the only option that work for the image is line 2x, no 3x, no 4x, no 5x.
This is typical. There are a lot of TVs that simply don’t support or like the resolutions or refresh rates produced by 3x, 4x, and 5x. You should check the TV compatibility report thread for known-good displays, and you may wish to post your own results.
For the remote, it works but not well : the ir signal is extremely low and i have to press several time the buttons to make it work.
Have you tried new batteries?
