- Acer X1230PK DLP projector
- 10m VGA lead
- Dell netbook
- Cordless USB mouse
- Old Paintshop Pro Software (just about any photo software should be ok)
- Ikea 70x70cm Stave Mirror
- 50" Projection screen mounted on 6mm MDF
- Selection of bolts, angle brackets, hooks and 4 turnbuclkes
To generate a 50" image the projector needs to be 6'6" away from the screen. The only way to acheive this in a normal room is to use a mirror set at 45 degrees. The mirror needs to be fairly rigid otherwise the geometery of the image will be distorted. Initially, I wanted to buy a projector with a short throw range which would allow it to have been mounted directly over the screen. However, I spotted this one at almost 70% off so I was happy to put the extra work in.
Here's a list of what to look for in a projector:
- Brightness of at least 2,000ansi Lumens. Most DLP projectors easily meet this.
- A 4:3 or 1:1 aspect ratio. Widescreen is great for movies but not so good for gaming on.
- XVGA (1024x768) resolution or better. Budget projectors are 800x600 which is ok at a push. Also make sure your computer can output the correct resolution.
- Options to flip (mirror) the image if you are planning on a set up with a mirror.
- Options to rotate the image 180 degrees
- Vertical Keystone correction this allows you to make adjustments if the angle of the mirror/projector isn't perfect.
- Noise level under 30dB. Depending on the setting used mine is 28-33db and I wouldn't want it to be any louder.
- Some form of manual zoom for fine tuning the image to fit the screen.
