Is the new monitor you just bought blindingly bright? Do you always feel like screen smearing when playing games? Don't panic! Today we will look for the hidden settings of computer LED screens. To be honest, last week I helped my neighbor’s college student adjust the monitor, and I spent half an hour fumbling around in the OSD menu—this thing is much more complicated than setting up a mobile phone!

Three Basic Settings

​​The little bump next to the power button​ ​That's the entrance! More than 50% of the monitor adjustment keys are hidden on the back of the bezel in the lower right corner. Take a certain Dell model as an example. Press and hold the five-way navigation key for 3 seconds before the menu pops up. Here’s a trick for you:​ ​Press and hold the "+" and "-" keys simultaneously​ ​, some brands will jump directly to eye protection mode.

Brightness adjustment is not about brighter, the better! According to data from the China Electronics Technology Standardization Institute,​ ​It is recommended to adjust the indoor environment to 120-150cd/m²​ ​. If your screen supports smart light sensing, quickly turn on this function - it can automatically adjust according to the ambient light, which is much more accurate than manual adjustment.

Must-see parameters for advanced players

The refresh rate is so important! Nowadays, most mainstream monitors basically support it.​ ​60Hz/144Hz/240Hz​ ​Third gear switch. A game geek friend has actually tested that by increasing the refresh rate from 60 to 144, CSGO's headshot rate can increase by 15%! But be careful, you have to synchronize the settings in the graphics card control panel.

When it comes to color calibration, the HDR settings that come with Windows are a pitfall. A friend who is a professional designer told me,​ ​It is best to use Spyder color calibration instrument + DisplayCAL software​ ​Come and adjust. If you find it troublesome, at least adjust the color temperature to 6500K, which is the value closest to natural light.

Special function secret door

Nowadays, many high-end screens are hidden​ ​Hardware-level anti-blue light mode​ ​, much stronger than software filtering. Engineers from a certain brand revealed that their eye protection mode can cut 70% of the blue light in the 415-455nm band without causing yellowing like the software solution.

The dynamic contrast function is quite controversial! Actual testing found that when watching movies with this function turned on, dark details will be blurred. On the contrary​ ​local dimming technology​ ​It’s really nice. When HDR is turned on on a machine with zoned backlight, the transition between light and dark is obviously more natural.

After-sales pit avoidance guide

Don’t disassemble the phone yourself if you encounter a flickering screen! There was a case last year where a user replaced the power supply board and burned the motherboard. The repair cost was more expensive than buying a new one. For equipment purchased through formal channels, it is safest to go directly to the official after-sales service - many brands have it​ ​Door-to-door testing service​​。

Finally, a little trivia: the service life of the monitor is related to its placement! Avoid direct sunlight and humid environment, use regularly​ ​Microfiber cloth + screen cleaner​ ​Take care of. By the way, never use alcohol to wipe it, as the coating will be corroded!

Speaking from personal experience, those fancy preset modes are basically useless. There are only three elements that really affect the experience:​ ​Gamma value, grayscale response, input delay​ ​. Next time when adjusting your monitor, remember to focus on these parameters and toss them, and you will get twice the result with half the effort!
