An ultra-wide curved screen replaces two desktop monitors and handles work just as well as gaming. A solid one should easily last you five to seven years, so buying a cheap placeholder is usually a waste. Display tech moves on a yearly cycle, and last year's flagship panel often drops sharply in price right when the newest version arrives with only marginal upgrades.
If you time the purchase for November sales events, you can usually pick up a top-tier display for around $850. Spreading that cost out with the right zero-interest financing makes it painless, as long as you have a plan to clear the balance before the clock runs out.
Keep in mind that 0% interest is a strict deadline, not free money. If you still have a balance when the 18 months are up, standard interest rates kick in on whatever remains, which can quickly erase everything you saved on sale.
