LG Smart Monitor 32SR73U 32"

Manufacturer: LG

The LG Smart Monitor 32SR73U is a 32-inch display that blends monitor and smart TV functionality into a single unit. Running on a VA LCD panel with LED backlighting, it features built-in smart TV capabilities along with Wi-Fi and AirPlay support, making it suited for both work and media consumption without requiring an external streaming device. It also includes a remote control and stereo speakers, rounding out its standalone usability.

On the technical side, the 32SR73U delivers a 3840 x 2160 resolution across a 31.5-inch panel, resulting in a pixel density of 139 ppi. The VA panel offers a 3000:1 contrast ratio, 250 nits of typical brightness, and wide 178-degree viewing angles both horizontally and vertically. Connectivity options include two HDMI 2.0 ports, a USB Type-C port, and three additional USB ports, while the matte, anti-glare coating helps manage reflections in varied lighting conditions. The display supports VESA mounting and portrait mode orientation, and its standby power draw sits at just 0.5W.

Pros
  • 4K UHD resolution on a 31.5-inch panel results in a pixel density of 139 ppi, producing a sharp and detailed image
  • Built-in smart TV functionality combined with Wi-Fi and AirPlay support allows wireless content streaming without any external device
  • Includes stereo speakers and a remote control, enabling use as a fully self-contained screen without additional accessories
  • The matte, anti-glare panel helps maintain visibility in environments with ambient light sources
  • Supports portrait mode and VESA mounting, offering flexibility in how the display is physically set up
  • Color calibration support and a 3000:1 contrast ratio give users meaningful control over color accuracy
Cons
  • The 60Hz refresh rate and lack of adaptive synchronization make this display a limited option for fast-paced or motion-heavy content
  • No 3.5 mm audio jack means headphones or external audio devices cannot be connected directly to the monitor
  • Ethernet is not supported, so wired network connectivity is unavailable
  • No DisplayPort output of any kind restricts wired video input options to HDMI and USB-C only
  • At 250 nits of typical brightness, the display may struggle in very bright environments
  • Picture-in-Picture is not supported, limiting multitasking across multiple simultaneous inputs
Who is this for?

This monitor works well for users who want a display that doubles as a smart entertainment hub, since the built-in smart TV platform, Wi-Fi, AirPlay, stereo speakers, and remote control allow it to function independently of a computer or streaming device. The 4K resolution at 139 ppi makes it a solid fit for content consumption, photo review, and detail-oriented office work where image sharpness matters. Its support for portrait mode and VESA mounting also makes it a practical choice for users who need flexible installation options, such as wall-mounting in a home office or media room setup.

Who is this NOT for?

Users who engage in competitive gaming or fast-motion content will find this monitor limiting, as the 60Hz refresh rate and 5 ms response time — combined with the complete absence of adaptive synchronization — are not suited to that type of use. Those who rely on multi-source input flexibility may also find the connectivity restrictive, given the lack of DisplayPort outputs, no 3.5 mm audio jack, and no Ethernet port. Additionally, users working in very bright rooms may find the 250-nit brightness insufficient to maintain a comfortable viewing experience under strong ambient lighting conditions.
