The concept of resolution hasn't always been a priority for consumers. In the CRT era, people didn’t focus much on resolution but rather on screen size. Back then, the number of lines—essentially a measure of sharpness—was more important than pixel density. For the consumer market, screen size was the primary concern, followed by resolution, and then factors like contrast and color. This development logic has remained largely unchanged over time.
Can 8K truly take off?
Resolution has long been the most traditional upgrade path in display technology. It's an upgrade that resonates well with consumers, even if not everyone fully understands what 4K or 8K means. Compared to more complex features like HDR or quantum dots, the story of resolution is simpler and more relatable. That’s why many display manufacturers are eager to push for higher resolutions.
The CRT era had an immature definition of resolution
Of course, this also reflects the broader progress of the display industry. Resolution upgrades haven’t always kept pace with other advancements. While 4K is now common in LCDs, 4K projectors are still rare and expensive. The drop in LCD panel prices, along with increased production, has helped drive resolution improvements in recent years.
8K is the highest resolution available in liquid crystal displays today
With that in mind, 8K products have started to emerge. But will resolution continue to be the main driver of innovation? Will consumers keep buying into it? Today, we explore these questions.
What support is needed for the 8K rush?
As display technologies evolve, so does resolution. From the rise of 1080P in the LCD era to the 4K boom in OLED devices, resolution has consistently improved. Higher resolution theoretically leads to sharper images, but on smaller screens, the difference between 2K and 4K can be nearly imperceptible to the average user.High resolution on small screens brings new challenges
Therefore, upgrading resolution must go hand-in-hand with increasing screen size. Otherwise, high resolution could actually hurt the viewing experience. For example, a 32-inch 4K display may make text and icons too small to be practical, which isn’t ideal for either Windows or macOS systems.High resolution demands strong hardware support
High-resolution content requires more storage, faster transmission, and better processing power. Even today, most PCs struggle with 4K displays, requiring top-tier graphics cards and high memory capacity. For 8K, two high-end graphics cards would be necessary, which is a costly investment.Storing just a few seconds of 8K content can take up gigabytes, and while TB-class hard drives are affordable, they’re still not enough for large-scale 8K content. Considering all this, 8K products may not be suitable for regular consumers. But what about commercial applications? Could ultra-high resolution have a future there?
Changing perspectives, looking ahead
In the commercial sector, high-resolution screens are valuable. Fields like medicine, retail, and digital signage benefit from the ability to show more detail. And unlike personal computing, commercial systems don’t need to be as powerful—especially when using streaming media, where memory issues can be mitigated with fast networks.High-resolution in automotive applications
Today, many smart TVs support 4K playback. The Android system used is relatively low-cost. Upgrading such systems can meet the needs of high-quality visuals without excessive costs. With 5G, streaming becomes more feasible, solving memory and bandwidth issues.Ultra-high resolution may not suit individual users
At the same time, only the commercial sector can afford high-priced display devices. Ordinary consumers may not see the value in 8K unless there's real content support. Features like HDR, on the other hand, offer more tangible benefits for everyday users.Therefore, blindly pushing resolution upgrades without considering user needs is unwise. It's similar to how Nokia focused on phone quality and battery life but missed the shift to smartphones. People care more about whether a product meets their needs than just its specs.
POE Adapter, also known as a Midspan, Power Injector, or PoE Charger, is a device that leverages Power over Ethernet (PoE) technology to transmit both power and data simultaneously over an Ethernet cable. This technology enables the delivery of electrical power along with data signals to powered devices (PDs) such as IP cameras, wireless access points (WAPs), and more, over a single Ethernet cable.
Applications
POE Adapters are widely used in scenarios requiring remote power supply and data transmission, such as intelligent security systems (IP camera surveillance), wireless network coverage (WAP deployment), VoIP telephony systems, and more. These applications often demand devices to be installed remotely without local power sources, making POE Adapters an ideal solution.
Selection Criteria
Compatibility: Ensure the POE Adapter is compatible with your network equipment, particularly in terms of PoE standards and power requirements.
Brand and Quality: Opt for reputable brands and high-quality products to guarantee stable and safe power supply.
Power Rating and Port Count: Choose a POE Adapter with the appropriate power rating and number of ports based on your specific needs.
