You have a 4:3 screen but you are considering a WXGA projector as it matches the resolution of your new Laptops. Without incurring additional cost of changing a 16:9 screen, how can you maximize your current screen?
By projecting onto the 4:3 screen with a 16:9 image, your top and bottom half of the screen area would be wasted. To make matter worst, if you get connected to a XGA Resolution Laptop, the projected image will be even smaller than your actual screen; it shows a smaller image than the 16:9 because the left and right extreme of the pixels are ‘blocked’ off to show only 1024×768 instead of 1280×800.
It is misleading that some projector catalogues are telling you that using a WXGA Projector will give you a larger screen, but you actually end up with a smaller one.
So what are your options?
If you still prefer the WXGA Resolution, you will need to change to a larger 16:9 screen to get a larger image. The area where you install the screen must have sufficient width to cater for the increase in screen size.
A more cost effective option is actually to keep to a XGA Projector. WHY?
Without having to change your existing 4:3 screen, using a native XGA Projector will maximize the screen surface. (Not forgetting that XGA projectors are also a couple hundred dollars cheaper than the WXGA ones)
What happens when you try to connect with a WXGA Resolution Laptop? You have 2 options:
- Fix the projector Aspect Ratio at 4:3 and the projector will compress the WXGA image to fit into a 4:3 image. This method might cause some distortion in the image you are trying to project.
- Allow the projector to auto detect the Laptop resolution and adapt accordingly. What happens is the projector will block off the top and bottom of the image to show a 16:9 aspect ratio image. This however will not give you the full 1280×800, but 1024×576 pixels and the sharpness of the image will be compromised but not compromising the actual size as you will still be maximizing the full width of your screen. Consider the cost savings, it is perhaps a good trade off.
So in summary, if you would like to have a WXGA Resolution projector, it will serve you better if you change to a larger WXGA Format Screen. If not, buying a XGA Resolution projector need not necessarily mean that you cannot display a 16:9 image when required (all these while using your existing projector screen)
