I'm trying to plug an external screen on my 2010 macbook pro 15", but when I set the maximal resolution, 1920*1080, the image seems a little constrained, and a big black vertical bar appear on the external screen. Here is a picture of it.
When I move my cursor from my macbook to the screen, the cursor goes straight from the edge of the MBP to the visible part of my wallpaper on the external screen.
When I set up a lower resolution, the problem goes away, but the display is then a little blur, because it's not the native resolution of the external screen.
Does anyone have any idea what I can do to have a good display ?
Thanks.
Edit
- I tried various frequencies with no success.
- I followed this post that seems really close to my problem: Mini DisplayPort to VGA adapter and Widescreen (FullHD) Monitor with no success. Deleting this
/Library/Preferences/com.apple.windowserver.plistdidn't fix the display. - This bug only appear with my MBP. Other colleague with same generation MBP have no problem to use this screen at 1920*1080. But I get this problem only with this screen and no other.
- I tried to use another VGA <-> MiniDisplay, same result. Tried to use a DVI <-> MiniDisplay port, same result.
I'm pretty stuck on this one. Do you think I might call Apple?

Try this:
• Go into Displays Preferences > Check Mark the box for "Show displays in menu bar"
• Under the resulting icon in the menu bar, drop the menu and set "Number of recent items" to 10.
• Click the menu again and you should see a list of recently used timings/formats. Multiple 1920 x 1080 might appear, switch to one or the other and it might just fix your issue.
Also:
In Displays Preferences > Displays > “Options” tab/button near the top of the window and make sure the “overscan” box is checked.
It would be helpful to know if you're trying to run 1080i or 1080p, and what model of your external display is.
