PWM dims the backlight, and minor flickering is evident at lower brightness. This is a panel that is best at high brightness. If you suffer from PWM flicker, then look for a non-IPS screen.

Response times

Claimed 8ms GTG. While this is a figure that gamers want, office use is closer to 15ms in ‘Normal’ settings. In most cases, the adaptive free sync effectiveness is really dependent on the video card.

Picture mode SDR: Vivid, HDR effect, Reader, Cinema, sRGB, DCI-P3, Games (FPS, RTS,), EBU, REC.709, SMPTE-C, Colourblind (R/G compensation), Calibrate 1 and 2. We found Vivid had the most pleasing saturated colours but are less accurate. Professionals will select sRGB (web colours) or DCI-P3 (movie colours).

Picture Mode HDR (content metadata dictates colours): Vivid, Standard, Cinema and Game (FPS/RTS). HDR mode does depend on content, video card and Windows/Mac support.

Colour mode: Gamma, Colour temperature, RGB, Six Colour (R,G,B,C,Y,M – tone and saturation). Set this to 6500K.

Super Resolution+: High, Middle, Low and Off. We found ‘off’ is the best setting, as higher levels tend to induce motion blur.

Black Level: Only works on HDMI signals so not applicable to Thunderbolt 3 signals as tested

Uniformity: Works in Custom, sRGB and Adobe RGB and ensures uniformity of colours but reduces brightness. Leave it off.

Games: Response time, FreeSync, Black Stabiliser (like a faux HDR)

Modes: PIP and PBP

Software (URL here).

On-screen control requires Windows or Mac OnScreen Control Software. It is effective and in Windows, mouse driven.

Dual control (PBP or PIP) may require Dual Control software for Windows and Mac.

True Colour Pro for calibration is for Windows and Mac and requires a compatible hardware sensor like a CalMAN or Spyder. You can also use most third-party calibration software.
