Design and Build
This 27" monitor has a quite striking, quite imposing design. Its triangular stand takes up a fair bit of room, so you may need to make some space on your desk (in measures approximately 55 cm x 40 cm).
Although this monitor's design may lack a little finesse—as is often the way with professional monitors—the hardware is excellent. For starters, connections comprise VGA, DVI (Dual-Link), DisplayPort and HDMI (1.4) ports.
Beware, though, as not all of the video connections are able to handle the screen's native resolution (2560 x 1440 pixels). There are no such problems with DVI and DisplayPort, but if you're connecting via HDMI or VGA, you'll be limited to Full HD (1920 x 1080 pixels) and 2048 x 1142 pixels. With its native resolution, the VP2770-LED can display 77% more info onscreen than a Full HD display.
The Viewsonic VP2770-LED uses a PLS screen panel (that's Samsung's version of IPS) which makes for wide viewing angles and consistent display quality over the screen.
Colours and Contrast
The good news for photo editors, or other users looking for accurate onscreen colours, is that the VP2770-LED is pre-calibrated in the production factory before being dispatched to resellers. You'll therefore find a slip of paper in the box assuring you that your new VP2770-LED has an average Delta E of under 3 and that no individual colour has a Delta E of over 5. Note that Delta E measures colour fidelity, with anything under 3 considered accurate.
In our own lab tests, we measured the average Delta E at 2.2 with the VP2770-LED's factory settings—no complaints there. With the default settings, some may find the onscreen image too bright (the white is at 296 cd/m²). This can be remedied by switching to sRGB mode, which reduces brightness significantly with no negative impact on colour fidelity.
We measured the contrast at 870:1, which remained stable across all screen brightness settings. Admittedly, we were hoping to see slightly higher contrast, but it's still above average compared with other monitors we've reviewed (850:1).
Responsiveness—or rather the lack of responsiveness—is no doubt the main drawback of this VP2770-LED monitor. Viewsonic announced a response time of 12 ms, but we measured an average of around 19 ms. That won't be a problem for retouching photos or any other activity involving static images. However, the onscreen image won't look 100% clear and sharp when people or objects are moving around quickly (video games, sweeping scenes in films, etc.).
- Relatively low power use (30 watts at 200 cd/m²)
- Very accurate colours straight out of the box (Delta E = 2.2)
- Hardware features
- Wide viewing angles
- Not responsive enough for gaming (19 ms average ghosting time)
While the response time of the Viewsonic VP2770-LED clearly isn't fast enough for gamers, this monitor still has enough excellent features to earn a five-star review. Viewing angles are wide, power use is relatively low, colours are accurate with the factory settings, contrast is above average and there's a good range of hardware features.
