“My experience with rain or Shine has been outstanding. They were super helpful and quick to respond to any problems I had”
0.496:1 Ultra Short Throw
A FULL SIZE IMAGE FROM UNDER FIVE FEET
At a 0.496:1 throw ratio the ZH451ST throws a large picture from very close to the screen, which is the whole game in a garage or basement bay. It also keeps the projector out of the ball flight path and off the back of a golfer's swing, which is where longer throw projectors cause trouble.
30,000 Hour Laser
NO LAMP TO EVER REPLACE
The laser light source is rated for 30,000 hours. At three hours a day that is well past twenty years, so there is no lamp cost to budget for and no gradual dimming halfway through a season.
4,200 Lumens
HOLDS UP IN A NORMALLY LIT ROOM
Impact screens absorb a lot of light and most sim rooms are not blacked out. 4,200 lumens keeps the picture bright and the color honest on a full size screen without needing to kill every light in the room.
Low Input Lag
BALL FLIGHT THAT KEEPS UP WITH YOUR SWING
16.7ms at 1080p60 and 8.4ms at 1080p120, with refresh support from 24Hz to 120Hz. Well under what a player can perceive between impact and the ball leaving the screen.
From Our SimSquad
WHO THE ZH451ST IS FOR
This is the one we point at when the room is short and the budget is real. Half the screen width of throw distance, a laser that outlives the bay, and enough brightness that you do not have to black out the room. It is 1080p, and on an impact screen that matters far less than people expect. If the bay doubles as a media room, step up to 4K. Otherwise this does the job.
What is the Optoma ZH451ST?
The ZH451ST is a 1080p Full HD laser short throw projector built for tight rooms. 4,200 lumens, a 0.496:1 throw ratio, and a laser light source rated for 30,000 hours. It weighs 6.6 pounds and measures about 10.8 by 8.5 by 4.5 inches, so it mounts easily and does not dominate the ceiling.
It replaces the ZH400ST in Optoma's golf simulator lineup, with the same ultra short throw approach and a longer rated laser life.
Why Choose the Optoma ZH451ST?
Straight framing: this is a 1080p projector, not 4K. That is the trade that keeps it affordable, and for a lot of sim builds it is the right one, because on an impact screen at normal viewing distance the resolution difference is far less obvious than the brightness and throw difference.
Choose the ZH451ST if your room is short on depth and you want laser reliability without stepping up in price. Choose a 4K unit instead if you also use the bay as a media room, or if you are running a very large screen where the extra resolution starts to show.

Frequently Asked Questions
It has a 0.496:1 throw ratio, so it sits roughly half the screen width back. Optoma rates it for screens from 30 to 300 inches diagonal with a projection distance range of about 13 to 130 inches. Send us your room depth and screen size and we will confirm it before you order.
No. It is native 1080p Full HD at 1920x1080, and it accepts HDR10 and HLG sources. If you want native 4K in a short throw Optoma, look at the ZK431ST-B or the 4K400STx and we can talk you through the difference.
Optoma does not publish lens shift for this model, and the zoom is fixed. It does offer keystone correction of plus or minus 15 degrees horizontally and vertically. That covers normal install variation, but if your mount point is well off center from the screen you want a projector with optical lens shift instead.
No. Input lag is 16.7ms at 1080p60 and 8.4ms at 1080p120, with refresh rate support from 24Hz to 120Hz. Both figures are well below what a golfer can perceive between striking the ball and seeing it launch.
No. This is a laser projector rated for 30,000 hours, so there is no lamp to replace and no consumable to budget for over the life of the bay.
Yes, sold separately. At 6.6 pounds it works with our RoS Ceiling Mount or a floor enclosure such as the SwingShield. Tell us your ceiling height and we will confirm the right mount.
