Best 240Hz OLED Monitors for Competitive Esports Gaming
Competitive esports players care about three things a spec sheet actually proves: refresh rate, response time, and how consistently the panel keeps up when a match gets chaotic. OLED adds near-instant pixel response and deep contrast for spotting enemies in dark corners, which is why it has become the panel type serious players gravitate toward when they can afford it.
The products below split into two groups: true or near-240Hz OLED panels that match the query directly, and fast non-OLED alternatives for players who want competitive-grade refresh rates without OLED pricing. Size and shape matter too — a flat 27-inch panel keeps aim consistent in a way a large curved ultrawide doesn't, so that's factored into how these are ranked.
Each pick below is chosen for a specific type of competitive setup, not just overall polish.

LG 39GX90SA-W 39-inch Ultragear WQHD (3440 x 1440) OLED Curved Gaming Monitor 240Hz, 1ms, NVIDIA G-Sync Compatible, AMD FreeSync Premium, VESA DisplayHDR True Black 400, webOS, USB Type-C, White
This is the only panel in the lineup that actually hits the 240Hz OLED spec the query is asking for, with 1ms (0.03ms GtG) response and both G-Sync Compatible and FreeSync Premium support for tear-free competitive play.
- +240Hz refresh and 0.03ms response for fast-paced gaming
- +FreeSync Premium and G-Sync Compatible for tear-free play
- +DisplayHDR True Black 400 with 1.5M:1 contrast ratio
- −800R curve less practical for spreadsheet or coding work
- −WQHD resolution is less pixel-dense than a 4K ultrawide
LG 45GX950A-B 45-inch Ultragear 5K2K WUHD (5120 x 2160) OLED Curved Gaming Monitor, Dual-Mode, 165Hz, 0.03ms, NVIDIA G-Sync, AMD FreeSync Premium Pro, HDR True Black 400, USB Type-C 90W, DP2.1
Dual Mode drops resolution to push refresh rate to 330Hz, which beats standard 240Hz OLED options for players who prioritize raw speed over the highest resolution, with the same 0.03ms response time backing it up.
- +5120x2160 resolution with 125 PPI for sharp text and detail
- +Dual Mode switches to 330Hz at lower resolution
- +0.03ms GtG response time for minimal ghosting
- −Requires a high-end GPU to use full 5K2K resolution
- −OLED panels carry inherent burn-in risk with static content
Samsung 27” Odyssey OLED G5 (G50SF) Series QHD & QD-OLED Gaming Monitor
At 27 inches and flat QD-OLED, this keeps the consistent aiming geometry competitive players prefer over ultrawide curves, and its 0.03ms response time and 180Hz refresh still comfortably clear the threshold for fast-paced play.
- +180Hz refresh rate suited to fast-paced gaming
- +0.03ms response time reduces motion blur
- +QD-OLED panel with Pantone Validated color accuracy
- −QHD resolution, not 4K, at 27 inches
- −HDR10 only, no higher HDR tier listed
Samsung 32" Odyssey (G55C) Series QHD 1000R Curved Gaming Monitor, | 165Hz, 1ms(MPRT), HDR10, AMD Radeon FreeSync, Eye Care, Glare Free, Sharp Resolution (LS32CG550ENXZA)
For players who want a fast panel without OLED pricing, 165Hz and 1ms MPRT response cover most competitive titles, and buyers get FreeSync tear reduction without stepping up to a premium panel type.
- +165Hz refresh rate with 1ms MPRT for fast motion
- +QHD resolution sharper than 1080p at this size
- +1000R curve adds strong immersion for gaming
- −Aggressive curve can distort straight lines for productivity use
- −Glossy screen surface may reflect strong overhead light
Samsung 27" Odyssey G5 (G51F) Series QHD (1440P) Gaming Monitor
180Hz on a QHD panel gives sharper detail than 1080p competitive monitors while still hitting a refresh rate that matters for fast-paced shooters, making it a reasonable step-down pick for players not ready to commit to OLED.
- +180Hz refresh rate suits fast-paced competitive gaming
- +QHD resolution sharper than standard Full HD panels
- +AMD FreeSync reduces tearing and stutter
- −No color accuracy or gamut specs provided
- −No USB-C or speaker details listed
What to look for
Refresh rate and response time only matter together. A 240Hz panel with a slow response time still smears motion, which is why OLED's near-0.03ms GtG figures matter more for esports than the Hz number alone. When comparing spec sheets, check whether response time is listed as GtG or MPRT — they're not directly comparable, and MPRT numbers often look faster than they behave in practice.
Size and shape matter more than most buyers expect. A 27-inch flat panel keeps your crosshair placement consistent match to match; a large curved ultrawide changes edge distances and can throw off aim during flick shots, even if the refresh rate is higher. If you're buying OLED, also factor in burn-in risk from static HUD elements and crosshairs — it's a real tradeoff for the contrast and speed you gain, not a myth.
