We can refresh our memory with the specifications: Projection System – 0.47” single-DMD DLP technology with 8.3 million pixels resolution [Note: TI website still only shows 0.47″ 1080p DLP chipset, 4K chipset measures at least 0.66″] Resolution – VGA (640×480) to 4K UHD (3840 x 2160 native) Brightness (ANSI lumens) – 2200 ANSI Lumens‎ Contrast Ratio (FOFO) – 10,000:1 ‎ Display Color – 30 Bits (1,07 billion color) Light Source – 240W lamp good for 4,000 hours (Normal), 8,000 hours […]

BenQ W1700 4K HDR Video Projector to Sell for Less than $2,000

[Update: The project is now for sale on Amazon for $1,499 shipped] 4K UltraHD TVs have now become affordable, with prices not that far from HD television sets for a given size. But what about 4K projectors? We first find out about development in this space with a demo for Texas Instruments 4K DLP chip in January 2016 at CES. Close to the end of that year, I had another look while writing about a $70,000 Canon 4K projector based on laser technology, and found out the cheapest true 4K projector would sell for around $10,000. I did not pay to much attention to 4K projectors this year, but I’ve been informed that Benq has come up with an affordable 4K HDR projector: W1700 / HT2550 (US) that will start selling for 1,599 Euros including VAT (around $1,885 US) next January. This could well mean $1,600 once it is launched […]
