What an image ... but what an interface!
Bought to replace a 'fake' 4K that only did upscaling, this Sony model is a real joy in terms of image quality. Complemented by a Pioneer home cinema amplifier supporting Dolby Atmos, watching films encoded in this format is a feast for the eyes and ears.
The player is also DLNA compliant and will play your HD and UHD sources (mkv container though, old avi's even HD won't play for me).
But, and this is the big BUT, the interface is really shabby. Well, shabby, it all depends: if you're nostalgic for the MO5 and Minitel, then it's all good! It's still functional, but frankly, for 4k equipment, you'd expect something else (bearing in mind that the firmware is up to date and that Sony hasn't released any new firmware since 31/05/22).
