Before you begin
You can resolve many display issues by updating the software on your Apple devices, cables, and adapters. If you can see an image on your screen, check for software updates using the Mac App Store:
- Connect your external display and any Apple video cables or adapters that you use with it.
- From the Apple menu, choose App Store.
- Click the Updates button in the App Store window.
- Install any macOS or firmware updates that are listed.
If you're using a display, hub, extender, or adapter not made by Apple, check with the manufacturer for any updates that might be available.
If you're trying to connect a 4K display or Ultra HD TV with your Mac, make sure your computer meets the requirements for using these external displays.
If your software and firmware are up to date, or if you can't see the image on your screen, try the steps below for your specific issue.
If the display image is blank or unusable
Try these steps if you don't see an image on your display. These steps can also help if the image on your screen repeatedly turns on and off (flickers), if horizontal lines appear (snow), or if the image is distorted (torn or scrambled).
These steps likely won't help if the issue is only happening in one app. If you see similar issues in only one window or app, check with the app's developer for updates or more help.
Check connections
Check the connections to your Mac and external displays:
- If you're using an Apple notebook, try connecting its power adapter.
- Make sure the external display's power cable is securely connected and that your display is turned on.
- If you're using a Mac Pro (Late 2013) make sure your displays are connected to the right ports.
- If you're using a display hub, switchbox, or 'KVM,' try connecting your display's video cable directly to your Mac instead.
- Disconnect the video cable where it plugs into your Mac, then plug it back in to reseat the connection.
- If you're using a video adapter, unplug the video adapter from your Mac, then plug it back in to reseat the connection.
- If you're using more than one video adapter to connect your display (the adapters are 'chained' together), try connecting the display using only one adapter if possible. Some video adapters can't be connected together. For example, a mini DisplayPort to DVI adapter can't be connected to a DVI to HDMI adapter.
- If your display has more than one video connection, see if using another connection on the display works. If possible, check to see if using a different display or a different adapter works.
- Try using a different cable that you know is in working order. Check with the display's manufacturer to make sure you're using the cable they recommend.
- Restart the Mac with the display connected.
Detect your display
If you're using an external display, sleep and wake your Mac to make it check for connected displays:
- Press the power button on your computer to put it to sleep, or choose Apple menu > Sleep.
- Wait a few moments, then press a key on your keyboard or click your mouse or trackpad to wake your Mac.
If you're using more than one display, and you can see the image on one of the displays, you can also use Displays preferences to check for connected displays.
Adjust video settings
If there's no image on your display, try adjusting your display's brightness or contrast. If there's still no image, or the image appears torn or scrambled, try selecting a different video resolution in System Preferences.
Adjust brightness
- If you're using an Apple Display, press the increase brightness key on your Apple keyboard. To adjust the brightness of a secondary display, press Control-F2.
- If you're using a display that's not made by Apple, check the documentation that came with your display to see if it includes built-in controls for adjusting its brightness or contrast.
Change your display resolution
- From the Apple menu, choose System Preferences.
- Click the Displays icon.
- Click Default for display. If you see more than one resolution listed, choose a resolution and refresh rate. If the display turns off when you change resolutions, press the escape key to undo the change.
If you can't change the resolution of your display because you can't see an image, restart your Mac in safe mode to reset the display resolution to defaults.
If starting in safe mode doesn't resolve the issue, reset your Mac's NVRAM and SMC to reset the video ports on your Mac to their defaults.
Check for third-party display software
If your display works only when your Mac is started in safe mode, and you have display-related software installed, check with the software's developer for updates, or try temporarily uninstalling it.
If an image appears fuzzy or blurry
If images or text on your display appear pixelated or blurry, check these things.
Check your display resolution
Make sure your display resolution in System Preferences is set to its default. If you're using a resolution that's scaled, the image might be magnified to fit the display. This can cause the image to look blurry in some apps.
- From the Apple menu, choose System Preferences.
- Click the Displays icon.
- Select Default for display.
