Optoma Photon Life PK31 4K projector available for around $599

Optoma‘s Photon Life PK31 is a compact 4K UHD home projector that can cast an image up to 150 inches and is currently selling for around $599 in the US. The RGB LED model is aimed at movie nights, streaming, and low-lag gaming without the bulk of a traditional living-room projector. Here is a look at the confirmed specifications and where you can buy it.

Optoma Photon Life PK31 specifications and features

The Photon Life PK31 uses Texas Instruments DLP technology to deliver a 4K UHD image at 3840 x 2160. Optoma rates brightness at 900 ISO lumens, or 1,600 HK lumens, with a 200,000:1 contrast ratio and support for HDR10 and HLG.

Color coverage is listed at 95 percent of DCI-P3. The light source is an RGB LED system with a life of up to 30,000 hours in eco mode, so there is no lamp to replace during normal use.

Screen sizes run from 60 to 150 inches. The throw ratio is 1.5 to 1.65, which works out to roughly 2.1 to 5.2 meters of distance for that full size range, and a manual 1.1x optical zoom helps fine-tune the picture.

Gamers get Optoma’s Game Mode input-lag figures of 4.6ms at 1080p and 240Hz, 8ms at 1080p and 120Hz, and 16ms at 4K and 60Hz. Manual vertical and horizontal keystone correction covers up to 40 degrees in each direction for uneven placement.

Connectivity is kept simple with one HDMI 2.0 port, a USB-A output rated at 5V/2A for powering a streaming stick, and a 3.5mm audio jack. A single 5W speaker handles onboard sound, while noise is rated as low as 26dB in eco mode and up to 32dB in bright mode.

The chassis measures 238 x 215 x 117.7mm without the feet, or 238 x 215 x 130mm with them, and net weight is about 2.2kg. That compact footprint makes it easier to move between rooms than Optoma’s larger home models, including the Photon Beam PK52 we reviewed earlier.

There is no built-in smart OS, Wi-Fi, or Bluetooth on the official spec sheet, so a Fire TV Stick, Roku, or similar HDMI dongle is the usual way to stream. The USB-A port can supply power to that stick, letting the whole setup run from a single wall outlet.

Would a $599 4K projector with a 150-inch ceiling change your living-room setup, or are you still waiting for a brighter short-throw option?
