Correcting the Color of Computer Screens with Adobe Gamma

How to scientifically adjust your monitor:

Step 1: Use the method I provided to correct the black field first:

The following method is very accurate. Regardless of whether Adobe Gamma is working or not, the results of the calibration are accurate because only R, G, B=0,0,0 is used as a pure black for correction. Pure black is not affected by Gamma.

a. The ambient light level is set to the same level of image processing at ordinary times. Don't be too bright. Avoid reflections on the monitor too much.

b. Need a black desktop. Go to "Display Properties", select "Desktop", change the color to black, and confirm it's R, G, B=0, 0, 0. If there are many icons on the desktop, drag the icon to the lower border of the screen to avoid interference.

c. Find the "Contrast" button on the display (actually it adjusts the maximum brightness) and turn it to maximum. (If the maximum is too dazzling, you can also reduce it appropriately.)

d. Find the brightness (brightness) button on the monitor. In fact, it adjusts the black field. If the brightness setting is too low, the details of the dark part of the image are not displayed correctly and the dark part becomes dark. If the brightness setting is too high, some of the display's contrast is wasted, and the picture is not really black and appears gray.

Now, first adjust the brightness to maximum.

e. With the "Vertical Zoom" button adjusted, the scanning range of the monitor's electron gun is narrowed and black appears above and below the screen. This is the area not scanned. This is the blackest display.

f. If the previous step can distinguish between areas not scanned and areas scanned, go to step i. Otherwise go to the next step.

g. Use the button to move the scan area vertically so that the unscanned area appears on the top of the screen. If you can distinguish between areas that have not been scanned and scanned areas, go to step i. Otherwise go to the next step.

h. Some monitors cannot display unscanned areas. You can make the room completely dark, the brightness to a minimum, and then slowly increase, until the display just shines. Then slowly and repeatedly dim/light up until it is considered to be a bright spot that can just glow. After adjustment, go to step

i. For the case where it is possible to distinguish between areas that have not been scanned and areas that have been scanned, adjust the brightness button so that the scanned area and the unscanned area are just merged (brightness is just indistinguishable).

j. Black market adjustment ends. Adjust the scan area to the desired range. This concludes all.

Now that you can adjust Adobe Gamma, do not activate the brightness and contrast buttons!
If you previously calibrated your monitor with ADOBE GAMMA, now follow the steps below to do it again without resetting to the original state.

The following is a foreigner's method, not all translation, too professional, and few people can understand.

I think that's enough.

Step 2: Follow the foreigner's method to operate:

Set the picture you just downloaded to the desktop background, by centering

There are 7 small black boxes on the top of the desktop image just set. Each black box is made up of two upper and lower black boxes.

0.4% - Both of them should be totally black No 0.6% respectively - They are also black and they are not 0.8% respectively - We can see a slight difference... or not 1.0% - to have a closer look, there is a difference of 1.2% - Can see the difference, step by step to see 1.4% - can see the difference 1.6% - it is clear to see the difference

third step:

Description: Open the ADOBE GAMMA option, select Step by Step, Next... The above screen appears:
(The monitor that I calibrated in the previous three weeks does not want to calibrate again, so use his screenshot!)
What you should see is the image above. Some people may see it:
sRGB Color Space Profile

If it is not Adobe Monitor Profile, go to C:WINNT\system32\spool\driver\scolor (win XP and 2000 methods), and put all the files inside and out into other directories, and then move back again... Then Immediately re-open (be sure to be fast, do not appear Adobe Monitor Profile) ADOBE GAMMA.

Now choose the monitor phosphor Sony Dragon Pipe Trinitron, other options P22... If you know your monitor's fluorescent powder is better!

the fourth step:

1. After adjusting the above steps... see the picture below. Fill in the box with 2.5...

2. Minimize all dialogs, adjust the gray slider in Adobe Gamma... you must adjust the image on the desktop so that the 8 colors all look the same, which means you can't tell each color So far (On the brightness, don't forget the color)

3. Then click on the hook in the small box at the upper left. There will be 3 boxes for red, green, and blue. Adjust each color... Let the 8 bars on the desktop become grey!
It may be better to look farther away, and ask your friend to help look at it. This part is more troublesome! Repeat it several times!

the fifth step:

1. Adjust the monitor's color temperature: Select 6500K/DayLight. Now suppose your screen color is correct! If your desktop's graph changes, go back and adjust Aamma to the correct level

2. Some monitors don't have the same color, so select Measure/test, then select OK.. The screen will turn black and 3 frames will appear. Adjust it! Let the middle box become white so far... Confirm the exit to Adobe Gamma's screen to see if it is 6500 degrees K. If not... then go back and re-tune Aamma!

3. After the transfer, save.

This is a method that does not cost money. Of course, the best method is to buy a SPECTRO CALIBRATOR screen comparator or Kodak's IT8 standard color scale for calibration!
