#183289 — Do LED monitors get weak over time, Screen size

Do LED monitors get weak over time, the brightness gets dim?

Or is the picturer better on my laptop just because it's smaller, 15.9",
and the stand-alone monitor for the desktop is 20"?

I've only noticed a problem since I've been watching some movies from
the 40's with night scenes. 

The ACER laptop is about 9 years old, and the Dell monitor I bought
maybe 10 years ago, used, at a hamfest, so I don't know how old it is**,
I have had the brightness turned all the way up from when I got it, and
it seems fine most of the time. 

The new-to-me (3 or 4 years old) Dell laptop gives a clearly better
picture. 

I don't mind buying a new one, but only if the picture is likely to be
better. 

If I do get a new monitor, would I like a bigger one, bigger than 20
even though I sit only 3 feet from the screen? 


**I can't find the model number.  Device Manager just calls it generic.
PCinfo32 only says about the graphics card.

 200 nits     A dim monitor
 300 nits     Average new monitor
 600 nits     Apple Studio Display 5K
1000 nits    Outdoor displays (visible in sunlight)

All display types dim with age.

LEDS   70% backlight intensity at 25000 hours
CCFL   25000 hours, originally white tube gives brown light
CRT    Tube loses intensity as it ages

Only a reflective display might not age.

LCD liquid crystals last a long time, but
I think eventually they get "tired".

You could have a 4K monitor at 27" or 32",
and adjust the Windows resolution. The nits rating
will tell you the initial brightness.

And there are gadgets like this. But I don't know
if the screen is flat on this. If using this, you
would probably set the Task Bar to descend, and keep icons
off the desktop. That's to take "best care" of the monitor.
This is not an LCD.

Maybe I can get a tube brightener.  I had one in 1978 and it worked
well.
