Yes, you can use a gaming monitor for photo editing, but it may not always be ideal. Gaming monitors often have fast refresh rates and high resolution, which are great for gaming but might not provide the best color accuracy, which is crucial for photo editing.
For professional-grade photo editing, it’s better to use a monitor designed specifically for color-critical work, such as those with an IPS panel and wide color gamut.
However, if your gaming monitor offers good color accuracy and covers a wide color range (like AdobeRGB or DCI-P3), it can be a viable option for editing.
