When it comes to buying a new monitor, there are ample factors to consider first. While monitors with 480Hz refresh rates won’t be prevalent in the market for years to come, you still might want an image more fluid than the standard 60Hz. Alienware’s 34-inch displays, for instance, are capable of displaying 160 frames per second as per the 160Hz refresh rate.

More important to most users, however, is resolution. Whereas 60 frames per second is perfectly acceptable to the average gamer or worker bee, a crisper image is always welcome. That’s why we’ve sought out displays sporting not only 1,920 x 1,080 pixel resolutions, but those up to 4K as well – including some inbetweeners adhering to less conventional aspect ratios.
