笔记本电脑甚至一些台式机显示器现在都能够自动调节屏幕亮度。他们试图平衡可读性、电池寿命和眼睛疲劳。
不幸的是，有时自动(Automatic)亮度最亮的亮度不够亮，这就是为什么您想知道如何将屏幕亮度推到最高的原因。
“比最大值更亮(Brighter Than Maximum)”是什么意思(Mean)？
在我们进一步讨论之前，重要的是要弄清楚“比最大值更亮”在这种情况下的含义。我们不是在谈论以某种方式破解您的屏幕以从中获得更多亮度。相反，这是为了通过仅在一个地方将亮度设置为最大来从显示器中获得最大的亮度。
当大多数人问这个问题时，他们想让他们的笔记本电脑屏幕比 max 更亮，但在本文中，我们还将研究台式机显示器甚至电视的解决方案。
手动将亮度滑到(Slide Your Brightness)顶部(Top)
如果您使用的是外接显示器，请使用显示器上的控件来查找亮度设置。然后将该设置推到尽可能高的位置，或者推到您想要的亮度级别。此设置独立于任何基于软件的亮度设置。
在笔记本电脑上，您通常可以通过按键盘组合来调节屏幕亮度。寻找旁边带有向上和向下箭头的太阳图标。通常，您必须按住 Fn 键（功能键），同时点击这些键之一（例如 F2 键）以使屏幕变亮或变暗。
此功能独立于您的操作系统，并且硬连线到笔记本电脑的固件中。这意味着无论您运行的是什么软件，您都可以随时使用这些键调整笔记本电脑的屏幕亮度。
调整(Adjust)您的操作系统亮度(System Brightness)和颜色设置(Color Settings)
您可以通过操作系统手动控制计算机的亮度，但前提是您的显示器支持。在大多数情况下，这仅适用于集成笔记本电脑显示器。
例如，在Windows笔记本电脑上，您可以通过单击任务栏最右侧的“网络(Network)”、“声音(Sound)”和“电池(Battery)”图标群进入操作中心，然后通过向左或向右拖动亮度滑块来更改亮度。(Action Center)
在使用 macOS 的Mac上，您可以通过单击计算机屏幕右上角的控制中心图标来执行相同操作。(Control Center)但是，使用外部显示器时，您会看到这些滑块在使用外部显示器时显示为灰色。
使用色彩管理(Use Color Management)校准您的显示器(Your Display)
还值得使用Windows(Windows)和 macOS中的内置颜色校准工具，以确保正确调整您的屏幕。可能您的问题根本不是亮度，而是显示器校准不佳，导致在您使用它的环境中难以阅读。
1. 按Windows Key + I 打开系统(System)菜单。
2.展示(Display)应该是第一类；选择它并向下滚动显示(Display)页面，然后选择高级(Advanced)显示设置(Settings)。
3. 现在为显示器 1(Display 1)（或您要修复的任何显示器）选择显示器(Display)适配器属性。
4. 现在打开色彩管理(Color Management)选项卡并选择色彩管理(Color Management)。
5. 打开高级选项卡。
6. 选择校准显示。
从这里，按照颜色校准向导中的说明进行操作。
更改您的显示适配器设置(Display Adapter Settings)
不同的显卡制造商都有自己的软件包，可以控制显卡与显示器交互的各个方面。Nvidia有控制中心(Control Center)，AMD有 Radeon Software。
在“Display > Brightness和颜色”下，您会找到一个亮度级别滑块。即使显示器的亮度设置为最大，您也可以进一步推动此滑块。这可能会增加一些额外的亮度。
禁用自适应亮度
如果您的显示器支持自适应亮度，您可以禁用此功能。在Windows 10中，转到Settings > System > Change Brightness Automatically并关闭设置。如果您没有看到此选项，则表示您的显示器首先不支持该功能。
关闭(Turn Off)黑框插入(Black Frame Insertion)或可变刷新率等
功能
许多显示器现在具有各种有助于提高运动清晰度或平滑度的功能。不幸的是，其中一些功能也会损害亮度。其中最主要(Chief)的是BFI或黑框插入(Black Frame Insertion)。
该技术在内容的每个真实帧之间插入一个完全黑色的帧。为什么？这个想法是模拟CRT（阴极射线管(Cathode Ray Tube)）屏幕的脉冲和衰减。平板显示器（例如LCD和OLED）由于其“采样和保持”特性而遭受污点运动。他们完美地保持整个图像，直到下一帧到期并立即切换。我们如何感知屏幕上的运动和跟踪运动会产生模糊，而BFI是在平板上创建清晰运动的有效方法。
不幸的是，BFI也大大降低了图像亮度。正如您可以想象的那样，在一半的时间内显示黑屏可以将显示亮度降低多达 50%！
一些提供 VRR（可变刷新率(Variable Refresh Rate)）的电视禁用局部调光来实现它。如果没有局部调光区域，图像的对比度会大大降低，并且整体亮度可能必须非常低才能防止图像褪色。关闭 VRR(VRR)可能会在视频游戏中引入屏幕撕裂，但它会解决亮度和对比度问题。
禁用Eco 模式(Eco Mode)或调整电源设置(Adjust Power Settings)
一些显示器和电视机的菜单中有“Eco”模式。这降低了屏幕可以显着变暗的底线，并降低了背光工作方式的其他方面，这些方面可能导致图像更暗。
这确实显着降低了功耗，但生成的图像可能很暗并且有一点闪烁。这些生态模式下的最大亮度水平远低于标准电源选项。更重要的是，最低亮度可能确实很低。在某些电视(TVs)和显示器上，您可以在显示系统偏好设置中调整最低亮度，因此您可能希望保持生态模式，但让屏幕比默认设置亮一点。
使用 F.Lux 等第三方软件
您可以下载和安装的一些第三方应用程序可以帮助您找到更高的亮度或以其他方式帮助优化颜色、亮度和对比度在屏幕上的显示方式。F.lux应用程序( F.lux app)可能是最好的例子，您可以免费下载。该应用程序用途广泛，但它的主要用途是减少图像中的蓝光量，与一天中的时间同步，据说可以减少眼睛疲劳并帮助睡眠。
打开 HDR
如果您有HDR显示器，则可以激活HDR以在游戏、看电影和桌面环境中使用。HDR显着增加了显示器的最大亮度，并应导致显着更亮的显示。
1. 打开开始菜单(Start Menu)。键入 HDR 设置(Type HDR Settings)并在出现时打开它。
2. 必要时选择正确的显示器。
3. 在Use HDR(Use HDR)右侧，将开关切换到 On 位置。
如果您的笔记本电脑屏幕支持HDR ，如果您想在电池电源上使用此功能
，您可能需要将电池选项设置更改为优化电池寿命。(Battery)
将亮度推至最大值以上(Pushing Brightness Above Maximum)的潜在缺点(Downsides)
虽然在“手电筒模式”下运行一段时间不会让显示器着火，但最大限度地提高亮度会对屏幕产生长期影响。首先(First)，如果您使用的是OLED，您只想在非常短的时间内以高亮度运行。OLED图像残留仍然是一个问题，并且在最大或高亮度水平下更容易发生。
