Answer: For professional purposes and everyday use, 4K monitors are worth it since they've become very affordable lately. When it comes to PC gaming, we don't recommend them as the 4K UHD resolution is very demanding and the improvement in image quality over a good 1440p display is rarely worth the performance hit.

Is 4K too big?

Answer: The ideal size for a monitor mainly depends on its resolution and how far you're sitting from the screen. Overall, most people find that 1920×1080 shouldn't be used on anything larger than 25-inch; 1440p is ideal for 27-inch, and 4K is great for 27-inch to 43-inch, depending on preference.

Should I go 4K or not?

If you mostly watch livestreams or broadcast TV, there's not much point to 4K, since the majority of what you're seeing will be in 1080p or even smaller resolutions. If you specifically want a TV sized 40 inches or smaller, 4K probably won't be an option.
