i got a 10 on my gateway 20 LCD (one year old), and a 6 on my 17 Acer CRT (4 years old), the monitors are non calibrated just a little twich in every way, errors came from redish-orangesh and bluish-greenish narrow bands, am 50 and wear reading glasses around +1 diopters, but took the test without them, so, NOT BAD at all.

Cool test! I got a 0 - Highest score for your gender and age range: 1520

 

it only took less than 10 minutes. Also used a dell ultrasharp monitor.

 

Also I'm not sure if this was posted:

 

FACT: 1 out of 255 women and 1 out of 12 men have some form of color vision deficiency.

Take the online color challenge, based on the official FM100 Hue Test by X-Rite.

 

I thought this fact was surprising!

A calibrated display would never have both it's brightness and contrast cranked all the way up. The brightness is always set to 100% to ensure the monitor is displaying all of the color range it can, but the contrast is usually set to zero and then moved up until a grey ramp just barely starts to show the darkest swatch on the ramp. If it's set too high you start to blow out some details.

 

Jeff, I thought i'd read most of the stuff on calibration but that brightness thing doesn't sound familiar. So the brightness for an LCD monitor should always be set at 100? When I've run through my calibration tools, I don't think it's ever had me set it to 100. Why would that be?

I may have omitted some important information when I typed that. Sorry. I can't recall the context in which I wrote that. Depending upon whether you are talking about an LCD or CRT the calibration and profiling process is slightly different. It's also different if your LCD has a contrast control, which most do not. If you are using a CRT, the CONTRAST is set to 100% and then reduced so that the calibration software's indicator falls within the range determined by your calibration target you set up (white point, gamma, Luminance). One of the next steps will be to then adjust your BRIGHTNESS to also fall within the target range your software indicates. On a CRT this is done when you adjust the individual R, B and B guns to adjust the white point, but on most LCDs you would use the contrast control to adjust this as they don't have individual R, G, B controls.

 

Hope that makes more sense.

Sorry, I'm pretty dense. Let me explain my particular situation. I just got a new computer as well as monitors (went with a pair of Viewsonic VP2365wb's based on your suggestions regarding IPS monitors over the TN variety). I haven't calibrated yet but will be soon, using ColorMunki. They are LCD monitors and seem to have pretty good onscreen controls (including both brightness and contrast).

 

When I run ColorMunki, as I recall it will either let me go through the advanced setup where it has me set brightness and contrast, etc. and then goes into creating the actual profile. Or I can just use my current screen settings and skip straight to the profiling. If I go with the former, I'm pretty sure (again, going off of memory) that my brightness will NOT be set to 100 based on ColorMunki's recommendations (I have an Eye-One which I believe had the same results).

 

So my questions are 1) should I NOT go through the ColorMunki step that has me adjust brightness/contrast and rather leave my brightness at 100 and skip right to letting ColorMunki create my color profile? and 2) Why would the calibration software have me set my brightness below 100 if 100 is always optimal?

I've not used my ColorMunki yet, so I don't know if they made any changes to the software from XRITE's EyeOneMatch software. I'll have to install it and check it out. You will always want to go through the full process each time, just in case your display settings got changed accidentally. You don't want to create a profile based on an improperly calibrated display.

 

Do whatever steps the software tells you to do. You set the brightness and contrast to 100% temporarily until directed by the software to change it. You adjust both brightness and contrast (depending on the display) so that you have a display with a luminance that matches a defined standard and so that you get the best dynamic range from the display. If your display was set to 100% for both, it's very likely if you looked at a black to white ramp you would see that the white end of the ramp would all be white with very little segmentation.

Just to be 100% clear then (sorry), I should go through the steps and do what it says - ie. my brightness shouldn't necessarily be at 100% for optimal color?

 

-Brodie

 

Correct. Once you get into the app and you have any questions, let me know. I'll try to install the ColorMunki app and see how it works. Been on my to do list for a while.
