What Makes A Monitor 4k? 

To go any further, some terms need to be explained to know more about your screen resolution. 

Pixel – A pixel is the smallest controllable element of a picture represented on the screen. More pixel density typically provides more accurate image quality. 

Resolution – This is the screen size measured by pixels. Suppose your pc monitor has 1920 x 1080 resolution. This implies that the display is being shown at 1920 pixels horizontally and 1080 pixels vertically.

Native Resolution – The native resolution is the physical number of pixels, and this number is usually the highest resolution of your display. If you know the native resolution of your monitor, you are able to get a high definition picture quickly. The high-end gaming monitors come in high resolution, such as 5120 x 2880 (5k) or 3840 x 2160 (4k). 

So, a 4k monitor or Ultra HD or UHD TV or Ultra HD Blu-ray – all these refer to the same resolution, and it is 3840 x 2160 resolution. Or you can say 2160p. The full HD 1080p image on your HD TV is only 1920 x 1080. So, your 4k screens can display four times than 1080p. Again, there is also a DCI 4k. 

The pixel density of 4k is around 140 PPI, and the pixel pitch is about 0.18 mm. You will need high-speed cables for 4k. The RCA cables cannot carry a standard HD signal, and so the upgraded HDMI 1.4 connectors support 4k resolution at 30 frames per second(fps). 

The refresh rate for most 4k monitors ranges from 65hz to 75hz refresh rate. However, the gamers would prefer a high Hz display with 144Hz or 240 Hz.

Why Should I Consider Buying A 4K Monitor?

Nowadays, the newer monitors or more giant TVs (typically 50 inches and above) have 8 million pixels for 4k ultra HD. 

Generally, 4K sounds high tech and impressive quality. But let us clear you one thing. We have a misconception that higher resolution always means – it looks better. A better display depends on a high dynamic range, contrast ratio, better color, quantum dot, and so on. So, do not judge your display resolution quality without giving importance to these factors. 

Now you get why it is essential to know what monitor resolution is.

However, 4k screens are noticeably sharper than 1080p screens. You can enjoy better clarity and vibrancy. Your display can get a bigger work surface without a loss in pixel per inch. Your digital snaps are taken at a higher resolution.

So, when you see them onscreen, it will be quite fun and convenient for your eyes. You don’t have to squeeze your eyeball! 4k supports faster frame rates, insane contrast dynamics, and extended colors. However, there are many Blu-ray disc players that upscale 1080p Blu-ray disc to 4k. 

But if you used to sit pretty close to your HD monitors, you might not see the difference between 4k monitors and 1080p. So, your viewing distance matters when you are judging the picture quality of HD or Ultra HD. Again, you need to check whether your monitor is G-sync or Free sync. Because G-sync monitors need an extra Nvidia GeForce chip, whereas the Free sync monitors don’t need it.
