This is the coolest thing you can do with your screen!

NegativeScreen

This handy little app lets you make your screen inverted so when you're in bed or in the dark, it will be easier on your eyes and less distracting to the person next to you.

If you want to read all about why naval and jet fighter instrument displays use the color red more than any other color, read here:

The Rods and Cones of the Human Eye

When combined with the Infra-red theme, it makes for a very eye-friendly night mode:



Read the readme.txt in the app, there's about 11 different ways it can render a negative screen.

 

Oh, cool. I use cloudfire's work on my tablet to get negative display, but I'd been looking for one for the PC as well. Thanks a lot.
How do I +rep?

 

oohhhh thats amazing, i really love it! you can try to modify in negative screen with ctrl+fn+alt i =)

 

Nice find there, I run negative screens alot but using commercial software from one of my video editing suites

 

That's awesome, I'm gonna play with it now lol.

 

I always liked this demonstration:
NTSC Video - Whassit all mean anyway?

 

I used AlienAdrenaline to create a Night Mode sequence of actions that activates NegativeScreen via command line to put it directly into inverted red mode and enable the infra-red theme.

What's cool is that when I end Night Mode (ALT + WINDOWS KEY + H), it remembers the previous keyboard lighting theme.

I pinned the shortcut to my Start bar and now it's really easy to go into and out of Night Mode. I use it on an almost nightly basis!

Here's my .conf file that takes the screen directly to inverted red mode:

Code:

# comments: if the character '#' is found, the rest of the line is ignored.
# quotes: allow to place a '#' inside a value. they do not appear in the final result.
# i.e. blah="hello #1!" will create a parameter blah with a value of: hello #1!
# To place a quotation mark inside quotes, double it.
# i.e. blah="hello""" will create a parameter blah with a value of: hello"

#Predefined keys
# You can use the following modifiers: alt, ctrl, shift, win
# and a key from http://msdn.microsoft.com/en-us/library/system.windows.forms.keys%28v=vs.71%29.aspx
# You can either use its textual representation, or its numerical value.
# WARNING: if the key is not valid, the program will probably crash...

#Matrices definition
# The left hand is used as a description, while the right hand is broken down in two parts:
# - the hot key combination, followed by a new line, (this part is optional)
# - the matrix definition, with or without new lines between rows.
# The matrices must have 5 rows and 5 columns,
# each line between curved brackets,
# the elements separated by commas.
# The decimal separator is a dot.

Just copy and paste that code into a negativescreen.conf text file, be sure to back up your old one!

 

This is just what I needed!!
