On or about Sun, 11 Feb 2007 23:04:06 GMT did "therowdy via HWKB.com"
<u31658@uwe> dribble thusly:
| Quote: | I have a new Samsung 940B analog/digital monitors. It has a refresh rate of
8ms but the recommended screen refresh rate is 60hz. I am told that 8ms
monitors should be set to 75hz to obtain the 8ms refresh rate.

8ms is the (advertised) response time, not refresh rate. That means
it takes 8ms for a pixel to change from one color to another. Or
less. It depends on the magnitude of the color change. If it was
advertised as grey-to-grey, then some changes will take more than 8ms.
Strictly speaking, you'd need a 125Hz refresh rate to match an 8ms
response time (1000/8 = 125). But you wouldn't notice the difference,
since LCD's don't flicker like CRT's do, and 60 updates a second is
plenty.
| Quote: | Is there a reason why Samsung recommends 60hz rather then the fast capable
speed of 75hz? Loading the Samsung driver actually hides all other then 60hz.
I wrote to Samsung and all they said
8ms is the response time of the LCD panel itself. The total monitor response
time also includes the signal processing time in the circuit.
Increasing the fresh rate to 75Hz does reduce the signal processing time but
it does not show as obvious as the panel itself.
We still recommend 60Hz refresh rate for all LCD Monitors
|
Not really sure what they are trying to say, but it doesn't matter.
You will not see anything different with a higher refresh, so don't
worry about it.
