Why The ZK608TST
The Commercial-Grade Anchor Of The Optoma 4K Lineup
The ZK608TST is the build for the largest screens and the most demanding install conditions. More brightness, an IP6X-sealed engine, lens shift, and HDBaseT extend the install reach beyond what the entry and mid-tier models can do.
6,000 ANSI Lumens
The brightest projector in the Optoma golf sim trio. Drives the largest impact screens and holds image contrast in bays with ambient light or commercial overhead lighting.
True 4K UHD
3840 × 2160 native resolution renders sharp fairway detail, readable simulator overlays, and clean tracer lines at screen sizes all the way up to 300″.
0.58:1 Short Throw
Fixed short-throw lens designed for ceiling-mount installs in commercial-depth bays. Projects 30″ to 300″ from roughly 1.2 ft to 12.3 ft.
IP6X Sealed Engine
The optical engine is IP6X dust-rated. The laser block is sealed against ingress so dust and airborne particles cannot degrade brightness or color across 30,000 hours.
30,000-Hour Laser
DuraCore laser light source eliminates lamp replacements entirely and holds rated brightness across the full life of the projector.
Vertical & Horizontal Lens Shift
Manual vertical lens shift from -106% to 116% and horizontal ±4%. Aligns the image to the screen without keystone distortion — critical on commercial screen sizes.
HDBaseT 3.0
HDBaseT input runs uncompressed 4K, control, and power over a single Cat6 cable up to 100 m. Clean rack-to-projector wiring in commercial installs and AV racks.
Dedicated Golf Sim Mode
Optoma’s Golf Sim Mode tunes color, contrast, and response for simulator gameplay — brighter blue skies, deeper shadows, natural greens. One-touch from the backlit ProAV remote.
Who Is It Best For?
- Commercial sim bays and golf studios
- Largest impact screens up to 300″
- Rooms with ambient light or overhead lighting
- AV-integrated installs needing HDBaseT
- Dust-heavy environments or high-use facilities
- Multi-bay rooms running long daily hours
Short Throw & Setup
The Pro-Grade Lens And Geometry Toolkit
Placement Flexibility
The 0.58:1 fixed short-throw lens pairs with full lens shift and four-corner correction — the toolkit you need to fit a 300″ screen into a commercial bay without distortion.
- Projection distance: ~1.2 ft to 12.3 ft
- Screen size: 30″ to 300″ diagonal
- Vertical lens shift: -106% to 116%
- Horizontal lens shift: ±4%
- Keystone: horizontal ±15°, vertical ±15°
- Four-corner correction
Installer Checklist
Short-throw 4K commercial installs need pre-planning. Confirm clearance and HDBaseT runs before mounting.
- Confirm screen width and final aspect ratio
- Verify ceiling height and bay depth
- Use the ESG fitment tool for exact mounting distance
- Plan HDMI or HDBaseT cable runs
- Plan 12V trigger and RS232 to AV rack if needed
- Test image placement and lens shift before permanent mount
What Is The ZK608TST
The Pro Anchor Of Optoma’s 4K Golf Sim Lineup
The ZK608TST is the top tier of Optoma’s purpose-built 4K golf simulator lineup — brighter, sealed, and ProAV-equipped versus the compact ZK431ST-B and mid-tier ZK521ST-B. It uses a single-chip DLP engine with a true 4K UHD pixel array, a sealed IP6X-rated DuraCore laser optical block rated up to 30,000 hours, and a fixed 0.58:1 short-throw lens.
Placement range: the ZK608TST supports a projection distance of roughly 1.2 ft to 12.3 ft and a screen size range of 30″ to 300″ diagonal. For the exact lens-to-screen distance based on your screen size and aspect ratio, run the numbers in the ESG projector fitment tool and throw calculator before mounting.
Ceiling mount notes: the ZK608TST weighs 13.89 lbs and supports 360° orientation. The chassis measures 14.72″ × 11.89″ × 4.61″ and uses a 50% post-consumer recycled plastic eco housing. Native offset is 106%. Alignment uses manual vertical (-106 to 116%) and horizontal (±4%) lens shift, four-corner correction, and ±15° keystone in both axes.
Connectivity: 2 × HDMI 2.0 inputs, 1 × HDBaseT 4K input, 2 × VGA, 2 × audio in, 1 × HDMI 2.0 out, 1 × audio out, 1 × 3D sync, 1 × 12V trigger, 1 × USB-A 1.5A, RJ45 LAN, and RS232 control. The included backlit ProAV remote ships standard.
Simulator software: the ZK608TST works with all major sim platforms including GSPro, E6 Connect, TGC 2019, Awesome Golf, and Foresight FSX. The dedicated Golf Sim picture mode is built into the projector OSD and is purpose-built for third-party simulation software.

Build The Complete Bay
Pair The ZK608TST With The Rest Of The Build
A projector is one piece of the simulator. Elite Sim Golf builds the full bay — enclosure, screen, hitting surface, launch monitor, PC, and projector — sized and shipped together so the geometry works the first time.
Pair It With An ESG Enclosure
The Eagle 12 enclosure is sized for short-throw 4K projectors with proper sidewall clearance and an impact-rated screen surface. Frame, screen, and side curtains ship together.
Build A Complete SimKit
Pre-built SimKit bundles include the projector, enclosure, hitting surface, launch monitor, and PC matched to your room size and budget. Or use the Bundle Builder to spec a custom kit.
