Get an HDMI switch to let you add more devices.
Keep in mind that HDMI has a typical limit of about 15 feet. Sure they sell longer cables, but the signals can cross-talk and cause issues with longer runs.
You would be better off buying a Roku/Chromecast and streaming videos straight from the PC. This would probably cost less than a long HDMI cable and work better.
