Display on a monitor is not fully used. What should do?

I recently bought a Mac mini (end of 2014)

OS X 10.11.5 (15F34)

I use a Samsung 19 inch monitor via mini display port to VGA.

But the screen is not fully used (black on both right and left of the picture)

When I go to about this mac > display, this is show 13.9 inch (800 x 600). I changed the resolution of 1280 x 1024 through the display preferences. But it is still not working and this mac > display, shows always 13.9 inch (800 x 600). The image is blurred.

Help, please...

You may need to buy a graphics card in order to use a different port on the computer.

Check the display to see if there are other options of the signal may use another cable.

A more recent model computer should be able to use a modern with Thunderbolt screen

connections; Some cables with ends adapter for use with older screens may work

If the display can be used in this way. Not all of the same works if an adapter may adapt to the form.

• Apple Mini DisplayPort adapter: Frequently asked questions (FAQ) - Apple Support

While I have two Mac Mini computers, one is a late 2005 and the other end 2012;

both can use an HDMI adapter for a 19 inch Samsung works for these at full resolution.

Mini-Display port to HDMI it works; If not, using lightning.

One of my screens use one of these cards:

Apple Mini DisplayPort to DVI adapter

Some display models require pilots who would be obscure and not included with

OS X; I have another Samsung that turns, it is supported but you must use a third-

part control panel app in the old OS X 10.5.8 and OS X 10.9.5. The X OS

controls brightness and resolution are limited without it.

{Since the new Mac Mini is more beautiful with a movie theater 20 inch aluminum, it's what}

He has; the older Mini OK with a Samsung 19 inch (square), and it uses

control software for OS X settings cannot. Most recent can use Thunderbolt.}

Not sure if your screen is oldest of those who may need a separate control software.

There is a updated firmware for Mini Display Port to VGA (himself):

On the Mini DisplayPort to VGA adapter firmware update - Apple Support

If you see not all possible display resolutions in displays preferences

It may be due to the absence of a favorite graphics card. Or a longer display limit.

• About the Mini DisplayPort to HDMI - Apple Support adapters

You may need the machine support site to test technical research view if you

not a page printed with line info specifications said. Several different adapters

are available; You can even use a digital TV (limits) as screen.

The technology of the adapter and display need to better match those of the Mini.

Older tech display should be supported within the limits. Connections and drivers.

PS: See if the update of the firmware of the adapter you have, will allow him to work.

If the adapter is an Apple product, it would be able to accept the firmware.

Good luck!
