Fine-Tuning: Adjusting The Graphics Card And LCD Panel

Once all the components work together properly, all you have to do is adjust the LCD panel and graphics card to get the best picture. In practice, this means tweaking contrast and brightness. Only a few TFT monitors are set out of the box for maximum possible luminous efficiency, so subsequent fine-tuning can enhance both color and contrast enormously. In our case, adjusting brightness and contrast led to a much better display, enabling us to run the projector even in a sunlit room.

Adjusting the graphics card driver, in this case an ATI Radeon 9700 Pro.

Here brightness is set to maximum.

The homemade projector can also be used for presentations; given the right settings, customers will be amazed!
