LG UBK90 4K Blu-ray Player vs Panasonic DP-UB820 4K Blu-ray Player

The Panasonic DP-UB820 is the stronger player for a serious home theater. It adds HDR10+ and HLG alongside Dolby Vision, a 32-bit/192kHz DAC, 7.1 analog outputs, a dedicated audio HDMI port and high-resolution audio files, and owners rate it higher. The LG UBK90 is a simpler, slimmer deck with Dolby Vision and HDR10, two HDMI outputs and region-free disc playback, but only Netflix and YouTube apps. Both upscale to 4K and play 3D on the LG; the Panasonic's HCX processor is widely praised for upscaling DVDs and Blu-rays.

• Choose the LG UBK90 if you want a slim, region-free Dolby Vision player for discs and USB files and you already stream through a separate stick or TV app.
• Choose the Panasonic DP-UB820 if you want the widest HDR format support, high-resolution audio outputs and the best upscaling for a dedicated theater setup.
