The Epson EH-QB1000 projector is based on a simple blue laser light source. A phosphor treatment creates the red and green components to obtain an [abc]RGB[/abc] source. The main advantages of a laser light source, in addition to an extremely short on/off time, concern its lifespan (20,000 h), and its brightness, 3,300 lumens here.
Epson EH-QB1000, Pixel Shift process££££
The Epson EH-QB1000 is of course capable of displaying an [abc]Ultra HD[/abc] [abc]4K[/abc] image, still based on the wobbling principle called Pixel Shift at work on the vast majority of UHD video projectors, consisting of the extremely rapid display of four Full HD images offset diagonally and from bottom to top to create 8,294,400 pixels, the total of a native 4K Ultra HD image. This technology improves contours, eliminates aliasing and increases contrast in highly textured image portions. Ultimately, the precision and sharpness are far superior to those of a Full HD image. Especially with the use of a glass lens composed of fifteen elements arranged in various groups to minimize chromatic aberrations and artifacts.
Epson EH-QB1000, main specifications££££
In addition to a bright laser source, 3,300 lumens we repeat, the contrast ratio of the Epson EH-QB1000 is remarkable, 5,000,000:1 dynamic, 5,000:1 native, thanks to the exclusive UltraBlack technology. For the rest, [abc]LCD[/abc] 0.74'' C2 Fine panels, manual vertical/horizontal keystone correction ±30°, x2.1 zoom, motorized vertical/horizontal Lens Shift ±47.1%/±96.3% and automatic focus are all part of it. The fixed 1.35-2.84:1 projection ratio allows for an image size ranging from 50" (127 cm) to 300" (762 cm). Finally, the [abc]HDR10[/abc]/[abc]HDR10+[/abc] and [abc]HDR HLG[/abc] formats, in addition to 91% coverage of the DCI-P3 gamut and 125% of Rec.709. But the most interesting feature is the presence of the new exclusive 32-bit QZX processor, the latter allowing the integration of a DTM (Dynamic Tone Mapping) process for significantly improved image quality compared to basic Tone Mapping processing. Precision, the Epson EH-QB1000 is [abc]ISF[/abc] certified and the operating noise displays 32 dB in Normal mode, 22 dB in Eco mode.
Another clear evolution linked to the QZX chip, the [abc]Deinterlacing[/abc] and Image Enhancement sections now offer an Upscaling of excellent quality. The same goes for the Frame Interpolation function (adjustable on three levels) which provides truly superb motion compensation. Namely, in the absence of speakers the audio capabilities of the Epson EH-QB1000 are zero and 3D compatibility is not available.
Epson EH-QB1000, connectivity££££
The connectivity of the Epson EH-QB1000 (see photo above) has two [abc]HDMI[/abc] 2.1 40 Gbps inputs certified [abc]HDCP[/abc] 2.3 and [abc]ALLM[/abc] ([abc]ARC[/abc] management on one of them and 4K), two [abc]USB[/abc] Host 2.0 ports, a mini USB-B port, an [abc]RS-232[/abc]C socket, an [abc]Ethernet[/abc] port and a 12V [abc]Trigger[/abc] output. Epson specifies that the Input Lag is low, less than 20 ms in the presence of a [abc]2 160p[/abc]/60 signal, less than 10 ms with a 4K/120 hertz signal.
Availability, in white or black, immediate. Indicative price: 5,499 euros.
