What is screen resolution?

Complete Guide to Different Types of Screen Resolution

When looking to improve your viewing experience, one of the most important criteria to consider is screen resolution.

In this article, we'll explore the different types of screen resolution , explain what each means, and help you make an informed choice based on the device you're using and your personal preferences.

Screen resolution definition:

Screen resolution refers to the number of pixels (the small units of color that make up the image) on the screen. The more pixels, the sharper and more detailed the image.

Typically, resolution is expressed in terms of width and height in pixels , such as 1920x1080 (Full HD) or 3840x2160 (4K).

Higher resolutions provide sharper images , but also require more power to process and display those images. This results in a better viewing experience, but it's essential to choose the resolution based on your usage and screen size.

HD resolution: 1280x720p

HD resolution is often the most affordable and common in entry-level products, including low-end TV screens and projectors. At 1280x720 pixels, it offers decent quality for smaller screen sizes or for bedroom or living room projectors.

• Pros : Good value for money, ideal for smaller spaces.
• Limitations : Less suitable for large screens or modern 4K movies. Image sharpness may be impaired on screens larger than 50 inches.

Full HD resolution: 1920x1080p

Full HD is now the standard for televisions, video projectors, and monitors. At 1920x1080 pixels, this resolution is ideal for most movies, series, and video games. It is particularly recommended for screens ranging from 32 to 60 inches, especially for those who want a clear and fluid image without breaking their budget.

• Pros : High quality for most uses. Excellent compatibility with streaming platforms like Netflix, Disney+, and Amazon Prime.
• Limitations : Starting to become insufficient for large screens or for those looking for ultra-precise definition.

4K Resolution: 3840x2160p

4K, or Ultra HD, is the standard for demanding users. At 3840x2160 pixels, it quadruples the pixel density of Full HD. 4K projectors are especially popular for living rooms and home theaters because they deliver an exceptionally clear image.

• Pros : Ideal for large screens (55 inches and above) or screening rooms, it allows you to fully enjoy 4K movies, video games and shows in high quality. In addition, 4K is ideal for users of streaming platforms.
• Limitations : Requires compatible equipment and a 4K content source. 4K devices remain more expensive.

8K Resolution: 7680x4320p

8K resolution is the highest resolution currently available on the market, at 7680x4320 pixels. While still relatively rare and expensive, it represents the future of image quality for large screens, high-end home theaters, and professional applications.

• Benefits : Virtually perfect image quality, ideal for very large screens or professional applications where every detail counts.
• Limitations : 8K is still little used in current content, and compatible hardware remains expensive.

Other less common resolutions

In addition to popular resolutions such as Full HD, 4K, and 8K, there are also intermediate resolutions such as QHD (2560x1440) and 2K (2048x1080) . These resolutions offer a compromise between quality and cost, with a higher pixel count than Full HD while being more affordable than 4K.

How to choose the right resolution according to use?

• Small room, small screen : HD or Full HD resolution is usually sufficient for small screen sizes (up to 40 inches).
• Living room or big screen : Opt for 4K if you have a screen of 55 inches or more to enjoy the best image quality. If you are a movie enthusiast, 4K is an ideal choice.
• Gaming : 4K resolution is highly recommended for gaming on consoles or high-end PCs to deliver smooth and detailed graphics.

Which resolution to choose?

Choosing a screen resolution depends on many factors, including your screen size, your budget, and your intended usage.

If you want an immersive experience, go for 4K, but if you're looking for a more affordable solution, Full HD is still a great option. 8K, while futuristic, is still at a stage of development that's more suited to professionals or high-end cinema enthusiasts.
