How to enable Pixel Doubling for a high resolution monitor?

Pixel Doubling can make fonts more readable (larger) on a small screen with high resolution, however, there are drawbacks

• Pixel Doubling affects the entire system. Enabling pixel doubling simply draws every pixel in the desktop as a 2×2 block of pixels on the screen, making everything exactly twice the size and resulting in a more usable desktop. But this will sacrifice screen quality.
• Will need more fiddling with other appearance settings to suit your own liking.

To enable Pixel Doubling:

1. Click on Menu (Raspberry icon).
2. Select Preferences and choose Raspberry Pi Configuration.
3. The Raspberry Pi Configuration window appears.
4. On the Display tab, click on Pixel Doubling: ( ) Enable.
5. Click OK and reboot the system.

Note: After reboot, everything on the screen becomes very big. You will need to customize the appearance settings as shown below. You may want to experiment with different appearance settings to suit your own liking.

To customize Appearance Settings:

1. Click on Menu (Raspberry icon).
2. Select Preferences and choose Appearance Settings.
3. The Appearance Settings window appears.
4. On the Menu Bar tab, set Size: Medium (24x24).
5. On the System tab, set Font: to PibotoLt 8 and Mouse Cursor: Small.
6. Finally, click OK and that's it.

Note: You may want to experiment with different appearance settings to suit your own liking.
