You may have heard the term High Dynamic Range (HDR) thrown around recently in home entertainment circles. As televisions supporting this new video technology become more ubiquitous and affordable, now is the perfect time to consider upgrading to an HDR-capable TV.
But what exactly is HDR, and why should you care about it? In short, HDR radically elevates picture quality by expanding and enhancing your TV‘s brightness, contrast ratios, color spectrum, and sharpness. This guide will provide an in-depth look at HDR technology and outline six compelling reasons why buying an HDR television in 2023 should be a top priority.
Overview of High Dynamic Range and How It Improves Picture Quality
HDR stands for "High Dynamic Range" and refers to the expanded range of luminance (brightness/contrast) and chrominance (color) today‘s newest TVs can reproduce. In simpler terms, HDR televisions can display images that are significantly more bright, vivid, and realistic than non-HDR sets.
By using advanced display panels, backlighting technology, video processing, and purpose-built encoding protocols like HDR10 and Dolby Vision, HDR TVs generate pictures which much more closely mimic the incredible dynamics, nuance, and depth that human eyes can perceive in the real world.
While the jump from standard to high definition (SD to HD) and HD to 4K ultra high-definition (UHD) made onscreen images exponentially sharper and more detailed, HDR enriches picture quality in a totally different way. Its emphasis is not purely on resolution, but on enhancing brightness, shadow details, colors, contrasts, and textures simultaneously across the entire scale. This delivers images with unmatched realism, clarity, and wow-factor that need to be witnessed firsthand to fully appreciate.
Analysts and industry experts widely consider HDR to be as game-changing of a TV evolution as the introductions of color, HD, and UHD resolution. Adoption is rapidly accelerating, with receivers, discs, streaming devices, gaming consoles, and content providers rapidly updating to support HDR video signals. In 2023, virtually every new television from budget brands to flagship OLED models supports HDR. Even entry-level sets leverage basic HDR capabilities. That means prices are lower than ever, choice is plentiful, and picture quality is phenomenal regardless of your budget.
#1 Benefit: Far More Vivid, Precise and Impactful Colors
Boosting peak brightness is what grabs most headlines when it comes to HDR. But many experts argue that the expanded color capabilities of HDR televisions represent an even more transformative upgrade over conventional TVs.
Rather than simply hitting higher nit (brightness) levels, HDR‘s complete reconstruction of color depth, volume, saturation, accuracy, and luminance is what truly pushes image quality to the next frontier of realism. This table illustrates technical color differences between standard, UHD 4K, and 4K HDR televisions:
| Display Standard | Max Color Depth | Wide Color Gamut | 10-bit Panel | 12-bit Panel |
|---|---|---|---|---|
| SDR/Rec. 709 | 8-bit | No | No | No |
| UHD/Rec. 2020 | 10-bit | Yes | Yes | No |
| HDR10 | 10-bit | Yes | Yes | Yes |
| Dolby Vision | 12-bit | Yes | Yes | Yes |
As shown above, high dynamic range video leverages advances across the board to achieve superior color reproduction capabilities. This starts at the panel level, with TVs shifting from traditional 8-bit color depth to 10 bits or even 12 bits. Rather than displaying millions of colors, new units can generate over a billion combinations. This essentially eliminates gradient banding and color aliasing (false colors) by enabling flawlessly smooth blends and transitions between adjacent hues.
HDR also supports much wider color gamuts, abandoning old standards like Rec. 709 in favor of dramatically larger spectrums like DCI-P3 (used in commercial digital cinema projectors), Rec. 2020, or proprietary gamuts. Many premium TVs today cover over 95% of P3 which is over 40% larger than sRGB. By encompassing more shades, HDR prevents certain hues like vibrant greens and deep reds from getting clipped or undersaturated. Content mastered in HDR harnesses this to deliver images packed with nuanced tones that make SDR material look dull and lifeless by comparison.
Finally, elevated luminance ranges in HDR provide colors with far more perceptible brightness and punch. This gives the image an almost three-dimensional, window-like sense of depth that needs to be seen firsthand to fully appreciate. Whether displaying lush natural vistas, popping neon signs, or glinting metal surfaces, HDR‘s colors immediately grab attention while remaining naturalistic rather than oversaturated.
