WHAT IS A QHD MONITOR?
A QHD (Quad High Definition) monitor is a high-end PC accessory that can display 2560x1440 pixels at a 16x9 aspect ratio, which is four times the quality of 720p standard high definition. An Ultra Wide QHD monitor boosts the horizontal pixels to 3440, giving you a 21x9 aspect ratio. You’ll sometimes see QHD referred to as a Quad HD monitor.
The entire range has a variety of connectivity options to ensure your monitor can be plugged into any desktop PC or laptop.
When gamers look for a new screen, a QHD monitor is the perfect choice for them, because of their size and quality, and they are suitable for most mid-range gaming setups. The majority of mid-range graphics cards can handle putting a game on a QHD monitor at 30 FPS in 2K resolution.
What's a full HD monitor?
What's a Full HD monitor? The simple answer is one with 1080p image resolution. But there's more to know than just that. Here's a simple tutorial to help you decide if Full HD – or other options such as plain HD or QHD or UHD – is the best option for your new computer monitor.
HD vs. Full HD vs. Quad HD vs. Ultra HD and 4K
When it comes to display screens, the more pixels the better. Why? Because all else being equal, an image with more pixels can be can be displayed at larger sizes without suffering picture degradation.
Here are the four most popular types of display definitions today. All of them have 16:9 aspect ratios and qualify as high resolution displays, but to varying degrees:
HD: 720p image resolution (1,280 pixels wide x 720 pixels tall – approx. 1 million total pixels)
Full HD (FHD): 1080p image resolution (1,920 x 1,080 – approx. 2 million total pixels)
Quad HD (QHD): 1440p image resolution (2,560 x 1,440 – approx. 4 million total pixels)
Ultra HD (UHD)/4K: 2160p image resolution (3,840 x 2,160 – approx. 8 million total pixels)
Note that Quad HD offers four times the resolution as regular HD, and Ultra HD/4K offers four times the resolution as Full HD. There's another type of HD, called 4K, that's specific to movie theater and cinematic displays and has slightly higher pixel totals (it uses an even wider, 256:135 aspect ratio). Yet many consumer-level manufacturers use the terms Ultra HD and 4K interchangeably. Similarly, the term HD is sometimes used to describe both 720p and 1080p displays, but the term Full HD is used only to describe 1080p-level models.
