Best gaming monitor (2026): the resolution, refresh, and panels I would actually buy

Not sure which gaming monitor to buy? For most people, the answer is a 27-inch 1440p panel with a refresh rate your PC can fill, which in 2026 usually means 240 Hz. Two official LG models cover the split: the UltraGear 27GR83Q-B (IPS, 1 ms GtG, 240 Hz, HDMI 2.1 ×2 + DisplayPort, $499.99 on LG US) and the 27GS93QE-B (OLED, 0.03 ms, 240 Hz, HDR True Black 400, $899.99 on LG US). I don’t own either. I play on two 27-inch screens: a 1080p 240 Hz and a 1440p 155 Hz, driven by an RTX 5080 16 GB.

Keep in mind that 240 Hz only matters if your card can draw the frames. If you already own a 155–165 Hz 1440p panel, it isn’t automatically obsolete.

Quick picks

• IPS 27” 1440p 240 Hz to open first: LG UltraGear 27GR83Q-B. Official: 2560×1440 IPS, 1 ms GtG, 240 Hz, DCI-P3 95% (typ.), VESA DisplayHDR 400, G-SYNC Compatible, FreeSync Premium, HDMI 2.1 ×2, DisplayPort, height / tilt / pivot. LG US $499.99. LG US page. Amazon search for 27GR83Q-B
• OLED 27” 1440p 240 Hz: LG 27GS93QE-B. Official: 27” OLED, 1440p, 240 Hz, 0.03 ms, DisplayHDR True Black 400, 1.5M:1 contrast (LG), G-SYNC Compatible, FreeSync Premium Pro. LG US $899.99. LG US page. Amazon search for 27GS93QE-B
• What I actually use: two 27-inch monitors, one 1080p 240 Hz and one 1440p 155 Hz, driven by an RTX 5080. 1440p is sharp, and the card can still feed a high refresh rate.

The short version: resolution your GPU can hold, size your desk can hold, Hertz you will actually see. More monitor guides.

Comparison table

LG notes on the 27GS93QE-B: a graphics card with DisplayPort 1.4 or HDMI 2.1 is required to reach 240 Hz.

Pick resolution first

The PC draws the pixels. A monitor cannot invent them.

• 1080p — still the competitive default when you want 240 Hz from a mid-range card, or when you sit close at 24–25 inches. FPS monitor notes.
• 1440p — the 2026 all-rounder at 27 inches. Text is readable. An RTX 5080 has an easy time here; that is why I play at 1440p rather than on a 4K screen.
• 4K — when 4K is worth it is its own page. It wants HDMI 2.1 or DisplayPort 1.4 on both ends if you want more than 60 Hz.

NVIDIA’s official RTX 5080 page lists display support up to 4K at 480 Hz or 8K at 165 Hz with DSC, 3× DisplayPort + 1× HDMI. That is headroom. It is not a reason to buy a 4K 240 Hz OLED before you have filled 1440p.

Then pick Hertz

Refresh rate is how many new pictures the panel can draw in a second. The card has to produce them.

• 144–165 Hz is the floor I would still buy in 2026 for a first gaming monitor. My own screens are both 27-inch: a 1080p 240 Hz and a 1440p 155 Hz. They’re plenty for story games and WoW.
• 240 Hz is the step that shows up when the card is already making 200+ frames. 1440p 240 Hz is the same idea with a richer image and a hungrier GPU.
• 360 Hz and up exist. See 360 Hz. Buy it after you can tell 240 from 165 on your own machine.

A 240 Hz monitor on a PC that holds 80 fps still shows about 80. The unused headroom is a label.

The Hertz on the box has to be the Hertz at the resolution you will use, on the port you will plug in. Some panels print a high number that only exists at 1080p, or only on DisplayPort.

IPS or OLED

I haven’t tested either LG myself, but here’s the official split:

27GR83Q-B (IPS) — 1 ms GtG, DisplayHDR 400, 95% DCI-P3 (typ.), two HDMI 2.1 ports, $499.99 on LG US. Cheaper class, useful if the desk gets bright or you leave static UI up for hours (Discord, a WoW map).

27GS93QE-B (OLED) — 0.03 ms, True Black 400, 1.5M:1 contrast (LG), $899.99 on LG US. This is the contrast answer in 27-inch 1440p. Read the burn-in warranty before you pay OLED money.

A curve does not add pixels or Hertz. When a curve helps is a wide screen you sit close to. A 27-inch 16:9 panel is simpler flat. IPS vs VA if you are still on an older LCD.

