Product Description

The BenQ TH690ST is a gaming-focused short-throw projector engineered for players who want massive screen immersion, ultra-fast responsiveness, and vibrant HDR visuals without spending flagship 4K projector money.

Part of BenQ’s dedicated Gaming Projector Series, the TH690ST was specifically built for:

• PS5 gaming
• Xbox Series X gaming
• Nintendo Switch gaming
• Small-room projection
• Living-room gaming setups
• Casual home theater entertainment

Unlike traditional movie projectors that often feel sluggish during gameplay, the TH690ST was designed around:

• Fast input response
• Large-screen immersion
• Vibrant gaming color
• Compact-room flexibility
• Console-focused performance

BenQ specifically describes the TH690ST as:

“Level up your party fun with epic gameplay.”

This makes it ideal for:

• FPS shooters
• FIFA / EA Sports FC
• Racing games

• Open-world RPGs

BenQ also specifically confirms the projector is suitable for:
