Having had some time to swap and change settings now, i would say it's much much better. When mine was installed yesterday the sky engineer had left the Q box output set on 2160p, which is correct for UHD films and gives a stunning picture. However, if you then start watching say BBC1 HD, the picture lacks sharpness and punch. Changing the Q box output to 1080p when watching HD content changes that. The picture becomes as sharp and has as much punch as i would expect. I think the reason for this is that the upscaling that the Q box does is rubbish. With the box set to 1080p for HD content my LG Oled then does the upscaling and to be honest it blows the Q box out of the water.
