How to remove PWM in SAMSUNG smartphones / My head hurts from a smartphone. My eyes hurt.

Overview

The video presents a settings-based guide for Samsung users who experience eye strain, headaches, dizziness, or discomfort while viewing their phone. The narrator attributes these symptoms to pulse-width modulation (PWM), which they say varies with screen brightness.

Suggested Settings

1. Go to Settings → Display → Screen resolution and select a lower resolution, such as FHD+ (2340 × 1080) or HD+ (1560 × 720), if available. The narrator claims this may reduce or eliminate PWM and lower screen power use. They say most users will notice little difference in sharpness, though colors may appear dimmer.
2. Go to Settings → Display → Screen mode and choose Vivid or Natural. The narrator prefers Vivid and suggests adjusting the additional color settings to taste.
3. Set screen brightness around the middle of the range and turn off Adaptive brightness. The narrator recommends this to avoid brightness changes that they say affect PWM.

Notes

Screen-resolution options vary by Samsung model, and the narrator does not present this method as guaranteed. They ask viewers to report whether they experience PWM-related discomfort and whether the settings help.
