8×1 HDMI Switch 8 in 1 Out 4K @ 60Hz HDCP with 19-inch Rack-Ears | RS-232 / LAN Control | IR Remote Control and Auto Switch | Auto Scan Time Interval - Black

I give this 5 stars for good functionality at a reasonable price, but there are several issues to be aware of. First, this functions well as advertised. It's an 8x1 HDMI switcher supporting HDCP 2.2 and 4K (3840 x 2160) @ 60Hz. Switching can be controlled by front panel buttons, IR remote, RS-232, or Ethernet/IP. I use these on TVs where I have many HDMI devices that I want to toggle between. I have used this with Google TV, BluRay, Ubiquiti ViewPort, Roku, and other types of devices. I primarily use the Ethernet/LAN/IP control capabilities. I have Lutron keypads set to select the TV input. Programming the Lutron Homeworks QS system to enable switching HDMI inputs is relatively simple. Here are the downsides to this device: - The RS-232 port is a 3-pin connector that must be wired to a 9-pin Female D-type RS-232 connector to use the port. It's not hard to do, but this does not connect to a standard RS-232 cable out of the box. You will need to make a custom cable if you want to use RS-232. The manufacturer should include a 3-pin to 9-pin Female D-Type RS-232 adapter. - The LAN/Ethernet port comes set to a static 192.128.1.10/24 IP address. It does not use DHCP. The IP address requires using a custom Windows utility to configure. The Windows system running the custom utility must either connect to the static 192.128.1.10 address or use the RS-232 port. The device does not have a Web browser interface. It listens for hex commands on the IP address port (default 5000) in the same format as on the RS-232 interface. There needs to be a way to configure the IP address without using a Windows PC. - There is no way to factory reset the device. If you set the IP address wrong and are unable to connect over IP, you must use the RS-232 port to reset the IP address. The device should have a factory reset button or button sequence. Aside from these negatives, which make setting up the device more complicated than necessary, these are great little HDMI switches. I'm about to install the 16-input version on my main living room display, where I frequently switch between multiple security camera views and different AV devices.

This switch loses communication with the output device (My TV) approximately every 15-20 minutes and the problem seems to be getting worse. Since I replaced another brand that worked properly and simply connected the same cables to this switch, I believe the switch, itself, is the problem. A less important issue for me is that I am unable to insert two AAA batteries into the remote control. I would have to break off part of the remote to get the batteries into their compartment. Since I don't use the remote control, I could live with this if the device worked reliably but suspect many people would consider this unacceptable. I sent a request to TESmart asking for suggestions about fixing the lost connection problem and have not had a reply. I'm very disappointed since I like having physical buttons for each input and the large display indicating which is active.

I’ve had great luck with this device. I was surprised by the relative dearth of options for connecting multiple HDMI devices, since we all own a bunch by now. The device has been stable, reliable, and delivers clear picture. Also, customer service has been great. I lost my remote and they have replaced it free if charge.

I likes that it an 8 in 1 out HDMI switch. My only issue is I have 3 TIVO units hooked up- Romeo, Bolt and Edge and Nvidia Shield. It switches fine except with the TIVO Edge when I switch from the Edge and switch back I get an HDMI error, If I unplug it and plug back in it works again until I switch then I get the error again. I didn't have this problem with my old Zettaguard switch. Support has been contacted and they do respond but no cure as yet.

which is rather a pain since the TV set has "fancy" remote features that are trying of my patience. This unit replaced all that with a single box, just pick up THAT remote and switch to the input you want. p.s. I am the kind of gizmo guy that does NOT mind having a 1/2 dozen or so remotes.

I have used 2 others in the last 4 years and have replaced them both. The quality of this one exceeds my expectations. Well worth the cost

UPDATE: After literally months of back and forth messaging and troubleshooting with TESMart the audio issue stems from needing LPCM audio format support on your TV. If your TV or sound system or monitor or whatever output device you're using this with does not support LPCM your sound is not going to work properly. They need to update their page with this requirement, they claim an updated model is in the works but who knows how long that will take. I've tried THREE of these and it has the SAME issue. Certain audio channels are simply not playing. Music and effects are usually fine but voice/dialogue either doesn't play or intermittently cuts out. This is regardless of device, tried with multiple HDMI cables and TVs/monitors/speakers. TESMart please have your engineers look into this...I want to like this unit but that is a huge deal breaker.

I got this switch to handle the many devices I have ranging from Firesticks to gaming consoles. This switch does a great job of allowing me to connect all of my devices to it, providing a crisp. high quality picture. My only gripes are the fact that the switch will randomly change source inputs at times, and the remote has a very weak signal coming from it, meaning that you have to mash buttons 4 or 5 times to get to the input to change. Overall, it is a good product.
