Such high refresh rates may not be supported by pixel response times, resulting in distorted images.
Another problem was that the mechanical filter made them flicker unless very high refresh rates were used.
A high refresh rate (above 75 Hz) also helps to negate these particular effects.
I tried to correct the problem by testing a number of different refresh rates, but couldn't get it to go away.
Higher refresh rates, while they reduce flicker, may cause other problems.
The signs supplied to businesses typically have lower refresh rates than full video displays.
This technique is only useful though, if the source material is available in higher refresh rates.
For higher refresh rates, packets having fewer than 512 channels can be sent.
Instead, we used vertical refresh rates consistently in excess of 100Hz.
A television with a low refresh rate will have problems displaying fast-moving images.
