The Good 120Hz support. BenQ is finally front mounting buttons. Context sensitive OSD. Flexible stand options. Energy frugal. Great warranty.

The Bad Obvious light bleed. Discolouration issues with inversion tests. Touch buttons aren't as responsive as they should be.

The Bottom Line Despite the extra frills, the XL2420T isn't a massive jump, performance wise, above the XL2410T. Still, if seriously smooth gaming performance is your only concern, take a look.

There really is only one reason to buy a TN-based monitor these days: 120Hz. Double the refresh means your games are able to show double the frame-rate of conventional monitors (graphics card willing). Of course, it also means support for Nvidia's 3D glasses, but this is the consolation prize compared to the silky smooth frame rates.

So we have BenQ's XL2420T, the follow up to its lower-numbered XL2410T. The same two serious gentleman are on the box, although there's been a hefty revision to the industrial design.

Stand and ergonomics

BenQ's efforts with its stands have been historically good, and the full range of tilt, swivel, rotate and height adjustment are in play here. There's a hole in the neck for cable management, and a hook at the top for hanging cables or other devices. A handle at the top makes carrying a little less awkward, once you've adjusted the screen's height down as far as it will go. We did find it exceptionally hard to remove all the protective plastic from the stand, as a certain amount seemed to be trapped between two bits of plastic near the top — make sure to have a sharp knife on standby to finish the job.

The bundled "S Switch" remote isn't exactly a game changer, but it could potentially make dealing with the monitor a little quicker. The scroll wheel and back button are used to navigate the OSD, while the bottom three buttons can be set as shortcuts for different monitor functions. By far, the most useful function is to treat it as an input switcher.

Buttons and on-screen display (OSD)

BenQ's finally managed to front-mount its buttons, however, it's also made them capacitive. While this is fine in theory; in practice, you can't hit the buttons too quickly or the monitor simply won't record your press. You have to wait until the OSD shows that you've made an action, then press again, which could lead to frustration as you're making your way through the menus. Every single press will also result in an incredibly annoying beep, something you can thankfully turn off in the OSD.

The buttons are backlit though, and the menu is context sensitive and a great step forward for BenQ.

Context sensitive OSD? Yes, please.

BenQ's got all the regular screen options you'd expect, plus a few unique functions. One of those is what it calls "Black eQualizer", which, for all intents and purposes, appears to be gamma adjustment. The gambit is that gamers can now see more detail in dark areas, and it works rather well in this function.

Scaling options are also impressive. 1:1, full screen and aspect stretch are in there, but you can also emulate monitor sizes, including 17-inch 4:3, 19-inch 4:3 and 16:10, 21.5-inch 16:10 and 23-inch 16:9. We'd advise against using any of the latter modes, as the image ends up looking quite blurry. Stick to 1L1, full screen and aspect.

Other standout features include overscan adjustments for HDMI, and the ability to turn off automatic switching to HDMI if one of the other inputs turns off.

There are also presets you can download and an FPS mode that adjusts the image to try and give you a competitive edge — whether or not you think this makes a difference is personal preference.