如果您使用的是LED LCD，则无需担心图像残留。但是，过多地增加亮度会使您的对比度变得更差，并且可能会在您的显示器上显示“背光渗色”，即屏幕边缘无法与边框很好地密封。
为笔记本电脑、智能手机和平板电脑用户提高亮度的最大缺点是它真的很耗电。除了Wi-Fi或带有精美灯光的笔记本电脑键盘等功能之外，屏幕亮度还会在您通过Snyder Cut之前耗尽电池电量。
或者，尝试(Try)使您的环境变暗
虽然在某些情况下，让屏幕尽可能亮可能是唯一的解决方案，但通常更容易使您的环境变暗或移至更暗的环境。有时问题只是您的屏幕相对于光源的角度错误。稍微调整角度或移动光源，您将毫无问题地看到屏幕上的内容。
另一方面也是正确的。当事情太亮时，您无法阅读屏幕。一些最新的 Android 手机为阳光下的可读性提供了极高的亮度，但如果你这样做太久，这会导致手机热通知和电池没电。所以最好搬到阴凉处。
How (And Why) To Make Your Screen Brighter Than Maximum
Laptop cоmputers and even some desktop monitors nоw have the ability tо аutomatically regulate screen brightneѕs. They try to balance reаdability, battery life, and eуe strain.
Unfortunately, sometimes the brightest that Automatic brightness will go just isn’t bright enough, which is why you’ll want to know how to push your screen brightness as high as it will go.
What Does “Brighter Than Maximum” Mean?
Before we go any further, it’s important to clear up what “brighter than the maximum” means in this context. We are not talking about hacking your screen in some way to get more brightness out of it. Instead, this is about getting the most brightness out of your monitor that it can produce by setting the brightness to the max in one place alone.
When most people ask this question, they want to make their laptop screen brighter than max, but in this article, we’ll also look at solutions for desktop monitors and even televisions.
Manually Slide Your Brightness to the Top
If you’re using an external monitor, use the controls on the display to find the brightness settings. Then push that setting as high as it will go, or to your desired brightness level. This setting is independent of anything brightness setting that’s software-based.
On a laptop, you can usually adjust the brightness of the screen by pressing a keyboard combination. Look for icons of a sun with an up and down arrow next to it. Usually, you’ll have to hold the Fn key (function key) while tapping one of these keys (such as the F2 key) to brighten or dim the screen.
This function is independent of your operating system and is hardwired into the firmware of the laptop. That means you can always adjust your laptop screen brightness with these keys, regardless of what software you are running.
Adjust Your Operating System Brightness and Color Settings
You can take manual control of your computer’s brightness through your operating system, but only if your display supports it. In most cases, this is only true for integrated laptop displays.
For example, on a Windows laptop, you can go to the Action Center by clicking on the Network, Sound, and Battery icon cluster at the far right of the taskbar, then change brightness by dragging the brightness slider left or right.
On a Mac using macOS, you can do the same by clicking on the Control Center icon at the top right of the computer screen. However, using an external display, you’ll see that these sliders are grayed out using an external display.
