Yosemite - login screen on low res

I'm still seeing the exact same problem on 10.10.1

Just like other people have posted, it did not get fixed with 10.10.1. 😟

Perhaps the problem is introduced when a machine is upgraded from 10.9 to 10.10. Fresh install makes the problem non existant.

I've tried a fresh install but that didn't solve the problem for me.

Unplugging the external HDMI-connected monitor on startup causes the resolution to be set correctly. I can then plug the external monitor in and everything looks fine, the login even moves over to the external monitor at the correct res.

The problem only manifests when starting up with the external monitor connected.

This issue still exists on my end. I am running OS X 10.10.2 beta 2. I performed a fresh install, formatted my hard drive from scratch, did the PRAM / NVRAM technique, with the same results; the login screen resolution is still too low on OS X Yosemite. I am running a MacBook Pro Retina 15", late 2013.

it work !

After resetting PRAM, it works fine.

My system is 10.10.1 on MacBook Pro Retina (Mid 2012).

Guys, I had this issue too. Solution is unbelievable, but simple: do a graphical login as root and set resolution there. That will set resolution at login screen 🙂

Enabled root, logged in and set resolution but it did not resolve the issue

For me it worked, sorry it did not for you!

I was having a similar issue... but I changed my rMBP display resolution from Best (Retina) to More Space inside of the display preferences. Once I changed it back to Best (Retina) the issue went away.

This worked for me.

Shutting down using the power button, restarting in safe mode, resetting the screen resolution and restarting the Mac normally fixed this for me.

HOW TO:

• Shut down your Mac by holding down the power button.
• Restart your Mac, and immediately after you hear the startup tone, press the Shift key (don’t press the Shift key until you hear the startup tone). Release the Shift key when you see the progress indicator below the Apple.Startup may take a bit longer than usual, but your display should begin working correctly. You Mac is now doing a Safe Mode boot.
• Choose Apple menu > System Preferences, click Displays, then click Display.
• For the Resolution option, select “Best for display.” If this is already set choose scaled and change the resolution to 'best' and then reselect 'Best for Display' again.
• Restart your Mac.

Hope this helps.

Yeah. It works for me with other settings, but i use my laptop on more space, and as root i can not choose this option.. any advice?

I'm still seeing the exact same problem on 10.10.2

I had no problems, but we used my macbook to stream through a television on an HDMI connection last week and ever since then it has been an issue. I'm going to try the PRAM reset and other ideas listed in this thread.
