Ես այլեւս չի պատասխանելու իմ էլեկտրոնային փոստով

The problem with the old CRT screens was that they only drew half the screen on each pass and then, only one line at a time.
That would only be true in interlace mode. As an IT person (and former radio & tv repair), I would always set them up in non interlace mode to prevent noticeable flickering. However in the later years, they did have 120 hz interlace available.
The flat screens are made, as a default, to accept 60 hz as a standard. The better ones are double-buffered (internal memory for screen buffer), which would make the actual screen independent. The back lighting bulbs should have a greater influence on flicker.
