Design & Build
Video connections comprise VGA, DVI and HDMI ports. Audio is covered by two 1.5-watt speakers, a headphones out and a mini-jack entry (that you'll only really need to input audio when connected via VGA or DVI). With its HDMI port and pair of built-in speakers, you could even use the VX2770Smh-LED as an occasional TV by hooking up a set-top box, a Blu-ray player or a games console.
IPS screen panales ensure wider vertical viewing angles and more even, consistent onscreen colours than TN screen panels. Note, however, that unlike the VP2770-LED and the Asus PB278Q, screen resolution here is 1920 x 1080 pixels not 2560 x 1440 pixels. Pixels are therefore larger in the VX2770Smh-LED and characters are bigger. Ultimately, you only get the same level of onscreen detail as with a 21.5" screen.
Colours & Contrast
Colour reproduction proved an excellent surprise in this monitor. We measured the Delta E at just 2.1 straight out of the box without having changed any settings (we always restore the factory settings as soon as we receive a new monitor to test). Note that Delta E measures colour fidelity—the lower the reading, the more faithful the onscreen colours. Colours can be considered accurate with an average Delta E of 3 or under.
And there's more good news—the excellent colours are accompanied by a high contrast ratio of 1000:1. That's sure to satisfy users looking for first-rate onscreen image quality.
This graph shows the ghosting time, measured in ms, which measures the time it takes this monitor takes to entirely remove the previous frame. The shorter the time, the more fluid moving images will appear.
The input lag is much less of a problem, though. At 13 ms on average, it won't be at all noticeable and won't hold back online multiplayer gamers.
- Accurate colours straight out of the box (Delta E = 2.1)
- Good contrast (1000:1)
- Wide viewing angles
- Relatively low power use (30 watts at 200 cd/m²)
- Not responsive enough for gamers (average ghosting time = 16.5 ms)
- Full HD resolution on a 27" screen (1920 x 1080 pixels)
The ViewSonic VX2770Smh-LED will suit users looking for an accurate onscreen image—so long as they're mainly working with static images. However, the monitor's responsiveness, Full HD resolution and lack of certain hardware features hold it back form a five-star review.
