75Hz high refresh rate satisfy both gaming and working
The first thing we need to establish is “What exactly is refresh rate?” Fortunately it isn’t very complex. Refresh rate is simply the number of times a display refreshes the image it shows per second. You can understand this by comparing it to frame rate in films or games. If a film is shot at 24 frames per second (as is the cinema standard), then the source content only shows 24 different images per second. Similarly, a display with a display rate of 60Hz shows 60 “frames” per second. It’s not really frames, because the display will refresh 60 times each second even if not a single pixel changes, and the display only shows the source fed to it. However, the analogy is still an easy way to understand the core concept behind refresh rate. A higher refresh rate therefore means the ability to handle a higher frame rate. Just remember, that the display only shows the source fed to it, and therefore, a higher refresh rate may not improve your experience if your refresh rate is already higher than the frame rate of your source.
Contrast Ratio
The contrast ratio refers to the difference between the maximum and minimum brightness. It is the capacity of the display monitor to show dark colors darker and bright colors brighter.
IPS: IPS panels do a decent job in the contrast ratio segment but they are nowhere close to that of VA panels. An IPS panel offers a contrast ratio of 1000:1. When you watch a black color environment in an IPS panel, the black color will be slightly greyed out.
VA: VA panels offer a superior contrast ratio of 6000:1 that is very impressive. It has the capacity to show dark environments as darker. So, you will enjoy the picture detailing shown by the VA panels.
The winner is VA panel because of its high contrast ratio of 6000:1.
Black Uniformity:
Black uniformity is a monitor’s ability to display black color throughout its screen.
IPS: IPS panels are not really great at displaying the uniform black color throughout the screen. Due to the low contrast ratio, the black color will appear slightly greyed out.
VA: VA panels have a good black uniformity. But it also depends on the TV model you go with. Not all TV models with a VA panel have good black uniformity. But it is safe to say that in general, VA panels have better black uniformity than an IPS panel.
The winner is the VA panel because it can display black color uniformly throughout the screen.
