Best Budget Gaming Monitors Under $400 in 2026
Quick answer: with $400 to spend, buy a 27-inch 1440p monitor — the MSI G274QPF E2 ($190-$280) or LG UltraGear 27GS75Q-B ($170-$200) — unless you play competitive shooters for a living, in which case the 24-inch 1080p picks at 180-220Hz below cost half as much and are easier for your GPU to feed. Nothing on this list needs the full $400; the budget class is that good in 2026.

The 1080p esports picks — 24-25 inch
AOC 24G4 — successor to a legend
23.8" Fast IPS · 1920x1080 · 180Hz over both DP and HDMI · 1ms GtG / 0.5ms MPRT (marketed) · Adaptive-Sync, G-Sync Compatible on units made from June 2024 · HDR10 support only · 1x HDMI 2.0, 1x DisplayPort 1.4 · $110-$180
The 24G2 was the budget recommendation for years; the 24G4 is its proper successor with a faster 180Hz panel. One buying trap, from AOC's own datasheet: G-Sync Compatible and the 0.5ms MPRT version arrived in a mid-2024 revision, so check the manufacture date on suspiciously cheap old stock.
ASUS TUF Gaming VG249Q3A — the safe-brand pick
23.8" Fast IPS · 1920x1080 · 180Hz · 1ms GtG (marketed) with ELMB strobing · $110-$150
ASUS's entry gaming panel does everything the class requires — 180Hz, fast IPS, low-motion-blur strobing — with big-brand warranty and availability behind it. The sensible buy when the AOC is out of stock or priced at the top of its range.
BenQ MOBIUZ EX251 — the fastest cheap panel here
24.5" IPS · 1920x1080 · 220Hz · $100-$150
The replacement for the discontinued EX2510S pushes to 220Hz at 1080p — the highest refresh on this page at the lowest typical price. The 24.5-inch size is the current esports standard, giving a small sharpness edge over 23.8-inch panels at the same resolution.
The 1440p picks — 27 inch, the sweet spot
Dell G2724D — often the cheapest 1440p worth buying
27" Fast IPS · 2560x1440 · 165Hz over DisplayPort, 144Hz over HDMI · $150-$300
Dell's budget 1440p panel is a review-site staple that regularly discounts to near 1080p money. Two cautions from our November 2026 checks: stock is intermittent at Dell, and the honest price is the bottom half of that range — a price near $300 is a third-party marketplace markup, so wait for Dell or a major retailer to restock.
LG UltraGear 27GS75Q-B — 180Hz with a 200Hz overclock
27" IPS · 2560x1440 · 180Hz, 200Hz overclock · $170-$200
The sharpest value in the 1440p group: proper 180Hz out of the box with a 200Hz overclock if your card can push it, at a consistently low street price. Check the exact suffix before checkout — 27GS75Q-B and 27GS75QX-B are different listings with different details.
MSI G274QPF E2 — the one to buy with the full budget
27" Rapid IPS · 2560x1440 · 180Hz · $190-$280
The E2 revision (not the older G274QPF — check the suffix) is the most complete package here and the natural ceiling of a $400 budget: you will still come in well under it. Buy this if the monitor must serve gaming and desktop work for years; buy the LG if the same specs at less money matter more.
Buying notes for November 2026
Use DisplayPort for the headline refresh rate on every 1440p pick — HDMI tops out lower on the Dell and MSI, and the LG's overclock is DP-only.
HDR on this whole list is entry-level. HDR10 acceptance and DisplayHDR 400 mean the monitor can show an HDR signal at about 400 nits; none of these has local dimming, so buy them for refresh rate and resolution, not HDR.
The "1ms" on the box is a best-case figure at maximum overdrive. Real average response for fast IPS in this class is several milliseconds in independent testing — still fast enough that you will not be the reason you lost.
A price far above the range is a markup, not a shortage. Monitor prices move weekly in November; if a pick is listed well above its range by a marketplace seller, wait for the manufacturer or a major retailer.
Frequently asked questions
1080p or 1440p for budget gaming?
If your GPU is a mid-range card and you play competitive shooters, 1080p at 180-220Hz (picks 1-3) will feel faster and cost less. For everything else — story games, mixed gaming and desktop work — 27-inch 1440p (picks 4-6) is visibly sharper at about 109 ppi and is the better long-term buy.
Do I need G-Sync or FreeSync at this price?
Every pick here supports adaptive sync, which is what matters: it stops tearing without the input lag of V-Sync. Whether the box says FreeSync, Adaptive-Sync or G-Sync Compatible, all modern AMD and NVIDIA cards can use it over DisplayPort.
Is $400 enough for a monitor that lasts?
Yes — in 2026 the $170-$280 band buys 1440p, 180Hz and a good IPS panel, which was flagship money five years ago. Spend the change on a monitor arm or a better GPU before spending it on a pricier monitor in this class.
