Acer B296CL - 2560 x 1080
I've tried three different cables.
1. Mini DisplayPort -> DVI
The Linux/Windows machine connected to the very same monitor uses DVI to DVI. I thought, "Hey, that looks crisp, and DisplayPort's supposed to be fancy, so this sounds pretty dope."
I booted up my new Mac Mini--it displayed! It displayed in 1920 x 1080. It looked pretty silly. 2560 wasn't available in Displays no matter what weird hotkey tricks I used to try and force it.
"That's okay. It'll look better when I restart; OS X just hasn't recognized the resolution yet."
Little Apple loading screen (gray apple on black, progress bar) starts up... comes close to finishing...
Using this cable displays nothing but black after that screen, then a no signal sign. The boot up displays fine--but stretched wide, so I don't think the cable is faulty, and it can't be loose.
2. HDMI -> HDMI
Went to the nearest Mac store (third party), guy recommends me an HDMI to HDMI cable. I was looking for a Mini DisplayPort to DisplayPort, but the HDMI cable's all they've got. I figured that nothing looks good on HDMI, but I might as well try. Also, the 2011 Mac Mini they had in the store was hooked up HDMI to HDMI and looked fine.
System Preferences/Displays recognized the correct resolution, but the dock was slammed to the bottom of the screen where it was completely invisible, as was the toolbar. Everything's pixelated and bloated. I had to blindly click to get to the top left Apple menu and shut down.
3. Mini DisplayPort -> DisplayPort
System Preferences/Displays recognizing my monitor as an Acer B296CL at 2560 x 1080; the resolution is perfect. Everything's appears where it needs to be.
It looks awful. Looks like something out of a dusty library with crusty keyboards or a poorly lit hospital running a pirated copy of Vista. The font rendering is jagged as hell--the art itself is scratchy, and this is pretty bizarre to me, seeing that I used to run a Hackintosh that used this same exact monitor and had none of these issues. I've unplugged and replugged both ends--no difference. It's in there.
I don't think it's an issue of my eyes. Windows 10 font rendering looks bad on this monitor--but not this bad. Xubuntu looks perfect. Also, the 2013 iMacs at my university's computer lab look nowhere near this choppy.
This guy needed a VGA cable to fix these issues. I don't have a VGA port on my monitor.
This guy needed a special script to force his Mac to run RGB mode. He also had to disable rootless mode. Man, I already have a computer running off of crap I found on github.
How do I tell if my Mini's in RGB mode?
Is the graphics card just weak?
Is there another cable I should try, or something I might've missed? How do you hook up your Mac Mini?
