Review on 🔌 4K HDR Dolby Vision Atmos Down Scaler HDMI Splitter 1x2 - HDMI Scaler 4K 1080P Sync, 4K 60Hz 4:4:4 HDMI Splitter 1 in 2 Out HDCP2.2, EDID 4K5.1/4K7.1/Copy, for Xbox PS5 1080p120Hz Roku SP12H2 by Andre Hawkins

My problem: I have connected a 1080p projector to the video output of a Yamaha TSR-5810 AV receiver and a Revain Fire TV 4k (pendant) as input. Since the projector is 1080p, the counterpart only gives me video up to 1080p, Dolby Atmos is of course not available. No matter what settings I tried on the projector, AV receiver and hanger, no Dolby Atmos! The only thing I really need is to spoof the trailer with a 4k TV signal. I searched the web, someone suggested using HDFury, but the price turned me down. I searched again last week, I found something called EDID and then I found this little gem! Solution: The only thing I changed with this $30 box was I added this box between the AVR and the projector. Here are the details: switch EDID to 4k, connect my AV's video out to video in and my projector to video out 1, voila! A star (maybe half a star) is deducted due to the lack of a power supply. I just plug the power cord into the AV's USB port, everything works great. UPDATE: I'm using the power adapter for my old Fire TV Stick, it works. I'm fine now, UHD makes my projector look better, but Dolby Atmos only comes with UHD HDR source and the picture looks a bit washed out! I think I'll get a 4k projector at some point, but that's at least another $1,000 and up. As long as I'm happy (with pain)! I have to deal with HDR. But that has nothing to do with this gem. Hope this helps someone else like me.