What I actually sit in front of

My setup is two 27-inch monitors (1080p 240 Hz and 1440p 155 Hz) with an RTX 5080 16 GB and an AMD Ryzen 9 9950X3D2. 1440p gives me sharp text and smooth Zarya tracking without the 4K performance cost.

The decision rule is the useful part: competitive on the faster, lower-res panel; everything else on the sharper one.

The mouse on my setup is a Logitech PRO 2 LIGHTSPEED at 1200 DPI. The monitor does not fix a bad sensitivity.

Desk, ports, and VRR

• Depth: monitor desk size. A 27-inch 1440p panel wants roughly an arm’s length. Mounting is on the monitor arm page.
• Ports: HDMI 2.1 or DisplayPort 1.4 (or better) on both the monitor and the card when you want 1440p 240 Hz or 4K above 60 Hz. LG is explicit about that on the OLED.
• VRR / G-SYNC: turn it on after resolution and Hertz. It hides the leftover tearing. It does not add frames.

Who should stay on 155 Hz (or 144)

I already own two 27-inch monitors: 1080p 240 Hz and 1440p 155 Hz. Reasons I would tell you to wait:

• The card does not hold 200+ frames in the games you play at that resolution
• The desk is bright and you leave a static UI up for hours (OLED care)
• The panel you have is already 27-inch 1440p and the stand/arm works
• You would be paying for Hertz you will see in the menu, not in the fight

Get 240 Hz first if you play competitive shooters. Upgrade to 27-inch 1440p 240 Hz IPS (27GR83Q-B class) when the 5080-class card is already making those frames at 1440p. Upgrade to OLED when you want the contrast and you have read the warranty.

Input lag, response time, and motion-blur reduction are their own pages. Maker 1 ms / 0.03 ms numbers are the starting filter, not a lab report.

HDR, brightness, and the bright-room test

LG prints DisplayHDR 400 on the IPS and True Black 400 on the OLED. Those are VESA / HDR labels, not a promise that the room disappears. If the desk faces a window, IPS at 400-class HDR is often the more usable daytime panel. OLED’s black is the night feature.

If the listing will not print a brightness number, do not buy it for HDR. Monitor HDR.

Dual-monitor layout on my setup

Play panel centered. Second panel off-axis, same height if you can arm it. Mixed Hertz is fine; Windows will handle it. Mixed scale (100% vs 125%) is the annoying part — set each panel’s scaling so text matches, then leave it.

The mouse stays on the 1080p side because that is the aim screen. A second panel is not a reason to buy an ultrawide. Ultrawide vs 16:9 if you are tempted.

What the listing has to print

• Exact model (27GR83Q-B, not “27-inch UltraGear”)
• Resolution and the Hertz at that resolution
• Panel type (IPS, VA, OLED / QD-OLED)
• Ports, with the Hertz each port can do
• Stand adjust (height at minimum) or VESA size if you will arm it
• Today’s price. The LG US numbers above were current on 23 October 2026. Confirm the live page.

Then go back to the PC. A $1,000 240 Hz monitor is wasted if your PC only makes 90 FPS.

Common questions

What is the best gaming monitor in 2026?

For most people, a 27-inch 1440p 240 Hz monitor. The LG UltraGear 27GR83Q-B is a solid IPS pick, and the LG 27GS93QE-B is the OLED upgrade with deeper blacks and faster response.

What refresh rate should a gaming monitor have?

144 Hz is the minimum for competitive play, and 240 Hz is worth it if your PC can push that many frames. Buy a refresh rate your PC can actually reach at the resolution you play.

Is 4K the best resolution for a gaming monitor?

Not for most players. 4K looks great in story games but costs a lot of FPS, so 1440p at a high refresh rate is the better choice for competitive games.

What size gaming monitor should I get?

27 inches for 1440p, 24 to 25 inches for 1080p, and about 32 inches for 4K. Those sizes keep text readable and the image sharp at a normal desk distance.

Is an OLED gaming monitor worth it?

Yes, if you want the best contrast and motion clarity and your room isn't very bright. Check the burn-in warranty; if you leave static windows up for hours, a 240 Hz IPS is the cheaper, worry-free option.

Do I need G-SYNC or FreeSync?

You need variable refresh that works with your graphics card. Most monitors support both G-SYNC Compatible and FreeSync, so just turn it on once your resolution and refresh rate are set.
