The Optoma UHD35STx builds on one of ProjectorCentral's Best of 2021, the UHD35. Like its standard-throw sibling, the UHD35STx uses a single 0.47-inch DLP chip with pixel shifting technology to create a 4K (3840x2160) resolution. The 240-watt lamp produces 3,600 lumens with a lamp life of up to 15,000 hours in Dynamic lamp mode (life is up to 4,000 hours in Bright, and 10,000 in Eco).
Additional similarities include HDR compatibility, 3D support, and the ability to display 1080p at 240Hz with compatible sources. There's also Enhanced Gaming Mode with a low input lag of 16.9ms (4K/60) down to 4.2ms (1080p/240).
Where the UHD35STx sets itself apart is with its 0.5:1 short throw ratio. The fixed zoom lens can project images with diagonals ranging from 36.43 to 300.53 inches. Projector distance ranges from 15.75 to 129.92 inches from the screen (for proper placement, refer to ProjectorCentral's Optoma UHD35STx projector throw distance calculator). The UHD35STx has an offset of 116% and no lens shift.

The UHD35STx also has fewer connections than the UHD35, getting rid of the VGA and 3.5mm audio in—arguably the two least useful. What's left are two HDMI 2.0 with HDCP 2.2, digital optical out, 3.5mm audio out, a 12V trigger port, RS-232, and a USB-A for service and power. It measures 4.65x12.4x10.63 inches (HWD) and weighs 8.77 pounds.
Available now through authorized Optoma dealers, the projector has a street price of $1,749.
