If set up correctly an IR Extender will work fine. Typically the transmitter connects to your source and the receiver is placed in line
of sight right by the TV. I use HDMI Extender solutions for runs over 200ft. There are very few Companies that have solutions for extending HDMI over 200ft. I recently purchased a couple of long run HDMI Extender units from KVMSwitchTech and they work well.
