A:Answer This monitor is 4K--that is, it displays 3840 pixels × 2160 lines or 8.3 megapixels. If you don't "need" that resolution then your run-of-the-mill HD monitor, which is 1,920 x 1080 or about 2.1 megapixels, will suffice. The $150 you're referring to--at least as of today's date of 11/29/17--is likely a "budget" HD monitor with very few bells and whistles. It's also worth noting that this Dell 2415Q monitor is an IPS panel with a wide color gamut that's important for discerning photographers, professional and otherwise. This, like many things in life, is an example of you get what you pay for. Ultimately, you'll have to decide what's important to you and your computing needs.
