This is how I hook-up my PC with the TV in the next room, in order to View Videos on the TV. All connections are wired, which I prefer, as I can easily hide the 7 meter long cables (it would be possible to use WiFi with a NAS device near the TV).
Sitting in the TV couch I prefer using the Hauppauge remote control - rather than the Logitech RF mouse and RF keyboard. I have recently found smartphone apps for my Nexus 7 tablet to help me with quick web site navigation and entering text in search boxes: Advanced Touchpad, Remote Trackpad and Instant Remote. I prefer the latter one as it also works with Linux.
RF Remotes have the advantage that they can transmit through a wall. With the new generation of Android based mini PC sticks - which plug into one of the TV:s HDMI ports - there has emerged a series of RF remotes transmitting to a USB receiver. I have bought three RF Remotes for evaluation. They work with Windows and Linux as well as Android. The gesture control of the cursor is a bit tricky on Windows and Linux though, but can be mastered with some practice? The alternative is touchpad control of the cursor - might be better!
I also for use this setup to View Movies/Video-on-Demand on the TV and for Surfing the Internet on the TV.
