Where are the CRT's?

Eye strain

One last thing....

The eye strain and the feeling of tiredness, and / or headache is due to the Verticle freq. The slower it is, the more it zaps you.

There was an interesting article in Scientific America about 5 years ago on this.

In short ( again ). Turn your Verticle Refresh freq. up as high as your monitor will allow to reduce the ( somewhat permanent ) damage from eyestrain, and other symptoms described here. I keep mine at 100Hz

Max

Wonderful maxvamp. That's the best definition of the CRT noise I've ever heard.

Just to add to it... Interlaced: It's a really terribile resolution where your monitor is basicly like a TV. It refreshes every even line, then every odd line. It really hurts your eyes.

FYI: I sware my CRT is silent... I'm running 1280*1024 and the Horizontal refresh rate is 91.1 KHz V is 85 Hz.

Now... If I use the same res, but down the V to 60 Hz, the H drops to 63.9 KHz

edit: oh yes... it's still silent at the 63.9 KHz

this is true

when i run my 21" trinitron , calibrated using super cal at 640x480 at 160refresh at1280*1024 at 120 refresh or 1600 at 100refresh it is so rock solid you would think it was an apple cinema lcd. even 2000+-1500+ at 85 refresh is good, its at under 85 refresh that the headaches come in to play.
however i have heard crts give off more radiation then lcd's thats why i wont one with no dead pixels for my next monitor
i was always wonder how does the 60refresh on Lcds come in to play
and if i play quake unreal at an average of 100 frames per second on say a crt set at 100 refresh and a crt set at 60 refresh will there be any noticable diff.
in shrt does the refresh rate play a role in fps games?, fps?

 

[daveg5]

oops

i meant lcd at 60 refresh compared to a crt at 100 refresh plying the same game at 100 fps

 

[MacMaelstrom]

Refresh rate really doesn't matter in LCDs. Also, the 60 isn't 60/second, it's 60 Hz... Which is going to be 60/second.... nevermind...

Sure they do, every been in a room with 21 CRT monitors all on at the same time? There is definitely noise, not as much as say with the older models but there is a definite high frequency level of noise. Most of the iMacs, we do not have iMacs in the lab, that I have encountered, CRT models, do make some noise as well, although not nearly as loud as older CRT monitors.

i sit down in front of my CRT iMac every day, and the noise is almost definatly the hard drive. when the hard drive spins down, it stops.
correct me if i'm wrong.

I'm defidently with you. I've never seen a post 90's monitor doing that. Probably even post-85

I can hear the monitor of my iMac DV. It's not the hard drive, I just put my computer to sleep and I could hear the monitor before the hard drive spun up.

It is very quiet though. I had to put my ear to the screen.

And the 60 Hz issue is because AC electricity alternates at 60 Hz, so if your electric lights are on, and they flicker in rhythm with your monitor, you go insane.

could it just be the heat rising thru that design, airpot card, or bad speaker, crossed wires or hot plastic
