J-Tech DigitalUSB C to HDMI Adapter 4K 30Hz 1080P 60Hz, Dual Monitor Adapter USB-A or USB-C in, USB Powered, Mirror Extend Rotation Clamshell Modes [JTD-USB-2HDMI]

Second edit: I contacted the company about the problem and they were going to immediately send me a new one and I was supposed to get it by a certain date. Days and it was never sent out. Then they were going to overnight it. I didn’t get it overnight. I got it, three days later than what they promised.. I installed the new one today. It worked on one TV with a picture, but I didn’t even bother with a second TV to see if I got a picture because the sound didn’t work, I called them again today.. The one that I received today wasn’t the same as the one that I was trying to replace it was from a sister company. They are going to try to replace it, but I’m not sure which one if I’m getting from Service or the sister company which had a plug that was too big for my power strip, and I really had to waste plug space because of it. They can’t overnight it The second replacement I’m not really very happy with his company. They’re going to send it by ground.Edit. I purchased this May 17, 2024 and today is August 4, 2024 and it died today. I’m very unhappy. I hope it has a warranty longer than 2 1/2 months, And I hope it can be replaced quickly.I purchased another highly rated unit. It didn’t work at all and their customer service was nonexistent. This unit worked perfectly. It was easy to set up. I have a TV and cable box in my living room, and my bedroom shares the same wall, it just seemed crazy to pay for another Cable box. I bought a long HDMI cable and put the splitter in.. I bought a splitter along time ago, that eventually died, so I could watch TV in my bedroom. I can change the channel with the remote app in my phone. If I want to watch TV in the bedroom while I’m working around the house as well as in the living room, I can do that. I also can watch TV in bed and have the TV in the living room turned off. It’s great and works perfectly!

I’m using this to downscale my AppleTV output for an older Marantz pre-pro. HDR10 works great and looks great. But my JVC RS1200 supports HDR10+, and I’m not seeing that option any more on my AppleTV. Not a huge deal, just something to be aware of.Update: every time I turn off my projector and AVR, my AppleTV loses its memory of the video settings, and I have to re-enable HDR. So for now, I guess I’ll just stick with SDR until I can buy something that doesn’t confuse the AppleTV. I’m still happy with what this does, for the price.

You can duplicate displays, but you can't extend themI recently tested the J-Tech Digital HDMI Splitter, which features a 1 input and 2 output configuration. Note that the splitter does not come with an HDMI cord, so I used my own. I didn't realize that this splitter wasn't able to split to three monitors. During my testing, the device successfully extended signal to my second monitor without any issues. However, when I tried to connect a third monitor, the splitter only duplicated the display from the second, rather than extending the desktop. This means that I could only view the same content on both outputs, which isn't what I needed for my multi-monitor setup. So, if you want to expand your workspace across multiple monitors where each screen displays different content (for instance, setting up displays 1, 2, and 3), this product may not be the best fit for you. That said, it might work well for someone with needs more aligned with duplicating displays. Overall, while the splitter performed reliably, it simply didn’t meet my expectations for extending my desktop across multiple monitors.

Works great! Some reviewers mentioned lose of video quality, but I haven't noticed that. I used it to split my video and sound from my FireStick as my TV is very old and it didn't have HDMI Arc or Optical sound ports.

Great piece.I have two of them. They work quite well Compatibility and durability is off the charts

This review is for the JTech 4x2 matrix, NOT the cable splitter. As noted by many, the item is well made, very compact, and has a remote, and AC adapter. My specific requirement was to split the optical audio signal from my Sony HDTV to a ZVox 440 sound base and Yamaha RN-303 receiver.Read the instructions. You can input 4 audio sources (Input 1, 2,3,4), and send the signals to 2 Outputs (Output A/Output B). In my case, Input 1 was the Sony optical audio signal, and Output A was the ZVox, and Output B was the Yamaha. Hooking up was a snap. Some have not been pleased with the brightness of the display, but I am fine with it. The unit has an on/off button, and buttons to manually change the set up, or you can use the remote. The remote is very small and thin, but the buttons are big enough. Suggest you be careful and place the remote in a safe place, as it could get misplaced because it is so small. This matrix is as advertised, as it does the job, and the audio signals are strong and I have not experienced any hint of sound loss.I highly recommend this unit. You may be shocked at its compact size, but the JTech folks have brought us an exceptional solution for those seeking to port optical audio signals, without using Y cable/splitters. Also, the JTech technicians and customer service folks are a simple phone call away to aid you with any questions or problems you may encounter.Buy it with confidence.
