Uncalibrated – Maximum Backlight Level
In addition to the Odyssey G7, we have two other 32-inch VA displays in our database: the Gigabyte G32QC and Dell S3220DGF. Samsung also brings speedy operation with its 27-Inch CRG5 240 Hz monitor. We also threw in our two most recently reviewed speed demons, the 360 Hz Asus ROG Swift PG259QN and 280 Hz Asus TUF VG259QM.
Samsung rates the 32” Odyssey G7 as hitting 320 nits brightness for SDR signals, but our sample was comfortably over 380 nits. That much light from such a large screen is enough to illuminate a small room. Bigger screens don’t need to exceed 400 nits in SDR mode to provide enough output for a good picture.
The four VA panels have less than half the black level luminance of the two IPS monitors from Asus. The C32G75T has the highest black level of that four, but it’s still lower than any IPS or TN display can muster. Resulting contrast is a little low for a VA monitor, 2220.8:1. That figure rises to around 4,000:1 if you turn the local dimming on for SDR signals. There is no downside to this option, so we recommend using it.
After Calibration to 200 nits
Our calibrated black level and contrast measurements are taken with local dimming turned off to show the panel’s native response. The top three VA monitors still beat the Odyssey G7 by a smidge, but the Samsung still delivers a deep and dimensional image with saturated color and true blacks.
ANSI contrast is a respectable 1,921.4:1. Although other VA monitors can do better, this is not a deal-breaker. The 32” Odyssey G7 has many other virtues which make this a non-issue.
