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!

The website of a hardware magazine projected on a wall - the brightness and image display result solely from fine-tuning the graphics card driver.

  • Hi,
    I'm a 12 year old and I just got this projector working. If you live in the bay area then I recommend you go to Weirdstuff that is where I got all my parts for all under $46

  • just looking into this idea and was just wondering what the implications would be to have the lcd screen supported away from the glass of the projector thus aiding the cooling of the screen ?? Say a 2 to 3cm gap? would this affect the picture quality or would the screen still need the same amount of cooling as it does on the screen. As you can tell by the questions i havn't made one but seriously thinking about it. also ... !! woulld there be an option of other video inputs to the screen ie .. Phono jack rather than laptop / pc?
    Cheers for the info if you respond.
