Hi,
I bought an LCD 17" TFT monitor ACER AL732 - and I have a few questions :
What refresh rate is better for a resolution of 1280x1024 ? 60Hz, 70Hz,
75Hz, more ????
I was under the impression that TFT monitors don't have a 'refresh rate' as
such (As theres no electron gun firing electrons at phosphors, the pixels
stay lit ('twisted') for as long as they need to be. Whereas, with a CRT,
the picture has to be 're-drawn' at a certain rate (the refresh rate) as the
phoshors only stay lit for a short period after being hit by the electron
gun. Hence a low refresh rate causes flicker as the pixels start to fade
before they are re-excited) and those settings mean nothing if you are using
a TFT monitor.
What RGB color settings are better ? 50, 50, 50 ?
Whatever looks best to you. It's subjective, meaning, if you like it at a
certain setting and all your colours are clear and seperate without being
saturated then you have it right. Play and see. Both in games (if you are a
gamer) and when using it to do word processing etc. Maybe you have a couple
of pre-sets or user defined settings you can switch between. Say one for
games and movies and one for 'computer-type' use? The CRT monitor I'm using
(Philips) has pre-sets for games, movies, desktop use etc. as well as colour
temperatures. (Measured in degrees Kelvin) At the push of a couple of
buttons I can switch between optimal for games to optimal for desktop use.
They can differ a bit.
thanks in advance

ACER 17" AL732
Response time : 16ms
Brightness: 260 cd/m2
Contrast ratio : 450:1
Interfaces : DVI, s-video, analog
That's a good response time but the contrast ratio isn't too flash (on
paper). What's it like to use? It should be good for FMV, games and DVDs but
may lack a little 'clarity' for want of a better word. The contrast ratio is
the difference in brightness between pure black and pure white, I've seen
specs (on paper) as high as 1,000:1 but usually with monitors with a slower
response time.
Hmmm, got me thinking now. Do all fast-response TFT screens have a lower
contrast ratio than monitors equiped with liquid crystals with a slower
twist-rate (response time) and is it a function of the mechanisms involved?
I may have to do some research, unless there is someone who can post a reply
who has already looked at some figures for a few monitors or read some
reviews quoting these figures?
Typical, answer a question with more questions.
