The default Display Preference options in macOS Sierra. Another feature you can take advantage of lies in setting the resolution for your display. With the Scaled option selected, you’ll see.
If you hold the shift key down at startup, OS X will reset the monitor configuration to a default value. I've added this tip to the main body of this hint, along with the reference to the MacNN.
Jul 01, 2020 McAfee Agent 5.6.0 and later report the Mac operating system as either 'macOS' or 'MAC OS X'. Resolution: A design change occurred in McAfee Agent 5.6.0 regarding the reporting of the Mac operating system. McAfee Agent 5.5.x reported the OS Type value only as Mac OS X. McAfee Agent 5.6.0 and later report the macOS Type as macOS or MAC OS X.

Nov 12, 2019 Have the same issue. Have dual Dell 3K monitors and after upgrading to mac OS Catalina one monitor frequently looses its default resolution after waking the system from sleep. This is a pain because of my setup accessing the switch on the mac mini is awkward and I always put it to sleep rather than shutting it down. Feb 27, 2017 This tutorial will teach you how to set the internal monitor resolution to 1920x1080 or 1280x720 (Full HD). This will work with any version of OS X, including El Capitan.

Hell Yes ! Tried the 'Classic' version of Quake 1.30 under OS X.1, threw my monitor into an unuseable mode as well. Ok -> I got drastic; after a re-install of 10.1 didn't fix the issue https://spirefloor.weebly.com/how-to-scan-for-wireless-networks-in-mac-os-x.html. (esp. after trying all the original 'tricks' to restore a useable monitor) SO - I did a TOTAL clean install. Reformatted the drive, 10.0.4 all the way to 10.1 That fixed it & took plenty of time to do. And killed my address book/user prefs/dock apps & totchkes Sigh. Great tip - tho. Thanks in hindsight. p.s. Hey Apple, how bout a key combo that 'unconditionally quits the frontmost app and returns the user to the Finder (ideally in a safe monitor resolution)' for OS X ? Keying blind really sucks serious ass.

Just as a note, I am having this problem as well and am searching for whether there is a fix or not. Here is some info in case it helps us figure out the real fix: G4/400 AGP 16MB Rage Pro 704MBs RAM OS X 10.1 (obviously :^) ) Sony 17' trinitron monitor (and, yes, I need a new one anyway) --set usually at 1280x768, millions of colors, 75Hz I have found that the Display panel doesn't show all of the resolutions OS 9.1 shows, and the Hz ratings certainly aren't the same. The odd thing is that the Display menu in the top menubar does seem to show the proper resolutions and refresh rates except that it is still missing 640x480. When in the Display panel, waiting a short time seems to return the display to its prior settings (probably because of the timed save request). However, a game I ran does not do this. Luckily a CMD-Q took me out of the game and back to the prior screen resolution and desktop, but I'm worried something will leave me hanging like the author of this thread had. I'm glad I can go in through 9.1 and delete that file at least, but it'd be nice to have a bit better display handling. I look forward to other info others might be able to find or figure out!
If you have more than one machine and they're networked, you can fix this by using a remote control program such as Timbuktu or (my choice) OSXvnc. The nice thing about OSXvnc is that it can be started from the command line. So when I blacked my monitor (by selecting a too high refresh rate, which instantly took effect permanently - argh!), I did the following: SSH'd in from my iBook and launched OSXvnc from the command line (OSXvnc.app -rfbport portnumber). Then I quit the SSH session and launched my VNC client and connected to the now remotely-controllable dead screen Mac. The last step is too open the Displays panel, select a valid refresh rate, and watch the screen come back to life on the Mac. Saves a reboot and keeps that all important 'uptime' stat going ;-). -rob.
If you hold the shift key down at startup, OS X will reset the monitor configuration to a default value. I've added this tip to the main body of this hint, along with the reference to the MacNN forum where it was first discussed. Adding this comment just to move the hint to the top of the 'What's New?' box. :-)
I ran into the 'out ot scan range' problem on my new G4 733 which is hooked up to my old Apple 20' monitor. It took me three hours of researching on the net and trying all sorts of things until I found the trick about deleting the com.apple.windowserver.plist trick. The 'boot with shift key down' solution seems the most elegant solution, but here are two other things I discovered that may help in other scenarios: 1. you can hold dowm command-S on startup to get into console mode before the screen resolution settings are applied. 2. of all the CDs that came with my G4, only the OS 9 Install CD allowed me to get to the desktop where I was able to move the com.apple.windowserver.plist file to another location.
besides /Library/Preferences/com.apple.windowserver.plist I also needed to trash /Users/[yourusername]/Library/Preferences/ByHost/ com.apple.windowserver.biguglynumber.plist then it worked fine. Otherwise the resolution changed back to the invalid just before the finder finished loading..maybe because of Jaguar, or because I had auto-logon enabled. cheers
I have a G3 with unkown speed, ram, HD etc. IT Department just put 10.3.1 on it and after I did security updates, isntalled IE 5.3, Mozilla 1.7.x and the machine restarted itselft the display has never come back up. i've tried to ctrl-s on startup, holding down shift as well to no avail. does anyone have any ideas ?

Changing the resolution of your display
Your Mac automatically chooses a default resolution that is optimal for your display. To change the resolution:
Choose Apple menu > System Preferences.
Click Displays.
Select Scaled, then select any of the four or five scaled resolutions, depending on your Mac model. With scaled resolutions, text and objects can appear larger and more visible, or smaller to provide more space for windows and apps.
If you're using an external display to extend your desktop, you can choose a preferred resolution for each display. To see additional resolutions for the external display, press and hold the Option key while selecting the Scaled button.
Mac Os X Reporting Incorrect Default Resolution For Monitor Computer
If you're using an external display to mirror your built-in display, your Mac optimizes for whichever display is selected in the ”Optimize for” pop-up menu. Allow your Mac to choose the best resolution for that display, or select Scaled and choose a different resolution.

When mirroring your displays, you can optimize for the external display instead of your built-in display
Using apps with a Retina display
If an app looks different than you expect on your Retina display or high-resolution external display, try opening the app in low-resolution mode:
Mac Os X Reporting Incorrect Default Resolution For Monitor Screen
Quit the app.
Open the Applications folder.
Click the app once to select it, then choose Get Info from the File menu.
From the Get Info window that opens, select the checkbox labeled ”Open in Low Resolution.”
Close the Get Info window and open the app again.
Some apps that work best in low-resolution mode or that work only in low-resolution mode will have this mode already turned on, and in that case you might not be able to turn it off. The app developer might offer an update that includes support for the Retina display.
Using Boot Camp and Windows with a Retina display
Mac Os X Reporting Incorrect Default Resolution For Monitor Windows 10
Boot Camp supports resolutions up to 3840 x 2160.
When your Mac is using the Apple-supplied Windows Support Software, Windows starts up with the maximum dpi (pixels) it supports, which is 144 dpi, or 150-percent magnification. As a result, items on the display appear small, with a lot of space. You can use the Windows Display control panel item to adjust this setting in Windows.
