The BenQ LH830ST and BenQ LK830ST share some similarities in projection quality but also have key differences. Both projectors provide 4000 lumens of brightness, ensuring a bright image in various lighting conditions. Both also have a 16.7 ms response time, which should provide smooth performance for most content. Additionally, both projectors support a 60Hz refresh rate and have manual focus controls, though neither includes motorized focus or zoom features.

One of the key differences lies in resolution: the LH830ST outputs at 1080p, while the LK830ST offers a 4K resolution. This means the LK830ST can deliver a higher level of detail compared to the LH830ST. Additionally, the LK830ST has a significantly higher bit depth of 30-bit, while the LH830ST is limited to 10-bit. This may result in a broader color range and smoother gradation on the LK830ST.

Both projectors support HDR10 and HLG, but neither supports Dolby Vision or HDR10+. Furthermore, both models can project images up to a maximum size of 180 inches, with a minimum throw distance of 0.5 meters. In summary, the primary distinctions between the two models are resolution and bit depth, with the LK830ST providing a higher resolution (4K) and greater color depth (30-bit) compared to the LH830ST's 1080p and 10-bit depth.

Connectivity:

In terms of connectivity, the BenQ LH830ST and BenQ LK830ST are nearly identical. Both projectors feature 1 HDMI port, 2 USB ports, and support AirPlay, Bluetooth, Wi-Fi, Chromecast built-in, and Miracast. This allows for convenient wireless streaming and device connectivity across both models.

Both projectors lack VGA and DVI connectors, so users will need to rely on digital connections. Additionally, neither has an RJ45 port for wired networking, but both have an S/PDIF Out port for digital audio output.

Overall, the connectivity options on the LH830ST and LK830ST are very similar, offering a strong set of wireless features and essential ports for flexible usage, without any notable differences between the two models in this category.

Features:
has stereo speakers
has a remote control
has built-in smart TV
has a built-in speaker
audio output power 1 x 2W 1 x 15W
has Dolby Atmos

When it comes to features, the BenQ LH830ST and BenQ LK830ST are quite similar, but there is a key difference in their audio output. Neither model includes stereo speakers, but both have a built-in speaker and a remote control. Both projectors also feature a built-in smart TV, providing additional convenience for users who want to stream content directly from the device.

The main distinction between the two models lies in their audio output power. The LH830ST has a 1 x 2W audio output, while the LK830ST offers a more powerful 1 x 15W audio output. This suggests the LK830ST will produce significantly louder audio from its built-in speaker compared to the LH830ST.

Both projectors do not include Dolby Atmos support, meaning neither offers advanced surround sound technology built into the device. In summary, the primary difference in this group is the audio output, with the LK830ST providing a stronger sound experience thanks to its higher audio output power.

Comparison Summary

This is a specification comparison between the BenQ LH830ST and BenQ LK830ST. Both projectors share a laser light source, 320W operating power consumption, and manual focus. However, the models differ in several key areas: the BenQ LH830ST offers a 1080p resolution and a 10-bit color depth, while the BenQ LK830ST provides a 4K resolution and a 30-bit color depth. The audio output power is 1 x 2W on the LH830ST and 1 x 15W on the LK830ST. Additionally, the dimensions and volume vary slightly between the two models.
