Uncalibrated – Maximum Backlight Level



The Canvas 27F exceeds its 400-nit claimed brightness in SDR mode by a healthy margin. It’s plenty bright with more than enough light to deliver a vivid picture in any environment. It’s also the brightest monitor of the bunch, which explains the fifth-place finish in the black level test. No matter, it has the broadest dynamic range of the IPS screens at 1,152:1. The VA-based AOC has far deeper black levels, so if contrast is a high priority for you, it’s a great choice.
After Calibration to 200 nits



Calibration doesn’t change the Canvas 27F’s image in any visible way. It slips to fourth in the contrast comparison, but it isn’t too far behind the Monoprice and HyperX displays. Any IPS monitor that can top 1,100:1 is a standout product.
The Canvas 27F stays strong in the ANSI test with a 1,083.7:1 score. That’s also a standout figure, as many IPS screens can’t maintain intra-image contrast over 1,000:1. This is excellent performance.
