Viewsonic VX2835wm auto image adjust is greyed out

Try Right Clicking on a empty space on the desktop and select Properties. Click the Settings Tab and go change the screen resolution. The higher the resolution, the smaller the icons. Normal resolution is about 1024x768, but you can make the icons even smaller by increasing the resolution.

If you can't get into the screen resolution that way, turn off the computer and boot up into safe mode.

Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode option and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal.

When the computer boots up click Start/Control Panel or Start/Settings Control Panel and look for Desktop or Appearance and Personalization.
Look for Screen Resolution or open the desktop and click the Settings tab. Make the resolution higher to make the icons smaller. Normal is 1024x768 but you can make it higher.

In Windows 7 just click Start and in the search box type: Screen Resolution. Look up at the top for the returned search results and click on Screen Resolution. Go in and set the resolution higher.

After you change the resolution reboot and let windows go into it's normal boot up mode.

Click Start/Control Panel and look for Appearance and Personalization. Open the Screen Resolution. Adjust your resolution and see if that does it for you. Normal resolution is 1024x768 but you can also give it a higher resolution.

You can also get there by clicking Start, then in the search box type resolution. Look at the top for the returned search results and click Adjust Screen Resolution.

This must be because you have a widescreen monitor or because you have set a screen resolution that's too low for anything.
Most programs ask for a screen resolution higher than 1024x768 (which they rarely actually need) to install.
So you can change yours to that value (or higher) for the installation and if it distorts your display, set it back to the original value later.

After setting the resolution to 1024x768 or higher, run the installation and it should proceed with no problems.

It is possible that the video driver cannot support 1440X900 resolution.
Try installing the latest video driver and then try the higher screen resolution.

Make sure the video driver has been installed.
Go to Start - Control Panel - Display - click on Settings tab and change the Screen Resolution, Start with a resolution 1024X768 with 32 bit color. Increase the Screen resolution higher if required to suit your needs.

Right click on desktop choose properties when the Properties window opens set the resolution to say 1024x768 32 bit, or 1280x1024 32 bit, reboot.

You most likely have a wide screen and the screen resolution needs to be adjusted to suit the monitor.
Go to the Control Panel - Display and adjust the screen resolution until you get a normal image and correct screen aspect screen ratio. Start with a screen resolution of 1024X768 and gradually increase it until you get an image that suits your screen.

Right click on desktop, choose properties from the pop up menu, in display properties choose the settings tab and set the resolution using the slider to 1920×1080 which is your monitors optimum resolution.

I guess the video board or logic board is having problem.

These are the allowable resolutions and refresh frequencies for your monitor. 1280 x 1024 @ 60, 75 Hz 1024 x 768 @ 60, 70, 72, 75 Hz 800 x 600 @ 56, 60, 72, 75 Hz 640 x 480 @ 60, 75 Hz 720 x 400 @ 70 Hz 1280x720 is invalid but I see that you were having problems at 1024x768 which might mean the refresh timing was wrong. Make sure the monitor tab in the display properties (advanced) is correctly set with 'hide modes that this monitor cannot display' so that the display is locked to the valid frequencies and resolutions. If all else fails look at the game .ini configuration settings. You might be able to set a compatible mode there. Or run the game in a window.
