Hi @Hifi_Naim_CNNL,
I use for this situation, two of (Häfele Keku panel clips, without lip, black makrolon) screwed to the back of each acoustic panel. This method only works if the thickness of the TV panel correctly accommodates the gap expected by the panel clip. In my case the thickness is ~7mm. In fact any suitable panel clip would work if it has the appropriate clearance and tolerance and rated load.
The screen is fitted to an electric moving mount, available in the UK from a company called Future Automation. This aspect is independent of the acoustic covering. In fact to consider the acoustic panels to be placed on the screen I had to check the total loading of the screen plus three panels remained within the load rating of the electric mount. Luckily, it did as I had not planned this solution when I started the project.
