Xiaomi 15 Pro Display Overview
The Xiaomi 15 Pro features a 6.73-inch AMOLED display that delivers a resolution of 3200 x 1440 pixels (QHD+), with a pixel density of approximately 521 to 522 pixels per inch. This display is built on an advanced Xiaomi-custom M9 AMOLED panel known for its superior brightness and efficiency. It supports a 120Hz refresh rate with LTPO adaptive technology, allowing the refresh rate to dynamically scale between 1Hz and 120Hz depending on the content displayed, which helps conserve energy. The screen also supports HDR10+ and Dolby Vision for enhanced contrast and color accuracy.Brightness is a key highlight, with the Xiaomi 15 Pro reaching a peak brightness of up to 3200 nits, specifically over about 25% of the screen area. This ultra-high peak brightness ensures good visibility even under bright sunlight. The display reproduces up to 68 billion colors, providing exceptionally vibrant visuals, and includes TÃV Rheinland certifications for low blue light, flicker-free display, and circadian rhythm friendliness, contributing to reduced eye strain.
The Xiaomi 15 Pro display also integrates Dolby Vision for enhanced HDR content viewing, Dolby Atmos support for audio, and is protected by a 2024 generation shatterproof glass. The design incorporates a 20:9 aspect ratio screen with a high screen-to-body ratio of approximately 91.5%, allowing for an immersive edge-to-edge viewing experience. It also features an optical in-screen fingerprint sensor embedded beneath the display.
Samsung Galaxy S24 Ultra Display Overview
The Samsung Galaxy S24 Ultra includes a slightly larger 6.8-inch Dynamic AMOLED 2X display with a resolution of 3200 x 1440 pixels (WQHD+), which yields a pixel density around 515 to 518 pixels per inch. This panel supports an adaptive 120Hz refresh rate with LTPO technology similar to the Xiaomi 15 Pro, enabling smooth scrolling and animations while optimizing battery consumption by adjusting the refresh rate between 1Hz and 120Hz according to the content.Samsung's display technology in the S24 Ultra is widely regarded as one of the best in the industry, offering vivid colors, deep blacks, and excellent brightness levels. The Galaxy S24 Ultra is capable of peak brightness up to about 1750 to 1900 nits in typical peak scenarios, although it may reach higher levels briefly under certain conditions to fight glare and enhance sunlight legibility, but generally below Xiaomi 15 Pro's peak brightness claim.
The Galaxy S24 Ultra supports HDR10+ for dynamic tone mapping and better contrast in supported content. It also offers a wide color gamut covering DCI-P3, providing rich and accurate colors. The screen supports an under-display ultrasonic fingerprint sensor for biometrics and is coated with Gorilla Glass Victus 3 for durability. The display uses a 20:9 aspect ratio, providing a cinematic viewing experience while maintaining comfortable ergonomics.
Display Brightness and Visibility
One of the standout features of the Xiaomi 15 Pro's display is the extraordinarily high peak brightness of up to 3200 nits, which Xiaomi claims is focused on a significant portion of the display area. This makes the Xiaomi particularly capable in extremely bright environments, such as direct sunlight, ensuring content remains visible without dimming or glare issues. By contrast, the Samsung Galaxy S24 Ultra display offers excellent brightness but generally peaks lower than Xiaomi's figure in real-world use, typically around 1750 to 1900 nits, which is already very bright but less than Xiaomi's extreme brightness.Both phones employ adaptive brightness technology to optimize screen visibility and power efficiency. Xiaomi's custom M9 panel is designed for ultra-high brightness with comparative power efficiency improvements, while Samsung's Dynamic AMOLED 2X is optimized for consistent brightness and color accuracy in various lighting conditions.
Display Color and HDR Support
Both flagship displays deliver excellent color reproduction with wide color gamuts. The Xiaomi 15 Pro supports up to 68 billion colors, while the S24 Ultra covers the DCI-P3 color space, both suitable for immersive and vivid multimedia consumption. They feature HDR10+ certification, enabling them to render HDR content with dynamic tone mapping for enhanced contrast and detail in highlights and shadows.Xiaomi's addition of Dolby Vision support enables better HDR performance on compatible streaming platforms, providing richer colors and more precise brightness control compared to HDR10+ alone. Samsung also emphasizes HDR performance but does not include Dolby Vision, relying on its proprietary HDR10+ technology for HDR content.
Refresh Rate and Smoothness
Both the Xiaomi 15 Pro and Samsung Galaxy S24 Ultra use adaptive LTPO AMOLED displays with a 120Hz refresh rate. This technology allows the refresh rate to dynamically scale between 1Hz and 120Hz depending on the displayed content to save power when a high refresh rate is unnecessary.This ensures both devices offer smooth animations, responsive scrolling, and enhanced gaming or video playback experiences. The Xiaomi 15 Pro additionally boasts a high touch sampling rate (up to 300Hz in some reports), which may benefit gaming responsiveness, though Samsung's screen also features excellent touch responsiveness optimized for high-performance use.
Display Design and Protection
The Xiaomi 15 Pro display is slightly smaller at around 6.73 inches compared to the Samsung's 6.8 inches, but both feature large, immersive screens with minimal bezels and a high screen-to-body ratio above 90%. Both phones feature curved edges, though Xiaomi's screen is sometimes described as having flatter panels compared to Samsung's pronounced curvature, impacting ergonomics and aesthetic preferences.For protection, Xiaomi uses the latest generation shatterproof glass (2024 generation), while Samsung applies Gorilla Glass Victus 3, one of the toughest commercially available glasses, enhancing drop and scratch resistance. Both offer IP68-rated water and dust resistance, ensuring ruggedness alongside their premium display offerings.
Display Additional Features
The Xiaomi 15 Pro benefits from several certifications from TÃV Rheinland, including low blue light, flicker-free technology, and circadian rhythm-friendly settings, which may help reduce eye fatigue during prolonged usage and improve night-time viewing comfort.Samsung's Galaxy S24 Ultra also invests heavily in display quality enhancements with features like Vision Booster technology, an improved adaptive display calibration system, and advanced AI-based optimization to deliver consistent brightness, color accuracy, and contrast under varying environments.
Both phones provide always-on display functionalities, enabling quick glanceable information without unlocking, with Samsung historically offering deeper customization options through its One UI software.
Summary
The Xiaomi 15 Pro display stands out with its extremely high peak brightness of up to 3200 nits, Dolby Vision support, and an ultra-wide color depth covering 68 billion colors, making it highly suited for HDR content consumption and outdoor visibility. It uses a Xiaomi-custom M9 AMOLED panel designed for high brightness efficiency with advanced TÃV certifications for eye comfort.The Samsung Galaxy S24 Ultra features a slightly larger Dynamic AMOLED 2X display with excellent color accuracy, a peak brightness typically ranging around 1750 to 1900 nits, and HDR10+ support. Its glass protection and display tuning are among the best in the industry, offering a premium viewing experience with a strong balance of brightness, color fidelity, and durability.
Both devices provide flagship-grade LTPO 120Hz adaptive refresh rate technology with smooth touch response and AMOLED contrast advantages. The choice between them would largely depend on preferences regarding peak brightness needs (Xiaomi leads), ecosystem and software customization (favoring Samsung), and overall design cues.
This comparison highlights that Xiaomi 15 Pro targets extremely bright, HDR-rich display performance, while Samsung S24 Ultra balances high fidelity color accuracy and robust durability in its display implementation.
