By definition, the throw ratio is the distance from projector to screen divided by the width of the image. The throw ratio spec for any projector assumes you're using the full width of the native resolution, which isn't true for many home golf simulators. The best position for the projector will usually be roughly 4 feet behind the tee location, which makes the distance easy enough to figure out. However, the width of the simulator space is a limiting factor, and thus you can use a 16:9 or 16:10 projector to project a 4:3 image. In this case, you won't be using the projector's full image width, and for easier calculation we suggest you choose the right throw ratio using the modified formula to calculate distance and height. For the detailed formula, please see below.

If the projector is hanging on the target line, it's the safest place in the room. About 7-8 feet from the screen is sufficiently away from the screen to avoid a ball hitting a projector, and no more than 2 or 3 feet behind the player to avoid shadows. Based on this, you can measure the distance to the impact screen and the height of the screen, and then calculate the throw ratio you need. A projector with throw ratios ranging from 0.5 to 1.1 helps you put the projector where it is needed to fill the screen while being mounted safely outside the hitting area (and without casting a shadow).

Resolution is what enables you to see the details on every blade of grass and the subtle contours on the green. Full HD 1080p or WUXGA is OK, but 4K is preferred. For the best widescreen experience, a 4K projector will create an immersive image even on impact screens larger than 14 feet wide. This is especially important if you are using a system such as Foresight, TruGolf, and other simulators that support 4K output.

For the impact screen to be tall enough to accommodate the path of the ball and still fit in the typical width for a home golf simulator projection, it usually winds up as a 4:3 aspect ratio or close enough to need a 4:3 image, because that allows you to go taller, giving you more room to swing without needing a bigger room. It’s not difficult to find a projector with a native 4:3 aspect ratio, but many are lower resolution, such as XGA or SVGA. Image quality greatly increases when using a native 16:9 or 16:10 projector, with WUXGA or 4K resolutions. So as a practical matter, we suggest using a projector that has a native 16:9 or 16:10 aspect ratio, then adjusting the image to give you a 4:3 aspect ratio.

4K short throw projectors should be your first consideration. 4K UHD delivers awe-inspiring clarity and crisply defined details that enable you to see all of the minute nuances on the latest 4K golf simulator courses. It allows your impact screen to double as an amazing home theatre for movies or watching the Masters Tournament when you’re not practicing your golfing skills. On the other hand, the percentage difference in price between WUXGA and 4K isn't that significant among higher end models. If you plan to buy a single projector for both a golf simulator and home theater, the extra cost for 4K may well be worth it.

Step 1: Check if your enclosure or impact screen aspect ratio is 16:9, 16:10, 4:3, or 1:1. The enclosure or screen border should be at least 2.4 inches (6 cm). Step 2: Check the environment. Ensure the screen has enough contrast with its surroundings and turn off all room lights. Step 3: Make sure the projection fully covers all four corners and that all 12 circle patterns are within the screen, then click the Auto Screen Fit button again. Step 4: Perform a factory reset and restart the projector if the issue persists, then try Auto Screen Fit again. For detailed guidance, we strongly suggest seeing below.

BenQ Screen Fill feature allows the projector to easily switch directly from its native resolution to other resolutions and aspect ratios to best match your desired display with maximized pixel counts while avoiding image distortion. You don’t need to go into graphics card or Windows display settings, which saves time and bother. 1. Open the Advanced Menu and select the Display sub-menu through the OSD of your BenQ projector. Find Screen Fill and select the resolution you prefer. 2. Right click on your PC desktop. Select Display Settings, then confirm Display resolution is set to Recommended. 3. Select Advanced display settings. Then, change the Refresh Rate to ensure the Desktop mode and the Active signal mode match. For more details, please see below.

Step 1: Choose the highest resolution on your PC that matches your golf screen’s aspect ratio. If no option matches, please see below to create a custom resolution. Step 2: Install your golf sim software. If prompted to set a resolution, use the one chosen in Step 1. Step 3: Position the projector so all four corners go beyond the screen. This buffer is for digital correction. The more off-center the projector, the more buffer you need. Step 4: Mount the projector at the chosen distance, keeping the image as vertical as possible. Use lens shift (varies by model) or adjust ceiling mount length if needed. Step 5: Use 2D keystone to correct vertical tilt first, then horizontal tilt. Step 6: Use the corner fit function to fine-tune each corner until the image is rectangular.

A projector lamp inevitably loses brightness after each hour of use, which causes image degradation. We suggest you follow the specified lamp life hour rating as a guide to when the lamp may need replacing. For example, a projector with a 4000 hour lamp would require a lamp change once those 4000 hours are up. You can find light usage time stats in the Information page of the On-Screen-Display menu. This doesn't mean the lamp will suddenly fail when it reaches its estimated lamp lifetime. You can continue to use the lamp until complete failure, but doing so impacts image quality.
