TCL has done its homework. She designed a new extremely expressive model with bevelled aluminum.
What is chamfering: https://pl.wikipedia.org/wiki/Fazowanie

And here is a beautiful view of the bevelled aluminum frame.
Aluminum - because the company does not go for a plastic easy but for VIP expectations even at this price class.
It gives the effect of a cut diamond. The TV will decorate any apartment.
There will also be Local Dimming, Creative Pro, extended color space, 10-bit display, Android 6.0.1 operating system, HDMI 2.0 and JBL speakers.

The speaker cover is woven as if with silver thread which emphasizes the uniqueness of the appearance. But the most important thing is that the full stereo sound will be forward to the listener and ensure signal clarity.
Very precise performance of chamfered aluminum.

Contrast is as Calman 5 says - so please direct comments to the producer that she did too well. I think that this time he will not be offended ...
Commands always apply to the price class.
The colleague apparently fell out of the beat and did not notice that all manufacturers (except for Philips) in the new models have only 50 Hz.
And my colleague hardly saw the model at work, so it's hard for him to give his own assessment.

The same Claman company tests and the results are the same as in the world (applies to other TVs). They will give you the best rating - they have zero complaints.
