Screen size

Screen size of the AOC i2490

24P1: 24 inches

When you don't have a large desk, a 24-inch screen is large enough. When you're working on a school project, for example. You have enough space for 2 windows next to each other, like Microsoft Word and your internet browser. The 24P1 has a disadvantage. The monitor base is very large, so it doesn't fit on every desk. Make sure there's enough room and place the monitor in the center for the best setup.

Screen size of the AOC Q24P2Q

Q24P2Q: 24 inches

Just like the 24P1, the Q24P2Q has a 24-inch screen. You can open a spreadsheet and text document next to each other, for example. Or get started with amateur photo editing. The advantage the Q24P2Q has over the 24P1, is the smaller monitor base. It takes up less space, so you don't need an extra large desk.

Screen size of the AOC U2790PQU

U2790PQU: 27 inches

With the 27-inch screen of the U2790PQU, you benefit from a lot of screen space. You have a larger overview and more space to open windows next to each other. For example, when you edit a file in Adobe InDesign and you want to keep your text next to it in Word. The U2790PQU has the same monitor base as the 24P1, so make sure you have enough room on your desk.

Resolution

Full HD monitor from AOC

24P1: Full HD

The Full HD resolution of the 24P1 makes the monitor suitable for all your school work and business work. Think about typing reports and preparing presentations. A nice addition is the 100% coverage of the sRGB color space. You experience sharp and realistic colors this way, which makes the screen suitable for amateur photo editing.

QHD monitor from AOC

Q24P2Q: QHD

Thanks to the QHD resolution of the Q24P2Q, you experience images twice as sharp as in Full HD. Colors are more vibrant and details are displayed sharper. The QHD resolution has another advantage. Because you have more pixels, you also have more screen space. That's because the text and icons become smaller when the number of pixels increases. That way, you can open even more windows next to each other and it's even easier to multitask.

4K monitor from AOC

U2790PQU: 4K

With a 4K resolution, the U2790PQU has the sharpest images in terms of resolution. You experience the images twice as sharp as in QHD and 4 times sharper than in Full HD. This makes the U2790PQU suitable for both photo and video editing. You zoom in on details without losing much quality. 4K offers the same advantage as QHD. You have more pixels at your disposal, so you can open more windows or tabs next to each other.

Connectors

Connectors of the AOC i2490

24P1: 1x HDMI and 1x DisplayPort

Most laptops and desktops have one or more HDMI ports. It's still the most common connector, which makes the 24P1 suitable for every situation. Do you have an older computer without HDMI? No worries, you can use the VGA port. Because the 24P1 doesn't have a DisplayPort, this monitor isn't suitable for daisy chaining.

Connectors of the AOC Q24P2Q

Q24P2Q: 1x HDMI, 1x DisplayPort, and 1x VGA

With an HDMI, DisplayPort, and VGA port, it doesn't matter if you have an old or new desktop or laptop. With the Q24P2Q, you have the option to use one of the 3. That way, you keep other ports open for accessories like a projector. Thanks to the DisplayPort connector, the Q24P2Q is suitable for daisy chaining. That way, you easily connect a second screen directly to a second monitor and easily expand your screen space.

Connectors of the AOC U2790PQU

U2790PQU: 2x HDMI and 1x DisplayPort

The U2790PQU has 2 HDMI ports and 1 DisplayPort port. For the best 4K display, you use the HDMI 2.0 port or the DisplayPort 1.2 port. Just like the Q24P2Q, the U2790PQU is suitable for daisy chaining via the DisplayPort port. Connect the screen to a 24-inch monitor, for example. That way, you can use the U2790PQU as the most important screen and the other as your image library while you edit photos.

Brightness

Brightness of the AOC i2490

24P1: 250 nits

A bright screen ensures clear visibility and comfort. With a brightness of 250 nits, the 24P1 falls just short of this. Ambient light has a large effect on the visibility of the screen, like sunlight when you sit close to a window. Or when you work on a presentation until late. Due to the 250-nit brightness, the screen isn't as clearly visible in brightly-lit and dark rooms.

Brightness of the AOC Q24P2Q

Q24P2Q: 250 nits

Just like the 24P1, the Q24P2Q has a brightness of 250 nits. With this one, you experience the same disadvantages with ambient light or in a darker room. The advantage is that both monitors adapt to this with the adjustablility. When you're bothered by sunlight, you can tilt the screen. That way, you prevent reflections on your monitor during the day. In darker rooms, it's best to work with the lights on.

Brightness of the AOC U2790PQU

U2790PQU: 350 nits

The screen of the U2790PQU is always clearly visible with its 350-nit brightness, even in bright or dark rooms. A higher brightness also ensures a better color representation. In combination with the 4K resolution, you can do more detailed work. This makes the U2790PQU suitable for professional photo and video editing.

Conclusion

Are you looking for a high-quality monitor for school or your home office? Choose the 24P1, which meets all the basic requirements. The Q24P2Q offers a sharper resolution and the option for daisy chaining if you want to work on 2 screens. Do you want a large screen and are you getting started with professional photo and video editing in 4K? Choose the U2790PQU.
