Method 1of 2:

Windows

1. Right-click on your desktop. This is the quickest way to access your display controls.^[1]
2. Select "Screen resolution" (8 and 7), "Personalize" (Vista), or "Properties" (XP). This will open your display settings.
   • Windows Vista: Click "Display Settings" option in the Personalization menu.
   • Windows XP: Click the "Settings" tab after selecting "Properties".
3. Select your active display (if necessary). Select the display that you want to check the resolution for. Click theIdentifybutton to display numbers on each of your screens so that you can select the right one.
   • If you only have one display you can skip this step.
4. Note your current resolution. Your current resolution will be shown in the "Resolution" drop-down menu or slider.
5. Check if the current resolution says "Recommended". The Recommended resolution is the native resolution of your monitor. Selecting this will result in the clearest image.
   • Windows Vista and XP do not display the "Recommended" resolution. You will need to refer to your monitor's manual to determine the native resolution.
6. Change your resolution using the slider. Clicking the "Resolution" drop-down menu in Windows 7 and 8 will display the slider. Drag the slider to change the display resolution on your monitor. Resolutions other than the recommended one will result in a blurry, stretched, or squished image.
   • Selecting a lower resolution will increase the size of objects on your screen.
   • If you don't know the native resolution of your monitor, set it to the highest possible option for the clearest image.
7. ClickApplyafter changing your settings. Your screen may flicker and shut off, and then the new resolution will be displayed. You will be asked to keep the changes or revert to your old settings. If you don't pick an option after 15 seconds, the image will automatically revert.
   • If you want to keep your changes, clickKeep changes.
   • If you don't see an image after changing your settings, just wait for it to revert.

Method 2of 2:

Mac

1. Click the Apple menu and select "System Preferences". By default, OS X will choose the native resolution for your display, giving you in the clearest image. You can change this if a program calls for a certain resolution or you need to adjust the size of objects on your screen.
2. Click the "Displays" option and then click the "Display" tab. You can select the display you want to adjust if you have multiple monitors.
3. Select the "Scaled" option to change your resolution. By default, the "Best for display" option will be selected. This will set the display at your monitor's native resolution. Select "Scaled" if you want to choose a different option.
4. Select the resolution you want to use. Options labeled "low resolution" will result in a blurry image. Options labeled "stretched" will result in objects on your screen appearing wider or skinnier than normal.^[2]
   • You may be able to select resolutions higher than your monitor's native resolution. This will make objects even smaller, but can have a big impact on your computer's speed.
   • When you select a resolution, the change will take place immediately.
5. Wait if your picture doesn't appear after changing. If you don't see an image after selecting a new resolution, wait 15 seconds for it to revert. If it still doesn't revert, pressEsc.
   • If your image still won't revert, boot your Mac into Safe Mode and select a new resolution.
