The short answer

The EIKI EK-308U is a WUXGA lamp projector rated at 6,000 ANSI lumens with a 1.07–1.75:1 throw ratio. To fill a 10.5 × 8 ft (4:3) impact screen from its native 16:10 frame, the lens sits about 13′ 6″ from the screen, and that screen would see roughly 60 foot-lamberts — bright enough to tolerate some ambient light. Listed at $1,825 from Shop Indoor Golf.

Good fit if

  • You have a long room and can mount it well behind the hitting area
  • Your room has some ambient light, or you run a large screen
  • You need lens shift to line the image up without tilting the projector
  • You run a 4:3 or square screen and want more of the chip used (16:10 native)

Look elsewhere if

  • Your room is short — a standard-throw lens needs more distance
  • You don't want to replace lamps
  • You can't mount it about 13′ 6″ from the screen

Throw distance for simulator screens

Simulator screens are usually 4:3 or square, while most projectors are 16:9 or 16:10. To fill a squarer screen, the projector's full frame is set so its height matches the screen height; the extra width is masked in software. That means the throw distance depends on the projector's native frame width, not the screen width.

ScreenFull 16:10 frame widthLens-to-screen distance
10.5 × 8 ft (4:3)12.6 ft13′ 6″ – 22′ 1″
12 × 9 ft (4:3)14.4 ft15′ 5″ – 25′ 2″

14 × 7.9 ft (16:9)14.0 ft15′ – 24′ 6″
FOREference calculationDistance = throw ratio × full frame width. Frame width = screen height × 16:10 when the screen is squarer than the projector. Try your own screen.

How bright will it look?

Brightness on the screen is what the golfer sees. We convert the rated lumens into foot-lamberts (fL) for each screen, counting only the share of the frame that lands on the screen, and assuming a screen gain of 1.0. Real results are lower in eco modes and as the light source ages.

ScreenFrame on screenBrightnessWhat that means
10.5 × 8 ft (4:3)83%60 fLbright enough to tolerate some ambient light
12 × 9 ft (4:3)83%46 fLgood in a dim room
8 × 8 ft (1:1)62%59 fLbright enough to tolerate some ambient light
12 × 7.5 ft (16:10)100%67 fLbright enough to tolerate some ambient light
14 × 7.9 ft (16:9)90%49 fLgood in a dim room
FOREference calculationfL = rated lumens × share of frame on screen × gain ÷ screen area (sq ft). Cinema reference is roughly 14–16 fL in a dark room.

Resolution and aspect ratio on a sim screen

The seller lists WUXGA (1920 × 1200) with a native 16:10 frame. On a squarer screen part of the frame is unused, so the effective resolution drops.

Light source and running

A lamp gradually dims and eventually needs replacing; budget for a spare if you play daily.
