For a puzzle‑oriented display I’d stick with a sharp native resolution—1080p is the sweet spot for most monitors, but if you have a larger screen, 1440p gives you more detail without the extra load. Aim for a refresh rate of 60 Hz or higher; 120 Hz or 144 Hz can help if you’re doing fast‑moving logic puzzles or speed‑solving. Color profile is less critical than clarity, but use a standard sRGB space. It’s the most consistent across displays and eliminates color shifts that can mask subtle differences in puzzle elements. If you’re using a monitor that supports a wider gamut and you need very accurate hues for a specific puzzle type (like a color‑matching game), you could switch to DCI‑P3 or Adobe RGB, but keep the gamma at 2.2 to avoid eye fatigue. In short: 1920×1080 or 2560×1440, 60–144 Hz, sRGB, 2.2 gamma. That’s the cleanest, most reliable foundation for precise visual work.
