Aspect ratio problem with external display

[yjchua95]

Hello all.

I just purchased an Asus 16:9 display at 1920x1080.

On my 15" MacBook Pro, I have problems with it.

With the Asus connected, I somehow can't use 1920x1080. Every time I select that resolution, it keeps telling me that the usable resolution is 1680x1050 (my MBP's native resolution at 16:10) and on the Asus, there's two black borders on either side. So in other words, I can't get full HD resolution on the Asus.

Is there any way to overcome this problem?

Thanks in advance.

How are you connecting the display to the macbook?

Is it a Thunderbolt/MiniDP to VGA adaptor? If so, try using an adapter to DVI/HDMI.

What are you using for a connecion? HDMI, DVI? I find that using HDMI or DVI cables will render/permit different Aspects and Resolutions. Also the settings play a big part of my output on a 27" Samsung.

I'm using a DVI cable. Funnily enough, it doesn't have a HDMI port.

The DVI cable doesn't?

The DVI cable doesn't?

Meaning? Using DVI won't have 1920x1080 capability? Oh gawd…..so if that's true, it means the HD capabilities of the monitor are now useless.

Go to System Preferences—>Displays

Make sure "Mirroring" is unchecked. This will allow you to select individual display resolutions.

Also if you're using HDMI, consider disabling "Overscan compensation" as well.

Never mind then. I was hoping to be able to select individual display resolutions with mirroring on. Oh well…...
