So I have an HDMI Splitter set up so we can watch the same movie from our living room TV and our older TV in the Garage. The Living room TV is 4k 120hz, and the garage TV is 1080p 60hz. I have tried multiple splitters and HDMI receivers to try and downscale the output. But if it is outputting at 4k120 I can only get the Living room TV to display, while the garage is just a black screen. But if I put it on low-resolution mode, it will display on both at 1080p and 60hz.

Is there any way that I can take in the 4k 120hz output and have it downscaled so that it doesn’t reduce the quality of my Living room TV? Or am I stuck at 1080p 60hz as long as both TVs are being used? I am currently open to any suggestions that could work as I am getting pretty desperate. I really don’t want to have to reduce the quality of our Living room TV just to get the one in the Garage to work. Any help is greatly appreciated!! Also, let me know if my wording is confusing. I am bad with language. Especially English even though it’s my native language. Thank you!
