Considerations when selecting a projector
The decision over what projector to choose falls into a few categories such as budget, space limitations and preference. For our turnkey packages Golfsim Australia will always suggest the best projector for your application.
Short Throw vs Standard throw. For a golf simulator generally we would regard short throw as something between a throw ratio of 0.7 to 0.9, anything lower than this we would regard as very short throw or ultra short throw. The throw ratio is the distance the projector lens is to the screen divided by the width of image it will produce. In this sense a standard throw we would say is between 1.0 and 1.2. Anything larger than 1.2 is generally not suitable.
Laser vs Lamp
Laser is always the preference over a lamp based projector, it has at least 20,000hrs vs a typical 3,000hrs, so it produces a better image over a long period of time without needing to replace the lamp. This saves money but more importantly saves hassle and means a better image more often.
Resolution, lumens and contrast
At the moment a Full HD or a WUXGA projector is the best all round performer. This means approximately 2million pixels. A 4K projector will produce 8million pixels about. This however doesn’t translate to an image that is 4 times better. Other factors such as contrast and lumens also need consideration. We always recommend at least 5,000lumens brightness. All of these also depend on the budget of the project.
The general goal is to get the image close to an aspect of 16:9 or 16:10. If it is close to this we can use the horizontal and vertical corner correction that comes with our Panasonic projectors. If too far out we can choose a resolution that resembles 4:3 aspects. Often we will preference the corner correction on the projector because not all apps may favour various resolutions.
