Brightness of the monitor screen changes when a picture is taken, the final picture looks blurr. Is there any solution?

You never should use the picture you see on the monitor of the camera. Not one camera has a calibrated screen. And the brightness is changed very easy in the setup menu.
To test if your camera shoots good pictures, select AUTO on the mode dial. Shoot some pictures and look on the PC or just print them.
Your camera has so many settings, that over rule the brightness when you switch to it, like + and - 2 EV setting. But when you chose for A, P, S, or M, the pictures can be to dark or to bright, if you dial in the wrong settings. So don't evaluate the pictures on the monitor. Only use the histogram on your camera to see if you have a correct, to dark or to light picture.

Hi,

Dear User...

You can adjust the brightness and contrast of your monitor to improve the readability of text and to make digital pictures appear more like they'll look when printed.

To improve the results when adjusting the brightness and contrast settings for your display, use Display Color Calibration. (Display Color Calibration helps you adjust these color settings and others.) For more information about calibrating your display color in Windows, see Calibrate your display.

The way you adjust brightness and contrast varies and depends on your specific display.

• Brightness and contrast buttons on the front of the monitor. Some monitors have brightness and contrast controls on the front and use the standard symbols shown in the following image.

• On-screen menu. You can change the brightness and contrast settings for some displays by using an on-screen menu, and then setting the brightness and contrast in the resulting menu. Many times, you can view the on-screen menu by pressing a button-possibly labeled Menu-on the front of the monitor.

Thanks....

Actually, the problem isn't with the drivers. Right click on the battery icon in your system tray. Select "Power Options" (NOT Power4Gear eXtreme). On the right panel, select "Adjust the display brightness." Then, select "Change advanced power settings." Scroll down and open up the "Display" box. The options that are affecting your screen brightness on battery are "Allow SmartDimmer to reduce my brightness after," "Have SmartDimmer reduce my brightness by," and "SmartDimmer full-screen video mode." Playing with the percentages in these boxes will affect how your screen brightness adjusts itself. To get my screen to stop re-brightening itself, I changed "Allow SmartDimmer to reduce my brightness after/ On Battery:" to 100%. I then changed "Have SmartDimmer reduce my brightness by/ On battery:" to 0%. Finally, I set "SmartDimmer full-screen video mode/ On battery:" to Maximum Power Saving. This should solve your screen-rebrightening problems even with the 163.44 drivers (I use those too). Please Rate.

On screen menu should have brightness and contrast, and other adjustment.
You can get user manual here:

I had same problem, go to the menu and under PICTURE BOOST there are 6 options choose BRIGHT FRAME and turn it OFF. Corner white blob is gone.

Finally found out that the Optquest monitor is an viewsonic brand monitor and finally downloaded the manual.

i beleave on auto, the a75 has auto focus, there is a 1/2 second focus time before the picture is taken, enough to blurr the picture

Also, if you changed the screen resolution to something your monitor will not support you will get the same thing happening.

no can do. you monitor is dead in the water.
lost of focus, and intensty. all point to one thing.
by the way, do you have the correct video driver installed???

this is CCD prob..
