Display
The Oppo R819 features a 4.7-inch IPS LCD display with a resolution of 720 x 1280 pixels, delivering approximately 312 pixels per inch. The display size and resolution were typical for smartphones in this era, providing vibrant colors and a good level of detail. The screen-to-body ratio stands at around 65.6%, indicating relatively wide bezels compared to today's minimalistic design trends. Nevertheless, the display offers good contrast, with a nominal contrast ratio of 1210:1 and a sunlight contrast ratio of 1.957:1, making it adequately versatile for varying lighting conditions.
