QHD vs. FHD on Laptops: The Differences Explained

I emphasize quiet a lot on this website how much different does a QHD display make over a FHD display so I thought I should explain it in more detail so you can make an informed decision and see if it’s well worth the extra cash.

A summary of the difference is shown below but we will go over these after:

FHD (1920×1080) QHD (2560×1440)
Resolution 2 million pixels 3.6 million pixels
Screen Real Estate Shows fewer rows and windows (e.g., 26-30 rows in Excel) More rows and windows visible (e.g., 40-45 rows in Excel)
Text and Visual Sharpness Good but less sharp, visible pixelation at close range Sharper text and crisper visuals, less eye strain
Multitasking Limited space for side-by-side windows Easily manage multiple full-sized windows
Gaming Experience Lower detail, narrower field of view in games Higher detail, wider field of view in supported games
Professional Work Fewer lines of code, limited timeline visibility in video editing More lines of code, better timeline and asset management for video editing

The key difference lies in the resolution and pixel density. FHD has a resolution of 1920×1080 pixels, while QHD has 2560×1440 pixels. This alone makes a huge difference in:

1. Screen Real Estate

Even with the display being of the same size, you get far more space with a QHD. This is due to the amount of pixels, more pixels mean objects can be rendered in smaller versions whilst still maintaining high quality and this in turn means more space

A QHD resolution display will on average get you around 45 visible rows.

Whereas a FHD resolution display, will get you around 30 rows.

On an FHD display, you might see around 26-30 rows in a standard Excel sheet. With QHD on the same physical screen size, you could see up to 40-45 rows, this means more efficient and productive environment since there’s much less need to scroll frequently. If you work with small data sheets, then it may not be worth doing the upgrade but if you work with large data sheets which you have to edit manually it makes a HUGE difference.

2. Better Multitasking with Higher Resolution

QHD Multitasking

With QHD, you can comfortably have two full-sized applications open side by side or even three. For example, you can have a PowerPoint presentation open while reviewing data in Excel or following along with a web browser:

FHD Multitasking

If you pull off the same set up on a FHD screen, as you can see in the figure, windows are more cramped and harder to read without resizing or overlapping.

3. Sharper Text and Better Visuals

  • Higher Pixel Density: On the same physical screen size (e.g., 15-inch or 27-inch), QHD displays will a much higher pixel density than FHD, making text sharper and visuals crisper. This reduces eye strain when you’re working for long sessions or for tasks that require reading or editing small text, like coding or document writing.

  • Design and Photo Editing: For graphic designers or photographers, QHD displays provide more detailed and accurate images. You will see finer details in photos, which is critical when working on image editing software like Photoshop or Illustrator. FHD displays might miss some finer details, which can be visible on a QHD screen. As an example, check out the following photo:
Note the dirty spots on the wall (circled in blue). If you can’t see them, then you’re probably using a low resolution display (FHD or HD+), the dark spots are very clear on QHD displays.

Color Space

Now, resolution isn’t related to color space. However, QHD displays are more likely to offer vibrant, accurate colors due to the typical pairing of higher resolutions with better panels (like high-quality IPS or OLED panels that support wider color gamuts like DCI-P3). I will write a post about this topic soon in more detail.

4. Enhanced Gaming Experience

For gaming, QHD displays offer several advantages over FHD:

  • Higher Detail in Games: At QHD resolution, games look way better compared to FHD. Textures are more detailed, and the overall image quality is much clearer. This is more true in open-world games, where environments are rich in detail. For example, in games like WoW the War Within or Cyberpunk 2077, the increase in resolution can provide more immersive visuals without needing to scale up to 4K. 

Wider Field of View: Some games support wider fields of view (FOV) at higher resolutions. On a QHD display, you may be able to see more of your surroundings which gives you a huge advantage especially in FPS games or PvP on MMORPG games. 

5. Productivity in Professional Work

For professions that require more screen space and detail, such as data analysts or content creators, the extra screen space from QHD makes a HUGE difference productivity wise.

  • Coding: Developers benefit from being able to view more lines of code at once. On an FHD display, you might see around 40-45 lines of code in an IDE (integrated development environment), whereas on a QHD display, you could see 60-70 lines, making it easier to track and understand large portions of code at a glance.

Video Editing with QHD

With QHD (2560×1440), you get a sharper image, allowing you to see more detail in your footage or designs, crucial for tasks like color grading and editing intricate visuals. Also, the larger workspace enables you to comfortably work with multiple windows or timelines side by side without feeling cramped.

Paired with a display that covers a wider color space like Adobe RGB or DCI-P3, picking the QHD display over the FHD becomes a no brainer.
