Black level test

Yeah I checked that out myself last night, I can see the difference in all levels, with RGB(0,0,0) the same as the background. Color gradient looks good, no banding. Also using the 215TW.

I see everything black as well, but then again, Im on a CRT 😛

really? i guess my CRT must be crap😉...i see the difference up to RGB (1,1,1), also on my 19in. lcd(DCLCD DCL9A+) i see the difference up to RGB (2,2,2)


 
Using Standard mode I see the difference between 1 and 0. 1 is just barely, almost black and 0 is as black as the rest of my screen (excluding the other steps of course)
 
I see RGB(1,1,1) as different from RGB(2,2,2) and RGB(0,0,0) is the same as the background. This is on my Samsung SyncMaster 730B on an analog connection. However, the image is about twice as good over DVI, so once I get a chance again, I'll check that out.
 
I can see only (3,3,3)->(4,4,4) here even after calibration.

A lot of LCDs can probably do it with maxed brightness but the real point of the test is to see how well it does while having a dark black level. Mine is 0.3 nits at the moment. Ideal settings are about 0.3 black and 120 white with good contrast. If you have a higher white level, you generally have a higher black level as well, so more will be revealed, but the colors won't necessarily be natural. So it's a test of contrast at reasonable brightness settings.

Assuming reasonable settings, it's a good evaluation of how well the LCD is at displaying subtle details (its contrast). This is why the Samsung 215TW excels in the photo editing category.

I can actually see some banding on my CRT, in a dark room. Not banding like LCD's, but the actual color transitions are visible as steps, not a smooth gradient. Also, my monitor is more or less calibrated, I'm not using overly bright settings.

The steps are 40 pixels wide.

I've set my brightness/contrast pretty low (0 and 80 respectively), so with the setup I normally use, I can't differentiate any of those steps, even in a dark room. If I turn the brightness up to around 50, I can see all of them, but it's like staring into the sun when I'm looking at mostly white/light web pages, and this is a CRT. I don't understand how most people can tolerate such high brightness levels. The pain.

 
i didn't "get it" till i darkened my room 😛

my budget Samsung 19" CRT displays all the transistions in steps all the way to 000 which is the same as the background

pretty subtle but noticeable ... so i gotta spend $500 to get this in a LCD
:Q

 
I can see all the different shades on my Acer TFT, on my LG CRT all the shades are the same as the background colour apart from the last couple.

I can already tell that my CRT has better colour depth though.
 
I can see down to (1,1,1) if I look very closely. This is a nice test page but I think the name is kind of misleading. It's more of a test of dark gradients and color steps than the black level (i.e. how bright pure black looks). A monitor would do well on this as long as it's 8-bit, even if its black point is bad.
 
I have an LG 203WT, 2.1" LCD display and I can differentiate absolutely no difference, from top to bottom; it's all black as can be.

Am I doing something wrong?

You have a 2.1 inch monitor? /Sarcasm off. Are you connected by analog or dvi?
 
Sarcasm off ? lol

I'm connected via DVI. Does this mean there's something wrong?

This display was advertised (sticker still attached) as having a contrast ratio of 1400:1. I somewhat brushed this aside as a marketting ploy. Could this, if this is correct, have an influence over what I'm experiencing here, with this test?
