Not always true. It depends more on the ballast type than the lighting
type itself.

The flicker is worse if you also have tube lighting - in continental
Europe with 50Hz power a 60 or 75Hz screen refresh results in
interference of 5/6 or 2/3 seconds, but in the US with 60Hz power a
60Hz screen can build up a very slow flicker (if only a fraction out
of sync) or in a constant 30Hz flicker (when the screen is in its
"dark"-phase while the tube light is in the bright phase).

I am pretty sensitive to screen flicker too. I keep my monitor set to 75Hz
refresh and that seems to work pretty good. (this is an older Dell Ultra
Scan that is slowly fading) My previous (now dead) monitor supported even
higher refresh rates and I kept it set to 85Hz (both monitors at 1024 X 768
Res.) and I never did have a problem with flicker. A lot of companies seem
to set their user's monitors to a default of 60Hz refresh and that will
usually produce a noticable flicker for a lot of people. Some don't notice
it for a while or just wonder why they get headaches so much. Up the
refresh and things improve a whole lot. (that is as long as the monitor
supports a refresh rate of 75Hz or more.)

My problem is that I'm extremely sensitive to CRT screen flicker. At
work most of the PCs "on the floor" drove me nuts after 5 minutes use.
My boss must have had a better one that wasn't as bad, but it still got
to me after a while.

For some reason the ones on my Macs at home were didn't bother me until
around three years ago. I don't know if I got more sensitive to it or if
my 19" NEC multisync got worse, but it started to bother me. I got a 22"
Apple flat screen and have been a happy camper ever since.

The more expensive TFT monitors have DVI input too. And are much better. But, having used both CRT and LCD monitors, I still prefer CRT for image proccessing. james > > >CRT's are analog devices.

CRTs are the choice of pros. LCDs are like the digital vs film debate. LCDs lack the contrast, resolution, color saturation of CRTs.

Sorry if this topic has been covered before...if so, steer me in the right direction. I have PS on a laptop and want to use a desktop monitor. Which type is better for editing photographs, LCD or CRT? I have a TFT screen on my laptop and the color saturation changes with the position of the screen. Thanks for your help, Oscar
