Do you want to change the way your Waveshare display looks and feels? A couple of adjustments can make a huge difference. If this is your first time setting it up, or you simply want to enhance the performance, the following steps outline how to maximize your display.
1. Modify the Settings in the Display
Are you using an HDMI display?
Ensure that the resolution, refresh rate, and configuration in the config.txt file corresponds, with the capabilities of your device. For example, use a 7 inch screen with 1024x600 resolution, 60Hz, as your default screen.
On a DPI interface display?
Displays that run on the DPI666 interface have their refresh rates capped at 60Hz. Make sure that your Raspberry Pi GPIO settings are properly configured to run the DPI display without any glitches.
2. Increase Accuracy in Touchscreen Interaction
If your display has a capacitive touchscreen, make sure that the I2C interface is properly configured. A correctly set up I2C connection with the touchscreen allows the device to utilize its full potential.
3. Balance Between RAM and Frame Buffer Size
This one is about hitting the balance.
Frame Buffer Settings: Increasing the frame buffer may consume more RAM but will render more fluid graphics.
GPU Memory Allocation: Be certain that the RAM allocated to the GPU on your Pi is sufficient, especially when using high-end graphics applications.
Both of these settings can be changed in the configuration options of the Raspberry Pi.
4. Keep Drivers and Firmware Up to Date
Using the most recent drivers and firmware always keeps everything running smoothly and frequently improves performance.
Install the Right Drivers: Don't forget to download the official driver files from Waveshare that are specific to your display.
Firmware Updates: Look for updates that improve performance for new features on Waveshare’s website or through their GitHub Repo.
5. Choose the Right Interface
The interface matters. DPI is typically faster than SPI, providing better graphics and screen refresh rates. Therefore, if you want better performance, choose a screen that has DPI support.
Glimmers of Hope
Improving your Waveshare display is as simple as a few adjustments. With the proper configuration, you are guaranteed to achieve clear images, quick response touchscreen functionalities, and fluid touch interactions.
