Hi all,
I just connected a monitor to my MacBook running Mojave. The monitor is a 1080p one and is about 31 inches big. MacOS detects it as a 71 inch monitor putting the resolution to 1080p makes the text very blurry.
I have tried to change the resolutions and try a different cable but none of those fixed it.
Hi AppsForLife,
It sounds like you are using the resolution set for the TV. You should be able to see more options if you set the resolution for a monitor instead of a TV. You may need to refer to the manual for the TV model you have.
Get help with video issues on external displays connected to your Mac
"If images or text on your display appear pixelated or blurry, check these things.
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.
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."
Have a great day!

Good afternoon AppsForLife,
Welcome to the Apple Support Communities!
I understand you are trying to connect your MacBook to an external monitor. Is this a computer monitor or a HDTV? What ports are you connecting to? The resources below provide general information about connecting to an external display. You may need to refer to the user guide for your monitor or contact the manufacturer for additional guidance.
Use external monitors with your Mac
About overscan and underscan on your Mac, Apple TV, or other display
Use your TV as a display with Mac
Take care.
Hi Joseph_S.,
That is correct, I am connecting to an HDTV via it’s HDMI port. I am using the under scan feature to make sure the screen fits but the issue I am having is the text is blurry.
MacOS detects wrong screen size.
