Uchida Yoko - Wall-mounted monitor? I think that's the right way to put it. These are brackets for hanging monitors from the back. Please feel free to ask any questions. I have several of these that I no longer need because I switched to 42.5-inch 4K monitors. If you are concerned about the condition, please purchase new ones. #office #UchidaYoko #wallmountedmonitor #office #officemachinery #computer #attachment #bracket #monitorbracket
