HTS7140/12 2:1 aspect ratio problem

Hi

I have a Phillips Sound Bar HTS7140/12 with the last firmware version 56

All MKV videos with aspect ratio 21:9, are completly distorced vertically without the top and bottom black borders.

Please could you add in furture firmware the ability to correct this problem?

Thank you very much.

Anybody from Philips read these posts?
