The screen is pitch black. You cannot tell the TV is on. A single lantern flickers in the bottom left corner. On a lesser TV, this lantern would create a hazy "ghost" behind it. On Sony OLED, it is a pinpoint flame, with the wood grain on the lantern’s handle visible despite the surrounding abyss.
Avoid YouTube (compression kills fireworks HDR). Use lossless or high-bitrate demo files.
⚠️ Sony’s built-in media player (
Videoapp) sometimes struggles with very high bitrate HDR.
Better app: Install Kodi or VLC from Google Play Store on the TV. 4K HDR Fireworks Sony Oled TV Demo
Standard Dynamic Range (SDR) fireworks look like a painting of a firework. High Dynamic Range (HDR) fireworks look like a window to a firework.
Purpose: Evaluate the visual and technical performance of a Sony OLED TV during a 4K HDR fireworks demonstration to assess picture quality, HDR handling, motion, color accuracy, and viewing experience. The screen is pitch black
Date of demo: April 7, 2026
Test unit: Sony OLED TV (model unspecified — assume flagship-level OLED with HDR10/HLG and Dolby Vision support)
Source material: 4K HDR fireworks demo clip (high-dynamic-range mastering, wide color gamut)
Viewing conditions: Darkened home theater (ambient light <5 lux), viewing distance ~1.5× screen height, HDMI 2.1 input, HDR mode enabled, OLED pixel refresh allowed before test
The fireworks demo is the ultimate flex for OLED technology because, unlike LCDs, OLED pixels are self-emissive. They do not require a backlight. When a pixel needs to be black, it simply turns off. ⚠️ Sony’s built-in media player ( Video app)
In the "Fireworks" demo, this creates a stark, startling contrast. As the firework bursts, the pixels responsible for the explosion ignite to near-maximum brightness (often hitting peak luminance levels of 700 to 1000 nits). The pixels immediately adjacent to them, representing the night sky, remain completely off.
The visual result is a sensation of infinite depth. The blacks are not just "dark shades of grey"; they are voids. This "infinite contrast ratio" allows the HDR (High Dynamic Range) metadata to truly shine. HDR is all about the difference between the lightest and darkest parts of an image. By offering absolute darkness alongside searing brightness, the fireworks appear more three-dimensional, popping off the screen with a realism that other panel technologies struggle to replicate.
