I recently built a budget AM4 system with a GTX 1060 for light gaming. My old 24-inch Dell UltraSharp monitor developed a fault and died, so I tried replacing it with a 27-inch UltraGear display. It looked noticeably blurry, and I later realized that 1080p stretched across 27 inches has relatively low pixel density. I returned it and tried a 25-inch 1080p AOC monitor, but its brightness was excessive even at the lowest setting and it had very noticeable backlight bleed, so that one did not work out either.
I prefer a 27-inch display because 24–25 inches feels cramped for browsing, reading, YouTube, and general everyday use. However, I am unsure whether to choose 1080p, 1440p, or 4K. My GTX 1060 would probably struggle with higher resolutions in games right now, but I am hoping to upgrade the rest of the system over the next year. Since monitors tend to last longer than PC components, I would like to buy something that will still make sense after a future upgrade.
Would a 27-inch 1440p monitor be a reasonable choice if I temporarily run games at lower settings, or would 4K be more flexible? If I use a 4K display at 1080p for gaming, will it look acceptable, or will the image become blurry or blocky? I would appreciate advice based on a mix of light gaming and mostly desktop, reading, video, and web use.

Some 4K monitors support a special high-refresh dual-resolution mode, but regular 4K-to-1080p switching is not a replacement for having a native 1080p panel. It can be usable for games, yet it will not look as refined as a properly sized 1080p display. For this setup, 27-inch 1440p is the sensible future-oriented choice, while 24-inch 1080p is the sensible current-hardware choice.
For your current graphics card, 24 inches at 1080p is the safest match for gaming. A GTX 1060 generally is not powerful enough for modern games at 1440p or 4K, especially if you want high frame rates. Pixel density is a balance between physical size and resolution: 24-inch 1080p and 27-inch 1440p are common pairings because they look reasonably sharp.
