Why is there a frame tear on my Philips 42PFL7406H TV?

Question

NVIDIA

There is:
TV Philips 42PFL7406H (400Hz according to the description)
Nvidia GTX 1060 (6GB) I
connect via hdmi (cord like 1.0-1.1 version no higher)
The card gives about 70 frames, there is a wild frame break. Seems to be specific.
I read about frame breaks, they say that this is when the monik cannot be displayed more times than the card gives, the question is this. How can a 400Hz TV set not display 70-80 frames per second? Does he have Hz not real, or is the cord old? I already sinned on the nest (in the TV set, they say the old 1.1 and in the video 2.0 I read that everything is perfectly compatible, the throughput is behind the eyes)
Perhaps the reason is the processor that is weak i3 530 (2 cores at 4 GHz boost)
But this should not be, the TV cannot really 40 Hz be?

Answer 1

The card cannot give "about 70 frames".
It's one thing - the frame rate in the game, another thing - the refresh rate of the picture "in the cable".
What is the screen refresh rate in the video adapter settings?
Try setting it to a multiple of 100Hz and turning off all the "improvements" on the TV.

Answer 2

400Hz is not a real screen refresh rate, but with the insertion of intermediate frames, backlight flicker, etc., real frames are most likely no more than 60. G-Sync
was invented to solve this problem , but you need a monitor with its support. In general, a TV instead of a monitor for games is not the best idea, there may be other problems, such as input lag
