Picking a 4K Projector for 150" Cinema

[Symbian41]

Hi everyone,

I’m building a dedicated movie room in India (14x16ft) and need advice on choosing a "Cinema First" 4K projector. I’ve used AI to create a summary of the current market prices and specs, but I need real-world feedback from the videophiles here.

My Setup:

• Room Size: 14ft x 16ft.
• Usable wall size for screen 11ft 2 inch
• Throw Distance: 16 feet (Back wall mounted).
• Screen: 150-inch pull down manual.
• Usage: 100% Movies (NO gaming).
• Source: Playing 50GB–80GB 4K MKV Remux files via VU QLED 65 inch TV
• TV - 65QMP (Masterpiece Glo Series)
• Audio: Yamaha RX-V3072 AV Receiver (HDMI Passthrough).

My Specific Questions:

1. Lens Quality at 16ft: With 80GB MKV files, I don't want the projector glass to be the bottleneck. At a 16ft throw, which of these maintains the best focus across a 150" area?
2. Dust & Heat (India): Are the Laser units (BenQ/ViewSonic) truly sealed against dust? In my city, dust is a major issue for internal optics.
3. AVR Handshake: Any known issues connecting these newer 4K models through an older (but high-end) Yamaha RX-V3072 for 4K/HDR signals?
4. Alternatives: Are there any other brands in India (like Sony, Samsung, or LG) worth considering under 1.5L for a purely cinematic experience?

I'm leaning towards the BenQ TK710 because of the laser longevity and sharpness, but would love to hear from anyone with a similar 150-inch setup.
Thanks for the help!
