Check and see if your TV have a GAME mode, PC mode or something similar and enable that. On some TVs the settings are hidden.
Next check the HDMI input on your TV and make sure it is set to RGB and not YCbCr.
There's a review here. I asked them about the sensors in the comments section.

I use it with X-Plane and Prepar3D at the moment. Have not had time to try it with DCS.
Just a VESA pole bracket mount that I used with my office chair last time. WSP is working on a throttle adapter for the RGS though so you don't have to do it this way.
