Do you need a 4K monitor for photo editing? Well, no. You do not need a 4K monitor for photo editing. You can do some pretty decent photo editing work with a 2K (2560 x 1440) resolution if your monitor is over 27 inches wide.
Further, a full HD (1920 x 1080) resolution should be sufficient if you have a smaller monitor. So, you may not necessarily need a 4K monitor, but if you can get one, it will certainly upgrade the quality of your photo editing.
This upgrade will not come cheaply as 4K monitors are often more expensive, but with good reason. However, if this upgrade proves too costly, you could get a good quality budget monitor, and you will be fine.
However, if you are willing to spend a little extra cash, a 4K monitor for photo editing would be worth your while.
Pros of 4K Monitors for Photo Editing
Larger Screen Sizes
For creatives such as photo and video editors, a widescreen monitor can be invaluable in enhancing their efficiency. A wider screen increases productivity by offering more workspace since you can open several tabs. This alone makes multitasking easy. In some cases, a wide enough screen can eliminate the need for multi-monitor setups.
Larger screens also allow you to see and alter minute details as your images will be larger and easier to see, given the right resolution.
It is important to match screen sizes and resolutions. This is because you need an optimum amount of pixels per inch (PPI) to give you the image clarity you need. If the screen size vastly exceeds its resolution, you end up with pixelated images due to low pixel density (PPI).
Alternatively, a high resolution on a small screen will give you tiny, hard-to-edit images.
A 4K resolution (3840 x 2160) monitor will give you impressive image clarity, especially on widescreen monitors. You could get a 27-inch 4K photo editing monitor, which will give you an impressive 163 PPI pixel density. However, a wider 32-inch monitor will be perfect as it gives you a high 150 PPI pixel density plus additional workspace.
Eye Health
The next time you ask yourself, “Do I need a 4K monitor for photo editing?” you need to consider the health of your eyes. Photo editing work is time-intensive by nature, requiring one to spend multiple hours in front of a monitor.
Research has shown that individuals that spent more than 30 hours each week working on a computer were likely to develop computer vision syndrome (CVS). CVS is characterized by irritated, burning, red, strained, tired eyes, and blurred and double vision.
Since long photo editing hours are unavoidable, one way to mitigate the incidence of CVS is to improve your monitor’s resolution. Higher resolutions, coupled with the right screen size, make images clearer and more comfortable to view, thereby reducing eye strain.
Granted, your present eye health and distance from the monitor will decide how comfortably you can view images. A higher resolution will certainly improve that comfort. As such, a 4K monitor is the best as it minimizes eye strain to a greater degree.

Con of 4K Resolution and Multiple Functions
Multifunctionality is a desirable quality for modern technology, true for monitors. Consequently, people will go looking for the best monitor for programming and gaming as you get two computer monitors for the price of one. Such dual functionality saves money, as one need not purchase two monitors for each purpose. It also saves time as one wouldn’t have to switch monitors to do either task.
Sadly, when looking for the best monitor for photo editing and gaming, 4K monitors may not feature greatly. While 4K monitors are wonderful for photo editing, it requires more time and money to use them for gaming. You will need to find a 4K monitor with adaptive sync technologies such as AMD’s Free Sync that ensure a seamless experience. These are usually more expensive, and in their absence, you may have to purchase these technologies.
You will also need a high-quality graphics card to work with the adaptive sync technologies for a smooth gaming experience, which is also expensive. Further, your monitor will require a high refresh rate and have all the necessary ports and cables for gaming.
Overall, turning a 4K monitor into a gaming monitor is quite an expensive venture. You would do better to spend less money on a 2K (2560 x 1440) resolution monitor with a high refresh rate.
Cost
4K resolution monitors are generally more costly than those of lower resolutions. Granted, they are among the best PC monitors for photo editing giving excellent quality work. However, if you want a photo editing monitor for around $300, it definitely will not be a 4K monitor.
Additionally, 4K resolution works best for monitors measuring above 27 inches, so smaller and more affordable monitors will not be 4K. So for amateur photo editors who are just starting, the cost of a 4K monitor may be prohibitive.
The bottom line is that you do not need a 4K monitor for photo editing. While there are undeniable benefits to a 4K monitor for photo editing, you must consider the cost implications.
A lower resolution can do a decent photo editing job at a more affordable cost with the right monitor size, panel type, and contrast ratio. However, if you want the quality and efficiency that only a 4K monitor can bring, be prepared to spend a little more money.
