Golf simulator projector: 4K projectors compared.
SIM|GOLF
The impact screen is half of the picture in a golf simulator – the projector is the other half. We compared the short-throw 4K laser projectors that come up most often in SIM|GOLF projects: where each one has to be mounted, how much light it puts on a 420 cm wide screen, and whether 4K actually makes sense on impact fabric.
5 specs that really matter
- Throw ratio. Lens-to-screen distance = image width × throw ratio. It decides whether the projector hangs above the hitting area, in front of it or behind the golfer. A zoom lens gives you mounting tolerance; a fixed lens needs an exact measurement.
- Offset and lens shift. Offset tells you at what height relative to the image the lens has to sit. Optical lens shift moves the image without digital keystone correction, which costs sharpness and brightness. In a simulator this is one of the most important features, because the ceiling is rarely where the manufacturer would like it to be.
- Brightness on the screen, not just lumens. On a 420 cm wide screen the light is spread over almost 10 m². That is why we also give lux (lumens ÷ image area). As a rule of thumb, around 300–400 lx is enough in a darkened room; in a lit room or a club aim for 500 lx or more.
- Input lag. There should be no visible delay between impact and ball flight on screen. Golf-oriented projectors have low-latency modes, e.g. BenQ LK954ST: 16.7 ms at 4K/60 Hz.
- Light source. For a simulator we choose laser (approx. 20,000 h): no lamp replacements, and the image is ready the moment you switch it on.

* 4K achieved by pixel shifting (BenQ XPR, Panasonic Quad Pixel Drive). ** ANSI lumens ÷ image area 420 × 236 cm (9.9 m²). This is the maximum value: in eco mode, at the long end of the zoom and as laser hours add up, the image gets darker. Prices: PT-RQ7L per the manufacturer's price list (1 July 2026, body + lens); the other models are indicative Polish market prices, October 2026, incl. 23% VAT, converted at 4.3 PLN/EUR.

Where does the projector go?
In a typical simulator the ball sits approx. 3.0–3.5 m from the screen. With a 420 cm wide image, most projectors with a throw ratio of around 0.8 therefore end up above the hitting area or just behind it – not far back "behind the golfer". So before choosing a projector we check:
- room height: a full driver swing needs approx. 2.9–3.0 m, and the projector with its mount must not hang lower than the club's arc;
- shadow: the higher and closer to the screen axis the projector hangs, the lower the risk of the golfer's head casting a shadow on the image;
- right- and left-handed golfers: we mount the projector on the screen axis, and horizontal lens shift lets you move it sideways if needed;
- safety: a projector mounted in front of the ball (like the Optoma UHZ35ST at approx. 2 m) needs a guard against ricochets and high deflected balls.
For ceiling mounting we use the adjustable SPIDER mount, which sets the lens at the right height relative to the screen.
What the comparison tells us
BenQ LK954ST – our pick for most simulators. 5,100 lm, and its large optical lens shift (V ±60%, H ±23%) lets you fit the projector to almost any ceiling. Add low latency and golf colour modes. With a 420 cm screen it hangs 3.4–3.7 m from the screen. It is the successor of the popular LK936ST+.
BenQ AK700ST – a sensible home budget. Shorter distance (from 2.9 m), motorised zoom and autofocus. But there is no lens shift: an offset of 102.5% means the lens must sit roughly at the height of the top edge of the image. With a 420 cm screen, 4,000 lm is the lower limit and the room should be darkened.
Panasonic PT-RQ7L – professional class. 7,500 lm, motorised optics and interchangeable lenses. The choice for golf centres, lit rooms and multi-bay venues where the projector runs a dozen hours a day – but the price is several times higher.
Optoma UHZ35ST – for short rooms, with compromises. The manufacturer added a golf picture mode, and at approx. 2 m from the screen the projector hangs in front of the golfer, so shadows are not an issue. However, it has a fixed lens with no zoom and no lens shift, so the mounting position must be accurate to the centimetre. With a 420 cm screen it delivers only approx. 350 lx and needs a ball guard. We recommend it mainly for smaller screens and darkened rooms.
Does 4K make sense on an impact screen?
Yes, but the benefit is smaller than in a home cinema. At a width of 420 cm a Full HD/WUXGA pixel is approx. 2.2 mm, a 4K pixel approx. 1.1 mm. The golfer looks from approx. 3 m at a fabric with a visible weave, so the difference shows mainly in fine detail: text, lines on the green and the distant background. 4K also needs a powerful PC: smooth 4K in simulator software means an RTX 5070-class graphics card or better. And you need a screen with a smooth, dense fabric, such as PRO4K.
What about non-4K? Panasonic PT-VMZ6ST
If your screen is 16:10, consider the Panasonic PT-VMZ6ST: 3LCD, WUXGA 1920×1200, 6,200 lm, throw ratio 0.797–1.01, lens shift V +50% / H ±20%. It fills the entire 420 × 262.5 cm screen at native resolution, without masking, and delivers approx. 560 lx. 3LCD technology has no rainbow effect. The manufacturer's list price is approx. €4,900 incl. VAT.
What image size for a 420 cm wide screen?
- 16:10 (WUXGA): 420 × 262.5 cm, the projector's full panel is used.
- 16:9 (4K): 420 × 236 cm, every 4K pixel is used. On a screen 262 cm high we align the image to the bottom and mask the top approx. 26 cm. Alternatively, the screen can be made in 16:9 from the start.
That is why we choose the projector first and only then the screen size. For every SIM|GOLF project we draw a section of the room showing the projector position, mounting height and image proportions.
Summary
- Most home and commercial simulators: BenQ LK954ST.
- 16:10 screen and lots of light for sensible money: Panasonic PT-VMZ6ST.
- Golf centre, lit room: Panasonic PT-RQ7L.
- Home on a limited budget with a darkened room: BenQ AK700ST.
