brightness display comparison for dell d630 laptop with today's screen

The Latitude D630's 14.1-inch wide-screen display is remarkably bright (223 cd/m^2 in our Labs measurement).

Dell Latitude D630 review: Dell Latitude D630 - CNET

Wondering if this laptop needs a new screen. To me it is not bright. Not by comparison with a new laptop.

How bright is this number 223, when new compared to laptops today?

I can get a new screen for $37.

I'm used to seeing brightness referenced in "nits", but since a candela defined "candela per square meter" I guess that is the same as what you see referenced.

223 is not very bright by comparison to many displays today. If I go up to a manufactures web site and look at new laptops I often see brightness as 400, 500, even 1000 nits. Lower end system can be something like 250 to 300 nits.

So 223 is not out of the question, but especially with modern LED backlighting rather than CFL, 223 is definitely on the low side.

this site selling bulbs says the new display will be brighter than new

I dont have flicker, i do have greyishness to all the white areas. with hints of yellowness. it just looks dingy.

That's typical behavior for CFL backlit displays. As the bulb ages the output gets really muddy.

this has had a lot of use. it might be worth the effort.

You can adjust brightness on Windows Action Center but there's also hardware adjustments [key combinations] on Notebooks, I set that first with [usually] Fn + another key] then use the Windows setting. Same for Volume control.

yes, and it is at the max level. for this its fn and up down key
