The Viewsonic VG2437mc-LED is a hybrid of sorts; it's positioned as a business monitor with a built-in teleconferencing solution, but it would do just fine serving as a home monitor too. For just under £200 you get lots of bells and whistles with this 24in model, including a webcam, an ergonomic stand, USB ports, and a DisplayPort input. It doesn't have an HDMI port, but it does have two digital inputs, and it delivers a very good greyscale performance for a TN panel. Colour quality is also quite good and the panel doesn't use much power. However, its viewing angle performance holds it back.
Design and features
The VG2437 uses a 24in TN (twisted nematic) panel with a 1,920 x 1,080 resolution. It's housed in a matte black cabinet with thin (10mm) top and side bezels and a wider (25mm) bottom bezel. A white Viewsonic logo graces the bottom bezel, and there are five clearly labelled buttons, including the power switch which is off to the right. Above the display, embedded in the bezel, is a 2-megpixel webcam along with an echo-cancelling microphone. A pair of 2 Watt speakers rounds out the videoconferencing solution.
The 3.75kg cabinet is supported by an ergonomic stand that offers every adjustment you'll need for comfortable viewing. A telescopic mounting arm provides 5.3in of height adjustability, and the hinge assembly lets you tilt the panel forward 5 degrees and backward 20 degrees. There's a Lazy Susan on the base that offers 360 degrees of swivel and you can pivot the panel for portrait mode viewing. However, the picture does not automatically change orientation when you rotate the screen.
All of the VG2437's I/O ports are located at the rear of the cabinet. You don't get an HDMI port on this model; instead the folks at Viewsonic decided to go with the more business-centric DisplayPort input. If you must connect the monitor to a device with an HDMI output, a simple DVI-HDMI adapter will do the trick. You also get DVI and VGA (analogue) video inputs, an upstream USB port, and two downstream USB 2.0 ports. Audio ports include a headphone jack, a microphone input, and a microphone output.
Picture settings include contrast, brightness, colour temperature, ECO mode, and dynamic contrast. If you're using an analogue signal you can adjust horizontal position and size, sharpness, and aspect ratio. There's also an input select hot key and speaker volume controls.
The VG2437 comes with a three year warranty covering parts, labour, and backlighting. Included in the box are VGA, DVI, USB, and audio cables as well as a resource CD and a Quick Start Guide.
The VG2437 was able to display each shade of grey from the DisplayMate 64-step Greyscale test. There was only a slight trace of compression at the high end of the scale that made the two lightest shades of grey appear white, but the overall greyscale performance was impressive for a TN panel. Colours appeared vibrant and well saturated, and small text was sharp and easy to read.
Viewing angles were less impressive. Colour shifting was significant when viewed from a side angle and the picture darkened when viewed from the top and bottom. This won't be an issue if you're positioned directly in front of the display, but if you rotate the panel to portrait mode and move your head to either side the picture deteriorates and is particularly dark when viewed from the left side. This is a common characteristic of TN panel technology, which is one reason why IPS panels like the one used in the similarly priced NEC MultiSync EA232WMi are becoming so popular.
The VG2437 may be designed for business use but it is well suited for playtime, too. The panel's 5ms (black to white) pixel response had no trouble handling fast motion while playing a few rounds of Far Cry 2 on the PC, and the BBC's Planet Earth looked superb at 1080p on Blu-ray.
The VG2437 is a power miser; it used just 19 Watts of power while running in Standard mode. Switching to the ECO Optimise mode lowered power consumption to 16 Watts without becoming too dim, and Conserve mode used 12 Watts. Conserve mode is significantly dimmer than Standard mode, but the picture is still bright enough for most lighting environments. This highly impressive level of energy efficiency rivals that of the Lenovo LS2421P Wide (which also sips 16 Watts).
For businesses seeking a full featured monitor that is budget-friendly and inexpensive to operate, the Viewsonic VG2437mc-LED is a good bet. It offers good colour and greyscale performance and lots of features, including an ergonomic stand and a built-in webcam. Its motion handling prowess makes it ideal for after-hours use as well. That said, its subpar viewing angle performance prevents it from displacing the NEC Multisync EA232WMi as our current favourite when it comes to mid-sized business monitors.
