When it comes to buying a PC monitor, there are a few things you need to keep in mind. First, you need to decide what type of monitor you want. There are three main types of monitors: TN, IPS, and VA. TN monitors are the most common type of monitors. They have great refresh rates and low input lag, making them ideal for gaming. However, they also have poor colour accuracy and viewing angles. IPS monitors have better colour accuracy and viewing angles than TN monitors, but they also have higher input lag. VA monitors have the best colour accuracy and contrast ratios of any type of monitor, but they also have the highest input lag.
Once you've decided on the type of monitor you want, you need to look at the specs. Some of the key specs for a monitor include the size, refresh rate, the response time, and the resolution. Size is measured diagonally, corner to corner and bigger monitors typically offer more features, more ports for connectivity and better viewing angles but cost more and require more space. The refresh rate is how often the screen is refreshed, and is measured in Hertz. The response time is how long it takes for a pixel to change colour, and is measured in milliseconds. The resolution is the number of pixels on the screen, and is measured in pixels per inch.
When you're considering which monitor to buy, you also need to keep in mind what you'll be using it for. If you're a gamer, you'll want a monitor with a high refresh rate and low input lag. If you're a graphic designer, you'll want a monitor with great colour accuracy. And if you just want a general-purpose monitor, you'll want one with a high resolution. Keep in mind that the higher the resolution, the more pixels your computer needs to push to the screen and the more processing power this takes. So, whilst a 5K or 4K monitor produces stunning, crisp images, you need to make sure your PC is up to the job of producing the millions of pixels required every time a new image needs to be drawn on screen.
As well as traditional flat panel screens, you can also buy curved screens for a more immersive gaming or multimedia experience and reduced eye strain. These can produce more glare than standard monitors though so check both the light sources in the room and your position in relation to the monitor. Some monitors include touchscreen capabilities which gives you a more intuitive experience and is a compelling alternative to using a keyboard and mouse for some applications.
