Buying an LCD Monitor - Qs

Archived from groups: alt.comp.hardware.homebuilt (More info?)

I want a video card that only has DVI, but I am interested in some LCD
monitors that are analog. Is a converter OK, or would it noticeably
degrade the picture and speed?

I found LCDs with response times ranging from 8ms to 25ms. Obviously 8ms
is the best, but what is the maximum that is decent enough for gaming on
a 17” LCD? 19” LCD?

the response time the manufacturer's use is the time it takes the lcd to
change from black to white .. colour takes longer to change than white
... a 25ms LCD monitor from a decent brand can actualy outperform a cheap
16ms LCD monitor obviously this is not always the case typicaly the
quicker the response time the better .. also check the monitor out first
in a shop if you can. I went from a CRT to LCD about 12 months ago "I"
find LCD monitors harsh on the eyes due to the lighting method used also
the light is typicaly only rated to last 3yrs.

A quick google search shows 30000 hours mtbf to be typical.

This equates to 3.4 years if used 24 hours per day 365 days per year.

A more typical 4 hours/day for a home machine gives you 20 years.

Maybe people should turn their monitor off when not in use! (It helps the
environment too)

Good question though Conner, any scientific mush, to confirm this?
Don't get me wrong, I don't disbelieve you, but some info will be good.

Methinks there's a bit more to it than that.

Just off hand I'd speculate there's a difference in response time between a
full scale, on/off, transition vs a partial, I.E. gray to gray, transition
but that wouldn't be because it's a 'color', per see.

Spot on.

Half life of the bulb can be ~3-4yrs...
o Most (desktop) LCDs have an output that at maximum is too bright
o So the usable life of the cold fluorescent tube is somewhat longer

A CRT has a half life of around 6-9yrs as I recall.
LCD bulb half life is more an issue for laptops - some cheaper laptops
have quite poor output tubes, halving would make them near unusable.

Colour temperature can be a factor in preference of an LCD...
o Some people like the clinical colder blue
o Others the warmer softer red tinge setting etc

Realise that LCDs are still a little poor at colour rendering:
o Viewing angle is an important consideration for any application
o Colour rendering is generally inferior to a CRT for photo retouching

LCDs do vary markedly...
o Philips used to be the best for image quality
o Response time alone (Tr+Tf) is only one data-point

The bigger LCDs are getting quite heavy, so that benefit is somewhat
less than it used to be compared to CRTs (that said 21" CRTs weigh :-)
