BenQ TK705i VS Optoma Photon Life PK32

The BenQ TK705i and Optoma Photon Life PK32 differ in several key aspects when it comes to their general specs. Starting with the light source, the TK705i features a laser light source, while the PK32 does not. Both projectors have the same lamp life in eco mode, rated at 30,000 hours. However, the TK705i has a higher operating power consumption at 250W, compared to the PK32's 163W.

In terms of physical size, the TK705i is slightly larger, measuring 230 mm in width, 170 mm in height, and 250 mm in thickness, with a total volume of 9775 cm³. The PK32, on the other hand, is more compact, with a width of 240 mm, height of 130 mm, and thickness of 220 mm, giving it a smaller volume of 6864 cm³.

When it comes to weight, the TK705i is considerably heavier at 3800 g, compared to the PK32's 2200 g. Additionally, the TK705i offers a dedicated smartphone app, while the PK32 lacks this feature.

The BenQ TK705i and Optoma Photon Life PK32 share the same 4K output resolution but differ in several other key projection features. The TK705i has a slightly slower response time at 5 ms, while the PK32 is faster at 4.6 ms. Both projectors offer motorized focus, but neither includes motorized zoom, and neither has manual focus options.

When it comes to the maximum projection size, the TK705i supports a larger image of 160 inches, compared to the PK32's 150 inches. The TK705i also supports HDR10+ and boasts a higher 10-bit color depth, whereas the PK32 only supports HDR10 and has an 8-bit color depth.

For minimum throw distance, the TK705i has a shorter requirement of 1.4 m, while the PK32 needs a longer 1.9 m. Additionally, the TK705i refreshes at 60Hz, while the PK32 has a much higher refresh rate of 240Hz. Both projectors support HDR10 and HLG, though the PK32 lacks HDR10+ support.

When comparing connectivity features between the BenQ TK705i and the Optoma Photon Life PK32, both projectors offer two HDMI ports and two USB ports. However, the TK705i stands out with several additional connectivity features. It includes AirPlay, Bluetooth, Chromecast built-in, and an S/PDIF Out port, none of which are available on the PK32.

The PK32, in contrast, lacks AirPlay, Bluetooth, Chromecast, and the S/PDIF Out port. Neither projector supports Wi-Fi or has VGA or DVI connectors. Additionally, neither has an RJ45 port or supports Miracast.

In summary, while both projectors offer essential connectivity like HDMI and USB, the TK705i provides more advanced wireless and audio options compared to the PK32, which is more basic in this regard.

The BenQ TK705i and Optoma Photon Life PK32 both feature stereo speakers and a built-in speaker, but they differ in a few key areas. The TK705i offers stronger audio output, with 2 x 8W, compared to the PK32's 2 x 5W. Additionally, the TK705i includes a built-in smart TV feature, which the PK32 lacks.

Both projectors come with a remote control, and neither has vertical or horizontal lens shift. They also both have a socket for a 3.5 mm audio jack, but neither offers an external memory slot or supports voice commands.

In summary, while both projectors offer similar audio features and remote control capabilities, the TK705i provides an enhanced audio output and includes smart TV functionality, which the PK32 does not.