#2 Benefit: Massively Improved Brightness, Blacks, and Contrast
Contrast ratio refers to the luminance difference between the brightest highlight and darkest shadow a TV can reproduce. A higher number means more realistic, nuanced and detailed images thanks to retained clarity across dark and bright regions. Standard televisions struggle to exceed contrast ratios over 5000:1. However flagship HDR televisions boast ratios exceeding 1 million-to-one through precise local dimming algorithms.
That means shadows retain far more visible detail rather than getting crushed into black nothingness. Specular highlights like glinting glass, flames, or flickering bulbs also hold lifelike brightness and detail rather than blowing out into solid white blobs. HDR‘s increased precision across multiple zones of luminance gives filmed content the same epic sense of depth and visual richness that directors intended while filming.
Exceptionally deep black levels also contribute to the mesmerizing contrast HDR delivers. The best OLED TVs capable of perfectly turning off individual pixels on command to achieve infinite contrast ratios exceeding 20,000,000:1. Even LED-backlit LCD HDR televisions leverage sophisticated full-array local dimming (FALD) systems with 500+ zones to make blacks far darker. This prevents the light bleed and blooming issues around bright objects that plague non-HDR LED models.
On average, HDR televisions output around 1000 – 4000 nits at their peak compared to just 300-500 nits for conventional televisions. Some premium 2023 models exceed an incredible 2000+ nit brightness rating. While this sounds extremely complex, the simple fact is that HDR makes real-world colors, contrasts, details, and lighting effects come through far more impressively. Images possess a layered, nuanced richness simply unattainable without HDR‘s technical capabilities.
#3 Benefit: Far More Color Volume and Ability to Display the Full Rec. 2020 Gamut
As touched upon already, high dynamic range televisions are capable of reproducing a much larger subset of colors thanks to expanded bit-depths and cutting-edge Quantum Dot filters. While conventional LED-lit LCD televisions max out at around 70% coverage of the Rec. 709 color space, new QLED and OLED HDR models reach well over 90% coverage of the far larger DCI-P3 gamut.
Flagship Quantum Dot and organic light-emitting diode televisions even fully saturate over 75% of the vast Rec. 2020 color spectrum. This represents a nearly 30% boost in possible colors over standard UHD TVs. Images harness noticeably more color volume, avoiding the muted, undersaturated quality non-HDR movies frequently exhibit.
By supporting trillions more colors rather than just millions, scenes take on the same lush, vibrant yet accurate quality that real-world environments possess to human eyes. This expanded volume prevents situations where certain hues get clipped altogether by low bit-depth panels, yielding better color accuracy too. Skin tones, landscapes, and subtle lighting mixes appear far more lifelike as well thanks to HDR‘s boosted color precision and smoothness.
#4 Benefit: Even Non-HDR Content Gets Upscaled to HDR-Quality
High dynamic range televisions are backwards compatible, meaning they can display standard and high definition signals too, not just cutting-edge 4K HDR movies. Better yet, they actively upscale lower resolution, standard dynamic range material using advanced video processing and tone mapping technologies.
Powerful onboard SoC chipsets analyze aspects like average picture level, color information, frame complexity, and histogram data to intelligently map colors, adjust luminance, and expand contrast when displaying non-HDR content. This allows even older DVDs or cable broadcasts to exhibit some of the same HDR-esque vibrancy and depth that native HDR10 and Dolby Vision feeds unlock.
Of course upscaled SDR won‘t be quite as stellar as content mastered specifically for HDR color spaces and brightness levels. But it still reaps noticeable improvements compared to viewing on a conventional SDR television. That means early HDR adopters can benefit right away even before HDR films or shows become prevalent. It also futureproofs new purchases for several years down the line when HDR content becomes more ubiquitous.
|| Non-HDR 4K TV | Same Model With HDR |
|-|-|-|
|SDR Blu-Ray and 1080p Content | Decent but sometimes muted colors and detail, average contrast | Enhanced colors, improved contrasts and black levels, elevated brightness |
|HD Cable and Satellite Feeds | Prone to color banding, soft contrasts, dull brightness | More vivid colors thanks to 10 to 12-bit panels, better defined shadows and specular highlights |
|HDTV Sports Broadcasts | Visible noise in dark scenes, glare around bright objects | Lower noise thanks to better processing, more uniform brightness across the screen |
As shown in this table, the same 4K television model delivers a noticeably boosted picture across various types of standard dynamic range content when equipped with high dynamic range capabilities.
