The Best Cheap Gaming Monitor Is Now an OLED

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.

There was no single discount. There was a slide. Acer launched the Predator X27U X1, a 27-inch WQHD QD-OLED at 240Hz, at $599.99 in North America, according to TFTCentral's April 2025 report. The retail XB270U sits in the same panel family and carries a $379.99 list price. Since then it has come down in steps. PC Gamer's coverage describes a further $20 cut stacked on an earlier reduction, not a one-off flash sale.

The AOC followed the same pattern. According to PC Gamer, citing Slickdeals price history, it sold for $370 earlier in 2026 and $330 in August, then dropped to $299.99 against a $499.99 list price. Neither drop happened alone. Tom's Guide reports that Best Buy ran a multi-brand monitor sale in the same window, with discounts of up to $600 on LG and Samsung models.

The Acer costs $30 more than the AOC. For that money you get two HDMI 2.1 ports in place of one HDMI 2.0, which matters if a PS5 or Xbox Series X shares the desk, because HDMI 2.0 cannot carry 1440p at 120Hz-plus the way 2.1 can. You also get FreeSync Premium, which Best Buy's listing confirms. You give up half an inch of diagonal: the Acer is a 26.5-inch panel sold as a 27. On a PC-only desk the AOC has the better price per feature, and PC Gamer notes its feature set is barebones. AOC rates it at 200 nits standard and 400 nits peak.

The 0.03ms figure is a gray-to-gray rating from the manufacturer, quoted by Best Buy, Slickdeals and everyone downstream. It is not input lag, and it is not a measurement anyone in these sources took. Checking it would take an independent review with a pursuit camera and a latency rig. TFTCentral, the outlet most likely to run one, has no review of the XB270U. Its only coverage is the X27U X1 announcement, which lists 250 nits SDR, 1000 nits peak HDR at 3% APL and DisplayHDR 400 True Black. Those are vendor figures for a sibling model. Whether the cheaper retail SKU matches them is not yet known.

The $329.99 is also a sale price, not a new MSRP. On the evidence of the AOC's history it could fall again, or it could go back to $379.99 when the sale ends. The sources do not say which.

A 240Hz OLED only pays off if the GPU can feed it. In demanding games it usually cannot, and that is fine, because OLED's contrast and pixel response still help at lower frame rates. In Cyberpunk 2077 at 1440p Ultra, Tom's Hardware measured the GeForce RTX 5060 at 42.1 fps (GPU hierarchy, June 24, 2026). It measured the Radeon RX 9070 XT at 81.8 fps in its RX 9070 GRE review (June 2, 2026). These come from separate test runs, and neither card is near 240 in that game. Esports titles are a different matter. In its Core Ultra 7 270K Plus review on March 23, 2026, Tom's Hardware recorded 524 fps in Counter-Strike 2 at 1080p Ultra with the Core Ultra 5 245K.

So the split is this. If you play esports at 1080p and your budget stops well short of $300, a fast 1080p LCD still covers the job. We priced that tier at this week's cheapest monitors, and this week's sources do not give updated LCD prices. If you play a mix of games at 1440p, $299.99 to $329.99 now buys a QD-OLED. A cheaper 1440p LCD gives up contrast and motion clarity to save very little. For that buyer, the cheap monitor is now an OLED.

If you only have a PC, take the AOC at $299.99. If a console shares the screen, take the Acer at $329.99 for the HDMI 2.1 ports. Check Best Buy's listing on the day you buy, because both prices were read in late October 2026 and both have moved before. Then work out what your GPU actually delivers at 1440p, because that decides how much of the 240Hz you will ever see. The 1440p price-per-frame ranking is where that answer lives.
