White images too bright

White objects have no contrast. Washed out. Gamma/Brightness/contrast (hardware and software) function as designed, but do not resolve issue.

Try plugging in another working monitor into the monitor output - if results are the same then the problem lies with your video circuits in your all in one. Hopefully it is under warranty - if not you are screwed because those all in one units have nothing but proprietary parts and are very costly to replace/service. If the external monitor works fine then the problem lies with the display or screen of your all in one.

The brightness and contrast can be adjusted on the monitor itself with the help of buttons on it.

It might be that the CFL lighting tubes on your monitor have failed, in which case they need to be replaced. Borrow a screen to try on your computer to test if it is in actual fact the your screen that is faulty. This is normally fixed by a computer technician! If it is under warranty return it!

My monitor stays white it wont show any display


Hi,
black-icon.gif This icon indicates the BRIGHTNESS control, more properly called BLACK LEVEL. It adds or subtracts an offset, or bias, into the red, green, and blue signals. This control should be adjusted so that black picture content displays as true black on your monitor. Misadjustment of this control is the most common problem of poor quality picture reproduction on computer monitors, video monitors, and television sets. Later in this document, I will explain how to set this control properly. The setting is somewhat dependent upon ambient light. Modern display equipment is sufficiently stable that frequent adjustment is unnecessary.


picture-icon.gif This icon indicates the CONTRAST control, preferably called PICTURE. It applies a scale factor (gain) to the red, green, and blue signals. It affects the luminance (proportional to intensity) that is reproduced for a full white input signal. Once BRIGHTNESS is set correctly, CONTRAST should be set for comfortable viewing brightness.

The gamma can be controlled through Video Card utility which can usually be accessed by going to display properties.

Depending on your video card software you may be able to right click your desktop, select properties, select settings tab and then choose advanced, towards the bottom. In there you may find a tab called Monitor and under that tab you may or may not (depending on your video card software) be able to adjust your color correction settings(gamma & brightness & contrast).

. Right click on the desktop and then select Properties

2. Click on the Settings tab and then click on the Advanced button.

3. Click on the Color Correction tab and you will see settings for Brightness, Contrast, and Gamma

Cannot change the brightness


to adjust brightness levels you might want to modify ONLY the brightness, contrast and gamma settings. Others might mess up your colors or god knows what. You can also set up the GPU's brightness settings by going to the gpu's control panel, usually opened by right clicking the desktop and selecting your video card's control panel option. Then adjust the brightness, contrast and gamma options to suit your needs. Hope that helps!

Optoma EP732H Projector - Image is Whitewashed


Hi tourblack

I wouldn't think that this is a lamp issue , as the lamp will make the picture fade away in brightness and wouldn't look white washed.

Check if the brightness is set to 50% and the contrast on 50% as well.

This could be a colourwheel that is in need of replacement.

Image adjustment functions


SHARPNESS - The function is to adjust sharpness of capturing images. CONTRAST - The function is to adjust contrast (distinction between light and dark) of capturing images. SATURATION - The function is to set color depth of capturing images. GRADATION - In this function, you can select the brightness of an entire image. It is suitable when you want to add a brighter effect to a bright object (Hi Key) and a darker effect to a dark object (Low Key).
