On the bottom of the monitor there are three buttons. I pressed the middle one which caused my cpu to get this red hue, esp. when i'm watching videos. How do I reverse what I just did? And what do those buttons down there do?

What model?Push the Cisco logo to start SecureEasySetup
The logo is lit with a reddish hue (the User Guide says this is
orange) when the router powers up in its factory default unsecured
state. The instructions say to press the SES button. But there is an approximately 8 second pause
between the button push and three seconds of no light, followed by the
rapid white flashing backlight that indicates the router is in SES
Probably the inverter. Have you ever seen like a hint of red color or a reddish hue on the screen? I would start with the inverter either way, it should be easy and cheap to fix and it usually is the cause.
If you have access to another monitor, check it with your computer. Pink or red hues are usually indicators of a failing backlight bulb or ccfl bulb that sits in the bottom of the display and lights up the lcd.
is it in warranty..?? if not.. do it if u r a professional..
check the following: 1) the cmos battery (above +3v)..replace with a standby n see.. 2) remove/clean dust neatly..dust is non-uniform in nature n may cause
jam/short circuitry/excess resistace n many more..resulting an increase
in heat.. 3) open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink
Compound" (available in local electronics chip level spare market)
between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it
tightly in position.. 4) the smps itself may b defective/faulty..check the outputs of smps
viz. 0v (black~ground); +12v (yellow); +5v (red, green~ps-on, violet~pg
& grey~sb); -12v (blue); -5v(white); +3.3v(orange).. the 'oscillator and error amplifier ic', or
pwm switching regulator circuit..look for defective
protector-transformer/resistance(esp 4.7k)/mosfet.. 5) ur main/mother board..see with a debug
card for mb error..may b short..look for defective capacitors(esp above
1000mfd)/mosfets..go through the mb's south bridge n the circuit lie
around atx connector....
..plz give higher priority to step3 & 4 (as listed above) CAREFULLY..
Depending on your monitor settings, you should putt all 3 colors on either 0 or 50. whichever is in the middle of the spectrum in your settings. However, when I've seen this problem on monitors, it's been a problem with the cable. Sometimes the cable is tilted, meaning some of the pins aren't connecting. In other cases, missing or bent pins can cause this too. So try to check out both ends of the video cable and adjust it accordingly.
Have you loaded the drivers which came with the monitor. This will probably allow you to change the settings.
Right click on an area of your desktop and choose properties. Look at the monitor and make sure the resolution is set to the recommended level possibily between 60 or 75 dependant on the model. Also you can get to the display card settings here and change them to suit. Dont get carried away or you can make it so that you cant see whats on the screen at all to be able to change it. Could also be that your monitor is faulty. Check with your manufacturer. It its an old telly type monitor maybe one of the "guns" have gone so you dont get the right colour mix of red green and blue. If this is the case you will need to get a new screen.
