Today the top tier golf simulation software is now capable of showing high resolution realistic courses that enable you to feel like you are on the tee box of a championship course. But since the highest resolution projectors have a native 16:9 widescreen aspect ratio, it can be confusing when you want the same experience on more squarish projection screens such as 4:3, 1:1 or a custom aspect ratio. So how do you get the maximum resolution possible from your projector when using a non-native resolution or aspect ratio? For example, how can you use a native 4K 16:9 projector with a 4:3 aspect ratio impact screen and enclosure without having a compressed picture that doesn’t look realistic?
Every projector resolution comes with its native aspect ratio and pixel density. The highest resolution projectors such as 4K UHD which has 8 million pixels, and 1080p which has 2 million pixels all use a 16:9 aspect ratios. But these projectors also have the highest pixel density that enables you to see the details of leaves, water hazards, and clouds. So, if you have a 4:3, 1:1 or other shape enclosure you will want to rescale the image to take advantage of the high pixel density of the widescreen imaging chip. But how do you do this without distortion? We’ll show you an easy way to do this automatically, as well as the alternative approach if you have an older projector.
According to a national survey of golf simulator buyers and owners, the most important feature is the ease of setup. In 2024, there is now a projector that has an integrated camera that recognizes the size and shape of your impact screen and will automatically reconfigure your image to perfectly fit your screen. The new BenQ AH700ST is a short throw 1080p projector that has motorized zoom and focus, but also special software designed to recognize different impact screens. Once it recognizes your screen aspect ratio, it will take care of all the calculations below to determine the optimum resolution, aspect ratio, and digital corrections such as keystone if the projector is mounted off-center. This system maximizes the pixel density of the DLP 1080p imaging chip to produce a perfectly tuned image on your screen in just 10 seconds or less.
Most golfers who are connecting a PC to a projector can take advantage of graphics card drivers and their ability to create custom resolutions. With customized resolution, you can get the highest pixel density on any aspect ratio while avoiding the disadvantage of image distortion.
Here’s an example of the equation to figure out the maximum resolution for your setup if you are trying to use a 3840 x 2160 (4K UHD) projector to display in 4:3 mode. As shown below, put the 4 divided by 3 on the left, with native height (in pixels) of 4K resolution as the denominator after the equal sign. Next, we have 4 times 2160 divided by 3. The result is 2880, which means the maximum resolution of 4:3 aspect ratio projection through a 4K UHD projector (native aspect ratio 16:9) is 2880 x 2160. This resolution could be translated to around 6.2 million pixels, which is lower than the native resolution of 4K UHD, i.e., 8.3 million pixels. While the resolution for non-native aspect ratio projection is lower than the native one, the pixel density is the same as it is in its native mode – preserving the crisp details and realistic intent the software designers put into the course.
Here is a handy table you can use to figure out what is the best resolution from your projector on popular non-native aspect ratio screen shapes:
|
4K (3840x2160) | WUXGA (1920x1200) | 1080p (1920x1080) | WXGA (1200x800) |
16:9 | 4K (3840x2160) 3840x2160 | WUXGA (1920x1200) 2133x1200 | 1080p (1920x1080) 1920x1080 | WXGA (1200x800) 1422x800 |
---|---|---|---|---|
16:10 | 4K (3840x2160) 3456x2160 | WUXGA (1920x1200) 1920x1200 | 1080p (1920x1080) 1728x1080 | WXGA (1200x800) 1280x800 |
4:3 | 4K (3840x2160) 2880x2160 | WUXGA (1920x1200) 1600x1200 | 1080p (1920x1080) 1440x1080 | WXGA (1200x800) 1066x800 |
1:1 | 4K (3840x2160) 2160x2160 | WUXGA (1920x1200) 1200x1200 | 1080p (1920x1080) 1080x1080 | WXGA (1200x800) 800x800 |
If you use a widescreen impact screen that is the same aspect ratio as your projector, every single pixel is used. But if you want the most realistic image on a non-native aspect ratio, you’ll want to set up the desired aspect ratio through graphics card settings. This will result in the same amount of detail in each pixel, but avoiding image distortion that could really hamper the realism of your golf sim experience. In other words, you’ll get the same realism and details as a native widescreen image – but you won’t see as much to the left and right of the fairway on the screen.
