3440 x 1440 Resolution [Everything You Need To Know]

16:9 monitors not wide enough?

Looking to go even wider with an ultrawide?

A monitor with a 3440 x 1440 resolution might be the way to go for you, but there are some things you should know before going all in.

What is 3440 x 1440 resolution?

The 3440 x 1440 resolution ​has an ultrawide aspect ratio of 21:9. This resolution and the 2560 x 1080 resolution are the two most common with a 21:9 ratio.

It’s much wider than the common 16:9 ratio that most monitors nowadays have.

3440 X 1440 Comparisons
The 3440 x 1440 resolution compared to 1920 x 1080, 2560 x 1080, and 2560 x 1440.

You can visualize above how much wider ultrawide resolutions are versus their 16:9 cousins.

The 3440 x 1440 resolution is 29.3% wider than it’s 2560 x 1440 counterpart.

Is it 4K?


It should not be confused with the 3840 × 2160 resolution which is officially referred to as 4K.

While the numbers look similar at a glance. It’s pretty far from it.

The 3440 x 1440 resolution contains 4,953,600 pixels whereas a 4K resolution has 8,294,400 pixels.

That’s a difference of 50.4% or 3,340,800 pixels!

Also 4K has an aspect ratio of 16:9 and not 21:9.

3440x1440 for gaming?

This is a pretty obscure resolution and uncommon for gaming.

That’s not to say they are impossible to find, but there are only a handful of monitors with high refresh rates with this resolution. Also they are pretty expensive.

With that said.

They are absolutely incredible at immersing you in a game. Especially if you go for a curved one.

If you want one for gaming then the first thing you should know is whether your current graphics card will be able to handle the increase in pixels.

If it won’t then you’ll end up with a bigger monitor, but a choppy lackluster gaming experience.

Look up benchmarks of your card performing at the resolution to get a rough idea of what you’re getting yourself into.

The hit in framerate will also depend on the actual game and the settings of course.

Holding system specs and in game settings consistent and comparing the two we can get an idea how much of an impact it could have.

For example, upgrading from 2560 x 1440 to 3440 x 1440 and using the Rise of the Tomb Raider to benchmark you can see average frame rate drop from 114 to 94 FPS.

That’s a drop of 24%.

Definitely a considerable amount. So keep an eye on your graphics card to avoid future frustration.
