UHD vs FHD: Detail Comparison

Screen Resolution

UHD, often called 4K, has a standard resolution of 3840 x 2160 pixels. Its pixel count is four times that of FHD and has approximately 8.3 million pixels, resulting in clear and detailed images with excellent clarity on this display.

FHD has a resolution of 1920 x 1080 pixels and has approximately 2.1 million pixels. It also offers good image and video quality, but its impact is evident on smaller screens.

Display Size

UHD is best for larger TVs, 50 inches and larger, where a more immersive viewing experience is desired as UHD delivers high-resolution sharp and detailed images on larger screens.

FHD is generally suitable for 32-inch to 49-inch and medium-sized TVs, where it provides good image quality. Nowadays, it is found in most laptop and mobile device displays because it strikes a balance between image quality and power efficiency.

Battery Life

UHD displays have a significantly higher number of pixels than FHD displays, requiring more power to display images and videos at this higher resolution. Display devices with this resolution consume more power, which reduces battery life. A UHD display consumes more power, and the graphics card and processor also have to work harder to display a higher resolution, resulting in more power consumption.

FHD displays have fewer pixels than UHD, so they generally require less power to display pictures and videos, resulting in longer battery life for devices with FHD screens. Because of its good battery life, it is used in many mobile phones and laptops.


The resolution of a UHD display is 3840×2160 pixels, which is more than the resolution of an FHD display. A UHD display can display FHD content without any problem. UHD compatibility requires using an appropriate cable and interface to handle that resolution. This requires HDMI 2.0 or higher, which supports the required bandwidth. Nowadays, UHD content such as 4K movies, TV shows, and videos is coming to the market. UHD content looks great, but viewing it requires a UHD-compatible display and a source that can provide UHD content.

The resolution of an FHD display is 1920×1080 pixels, which is much lower than UHD. It can technically display UHD content, but the quality suffers greatly, resulting in less-than-perfect sharpness and detail. Most common HDMI and display interfaces can easily support FHD content.

Color Accuracy

UHD displays have better color accuracy than FHD displays. Because UHD displays have more pixels, they reproduce a wider range of colors more accurately. Additionally, UHD displays often have better panel technology and calibration than FHD displays.

UHD displays support a wide color gamut, such as DCI-P3 or Rec. 2020, while FHD displays use a narrower color gamut, such as sRGB.

UHD displays have greater color depth than FHD displays. Because of this, UHD displays show more shades of each color.

UHD displays have smoother color grading than FHD displays. This makes the difference between different color tones less noticeable. This is important for displaying smooth gradients in images and videos.

Refresh Rate

Both UHD and FHD display Supports a variety of refresh rates. UHD displays have a higher refresh rate than FHD displays because UHD displays have more pixels. UHD displays support 60Hz, 120Hz, 144Hz, and 240Hz refresh rates but requires more powerful hardware to run. While the FHD display also supports 60Hz, 75Hz, 120Hz, 144Hz, and 240Hz refresh rates, it runs smoothly even on standard hardware.

GPU and CPU Requirement

UHD displays have a much higher resolution, which requires a more powerful GPU to render content at this higher resolution, achieve smooth performance, and run graphically demanding applications or games on UHD. Displays with UHD resolution have a comparatively lower impact on the CPU than the GPU.

Modern CPUs, quad-core or higher, can handle UHD displays without any significant lag. But multitasking or running CPU-intensive applications with UHD content requires a more powerful CPU as CPU power is critical in tasks like video editing or 3D rendering.

FHD displays have a lower resolution and do not require a more powerful GPU to render content at this resolution. Mid-range GPUs from the NVIDIA GTX series or AMD Radeon RX series are often sufficient for gaming and graphics tasks at FHD.

For FHD displays, the importance of the CPU may vary depending on the specific job. Most modern CPUs are capable of handling FHD displays without any problems. You require high-performance CPUs for tasks that rely heavily on the CPU, such as video encoding or scientific simulations.


UHD displays have more pixels than FHD displays. They need better parts and machines to make them. They cost more money. They are usually in expensive devices like big monitors, 4K TVs, and gaming laptops.

FHD displays have fewer pixels than UHD displays. They do not need strong parts and machines to run them. They cost less money. They are usually in cheaper devices like small monitors, HD TVs, and normal laptops.
