Why RYGWB & 4x Speed Matter
The TK850/TK850i uses a RYGWB timing profile optimized for bright room viewing and HDR. The white segment boosts overall brightness – essential for daytime watching – while the yellow segment improves color saturation and skin tone accuracy. 4x speed offers reliable rainbow reduction without extra motor wear, ideal for long hours of TV, sports, and gaming. Using a different wheel will cause startup failure or permanently wrong colors.
Key Benefits of This Genuine Wheel
- 5‑segment RYGWB design for bright, accurate HDR
- White segment boosts lumen output for daytime viewing
- 4x speed – balanced performance & durability
- Factory‑balanced rotor for quiet, stable operation
- 100% original BenQ part with verifiable label
Signs Your Color Wheel Is Failing
- Projector shuts down seconds after power‑on
- Grinding or high‑pitched whining noise
- Flickering image or rainbow artifacts
- Washed‑out colors, yellow/pink whites, or poor HDR
Replacement takes about 20 minutes if you’re comfortable opening a projector. The mounting holes align perfectly, and the flex cable connects directly. Fresh bearing kills noise, factory balance stops vibration.
Don’t scrap your 4K HDR projector. Replace the one component that actually wears out – and get back to bright, vibrant HDR performance for daytime viewing.
Tip: Verify label 102426843 on your old wheel. Match segment pattern (RYGWB) and diameter. Send a photo if unsure.
