CRT is primal technology by today's standards, plus they're super dangerous if you break them.

Uh what? The vacuum inside them makes them quite safe, since any breaking glass gets sucked inwards rather than exploding out.

it's not the glass, it's all the shit inside of it. I remember when I did my A+ cert (yes I know this isn't a real qualification) some years ago they told us it was dangerous to break them

Did they tell you cellphones cause cancer too?

tl:dr; Breaking a CRT won't do anything. IF it suffers a failure that causes HV build-up, and IF you're silly enough to open it up, and IF you pry off the big rubber pad covered in warnings and touch the connection underneath, you might get a zap that makes you swear a few times. Stupidity is not a reason to declare an object "super dangerous".

No, I just checked a Youtube video where a CRT heated in the front with a blowtorch sprayed glass out a few feet. The video may not be representative of a normal explosion not caused by frontal heating, but I don't think it's correct to call a CRT safe.

And if you dropped one on someone's head it would probably hurt them pretty bad, I guess that also means they're unsafe?

In practice the only likely way you'd break a CRT would be if you dropped it, it'll make a very loud bang but it's not going to explode like a grenade. Kids around here used to go shooting BBs at the old unwanted CRT TVs left out for rubbish collection, you could find lots of shattered screens but there was never any glass sprayed out in front of them.

Dropped CRTs were the 2nd leading cause of nerd deaths from 1992 to 1998. In response to this growing problem, in 1999 the FCC regulated CRT sales, requiring registration and three day waiting period. Though the resulting dotcom crash caused considerable economic troubles, CRT deaths have fallen to levels not seen since 1931.



Aaaanyway, we're pretty far off topic now!

Yup, monitors these days are just full of mercury and/or arsenic instead. Don't worry though, the solder's lead free - which is great for the manufacturer, because it's more likely to fail after a year or so.

CRT Pros and cons copypasta:

Pros
-Superior color accuracy
-Superior contrast, true blacks
-Better viewing angles
-Extremely low response times, no motion blur (unless it's part of the source) and less juddering
-No true native resolution, as a result it has very good "upscaling" capabilities
-Higher refresh rates are possible if you're willing to lower the resolution
-Lowest possible input lag
-Extremely long lifespans
-No stuck/dead pixels
-Highly adjustable image properties such as true contrast adjustment

Cons
-Flicker.  The higher the refresh rate the less noticeable it is. Some people are very sensitive to it and it can cause eye strain and headaches for them.
-High frequency noise.  Particularly in lower end models due to the horizontal scanning causing magnetic parts to vibrate in the 15-20 KHz range.  The sound is very annoying but luckily many older people will not be able to hear these frequencies due to deteriorated hearing.  Increasing resolution and refresh rate will increase the scanning frequency and should thus make the noise less noticeable after a certain point.  This is far more likely to be noticeable in TVs than monitors.  Personally this sound drives me mad.
-Size
-Weight
-Power consumption
-Heat
-Inferior brightness.  This can be a problem in brighter environments.
-Eye strain.  Decreases as refresh rate is increased.
-Burn in (image retention)
-Less sharp compared to an LCD running at it's native resolution.  In lower end models the difference in sharpness can be very substantial.
-Inferior signal transmission, usually analog only
-No digital "enhancements" like frame interpolation are availible
-Small sizes only
-Becomes "duller" over time as they age.  Maximum sharpness and brightness both decrease over time.
-Very few widescreen models available.  The geometry is difficult to handle.
-Most are not flatscreen.  Geometry problems exist in both flatscreen and curved screen models but are much worse in flatscreen models.
-Overscanning is generally worse
-Limited inputs/outputs
-Reflective surface causes glare and can raise effective black levels depending on ambient light
-Hard to repair if broken

To summarize, overall image quality is usually better on a CRT at the expense of convenience. Make your decision based on what you want in a display.

CRTs are not dangerous in any way.
