Issues with resolution settings

Although many of these troubleshooting steps may apply to Mac users, they're built out specific to Windows. Mac users, please visit the Picasa for Mac Help Forum for troubleshooting assistance. There you'll find help from Google Guides and our most knowledgable users.

In order to run Picasa, you need to have a minimum computer desktop resolution of 800 x 600 and 16-bit color. If your settings don't meet this requirement, you may receive the following message: 'Picasa must have at least 800 x 600 resolution to work.' To troubleshoot this issue, please take the following steps:

Step 1: Check your desktop resolution

Make sure that your desktop resolution is set to meet the minimum requirements:

  1. Right-click a blank portion of your computer desktop.
  2. Select Properties.
  3. Click the Settings tab.
  4. Use the slider to adjust your screen resolution to at least 800 x 600.
  5. Make sure your color quality is set to at least 16-bit.
  6. Click OK.

Step 2: Check your Picasa shortcut resolution

If you've checked your desktop resolution settings and you're still seeing the error, it's possible that your Picasa shortcut resolution setting may have inadvertently been selected. Follow these steps (in Windows XP) to deselect this setting:

  1. Right-click the Picasa shortcut on your computer desktop.
  2. Select Properties.
  3. Click the Compatibility tab.
  4. Under 'Display Settings,' make sure that the 'Run in 640 x 480 screen resolution' checkbox is deselected.
  5. Click OK.

Step 3: Update your video drivers

Check with the manufacturers of your video drivers and visit their websites to check for driver updates. Outdated video drivers can also prompt this message.