Use Color Management to Calibrate Your Display
It’s also worth using the built-in color calibration tools in Windows and macOS to ensure that your screen is tuned properly. It may be that your problem isn’t brightness at all, but that the display is poorly calibrated, making it hard to read in the environment that you’re using it.
1. Press Windows Key + I to open the System menu.
2. Display should be the first category; select it and scroll down the Display page and then select Advanced display Settings.
3. Now select Display adapter properties for Display 1 (or whichever display you want to fix).
4. Now open the Color Management tab and select Color Management.
5. Open the Advanced tab.
6. Select Calibrate display.
From here, follow the instructions in the color calibration wizard.
Change Your Display Adapter Settings
The different graphics card manufacturers have their own software packages that control various aspects of how the graphics card interacts with the display. Nvidia has Control Center, AMD has Radeon Software.
Under Display > Brightness & color, you’ll find a brightness level slider. Even if your monitor’s brightness setting is at maximum, you can push this slider further. This may eke out a few extra lumens of brightness.
Disable Adaptive Brightness
If your display supports adaptive brightness, you can disable this feature. In Windows 10, go to Settings > System > Change Brightness Automatically and turn the setting off. If you don’t see this option, it means your display doesn’t support the feature in the first place.
Turn Off Features Like Black Frame Insertion or Variable Refresh Rate
Many displays now have various features that help improve motion clarity or smoothness. Unfortunately, some of these features also hurt brightness. Chief among these is BFI or Black Frame Insertion.
This technology inserts a completely black frame between every true frame of the content. Why? The idea is to simulate the pulse and fade of CRT (Cathode Ray Tube) screens. Flat panel displays (such as LCD and OLED) suffer from smeary motion thanks to their “sample and hold” nature. They hold the entire image perfectly until the next frame is due and switch instantly. How we perceive motion and track movement over the screen creates blur, and BFI is an effective way to create crisp motion on flat panels.
Unfortunately, BFI also takes a significant bite out of image brightness. As you can imagine showing a black screen half of the time can reduce display brightness by up to 50%!
Some TVs that offer VRR (Variable Refresh Rate) disable local dimming to achieve it. Without local dimming zones, the image has considerably worse contrast, and the overall brightness may have to be quite low to prevent a washed-out image. Turning VRR off may introduce screen-tearing in video games, but it will solve brightness and contrast issues.
Disable Eco Mode or Adjust Power Settings
Some monitors and televisions have an “Eco” mode within their menus. This lowers the floor of how dim a screen can get significantly and tones down other aspects of how the backlight works that can result in a much dimmer image.
This does significantly reduce power consumption, but the resulting image can be dim and have a bit of flicker. The maximum brightness level in these eco modes is much lower than the standard power option. More importantly, the minimum brightness may be very low indeed. On some TVs and monitors, you can tweak the minimum brightness in the displays system preferences, so you may want to keep eco mode but let the screen get a little brighter than the default setting.
Use Third-party Software Like F.Lux
Some third-party apps you can download and install can help you find more brightness or otherwise help optimize how color, brightness, and contrast display on your screen. The F.lux app is possible the best example of this and you can download it for free. The app is quite versatile, but its main use is to cut down on the amount of blue light in your image, synced to the time of day, which can supposedly reduce eye strain and help with sleep.
Turn On HDR
If you have an HDR monitor, you can activate HDR for use in games, while watching movies, and for your desktop environment. HDR increases the maximum brightness of a monitor significantly and should result in a significantly brighter display.
1. Open the Start Menu. Type HDR Settings and open it when it appears.
2. Select the correct display if necessary.
3. On the right side of Use HDR, toggle the switch to the On position.
If your laptop screen is HDR support, you may want to change the Battery options setting to Optimize for battery life if you want to use this feature on battery power.
Potential Downsides To Pushing Brightness Above Maximum
While you won’t set your monitor on fire by running it in “torch mode” for a little while, maxing out the brightness can have long-term effects on your screen. First, if you’re using an OLED, you only want to run at high brightness levels for very short amounts. OLED image retention is still a problem and happens more easily at maximum or high brightness levels.
If you’re using an LED LCD, there’s no real concern about image retention. However, increasing the brightness too much will make your contrast much worse and can reveal “backlight bleed” on your monitor, where the edges of the screen don’t seal well with the bezel.
The biggest drawback to bumping up the brightness for laptop, smartphone, and tablet users is that it’s a real battery hog. More than features like Wi-Fi or laptop keyboards with fancy lights, screen brightness will drain a battery before you get through the Snyder Cut.
Alternatively, Try to Darken Your Environment
While getting your screen as bright as possible might be the only solution in some cases, it’s usually easier to darken your environment or move to a darker one. Sometimes the problem is simply that your screen is at the wrong angle relative to a light source. Adjusting the angle just a little or moving the light source, you’ll see what’s on the screen without issues.
The flip side is also true. When things are too bright, you can’t read your screen. Some of the latest Android phones offer extreme brightness for sunlight readability, but this results in a hot phone notification and a dead battery if you do it for too long. So it’s best to move to the shade.
