Settings brightness

Hi which monitor are you using? Connect a different monitor to same system to see if that monitor works correctly with that CPU with same settings or connect your monitor with another CPU which is working properly with different monitor to pinpoint exact problem first. Any monitor if gets old will have such problem. If monitor is okay then you can check if display driver is present or not by going to See how many output connections your monitor has if it has multiple input connections like display port, HDMI, DVI, etc, you can try connecting to different ports if your CPU supports to see which connection gives what type of display.
This video has partial information about display settings. You can right click on desktop and select properties and make it to default settings.

I need the picture settings for a trutech tv. For example : number for contrast .

The picture setting for any TV depends upon the taste of the viewer. Contrast is the deepness of details in black and grey level. In most TVs a 55 to 75% of contrast will give a good picture. you have to adjust the brightness level also according to contrast. It is best ot turn out colour to 0% first. Adjust contrast and brightness to get a well detailed B/W picture first. The apply enough colour to that B/W picture according to your taste. Face colour of a newsreader at studio will be the best reference to intensity of colour.OK.

Screen settings


You want to recall the factory settings. There should be an entry in your menu for this. Sometimes its clearly indicated as 'reset' sometimes it is a word that means much the same, such as 'recall'.

The numbers you posted that have a 'K' at the end are settings for the white color temperature. This is an old label from the early days of TVs. One is better than the other for graphics vs clarity. Usually you want the higher setting.

Other wise, if you can't locate the reset option. Go into each setting for Contrast, Brightness and set Contrast 50 and Brightness 100, the others affect the position of the display and how square it is. Set all those values for trapazoid, etc to 0.

Anything else you need clarification on please comment back and I will validate or correct your instincts on what is the reset option command if you are unsure about what is being displayed.