If you use a monitor or an HDTV connected with an HDMI cable, you might see a difference in video quality if your display is set to television mode. Check your display for a 'monitor mode' setting to get the best video quality.
Retina displays
If an app you're using appears low resolution on your Retina display, check to see if an update to the app is available. Most apps have been updated to use the higher pixel densities of Retina displays.
Lower-resolution images on some web pages might also appear 'softer' when viewed on a Retina display. This is because Retina displays have a higher pixel density and not all websites use Retina-ready images.
Jun 18, 2019 AirDrop is a neat little trick you can use to quickly and easily share files of all kinds between Apple devices, including photos, videos, contacts, map location, and more. Oct 03, 2019 For example, photos appear in the Photos app and websites open in Safari. App links open in the App Store so you can download or purchase the app. If you AirDrop something to yourself, like a photo from your iPhone to your Mac, you won't see an option to Accept or Decline — it'll automatically get sent to your device. Do mac laptops have airdrop app. Apr 15, 2020 With AirDrop, you can wirelessly send documents, photos, videos, websites, map locations, and more to a nearby Mac, iPhone, iPad, or iPod touch. Share content with AirDrop Open the file that you want to send, then click Share button in the app window. Aug 16, 2019 In other words, it works a lot like AirDrop—two people with Files by Google installed can use the app to send files back and forth using Bluetooth. Cross-Platform Alternatives to AirDrop Classic network file sharing tools still work well with Windows PCs, Macs, and even Linux systems.
For example, the images below look different when viewed on a Retina display, but the same on a non-Retina display. This happens because the Retina-ready image has a higher pixel density:
If you see contrast or color issues
If your entire display image seems too dark or too bright, you can adjust the brightness and contrast from the Displays pane of System Preferences, or by using your display's built-in controls.
Adjust brightness and contrast
To adjust the brightness of your Apple display, press the brightness key or F2 key on your keyboard. You can also use the brightness adjustment for each connected display in System Preferences > Displays.
Displays not made by Apple sometimes have brightness and color adjustments built into the display. Check the documentation for your display to see if it includes built-in controls.
When you connect a display, projector, or HDTV using an HDMI cable, you might see a difference in video quality if your display is set to television mode. Check your device for a 'monitor mode' setting to achieve the best video quality.
You can also calibrate each display from the Color tab of Displays preferences to get the best color and brightness from your display.
If you see bright or dark pixels
If individual pixels on your display seem too bright or too dark, see these articles for more help:
Connecting displays with Thunderbolt 3 (USB-C)
Acer Monitor Calibration Software Mac Update
The Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter connects Mac models with Thunderbolt 3 (USB-C) ports to older devices that use Thunderbolt (10Gbps) or Thunderbolt 2 (20Gbps). For example, this is the adapter that you should use to connect your MacBook Pro to an Apple Thunderbolt Display or a third-party Thunderbolt 2 storage device.
This adapter doesn't support connections to Mini DisplayPort displays, including the following Apple adapters and displays:
- Apple Mini DisplayPort to Dual-Link DVI Adapter
- Apple Mini DisplayPort to DVI Adapter
- Apple Mini DisplayPort to VGA Adapter
- Apple LED Cinema Display
If you're using the Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter to connect to a compatible display and the display doesn't show an image, try unplugging the adapter and plugging it back in.

Most people don’t ever really bother calibrating their monitors because everything looks fine when they first set it up and so they just stick with that. I’ve also done this myself many times, but recently, I tried calibrating my monitor and found that it looked much better than what I had been used to.
Windows 7, 8, 10 and Mac OS X all have built in wizards that help you calibrate your monitor so that it’s not too bright or too dark. For me, my monitors were always super bright and I starting using a third-party program called f.lux that adjusts the color of the monitor during the night.
Once I calibrated my monitors, I didn’t need to use f.lux as often, even at night. In addition to brightness, the colors on the screen looked better after the calibration. In this article, I’ll talk about how you can calibrate your display on Windows and Mac.
