Best for the eyes, CRT or LCD?

i hear people swear up and down favoring one or the other. depends on the individual i guess. try a FAIR experiment, under normal room lighting and with common source material...LCDs being better in bright light, CRTs better in darker. settings..

CRT - 75 hz. vsync on.
LCD - digital connection (dvi/hdmi). set source material to native resolution. turn down the brightness (most are made too bright in order to hide poor contrast ratios) - then view the "useable contrast ratio" - the one you will be seeing when brightness is accepable. vsync on. see if ghosting bothers you while scrolling text (try them side by side. i say that because its a fact people see things not otherwise noticed that way - like ghosting on lcds).

proper calibration, latest drivers... what else ok hope it helps.

LCD is just generally better because it doesn't have radiation like CRT's do, also they don't flicker because the entire screen isn't constantly updated like they are on CRT's..

LCD is WAY better to sit in front of then CRT's.. without question

Not entirelly accurate. It is true that LCDs have near zero elecrtromagnetic emission but that does not make them less strenuous to the eye as per se. A good CRT working at 85 or 100 Hz is completely flicker free. Moreover its vastly superior clarity requires of the eye less effort in order to focus on fine details, say, text. That is exasperated by the tendency of manufacturers to turn up the brightness in TFTs in order to cover up for their poorer contrast. CRTs on the other hand with their more vivid coulours can be more tiresome in games but then again their image quality and colour depth is head and shoulders above that of TFTs.

I would have to say that my eyes experiences less strain when I'm looking at an LCD monitor for a prolonged period of time as opposed to CRTs.

Yeah I have an idea as a matter of fact; TFTs are usually too bright at their default settings.

HI,
Ever since I had lazor surgery on my eyes I am now extra sensitive to monitors.
with my experience here are all the things that will help. I need to look at screens for over 8 hours a day, 2 screens at work and im a gamer at home.

1) drop the crt if your using one. i cant even look at one now for over 1/2 hour now
2) keep your screen al least at arms length away.

remember even with lcd, selection of the bigger screen the harder on the eyes.
pick the largest size of a comfortable range with the smallest native resolition.
some lde pixels are way too small , a good size is 22" wide 1600x1050.

monitor brightness -- thats where it's at.. You need something that can tone down its bright whites without compromising overall color. Contrast just dont cut it.
turn off any color enhancement features as they hurt too. All these features are signs of an extra bright monitor. The worse monitor i ever owned i called it the eyebleeder.. HP 24" widescreen. cd400 brightness is a big no no for eye eyestrain. cd300 is ok. 250 is prefered if you can find them.
Bleeding of light is another indicator of a screen that is too bright. If you place up a black screen and see loads of light around the edges then it could cause problems. THe best i have seen for no bleeding is Dell. I can stare at 2 of them all day ar work with no issues. there is 0 light bleeding on my work screens. I just turn the brightness down some and it's cuts out the extra bright white intensity.

Another note.. If you find any monitor that you can turn the brightness down to 0 and it's still bright! well that should speak for itself! skip that complete model line for your choice.

Now for monitor settings. ATI has some nice features for this . you can set desktop and 3d enviroment seperatly.
In the color settings, you can select a feature call saturation.. its kinda like the same color enhancment feature monitor provides. if your color seems a bit too cartoon like. Open up a personal outdoor photo and adjust so it looks "real" not extra nice and bright.
Gamma can also be toned up afterwards if you find some of the blacks are now too dark. this is found under color settings also. contrast adjust normally.

The last thing i can think of is font and remember ever bit counts. You need to use true type font on an lcd , this is great for reducing eyestrain. Do whatever you can to keep your font clear. ALWAYS run your LCD in native resolution, any less will cause pixel blending over the additional pixels ( blurred text ). this is very important.

For me Dell and Samsung are the best. Dell is by far most superior in ever way for reducing strain. ( i never tried the new 23 + screens but plann to ) possible they may be a bit bright also. Dell is the only monitor that clearly had no light bleeding out around the edges up to there 22" That will be my next test is i ever decide to go 23" + i have to weigh in the fact tho that the 23" has extra small pixels tho well. wither way. I wrote this hoping to help everyone with this. There was and still times i strain my eyes so bad i cant even looks at tail lights at the car in front of me when following another car to work.. yeah.. its that bad. Today I manage my eyes to be able to play games for a few extra hours a day.. anyway.. Good luck to you all.
