Can My Laptop Output 4K Signal?

Let’s clear out some misconceptions- your laptop doesn’t need to have a 4k screen in order to output 4k.

The screen of your laptop may be 768p or 1080p, but the display adapter or graphics card is capable of outputting much higher resolutions.

Even low-end graphics cards from nearly a decade ago can output in 4k or higher. How do you think all those multi-monitor setups work? Having 4 1080p displays is the equivalent of a single 4k display in terms of pixel count.

So yes, if your laptop has an HDMI 1.4 or newer port, it definitely can output in 4k. And most laptops released after 2012 should have HDMI 1.4, as the standard itself came out in 2009.

Now whether you’ll have a satisfactory experience or not is a totally different story. If you’re trying to stream or play 4k video content, you need at least a decent dual-core processor (preferably with hyperthreading/ SMT).

To ensure a lag-free experience within 4k movies and streams, you need a quad-core or higher. And for 4k gaming, you need a good dedicated graphics card.

4K vs 1440p vs 1080p | What’s The Difference?

It’s all about the pixels. As you know, everything you see on your LCD or OLED TV/ monitor is made up of little dots in the screen called pixels.

More dots means more detail. Fewer dots means jaggy images. A 1080p display has a resolution of 1920 x 1080, meaning 1920 pixels wide and 1080 pixels tall.

This is of course with a standard 16:9 aspect ratio. An ultra-wide 21:9 1080p display will have a resolution of 2560 x 1080. 

A 1440p display (16:0 aspect ratio) has a resolution of 2560 x 1440. It’s also known as a QHD display or WQHD display.

Many consider 1440p to be the ideal resolution since it provides significantly better detail than 1080p, but it is also relatively affordable compared to 4k displays.

Plus, most graphics cards will have a much easier time gaming at 1440p instead of 4k. For a gamer, 1440p at 120Hz or 144Hz is the ideal balance of resolution and refresh rate.

UHD or ultra HD is what we call 4k or 2160p. It has a resolution of 3840 x 2160 (16:0 aspect ratio). There are 4k IPS panels, as well as OLED panels.

OLED has more vibrant colors, much higher brightness, superior pixel response times, and the best viewing angles. However, it’s also more expensive.

At the time of writing this article, OLED is a technology reserved primarily for TVs and phones. There aren’t many commercial OLED PC monitors that we’ve heard of.

Is 4K Worth It?

Depends on what you’re doing and the type of experience you’re looking for. If you’re a gamer or casual PC user who just wants to watch movies and stream content, 4k is something you can live without.

It isn’t a necessity, but it sure makes your experience a lot better. You have to decide if the additional cost of a 4k capable display is worth it for you.

These days, 4k is actually quite attainable for a significant chunk of the population (at least if you live in a 1st world country).

4k displays are getting cheaper each year, and many households have 4k TVs. Of course, not all 4k TVs are created equal. Some have better colors and brightness, but they cost more. 

If you’re a professional who works in a studio with photos and videos, you might be one of those people that “need” a good 4k display.

If you make a living out of working with 3D art, graphics, animations, etc. you might already have a 4k display. At your workplace, you will be provided a pro-grade 4k display by your studio/ company.

Frequently Asked Questions


In summary, if you have a laptop manufactured anytime in the last 6 years- yes, it can output 4k. Even the built-in display adapter, i.e. your processor’s iGPU is capable of outputting a 4k image to the screen.

However, being capable of displaying 4k isn’t the same as having a good experience at 4k. If you try 4k gaming on a 6-year-old laptop, the best it will do is a slideshow.

Even streaming 4k content can be hard on laptops that are old. If you want a good 4k experience, you need a relatively new laptop.
