Uncalibrated – Maximum Backlight Level
To compare the G27QC’s performance, we have a collection of 27-inch QHD screens. There's the Cooler Master GM27-CF, ViewSonic Elite XG270QC, Asus ROG Strix XG279Q and Aorus FI27Q. We also included the Gigabyte G32QC, which packs the same specs into a 32-inch QHD panel.
The G27QC offers average brightness with a maximum of just over 318 nits. For gaming, video and apps; this is plenty of light in an indoor environment. Where this monitor excels is in its black levels which are the lowest of the bunch with the backlight turned up all the way. As you can see, Gigabyte manages some impressive contrast numbers for both its screens; over 4000:1 for the G27QC. Only its stablemate, the G32QC boasts more dynamic range. This bodes well for SDR and HDR content alike.
After Calibration to 200 nits
When the playing field is leveled at 200 nits, the G32QC squeaks ahead in the calibrated black level test. But the G27QC is still comfortably darker than the other panels. This is why VA is our tech of choice for gaming monitors. Contrast is king. Even with adjustment, contrast is still nearly 4000:1 in SDR mode. It doesn’t get much better without a FALD backlight.
An ANSI contrast ratio over 3000:1 is a rare achievement for any monitor. Both Gigabyte screens can manage it. Image depth is superb and with so much contrast available, this QHD screen could pass for a 4K resolution monitor. A wide dynamic range goes a long way towards improving perceived resolution. The G27QC looks stunning.
