ViewSonic VA2456A-MHD 24"

Manufacturer: ViewSonic

The ViewSonic VA2456A-MHD is a 24-inch class standard monitor built around an IPS panel with LED backlighting, offering wide 178-degree viewing angles both horizontally and vertically. Its matte, anti-glare surface helps reduce reflections in typical office or home environments, while the stand supports tilt, swivel, and portrait mode rotation, along with VESA mount compatibility for added placement flexibility.

Running at 120Hz with a 1ms response time, the display outputs a 1920x1080 resolution at 92 ppi and delivers a contrast ratio of 1500:1 alongside a typical brightness of 250 nits. Color performance is handled by an 8-bit panel covering 99% of the sRGB color space with 16.7 million colors and color calibration support. Connectivity includes one HDMI 1.4 port, one DisplayPort output, a VGA connector, and a 3.5mm audio jack, complemented by built-in stereo speakers rated at 2x2W. Power draw is rated at 18W during operation and 0.3W in standby.

Pros
  • The IPS panel provides wide 178-degree viewing angles both horizontally and vertically, ensuring consistent image quality from various seating positions
  • The stand supports tilt, swivel, and portrait mode rotation, along with VESA mount compatibility, offering flexible ergonomic and placement options
  • 99% sRGB coverage combined with color calibration support makes color output reliable and adjustable for color-sensitive work
  • At 120Hz refresh rate with a 1ms response time, the display handles fast-moving content with minimal blur or delay
  • Built-in stereo speakers rated at 2x2W remove the immediate need for a separate audio device in basic use scenarios
  • The matte panel with anti-glare coating reduces reflections in environments with ambient lighting
Cons
  • No adaptive synchronization support, which can result in screen tearing during fast-paced content without additional software solutions
  • Pixel density of 92 ppi at 1920x1080 on a 23.8-inch screen produces a relatively low sharpness level for detail-focused tasks
  • No USB ports of any kind, including USB Type-C, limiting connectivity options for peripherals and devices
  • The single HDMI port is version 1.4 only, which restricts bandwidth compared to newer HDMI standards
  • No Picture-in-Picture support, preventing simultaneous display of multiple input sources on screen
Who is this for?

This monitor is well suited to everyday office users and home setups where reliable color accuracy matters, thanks to its 99% sRGB coverage and color calibration support. The ergonomic stand with tilt, swivel, and portrait mode rotation makes it a practical choice for users who need flexible positioning throughout the day. Its 120Hz refresh rate and 1ms response time also make it a reasonable option for casual gamers or users who work with fast-moving content and want a smoother visual experience without investing in a specialized display.

Who is this NOT for?

Users who require sharp, detailed visuals for tasks like photo editing at close range or high-resolution design work may find the 92 ppi pixel density insufficient for their needs. Competitive gamers who rely on adaptive synchronization technologies to eliminate screen tearing will be limited by the absence of any sync support. Additionally, users with multiple peripherals or devices to connect will likely find the connectivity options restrictive, given that the monitor offers no USB ports and only a single HDMI 1.4 input alongside DisplayPort and VGA.
