What is UHD?

Let us embark on our comparison journey, commencing with UHD—an abbreviation for Ultra High Definition—a pivotal indicator of display resolution. Resolution, in essence, signifies the amalgamation of horizontal and vertical pixels within a display, wherein each pixel functions as the fundamental unit of visual representation.
Perhaps the term Full HD resonates with you—a configuration boasting a resolution of 1920 × 1080 pixels, effectively encapsulating 1920 horizontal pixels intertwined with 1080 vertical counterparts. Consequently, a Full HD display accommodates a grand total of 2,073,600 pixels, or succinctly, 2 million pixels. Often, this display variant is colloquially referred to as a 1080P display, underscoring its vertical pixel configuration.
Enter UHD, where the pixel tally escalates fourfold, as it commands a resolution of 3840 × 2160 pixels—comprising 3840 horizontal pixels harmonizing with 2160 vertically arrayed ones. Much akin to its 1080P counterpart, UHD is also denoted as 2160P.
The UHD canvas boasts an impressive fourfold increase in pixel count compared to its 1080P kin—mathematically tallied as 3840 × 2160, which equates to a staggering 8,294,400 pixels or, in more colloquial terms, a remarkable 8 million pixels. Ergo, it frequently garners the title of a 4K display, or with precise technical articulation, a 4K UHD display.
This elevated resolution engenders an environment where images emerge with heightened clarity, vividness, and razor-sharp precision. Worth noting, this resolution remains indifferent to display dimensions. To illustrate, let us consider two prevalent TV sizes: 55 inches and 65 inches. Both of these varying expanse of visual realms can seamlessly embrace the UHD resolution.
However, a pivotal variable comes into play—the Pixel Density of the display, often denoted as pixels per inch (PPI). It constitutes the quotient between the display’s resolution and its physical screen size. As a result, a 65-inch 4K UHD TV may exhibit a slightly reduced pixel density compared to a 55-inch 4K UHD TV.

What is HDR?
Despite sharing the “HD” abbreviation, HDR and UHD are distinct realms. HDR, short for High Dynamic Range, is an innovation intricately tied to the dynamic range within an image, accentuating the brightest luminosities and the deepest shadows.
The motive of HDR lies in refining an picture’s assessment, luminosity, sharpness, and chromatic richness, fostering a heightened sense of realism and power. Through HDR’s lens, a display not only distinguishes vivid highlights within an image but does so without overpowering the overall composition.
Achieving this feat necessitates capturing imagery or videos in HDR format, wherein each frame encompasses supplementary metadata outlining brightness and contrast nuances. Armed with this data, the display engages in a dynamic optimization process for each frame during video playback, eschewing static brightness and contrast settings.
Elevating to this plateau demands that the display possesses augmented hardware capabilities for the decoding and exhibition of HDR content. Among the pantheon of renowned HDR formats, notable contenders include:
- Dolby Vision
- HLG (Hybrid Log-Gamma)
- HDR10
- HDR10+
Emerging from this constellation, Dolby Vision has surged as the frontrunner among HDR formats, garnering support from an array of TV manufacturers (LG, Sony, Panasonic, TCL, Vizio, and more), content creators, and streaming platforms (Ultra HD Blu-Ray Discs, Netflix, Disney+, HBO Max, etc.). Even the realm of gaming bears witness to the incorporation of HDR, with prominent AAA titles integrating support for this transformative technology.
Comparison: UHD vs HDR
| Concept | Description |
|---|---|
| UHD (Ultra High Definition) | Represents the number of pixels in a display; a significant jump in image/video quality from Full HD resolution. |
| HDR (High Dynamic Range) | Optimizes pixels for color, brightness, and contrast; dynamically adjusts parameters for each frame of video. |
UHD and HDR Capabilities
A 4K UHD TV can have HDR capabilities based on the display technology:
| Display Technology | HDR Implementation |
|---|---|
| OLED TVs (self-emissive) | Easy control of pixel brightness and contrast; most 4K UHD OLED TVs support HDR. |
| LCD Displays (with full-array local dimming) | Divides backlight into zones for individual control; high-end LCD TVs with this feature have HDR capabilities. |
| LCD Displays (partial dimming) | Less effective HDR implementation compared to full-array local dimming or OLED TVs. |
HDR vs UHD, which is Better?
Embracing the pinnacle of contemporary display technology, the fusion of 4K UHD and HDR reigns supreme. For those with the flexibility in their budget, the resplendence of an OLED Display emerges as an enticing choice, offering an exquisite interplay of colors, contrast, and expansive viewing angles. The harmonious integration of HDR further elevates this experience, ushering in an unrivaled realm of video quality.
The realm of 4K UHD and HDR extends beyond television screens, extending its influence to encompass computer monitors and laptop displays. Moreover, the horizon of visual possibilities is broadened by the advent of cutting-edge 4K projectors, hailed from reputable brands, which now proudly feature the HDR capability.
Undoubtedly, the investment in a 4K UHD Display or projector adorned with the splendor of HDR commands a higher price point in comparison to conventional UHD counterparts. The dynamic brightness adjustments intrinsic to HDR, occurring on a frame-by-frame basis, imbue these displays with a heightened energy appetite, a facet particularly pronounced when indulging in HDR-rich content playback.