Calibrate Display – Windows
To start the calibration wizard in Windows, click on Start and type in calibrate. You can also get there by going to Control Panel, clicking on Display and then clicking on Calibrate Color in the left hand menu.
This will start the Display Color Calibration wizard. Go ahead and click on Next to start the first step. The first thing it asks you to do is to open the menu for your display and reset the color settings to factory default. In my case, I just reset the whole monitor to factory settings because I wasn’t sure what settings I had already changed. If you’re using a laptop, just go through each step.
Click Next and you’ll have to adjust the gamma setting first. Basically, for all the steps, you’ll need to match the screen to the center image, which is considered the best setting. It also shows you the too high and too low settings so you can clearly see when you’ve adjusted too much.
Note that when you try to adjust the slider in the Windows program, the monitor may reset to its own default settings. Most of these settings you have to change via the monitor on-screen menu itself and not using the program (unless you’re calibrating a laptop display). You just use the program to make sure it looks like the image that is considered good.
For example, here is a picture of my Acer monitor and the on-screen settings that can be adjusted. In my case, I had to adjust the gamma value from this on-screen menu because it wouldn’t let me change it using the slider in Windows.
After gamma, you will need to adjust the brightness in order to distinguish the shirt from the suit and have the X barely visible in the background. You can skip brightness and contrast for laptop screens.
Next up is contrast. Again, adjust the setting on your monitor. For contrast, you want to set it to the highest value possible before the buttons on the shirt start to disappear.
The next screen will help you adjust the color balance. Here you want to make sure all the bars are grey and that there are no other colors present. In newer monitors, this is taken care of and if you try to adjust the sliders, the monitor will just reset to the default values, so you can just skip this part if that is happening to you.
Once you finish this, the calibration is complete. You will now be able to click on Preview and Current to see the difference between the what you had before and what it looks like now.
I would also leave the ClearType Tuner box checked before clicking Finish. This is another short wizard that will make sure the text is appearing crisply and clearly on your monitor. You basically have to go through five screens and choose which text looks best to you.
That’s about it for calibrating a Windows monitor. Between the monitor software and this wizard, you really don’t need anything else unless you are a professional, in which case you’re probably going to have a high-end monitor anyway.
Calibrate Display – Mac
For Macs, the wizard is a little bit different when it comes to calibration. It also depends on what version of OS X you are running. I have written this article running OS X 10.11.2 EL Capitan, which is the latest version.
To get started, click on the little Apple icon at the top left of your screen and then click on System Preferences.
Next, click on Displays in the list.
Now click on the Color tab and then click on the Calibrate button at the right.
This will bring up the Display Calibrator Assistant introduction screen that will guide you through each of the steps.

The Mac wizard is actually pretty smart and will remove any of the steps that your monitor cannot support. For example, I ran this on my MacBook Pro laptop and the only adjustment I could make was to the target white point. It skipped brightness/contrast, native luminance response curve, and gamma curve. If an external display is connected to your Mac, you’ll get the other options.
For target white point, you can either use the native white point for your display or adjust it manually by unchecking the box first. I found the native white point gave a better color tint to the display than what was set when the OS was installed.
Calibrate Monitor Software Free
I didn’t have an external display for my Mac, so I couldn’t get the other options like luminance, gamma, etc, but you can probably figure it out as you go through the wizard. The Admin step just asks if you want to make this color profile available for other users or not and Name step lets you name your new profile.
Best Monitor Color Calibration Software
The summary screen will give you some technical details about the current color settings for your display. OS X also has another tool called the ColorSync Utility that lets you repair color profiles, view all profiles, and calculate the RGB values for any pixel on your screen. Just click on Spotlight and type in ColorSync to load it.
As I stated earlier, most people won’t ever worry about calibrating their monitors because most of them do a pretty good job by default. However, if you are picky about how everything looks on your screen, it’s worth giving it a shot. If you have any questions, post a comment. Enjoy!
