Works great on its own Can only work on its own, not intended for connecting external devices via HDMI. Do not buy under any circumstances if you have a home theater, Blu-ray player, or set-top box (Android, satellite, cable, no matter which one)! Unfortunately, I don't have a gaming console to test movie playback on it.  AXE KÖNIG: use Samsung QE-55Q77A less than month |
Solutions from Samsung with newfangled QLED matrices are in great demand in the medium TV segment. One of these proposals is the QE-55Q77A model with proprietary Dual LED backlight technology based on quantum dots.
QLED panel
QLED technology achieves a significant increase in brightness and color saturation at the same time as improving color reproduction. The TV panel displays a picture in high resolution 3840x2160 pixels, boasts a high refresh rate of 120 Hz and support for high-quality HDR video output in HDR10, HDR10+, HLG formats. Samsung QE55Q77A pleases the audience with a clear and smooth image, regardless of the type of broadcast content.
Tizen proprietary system
Multimedia functions on the TV are available thanks to the proprietary Tizen 5.5 system. It provides user interaction with popular streaming services, online cinemas, video hosting clients and social networks, and allows you to play files from USB drives. The operating system supports voice control through Google Assistant, Amazon Alexa and Bixby.
surround sound
The visual audio on the TV screen is performed by 2 x 10 W stereo speakers, supported by Q-Symphony surround sound technology. Also on board the model has an omnivorous digital tuner for watching traditional TV broadcasts. The slender body of the TV panel is supported by one leg on the platform. Instead, you can use the services of a VESA wall bracket in the dimension of 200x200 mm.
1. When supplying standard video 24 frames/sec to any HDMI from any source, there appears a monstrous input lag and very noticeable judder (shaking and frame skipping) - a regular film, regardless of resolution, turns into a random slideshow (including in HDR). It doesn't matter what the signal source is. The only solution is forcibly switching the HDMI mode to "PC", but in this mode, image settings are entirely unavailable, you cannot select Filmmaker Mode or Cinema mode, and watching a film in such conditions is eye-straining. There's no such issue with video at 30 frames/sec or 60 frames/sec, but the vast majority of film content is at 23.976 frames/sec, making it unwatchable from external HDMI inputs. All sharpness settings have been tried 800 times with different variations - all in vain. So a Bluray film with a home theater can only be watched either in slow slideshow mode or in "eye-watering" mode. I haven't noticed such problems with playback through the TV's built-in means, but...
2. The HDMI-eARC setting is broken. More precisely, enabling it completely disables audio passthrough to the home theater via the return channel. It doesn't matter what audio codec is in the video content, the TV tries to send DTHD to the home theater, which collapses after 2-3 seconds and switches to lousy PCM. If you don't touch eARC, then in regular ARC it correctly passes DD and DD+. In addition to Samsung's refusal from DTS, this is a monstrous blow to home cinema enthusiasts.
