Backlight Picture
Flicker-free
PWM Dimming Frequency
What it is: Flickering pattern at different luminosities.
When it matters: For people sensitive to flickering.
Good value: N/A or high frequencies (> 300Hz). Frequencies that are multiples of 60Hz are better.
Black Frame Insertion (BFI)
What it is: Option to turn screen black between frames.

- Refresh Rate
What it is: How frequently the monitor can refresh and show new frames, and whether it can vary its refresh rate in real-time using technologies like G-SYNC and FreeSync.
When it matters: Mostly for gaming, but does provide a little better motion during normal usage.
Native
What it is: The frequency at which the monitor is capable of displaying images every second.
When it matters: General usage, but better results are most important for gaming.
Good value: >100 Hz
Noticeable difference: 15 Hz
Factory Overclock
What it is: The frequency which the monitor can be boosted to using its internal menu.
When it matters: Gaming and other uses where high frame rate content is consumed.
Good value: >100
Noticeable difference: 15
Variable Refresh Rate
What it is: Feature that allows the monitor to synchronize its refresh rate with the input device's output and reduces stuttering and screen tearing.
When it matters: Almost every use, but is most noticeable in gaming where constant fluctuation in framerate causes distracting artifacts.
G-SYNC Compatible
What it is: We test for FreeSync compatibility with an NVIDIA GTX1060. We check for any excess blur, screen blanking, or excess tearing, and confirm the variable refresh rate range.
When it matters: If you have an NVIDIA graphics card.
Good value: Yes
VRR Maximum
What it is: The maximum frequency covered by the Variable Refresh Rate feature of the monitor.
When it matters: Any time the VRR feature is enabled.
Good value: Matches Refresh rate
Noticeable difference: 10 Hz
VRR Minimum
What it is: The lowest frequency covered by the monitor's Variable Refresh Rate feature.
When it matters: When using the VRR feature of the monitor at lower frame rates.
Good value: 30 Hz
VRR Maximum With OC
What it is: The maximum frequency covered by the Variable Refresh Rate feature when the monitor's overclocking feature is used.
When it matters: When both the overclocking and VRR features are used.
Good value: Matching the overclocked refresh rate.
Noticeable difference: 10 hz

- Inputs
Score components:
- Input Lag
What it is: Delay between input and onscreen reaction.
When it matters: General usage of the mouse and gaming.
Native Resolution
What it is: Lowest input lag possible at the center of the screen, when the monitor is displaying its native resolution at its native refresh rate.
When it matters: General usage and while playing video games.
Good value: < 15 ms
Noticeable difference: 5 ms
Non-Native Res @ Native Refresh
What it is: Lowest input lag possible at the center of the screen, when the monitor is displaying an alternative resolution at its native refresh rate. The non-native resolution tested depends on the native resolution of the monitor, following this pattern unless otherwise specified in the Input Lag text:
Native Resolution Non-Native Resolution Tested
4k UHD QHD
QHD FHD
FHD 1600x900
3440x1440 2560x1080
2560x1080 1920x1080
When it matters: General usage as well as gaming.
Good value: < 15 ms
Noticeable difference: 5 ms
Native Resolution @ 60 Hz
What it is: Lowest input lag possible at the center of the screen, when the monitor is displaying its native resolution at a refresh rate of 60Hz.
When it matters: General usage as well as gaming.
Good value: < 15 ms
Noticeable difference: 5 ms
Variable Refresh Rate
What it is: Lowest input lag possible at the center of the screen, when the monitor is using its Variable Refresh Rate feature at its native resolution.
When it matters: General usage as well as gaming.
Good value: < 15 ms
Noticeable difference: 5 ms
10 bit HDR
What it is: Lowest input lag possible at the center of the screen, when the monitor is displaying an HDR signal at its native resolution and highest refresh rate that supports 10 bit.
When it matters: General usage as well as gaming.
Good value: < 15 ms
Noticeable difference: 5 ms
Black Frame Insertion (BFI)
What it is: Lowest input lag possible at the center of the screen, when BFI is enabled and the monitor is displaying a signal at the highest supported BFI refresh rate.
When it matters: General usage as well as gaming.
Good value: < 15 ms
Noticeable difference: 5 ms
- Resolution and Size
What it is: The number of pixels the monitor can display, and the surface area of its screen.
