High Dynamic Range (HDR) monitor technology has been gaining popularity over the past few years, but is it really better than standard non-HDR monitors? With some monitors supporting HDR and others not, it can be confusing to know which is the right choice for your needs and budget. This comprehensive guide examines the key differences between HDR and non-HDR monitors to help you decide.
What is HDR?
HDR stands for High Dynamic Range. HDR monitors aim to create a more life-like viewing experience by producing images with a wider range of brightness levels and color depth than standard non-HDR monitors.
Some key advantages of HDR include:
- Higher Brightness – HDR monitors can achieve peak brightness up to 1000 nits, compared to just 100-350 nits on most non-HDR monitors. This allows for more vivid, intense whites and highlights.
- Wider Color Gamut – HDR monitors typically support wide color gamuts like DCI-P3 or Rec 2020 which allow more colors to be displayed on screen. Non-HDR is usually limited to the sRGB color space.
- Higher Bit Depth – HDR uses 10-bit or even 12-bit color for smoother color gradations and reduced banding artifacts. Non-HDR is typically 8-bit color depth.
- Increased Dynamic Range – With higher brightness capabilities and deeper blacks, HDR can truly showcase bright specular highlights and dark shadow details in a single scene. This mimics how we see the real world.
By having all these expanded visual capabilities, HDR video content can reveal details and colors you‘ve never seen before on non-HDR displays. It leads to a much more immersive, life-like viewing experience.
What is Non-HDR?
Non-HDR refers to standard dynamic range monitors that do not support HDR. Most monitors over the past decade have fallen into this category.
Key characteristics of non-HDR monitors include:
- Lower Brightness – Usually max out at 100 to 350 nits peak brightness. Cannot display intense specular highlights.
- Smaller Color Gamuts – Limited mostly to sRGB rather than wide gamuts like DCI-P3. Show a reduced range of colors.
- 8-bit Color Depth – Use 8 bits per color channel. More prone to color banding artifacts in gradients.
- Lower Dynamic Range – Dimmer bright areas and weaker dark details in a single scene. Less life-like image.
While non-HDR monitors have served users well for many years, they simply cannot match the visual experience that HDR capable displays can provide. But non-HDR monitors still have their place for more casual users.
HDR vs. Non-HDR – Brightness Comparison
One of the biggest differences between HDR and non-HDR monitors comes down to brightness. HDR monitors can get significantly brighter than non-HDR displays.
Brightness is measured in units called nits. Most non-HDR monitors have a peak brightness around 100 to 350 nits. On the other hand, HDR monitors can reach anywhere from 500 to 1000 nits peak brightness.
For example, the popular ASUS ROG Strix XG27UQ gaming monitor supports HDR with a peak brightness of 600 nits. Comparatively, the ASUS VG27AQ non-HDR monitor has a peak brightness of just 350 nits under the same conditions.
Why does this brightness difference matter? Firstly, it allows HDR monitors to truly make highlights in the image "pop" with intense brightness – like sun glinting off a car or water shimmering brightly. These realistic high brightness areas are just not possible on non-HDR monitors.
Secondly, this increased headroom to show bright highlights also enables HDR monitors to deliver much deeper, darker blacks in the same scene. This creates a high dynamic range that mimics real life more closely.
So in summary, the higher peak brightness abilities of HDR monitors create a more life-like contrast with bright vivid highlights against inky deep blacks – a stunning visual treat!
Color Gamut Comparison
Beyond just brightness, HDR and non-HDR monitors also differ significantly when it comes to reproducing colors accurately.
HDR monitors are capable of displaying a wider range of colors thanks to their support for wide color gamuts like DCI-P3 and Rec 2020. These gamuts encompass a much broader spectrum of colors compared to the standard sRGB gamut on non-HDR displays.
For example, a high-end HDR monitor like the ASUS ProArt PA32UCX supports 97% of the DCI-P3 color space. This allows it to display deeper more saturated reds, greens and blues than possible on a sRGB monitor. Vibrant wide gamut colors really make images come alive with realism.
Most non-HDR monitors only support around 100% of the sRGB color gamut. While sRGB is fine for general use, it is quite limited compared to cinema or photography standards. sRGB only allows displaying about 35% of what the human eye can see in the real world!
So if color accuracy is important to you – like for photography, graphic design or video work – then choosing an HDR monitor with a wide color gamut is highly recommended. The expansive colors offered by HDR monitors like P3 or Rec 2020 demonstrate shades simply not visible in non-HDR sRGB.
Improved Color Depth
Speaking of color accuracy, another advantage of HDR monitors is their use of 10-bit or even 12-bit color depth rather than the 8-bit depth used in non-HDR displays.
What does this mean? Well the color depth refers to the number of distinct red, green and blue shades that a monitor can produce per color channel.
- 8-bit color offers 256 possible shades of red, green and blue. Combining these shades generates around 16.7 million possible colors.
- 10-bit color massively increases this to 1024 shades per channel, leading to over 1 billion possible color combinations!
