A road to the black 8K resolution can really develop it?

The concept of resolution hasn't always been a key factor in consumer decisions. In the CRT era, people didnâ€™t prioritize resolution; instead, they focused more on screen size and clarity. Back then, the main concern was how many lines the TV could display, which was a measure of sharpness. For the consumer market, the basic hierarchy has remained consistent: screen size first, followed by resolution, and then contrast, color, and other features. This logic hasnâ€™t changed much over time.

Can 8K really take off?

Resolution has long been the most traditional upgrade path. It's an upgrade that consumers easily understand. Even though not everyone knows what 4K means, the idea of higher resolution is more familiar than concepts like HDR or quantum dots. As a result, many display manufacturers are willing to experiment with resolution upgrades.

The CRT era lacked clear definition

However, this development isnâ€™t uniform across all display technologies. While 4K is now common in LCDs, 4K projectors remain expensive and rare. The drop in LCD panel prices, along with increased production capacity, has made high-resolution displays more accessible. This has helped accelerate the rise of higher resolutions in recent years.

8K is the highest resolution available today

With this context, 8K products have started to emerge. But will resolution continue to be the main driver of innovation? Will consumers keep buying it? Today, we explore these questions.

What kind of support does 8K need behind the scenes?

As display technology evolves, so does resolution. From 1080P becoming standard in the LCD era, to the rush for 4K in OLED devices, resolution keeps changing. Theoretically, higher resolution means a clearer image. But on a small screen, like a 5-inch device, the difference between 2K and 4K is barely noticeable to the average user.

High resolution on small screens brings its own challenges

So, upgrading resolution also requires a larger screen. Otherwise, the benefits are lost, and the image quality might even suffer. For example, a 32-inch 4K monitor can make text and icons too small to be practical, which neither Windows nor macOS fully addresses.

High resolution demands strong hardware

Moreover, high-resolution content requires more storage space and faster transmission speeds. Even today, most personal computers struggle to handle 4K displays without top-tier graphics cards and ample memory. And for 8K, you'd need two high-end GPUs working togetherâ€”making it very costly.

Storage is another challenge. A few seconds of 8K video can take up several gigabytes, and while large hard drives are affordable, storing full-length 8K content is still a stretch. Given these limitations, 8K may not be suitable for individual consumers. But what about commercial applications? Could ultra-high resolution find a place there?

Changing perspectives, exploring new directions

In the commercial sector, high-resolution screens have real value. Fields like medicine, retail, and advertising benefit from the ability to show fine details. Plus, if the system doesnâ€™t need to run complex software like a PC, the costs can be significantly reduced.

High-resolution in automotive applications

Many smart TVs now support 4K playback, and the cost of Android systems is low. Upgrading such systems can meet the needs of high-resolution content. With streaming services, memory issues can be mitigated, especially as 5G networks improve, making data transfer faster and more reliable.

Ultra-high resolution isnâ€™t for the average consumer

Itâ€™s also important to note that only the commercial sector can afford high-priced display devices. Regular consumers likely wonâ€™t support the high cost of 8K. Therefore, the personal market for high-resolution displays may remain a niche, appealing only to a few high-end buyers.

Looking ahead, resolution isnâ€™t the only direction. Screen size, color accuracy, and other features might better capture the interest of everyday users. After all, without proper content, the benefits of 8K are limited. Features like HDR, on the other hand, offer more tangible improvements for the average person.

In short, blindly pushing resolution upgrades without considering real-world demand is unwise. Itâ€™s similar to how Nokia focused on call quality and battery life but missed the shift to smartphones. People care more about whether a product meets their needs than just its specs. Innovation must align with actual usage, not just technical advancement.

EI 35 Transformer