#5 Benefit: Far Better Contrast and Picture Clarity Even in Bright Room Environments
One common reservation shoppers have about upgrading to a newer higher-performance television is light management. Standard dynamic range LED sets struggle to overcome glare and reflections. Images frequently get drowned out in anything brighter than a dedicated darkened home theater. Big brightness numbers sound great on paper, but translate poorly to real-world conditions.
Thankfully, HDR television technology finally unlocks the brightness and contrast needed for truly brilliant images regardless of ambient lighting conditions. Sophisticated anti-reflective optical filters minimize glare. Smart lighting sensors and algorithms actually boost key areas of the image to counteract room brightness. Elevated peak brightness ratings reaching upwards of 2000 nits also simply override any washed-out quality.
Combine these advancements with perfect black levels courtesy of self-illuminating OLED panel technology, or full-array local dimming systems which boost contrast through independent backlight control, and HDR TVs deliver picture quality that isn‘t affected by real world conditions. Sporting events, streaming shows, and Blu-Rays hold the same epic contrast and color during daytime viewing as night. No longer are buyers forced to choose between display capabilities and practical room reflections. HDR empowers television viewing anytime, anywhere while still recreating images exactly as directors and colorists mastered them.
#6 Benefit: HDR Gaming Unlocks More Realistic, Responsive and Immersive Experiences
Modern video game consoles like the PlayStation 5 and Xbox Series X launched with built-in support for 4K graphics and HDR video processing. This allows video games to harness all the same expanded brightness, color and contrast benefits that films mastered in HDR provide. When playing games in HDR, details become clearer, colors appear more vibrant, and virtual environments seem to come alive thanks to enhanced realism.
Developers master releases specifically for HDR color spaces, ensuring lifelike color accuracy, intelligently raised peak brightness for standout sparks and effects, while still retaining rich, nuanced shadows. Expanded contrast better mimics how real world environments and textures interact with virtual light sources. Games calibrated for HDR televisions also minimize fatiguing qualities like blown out backgrounds or overly dim foreground elements.
Input lag reductions found on many premium 4K HDR televisions provide competitive multiplayer gamers with smoother, more responsive controls free of distracting display latency too. When combined with features tailormade for next-gen gaming like native 120Hz refresh rates for ultra-smooth visuals and variable refresh rate support to eliminate screen tearing, 4K HDR represents the ultimate showcase platform for modern consoles.
In many cases, the visual impact unlocked by high dynamic range gaming rivals the resolution jump from 1080p HD to 4K Ultra HD. HDR‘s expanded brightness, black levels, colors and contrast breathe new life into game worlds. Once experienced, it‘s tough to go back to gaming in standard dynamic range. Upgrading to an HDR television futureproofs your setup for this generation‘s best looking game releases.
This guide has just scratched the surface when it comes to examining high dynamic range technology and its multitude of picture quality benefits compared to standard televisions. While metrics like color gamuts, nit levels, and contrast ratios help quantify changes on paper, they fail to fully demonstrate the transformative visual impact HDR enables.
As with most display evolutions, HDR‘s capabilities need to be witnessed in person to fully register the massive gains in perceivable realism, depth, and beauty unlocked. Photos and written breakdowns simply cannot do justice to just how much more lively, intense, and true-to-life imagery appears when mastered for High Dynamic Range displays.
If you are researching TV upgrades for 2023, make viewing HDR content firsthand a crucial evaluation step before purchasing. The choice between HDR versus non-HDR may very well eclipse resolution, size or brand loyalty considerations in terms of influence over your final television satisfaction. Once eyes behold HDR‘s colors, contrast and motion clarity improvementsoutineextra clarity in motion, inferior non-HDR televisions swiftly feel archaic and unsatisfying by comparison.
Thankfully HDR television adoption is accelerating rapidly. Prices cater to virtually every budget now with reasonable entry points under $500. Review sample floor models at local electronics stores exhibiting native 4K HDR Blu-Ray or streaming feeds for the best representation. We are confident witnessing high dynamic range in action will place upgrading high on your priority list!
