Sony HDI X800 - UHD - 2D/3D - SACD - Wi-Fi - Dual HDMI - 2K/4K - Region Free Blu Ray Disc DVD Player - PAL/NTSC - USB - 100-240V 50/60Hz for World-Wide Use & 6 Feet Multi System 4K HDMI Cable

Tried A and B region and worked fine. However, when connecting usb, it does not run even those files which are supported by ubp-x700. In case you are looking to use solely the blu ray disks, then its fine. Else it will be a big disappointment. Far cheaper and better options are available for that purpose.

Excellent, arrived faster than the delivery date, up and running in no time, Excellent picture and sound, 3d is brilliant, US plug not a problem, plugged straight into transformer, thank you AAAAAAAAA 😊

I think the people who had trouble with this machine forgot to read the instructions, including the inserted sheet that covers the hardware upgrade to achieve region-free capability. The first thing I did after testing that I could playa simple Blu-Ray after setting up for my monitor and wi-fi was to upgrade the firmware. Then, one after another I inserted all the 4K discs I own, to be sure they played properly - They did - followed by a variety of Blu-Ray, Blu-Ray 3D, and DVD discs. All played fine - No problems. Then I tried some Region B Blu-Ray discs: I turned off the machine, pushed the blue button until it restarted, and waited for it to load. The Region B disc played properly, too. This is a great player!

Ticks all the boxes for playback and connectivity.

I saw Aladdin, with Will Smith and Naomi Scott. I have never seen anything like it, on screen or off it. Compared to the garish primary colours which dazzled audiences in the late forties and fifties, it is a new world, in terms of a wealth of hues which would be a challenge to an artist painter, as they often radiate a light of their own, which we cannot observe in real life. The sharpness of 4 K image nearly makes the 3 D concept un-necessary. Now the 3 D discs proved a failure in my case. I was unable to make the display inviting to adjust both the player and the TV compatible to the 3 D format disappear off the screen. Adjusting the Sony 800 to 3D was easy enough, but I could not find anything to adjust on the 49" Sony XBR. There is no mention of 3D operation in the Owner's manual, nor in the screen display in the Adjustment panels. I was unable to play any of the 3 D I had on hand. I tinkered so much with various adjustments that I had to perform the ritual of Factory reset to at least restore the 4 K setting to its original glory. Considering the 4 K success, maybe we do not need the 3 D format, which could be a hushed failure.
