Yesterday when I connected my laptop to my external monitor, my resolution options changed and now I only have two options for screen resolution. 1280x720 and 800x600. I'm not sure what I used to use, but everything is much larger now and not as clear. I've rebooted, unplugged and restarted and nothing has changed. My laptop display is the same, but my external monitor options changed. Any idea why? I don't think I updated anything...
MacBook Pro
I ended up opening my laptop while it was connected to my monitor and the mirrored display option appeared. I unchecked the box, closed the laptop and my desktop monitor had the resolution options back. no idea how the mirrored option got turned on... thank you thank you thank you for your assistance! I can see clearly now LOL

Uncheck:
[√] Mirror displays ... while both are active.
the name of that window is the name of YOUR display.

27-in Apple Cinema Display: native DVI resolution: 2560 by 1440
DVI displays wider than 1920 wide require more expensive Dual-Link DVI cables and adapters, all the way through.
Dual link has an extra set of three data conductors to carry the additional information required for higher resolutions.
as search for a J5create brand dual-link adapter comes up empty, but there are now some direct from USB-C to Dual-Link DVI in one adapter. they are a bit pricey. This one at US$30.99 on Amazon:

if you choose [√] Mirror displays, BOTH displays are set to a compromise resolution that both appear to be able to attain, and are refreshed with the SAME hardware display-generator, exactly in sync with each other:

Memo to readers who find this post by searching:
Under MacOS 13 Ventura: If you have multiple displays connected, but do not see the arrangement pane, Open the Lid to be able to make choices for both displays.
what model-year MacBook Pro, and what screen size and Intel or Apple-Silicon?
which LED cinema display, 24-in or 27-in?
How are you adapting computer output to display input? please mention EVERY device in the chain.
do you have the lid closed?
this article suggests you should be getting choice of displays and an arrangement pane:
Use one or more external displays with your Mac - Apple Support
.
if you uncheck that box, the displays are concatenated along an edge (that you can specify) and are treated as one big "Extended desktop".
Once you arrange them to correspond with their actual locations on your bench, the mouse moves freely across the imaginary boundary between displays, and can carry a window with it.

The problem has returned and this time regardless of if I choose main, extended or mirror, I cannot get the resolution I need.
about a month ago my display options became limited to 1280x720 and 800x600 making for very poor resolution on my monitor. i’ve tried to change the display settings on the laptop from mirror, to extended to main, but nothing I do will all me more resolution options like i used to have and this is wearing on my vision. Is there a fix for this?
Thank you.
I close my laptop and only use the big monitor when at my desk. How do I get to the thunderbolt display screen? I only see the Displays screen?
this is what my displays screen looks like
yes. I always have the lid closed
