Lenovo Legion Y25-25
IPS and 240Hz for a price you can afford

It’s only 1080p, but Lenovo’s new 25-incher packs a 240Hz IPS punch.
BIG PANEL SIZE, huge pixel count, and epic refresh rate. Good luck getting all that in a single monitor for sensible money. On a realistic budget, something’s gotta give.
If you’re a gamer, that something is probably resolution. 4K is nice in theory; in practice, it’s a nightmare to drive all eight million pixels at remotely decent frame rates, let alone at truly high refresh rates well above 100Hz. You might also be willing to compromise on size, especially if a monitor delivers in other areas.
