The ViewSonic VX2739wm is a 27-inch, 1920x1080 TN-based screen. Coated in gloss black, the fascia is plain save for a single power button in the middle, which glows white below the ViewSonic logo.
This is not the first time ViewSonic has outed a monster monitor, with the 26-inch VX2640w providing a full 1080p resolution before it. It is, however, the first 27-inch screen we've seen with the lower 1080p resolution — competitors like the Dell UltraSharp U2711 or even come in at a much more impressive 2560x1440, and both are based on IPS technology, which gives them superior colours and viewing angles. Even Dell's older UltraSharp 2709w offered the 16:10 resolution of 1920x1200.
This isn't necessarily a bad thing — for one, the smaller resolution means a significantly larger dot pitch. This means elements will appear larger, and text should be easier to read. While the DPI scaling in Windows 7 makes these sorts of troubles a thing of the past, those who are running on other operating systems or whose eyes aren't as good as they used to be will appreciate the extra size afforded to them by ViewSonic's screen.

Despite the screen size, ViewSonic has bafflingly opted to give very little adjustability in the stand at all, only including tilt — a trademark generally found in cheap 22-inch monitors.

It's rare to find good speakers in a monitor, and ViewSonic continues the fine tradition of providing incredibly poor audio. While it has better mid-range than some, it sacrifices high-end clarity and completely lacks bass. The top firing speakers also sound distant, and although a respectable volume can be achieved, it distorts easily. As usual, we recommend keeping to dedicated speakers, or making use of the headphone jack on the side to bypass the monitor speakers completely.
Side buttons! Only secondary in annoyance to underside buttons, ViewSonic's OSD is all the more annoying as you adjust and attempt to reprogram your muscle memory on the fly. The indented labels aren't particularly clear against the black gloss either, making it a difficult task to adjust settings in low light.
ViewSonic persists with annoyingly putting buttons on the side. It's not exactly conducive to adjusting in the dark either, but with only four buttons muscle memory will eventually kick in. (Credit: CBS Interactive)
Thankfully, the VX2739wm has received ViewSonic's newer OSD, which sports a cleaner look and it's easy to find your way around, button mashing aside. Don't expect anything fancy here though in terms of adjustments — just like the stand, you're given basic options only. Vexingly, scaling options are limited too, only offering 4:3 and fill.

There's a large annoyance introduced here: as far as we can tell, there's no way to switch to a predetermined input, the monitor simply scans what's available, and switches to the next in queue.
This behaviour annoyingly continues when one input is removed. Say you've just shut down your PC, but happen to have your PS3 hooked up to the HDMI port. You're ready to walk away from the monitor for the day, but because it auto-switches, it changes to the HDMI port and doesn't turn off. It's a huge waste of power, and we're not sure what ViewSonic was thinking here.

By default, the image is way too sharp — however, the only time sharpness can be adjusted is when the screen is running lower than native resolution. Most monitors fail between one and four pixel walk tests, so in this instance we're not too concerned; the higher level of failures simply being representative of the price band ViewSonic is playing in.
Measured against a Samsung SyncMaster 975p CRT, and using a Canon 40D set to a shutter speed of 1/320, an average of over 60 photographs were taken using StoppUhr. Being a TN panel the ViewSonic did well, clocking in at 17.1ms — approximately one frame of input lag.
ΔE is the measurement of how far a measured colour deviates from its expected value, allowing us to determine the colour accuracy of a monitor. While a ΔE value of 1 is considered perceivable, as long as it's less than 3 the shift shouldn't be too obvious. HCFR was used to determine ΔE for the monitor.

Not the worst we've seen, but the greys as usual could be better. (Screenshot by CBS Interactive)
