The best gaming monitor for PS5 is the one whose HDMI port accepts what the console sends, 4K at 120Hz with HDMI Forum VRR. On RTINGS' current ranking that monitor is the MSI MPG 321URX, a 32-inch 4K QD-OLED. The panel is the easy part to judge. The port is where buyers get caught, because a monitor can say "HDMI 2.1" on the box and still not switch on the console's 120Hz mode.

This comes up at the checkout page. Best Buy's PS5 gaming monitor category lists 23 monitors, and its own FAQ says HDMI 2.1 is what enables 4K at 120Hz on PS5. Most of the individual listings on that page never say whether they have it.

For most buyers, the best gaming monitor at Best Buy this autumn is a 27-inch 1440p OLED for about $300. The IPS panels that used to sell at that price have dropped to around $210. Most of the picks below follow from that change.

Three outlets are tracking these prices. Tom's Guide has a roundup headlined up to $600 off LG and Samsung gaming monitors at Best Buy. PCWorld keeps reporting OLEDs under $300, and PC Gamer calls monitors the best value in PC gaming right now. The picks are grouped by price tier. Each price is the Best Buy price on the date the source read it. None of these monitors has a hub page yet, so each link goes to the listing or report that carried the price.

PC Gamer names the MSI MPG 321URX QD-OLED as the best 4K gaming monitor right now. At Best Buy prices read on October 26, 2026, though, the 32-inch Samsung Odyssey OLED G8 (G80SH) at $899.99 is the better buy if you want 4K, 240Hz and OLED at a price that is actually posted. Our sources don't give a current price for the MSI, and that gap matters more than any spec sheet.

The best 4K monitor depends on the price tier, and in late October the tiers moved. Below are the picks for each one, every price with its date, and a note on which prices still hold and which sales have ended.

The best 4K monitor for gaming right now is a 32-inch, 240Hz QD-OLED, and the one to buy is the MSI MPG 321URX if you can find it near its $949 launch price. The Alienware AW3225QF uses the same panel in a curved and usually pricier shell. Every monitor in this class uses one Samsung Display panel, so the choice comes down to price, curve, ports and how well each maker tunes it. The more expensive question is one the spec sheet leaves out: whether your graphics card can push anything close to 240 frames a second at 3840x2160.

On a gaming monitor box, "2K" means 1440p: a panel 1,440 pixels tall, almost always 2560x1440, which retailers also sell as QHD or WQHD. You will see the term on Best Buy listings and in deal roundups. It decides two things at once: how sharp a 27-inch screen looks, and how hard your graphics card has to work to fill it.

This month it settled a third question. A 1440p 240Hz OLED is no longer a premium purchase. Best Buy sold the AOC Q27G41ZDF for $300 during the October 6 to 7 Prime Big Deals window, PCWorld reported. On October 23, Tom's Hardware flagged the Acer Predator XB27OU QD-OLED at $329.99 there, down from $379.99. If you want the short answer to "best 2K monitor for gaming", it is one of those two panels. The rest of this piece explains why, and which card you need to drive it.

The affordable gaming monitor worth buying is the cheapest one your graphics card can actually use: a 27-inch 1440p panel at 165Hz to 180Hz for most current cards, and 1080p at 144Hz only if the GPU is truly entry-level. You'll run into this decision in every Best Buy deal listing, and it settles whether the extra $50 to $150 gets you a better picture or just a bigger number on the box.

The timing matters because the tier just shifted. Best Buy put the 27-inch AOC Q27G41ZDF QD-OLED (1440p, 240Hz) at $299.99, down from a $499.99 MSRP, which PC Gamer called "an absolute steal" and PCWorld reported at $300 on October 6, 2026. When OLED reaches $300, everything below it has to justify its price.

A 1440p, 240Hz QD-OLED gaming monitor now costs about what a decent IPS panel did, which makes OLED the best cheap gaming monitor for anyone spending around $300. Best Buy listed the Acer Predator XB270U at $329.99 in the week of October 21 to 23, 2026, and the AOC Q27G41ZDF sold there for $299.99.

The Acer deal was posted to Slickdeals on October 21, and Tom's Hardware confirmed it on October 23 as $50 off a $379.99 regular price. PC Gamer called the Acer "the cheapest OLED gaming monitor I'd actually buy". Its own deals desk also pointed to a cheaper option: the AOC, which it called "the cheapest OLED gaming monitor I'd recommend right now". Both outlets are crowning a cheapest OLED in the same month. That tells you more about where prices are heading than either headline does.

The cheapest gaming monitor worth buying is the cheapest one whose refresh rate your graphics card can fill and whose adaptive sync works. For anyone on an RTX 5060-class card, that currently means a 1080p IPS panel at about $100, not the discounted 1440p screens getting the headlines.

On Best Buy's under-$200 gaming monitor page, as read the week of October 23, 2026, the floor is the Acer 24KG1Y X3bip at $98.49: 1080p, 200Hz, IPS. That is the pick. The cheapest 1440p step on the same page is the GIGABYTE G27Q20 at $161.99 (200Hz, IPS), and it is the only QHD model the page lists under $200.
