corsair Vengeance RAM (4x8GB): https://amzn.to/32BC2TJ NVIDIA RTX 2070 Super: https://amzn.to/2ClnbCj Crucial P1 500GB NVMe: https://amzn.to/30yxyui Sandisk Ultra 1TB SSD (x2): https://amzn.to/3hjm4lo Seagate Barrucuda 2TB Drive: https://amzn.to/2DVokAI Seasonic GX-750 PSU: https://amzn.to/30t0sfB Phanteks P400A Case: https://amzn.to/2Wy6MRN Corsair H115i Elite Capellix AIO: https://amzn.to/3pqUZAN RGB Strip Lights: https://amzn.to/39egZrz Corsair K55 Keyboard: https://amzn.to/3eKxaya Corsair Harpoon Mouse: https://amzn.to/30rtbkV HyperX Cloud Alpha S Gaming Headphones: https://amzn.to/3buDOut Focusrite Scarlett Solo (2nd Gen): https://amzn.to/3jpGL0A Audio Technica M40X Headphones: https://amzn.to/3fOz6qz PreSonus Eris E3.5 Studio Monitors: https://amzn.to/30sVOyb Audio Technica AT2020 Condensor Microphone: https://amzn.to/30xUn1v BenQ EX2780Q Monitor: https://amzn.to/2BfBW90 BenQ MOBIUZ EX2710 Monitor: https://amzn.to/32YcTCs AOC 27G2 Monitor: https://amzn.to/2CuL7TI *Disclaimer: Brad (Home Theater Gamer) is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to www.amazon.com.
