240 Hz FHD monitors are THE performance bargain, so I’ve rounded up a group of them from my test database to compare the Canvas 27F’s results. Included are the HyperX Armada 25, Pixio PX259P, Viewsonic XG2431, Monoprice 40778 and AOC C32G2ZE.

The first thing you’ll notice is that the Pixio can run at 280 Hz, but there is no apparent advantage here. It refreshes at 4ms like most 240 Hz screens and ties the Canvas 27F for first place in the lag test with 20 ms. Only a 360 Hz screen can respond quicker and costs about twice as much as the monitors here. For most gamers, myself included, a spread of 20 to 25 ms is small. The gaming experience will be roughly the same when playing on any of these panels. A highly skilled player will undoubtedly prefer the Canvas 27F for competition. It is completely qualified for premium eSports play.
Viewing Angles
The Canvas 27F is an excellent example of what IPS viewing angles can be. There is almost no reduction in brightness at 45 degrees off-axis and the color shift is barely visible as a blue tint. Gamma remains the same, meaning shadow and highlight detail stays sharp. The top view is slightly washed out and green but looks better than many similar IPS panels I’ve photographed.
Screen Uniformity

I consider any result under 10% to be visually perfect in the black field uniformity test. The Canvas 27F posted one of the best results I’ve seen, with just a 4.07% deviation from the center zone. No anomalies are visible in any test pattern, color or otherwise, even in a completely dark room. This is excellent performance, especially for such an inexpensive monitor.