This huge leap from 8-bit to 10-bit color depth results in a much smoother, more natural color gradient. Banding artifacts are also dramatically reduced. This leads to extremely accurate color reproduction critical for color sensitive work.
Most consumer non-HDR monitors only support 8-bit color depth. A few high-end models may offer 10-bit support, but often only with chroma subsampling which can negatively affect text clarity.
Meanwhile, 10-bit or 12-bit color is pretty much standard across HDR monitors, no compromises required. So if you want truly accurate, smooth color gradations, HDR‘s increased color depth is highly advantageous.
Dynamic Range Capabilities
Finally, a core strength of HDR monitors lies in their elevated dynamic range capabilities. This refers to their ability to display a wide spectrum of brightness levels from deep darks to intense brights in a single scene.
As we‘ve discussed already, HDR monitors can hit far higher brightness levels around 500-1000 nits. This unlocks vivid lifelike highlights in images. Areas like sunlight gleaming off glass or water can dazzle with their peak intensities.
At the same time, HDR‘s improved contrast ratios enabled by local dimming allow portions of the screen to produce much deeper blacks. This adds realistic shadow detail that would just look crushed on non-HDR panels.
The combination of higher peak brightness and deeper blacks in a single frame gives HDR monitors a dynamic range closer to what we see in the real world. This level of realism is just not possible on standard non-HDR displays with their 100-350 nit brightness ceilings and weaker contrast ratios.
So for movies, games and other content where high dynamic range really enhances the visuals, HDR monitors are the clear winners over non-HDR alternatives. Scenes with both bright and dark elements will truly come alive with the expanded dynamic range that HDR provides.

Meanwhile, non-HDR monitors provide a more affordable option that still looks decent for everyday use despite their limitations. Just don‘t expect the same stunning visuals as a good HDR monitor.
When is HDR Most Beneficial?
Given the strengths and weaknesses summarized above, here are the main situations where investing in an HDR monitor makes the most sense:
- For watching HDR movies and TV shows via streaming services or Ultra HD Blu-ray where you want the full cinematic visual experience
- Playing HDR compatible games on consoles or PC where higher brightness, contrast and wide colors can elevate immersion
- Professional visual work like photography, video or graphics where color accuracy is paramount
- If you simply want the best, most realistic and future-proof monitor visuals possible
Of course, you need the full HDR ecosystem for maximum benefit – an HDR monitor, HDR source content and devices/cables that support end-to-end HDR signals.
When is Non-HDR Sufficient?
Here are some examples where a non-HDR monitor may be perfectly fine:
- General office work, web browsing and productivity applications
- Content consumption where ultimate image accuracy is not critical – news, social media etc
- Casual gaming where you prioritize high refresh rates over visuals
- Public display situations like digital signage or menus where HDR is not necessary
- Budget constrained situations where non-HDR provides good enough quality for the price
For these more everyday usages without a critical need for color accuracy or immersive contrast, a standard non-HDR monitor is likely sufficient. Just recognize you won‘t get quite the same wow factor for videos and games as a comparable HDR monitor.
HDR Monitor Buying Tips
If you‘ve decided to invest in an HDR monitor, keep these tips in mind while shopping:
- Aim for at least 500 nits peak brightness – For solid HDR performance, look for monitors rated for 500 nits or higher. This ensures vivid highlights.
- Look for wide color gamut support – DCI-P3 and Rec 2020 gamuts provide a broad spectrum of colors for accuracy.
- Ensure full 10-bit color – 10-bit color depth prevents banding issues with smooth gradients.
- Check your content sources – Make sure the monitor matches the HDR standards used by your Blu-ray, streaming or gaming devices.
- Compare HDR standards – Understand if a monitor uses basic HDR10, advanced HDR10+ or Dolby Vision and what tradeoffs they offer.
- Pick the right screen size – Consider what size screen works best based on your preferred viewing distance and content.
- Know your budget – HDR features require premium pricing, but mid-range models can still provide good performance.
Following these tips will help narrow down the many HDR monitor options to the right model providing the visual performance you desire.
HDR vs Non-HDR – Conclusion
While non-HDR monitors are certainly serviceable for everyday use, there is no denying that HDR displays are the superior choice if visual accuracy, contrast and immersiveness matter to you.
By supporting far higher brightness levels, a wider spectrum of colors, increased color depth and elevated dynamic range capabilities, HDR monitors simply provide a more life-like, engaging viewing experience compared to non-HDR alternatives – especially for movies and games.
If you are looking for the absolute best monitor technology available today offering a taste of the future, HDR is certainly worth the investment. Just be sure to select a monitor with strong enough HDR specifications and pair it with HDR content sources to unlock its full capabilities.
For more casual users who don‘t require ultimate color accuracy or contrast, non-HDR monitors can potentially save you money while still providing a pleasant viewing experience for general tasks.
Either way, understanding the key differences in brightness, color gamut, color depth and dynamic range is important to pick the right HDR or non-HDR monitor for your needs and budget. This guide equips you with the knowledge to choose wisely!
