[SPECS]1920×1080 resolution, 144Hz refresh rate, 1ms GtG response, TN-panel, anti-glare matte display, 1000:1 contrast ration, 450cd/m2 brightness, 1x DP 1.2, 1x HDMI 1.4, 1x DVI-D[BODY]
If you’ve ever had the pleasure of witnessing the silky-smooth output of a graphics card and monitor working in unison to display 144 frames per second, you never want to play games any other way. Unfortunately, most monitors capable of such a feat are also expensive. That changes with Acer’s new KG251QF.
This 24.5-inch monitor brings that 144Hz goodness we all want, at a low $299 price point. The KG251QF uses a 1920 x 1080 Full HD, matte anti-glare coated, twisted nematic (TN) panel. Thanks to Acer’s choice of TN technology, the KG251QF is not just capable of fast refresh rates but can achieve a miniscule 1ms grey-to-grey response time. An ideal combo for first person shooters.
The downside of that TN panel, fast response time and refresh rate is relatively poor image quality. For most gamers, this isn’t a huge concern, but for those who do any sort of photo editing, the KG251QF should be avoided. A very sparse 72% coverage of the already low-end NTSC colour gamut, plus a 6-bit panel with frame rate control (FRC) means you miss out on seeing all the beautiful colours possible on other displays.
Viewing angles on the KG251QF are a weak too, with the usual 170-degree horizontal, but a poor 160-degree vertical angle. Unless your head is dead centre on the monitor, image quality suffers. But this is a 24.5-inch gaming monitor, not a TV and 99% of the time you’re going to be sitting dead centre anyways, so it’s not that big of a deal.
AMD’s FreeSync technology is built-in to the KG251QF making sure your graphic card’s frame rates are kept in sync with the display’s. No Nvidia G-Sync here, which keeps the price down. A FreeSync monitor paired with a FreeSync graphics card prevents annoying graphics tears, glitches and smudges by allowing the graphics card to dynamically control the monitors refresh rate, so they’re always perfectly aligned.
The KG251QF includes a blue-light filter to protect your eyes from prolonged computer use. LED backlit monitors radiate a large amount of blue-violet light that is unnatural in such concentration and can damage vision. According to many studies, this blue-violet part of the light spectrum can actually burn our eyes slowly over time. Considering how often most of us sit in front of a screen these days, being bombarded with blue-violet light all that time is not ideal!
Blue-violet light also disrupts normal sleeping patterns as it’s typically found in the morning, making going to sleep difficult to sleep for some people after using their computer. By turning blue-light filter on, the KG251QF lowers the amount of blue-violet light without impacting image quality.
Ports on the KG251QF are basic: 1x DisplayPort 1.2, 1x HDMI 1.4, 1x DVI-D Dual Link and a 3.5mm audio output. No USB hubs or multiple inputs for picture-in-picture action. The built-in speakers suck, but that’s par for the course when it comes to speakers inside monitors.
The physical design of the KG251QF is simple. No flashing lights or huge decals, just a plain black case with a thin bezel. The included stand is a bit cheap, with no height adjustment, just tilt. Luckily there’s a VESA mount, which combined with the thin bezel, light weight (3.7kg) and low price, makes the KG251QF a great candidate for a triple monitor setup.
It’s clear that Acer made some compromises in the colour gamut department on the KG251QF to achieve such a fast monitor at a low price point, but for most gamers it’s totally worth it. The KG251QF is a clean looking monitor, with no obnoxious bling and a thin bezel that gets out of the way to let the image on the screen do the talking. With a 144Hz refresh rate, 1ms response time, AMD FreeSync and low $299 price, it’s great value for the no-frills gamer.
