Has there been any discussion about connecting a VGA monitor to Teensy?
(It seems "vga" is too short for the search)

Is there any library for this?

Or at least a way to send single pixel commands (position, color)?
 
Out of curiosity, exactly what are you wanting to connect to the Teeny? Generally, the answer is the Teensy is underpowered for the job (not enough memory, too slow of a clock speed to pump out a full screen of data 30-60 times a second).

There are small monitors (1-3") out there that are I2C, SPI, or with direct pin connections that the Teensy can drive, but if you wanted a full size monitor, you might be out of luck. It may be better to go with something like a Raspberry Pi or Beagle Bone Black that have the specialized graphics processing unit, faster clock speed, and more memory to drive hdmi displays (R-pi can also do composite video, neither can do VGA). However, for VGA, you likely would need a hardware translator from HDMI/composite video.

For status and the like, I've used a 0.96" dig-ole OLED display (color 96x64 OLED: http://www.digole.com/index.php?productID=882, mono 128x64 OLED: http://www.digole.com/index.php?productID=528). They also make 1.3" OLED and 2.7" LCD modules that use the same programming interfaces.

Adafruit does sell a RA8875 board (https://www.adafruit.com/products/1590) that you can connect to a 5" 800x480 screen (https://www.adafruit.com/products/1596). They also sell a gamedunio 2 with a 4.3" screen (480x272): https://www.adafruit.com/products/1654

If you don't need lots of speed the 4D systems board kjn linked to is a great answer and easy to program. I've used their products before with a serial port connection to a Teensy for everything not display related. Worked great.
