Acer Nitro XV340CK PBMIIPPHZX | 34-inch | 3440 x 1440 | 144Hz | IPS | $299.99 $239.99 at Newegg (save $60)
An older model, but it checks out. The combination of 34-inch ultrawide, 3,440 by 1,440 resolution, 144Hz and an IPS panel is pretty sweet for just $240, especially the IPS bit. The catch? Well, it tops at 250 nits, which is adequate but no more. But it's still a very nice deal.View Deal
In terms of sensible-money monitors, the 34-inch ultrawide is out favourite form factor among all the best gaming monitors.
