It is hard to imagine working on a computer without a monitor. You can also connect one to your laptop if you need a larger screen. Since you use it for several hours a day, you should not rush or underestimate its selection.
When choosing a monitor, you should pay attention to the following parameters:
Size
This is the first specification to consider when choosing a monitor. It is given as the screen diagonal, usually measured in inches. Common monitor sizes range from approximately 20 to 32 inches. Simply put, the larger the monitor, the better. However, the largest monitors are mostly fully utilized by gamers or people working with video and graphics.
Aspect Ratio
The aspect ratio is partly related to screen size. The most common is 16:9, which corresponds to the human field of vision. The 16:10 ratio is also universal and suitable for both work and entertainment. For working with documents, a 4:3 or 5:4 ratio may be advantageous. If you need to work with two screens simultaneously, you can choose a 21:9 ratio. Such an ultra-wide monitor also provides a great experience for gaming or watching movies.
Resolution
Resolution is particularly important for larger monitors. Otherwise, the image may not be sharp enough. For typical diagonals from 20 to 27 inches, resolution should be at least Full HD. Otherwise, details may not appear clear enough. Keep in mind, however, that higher resolution requires more computer performance and naturally also increases the price.
Purpose of Use
Do you need a monitor for browsing the internet, gaming, or work? This should guide your choice of other parameters. For basic use such as web browsing or occasional movie watching, a smaller size and lower resolution are sufficient. For gaming monitors, opt for higher refresh rates and larger screens. For graphic designers and professionals, higher resolution and proper aspect ratio are crucial.
Panel Type
Image quality also depends on the display panel type. TN panels are the cheapest but also the least high-quality. They feature fast response times but weak color reproduction. On the other side are high-quality IPS or PLS panels, which provide realistic color rendering. VA panels can be a middle ground—better than TN but cheaper than IPS. Some offer high contrast, which can sometimes look unnatural.
Refresh Rate
A sufficiently high refresh rate ensures smooth image display. It indicates how many frames per second the monitor can render. The minimum refresh rate is around 60 Hz, which is sufficient for office work. However, for watching movies or gaming, at least 120 Hz is recommended. The most powerful monitors can reach up to 144 Hz.
Other Important Parameters
Do not overlook picture quality factors such as brightness or contrast. The display surface is also important. Glossy monitors provide richer colors but are harder to read in direct sunlight. Matte displays reduce glare but slightly mute colors. Connectivity is also key—the monitor should be compatible with your computer or laptop. HDMI and DisplayPort are most commonly used today, while older models may still use DVI or VGA. Always check which connector your computer requires.
Additional Features
Some monitors come with special features. Larger models may be curved, providing a better field of view. Useful functions include blue light reduction, built-in cameras, integrated speakers, or adjustable height and tilt.
Brand
Brand is also an important factor when choosing a monitor. Among the best-selling are HP and MSI monitors, but Acer and Samsung are equally popular.
If you don’t have a monitor but want to project images from your computer or another external source, you can use a projector. The image can be projected onto a screen or even a regular wall. The first thing you should decide is what you need the projector for.
There are several types of projectors:
Office Projectors
These are mainly used in offices and meeting rooms. They are designed for presentations and displaying text documents. They have higher brightness, making them suitable for daytime use. However, they feature lower contrast and resolution, making them less suitable for long movie screenings. On the other hand, they are more affordable.
Movie Projectors
These are designed mainly for watching movies or playing games. They provide higher resolution, better contrast, and superior color reproduction. They usually have lower brightness since they are intended for use in dark rooms or in the evening. High-resolution models can be significantly more expensive. These projectors are not suitable for presentations.
3D Projectors
If you want a cinema-like experience, a 3D projector can provide it. It can project both 2D and 3D images, and the glasses should be included in the package. These are suitable not only for movies but also for gaming—the experience is entirely different.
When choosing a projector, mounting options may also be important. You can place the projector on a table or mount it on the ceiling. Besides purpose, you may also consider features such as quiet mode, which reduces fan speed so the noise doesn’t disturb you. Remote control and built-in speakers are also practical features.
