Twenty-seven inches is the most popular size for PC gaming. It is big enough to fill your view at a normal desk distance but small enough that you can still see the whole screen without turning your head. It also pairs well with 2560 x 1440 (1440p), which looks noticeably sharper than 1080p at this size.
When choosing, two specs matter most. The first is resolution versus refresh rate: 1440p at 180Hz to 220Hz suits most players, while 1080p at 240Hz favors fast competitive games on a midrange PC. The second is ports. You need to know which input actually delivers the top refresh rate on your setup.
How we chose
- Size and resolution: 27-inch screens at 1440p or 1080p, as stated in the listing.
- Refresh rate and response time: at least 180Hz, with listed response times and variable refresh support (FreeSync, G-Sync or Adaptive-Sync).
- Panel type: Fast IPS where stated, for color and viewing angles.
- Ports: which inputs are listed and which one carries the highest refresh rate.
- Stand and mounting: height, tilt and pivot adjustment and VESA support where listed.
Picks are based on manufacturer specs and owner reviews, not hands-on testing. Read how we research products for details.

The picks in detail
ASUS ROG XG27ACS
The XG27ACS hits the most popular target for 27-inch gaming: 2560 x 1440 at 180Hz. ASUS lists a Fast IPS panel with a 1ms (GTG) response time. ELMB Sync lets you run motion blur reduction and variable refresh at the same time, which the listing says cuts ghosting and tearing. The title lists G-SYNC compatibility and HDR. A USB-C port carries a DisplayPort signal and works as a USB hub, so a compatible laptop can connect with one cable. DisplayWidget Center lets you change settings with a mouse instead of the buttons.
Good fit if you want a balanced 1440p gaming screen that also works with a USB-C laptop.
Skip it if you need to know the stand’s range up front. The listing does not state it.
Samsung Odyssey G5 (G51F)
Samsung’s G51F matches the ASUS on paper at 2560 x 1440, 180Hz and 1ms. It adds HDR10 and AMD FreeSync. Black Equalizer brightens dark areas so enemies in shadows are easier to spot. The stand is the standout. It tilts, pivots and adjusts in height, which most budget gaming monitors skip. That makes it easier to set the screen at eye level without a separate arm.
Good fit if you want a 1440p gaming monitor with a proper adjustable stand out of the box.
Skip it if you need confirmed panel type or port details. Neither is stated in the listing, so check the spec sheet.
KTC H27T22C
The H27T22C gives you the highest 1440p refresh rate on this page for the lowest price tier. KTC lists up to 220Hz over DisplayPort 1.4. The listing also notes the panel was originally rated 200Hz. Over HDMI 2.0 it tops out at 144Hz. The Fast IPS panel claims 131% sRGB, 1.07 billion colors, HDR 400, 450 cd/m² brightness and a 1000:1 static contrast ratio. It supports FreeSync and G-Sync, has built-in speakers and a 100 x 100mm VESA pattern. KTC lists a three-year warranty.
Good fit if you want high-refresh 1440p for less and will connect over DisplayPort.
Skip it if you plan to use HDMI only. You will be capped at 144Hz.
KTC H27T6
This KTC is a white 1440p model with a native 200Hz refresh rate that can be overclocked to 210Hz. It uses a Fast IPS panel with a 1ms (MPRT) response time. KTC claims 450 cd/m² brightness, HDR400, 101% DCI-P3, 131% sRGB and Delta E under 2. That makes it a reasonable pick if you also edit photos or video. Two 2W speakers are built in. Ports are one DisplayPort 1.4 and two HDMI 2.0, so a PC and a console can stay plugged in. The stand tilts from -5 to 15 degrees, and there is a 100 x 100mm VESA mount.
Good fit if you want a white setup and care about color as well as speed.
Skip it if you need height adjustment without buying an arm.
KTC H27F7
The H27F7 trades resolution for speed. It is a 27-inch 1920 x 1080 Fast IPS panel at 240Hz with a 1ms (MPRT) response time. A midrange graphics card can reach high frame rates at 1080p much more easily than at 1440p. KTC also lists HDR10, 350 cd/m², 97% DCI-P3 and Delta E under 2. The stand adjusts for height, pivot and tilt, and it supports VESA mounting. Ports are two HDMI 2.0, one DisplayPort 1.4 and one USB 2.0.
Good fit if you play fast shooters and your PC cannot hold high frame rates at 1440p.
Skip it if you also read or work on this screen a lot. 1080p at 27 inches looks softer than 1440p.
How to choose a 27-inch gaming monitor
1440p or 1080p
For most people, 1440p is the right resolution at 27 inches. Text and game detail look much cleaner. Pick 1080p only if you play competitive titles and your graphics card cannot keep frame rates high at 1440p. If you are on a tight budget, our guide to monitors under $200 covers more 1080p options.
How much refresh rate you need
Going from 60Hz to 144Hz is the biggest jump most players notice. Moving from 144Hz to 180Hz or 240Hz is a smaller step and only helps when your PC actually produces that many frames. Our 144Hz monitor guide covers the entry point for smooth gaming.
Response time claims
“1ms” appears on almost every gaming listing, but makers measure it in different ways. GTG (gray to gray) and MPRT (moving picture response time) are not the same test. Treat these numbers as rough guides rather than direct comparisons.
Panel type
Fast IPS panels aim to combine IPS color and viewing angles with quicker pixel response. Four of the five picks list Fast IPS. Samsung’s listing for the G51F does not state the panel type.
Stand and setup
The top of the screen should sit around eye level. If a monitor only tilts, plan on a VESA arm. The Samsung G51F and KTC H27F7 list height adjustment in the box.
For larger or ultrawide options, see our broader gaming monitor picks.
Before you buy
- Check your graphics card’s outputs. To reach 200Hz or more at 1440p, you will usually need DisplayPort. The KTC H27T22C, for example, lists 144Hz max over HDMI 2.0.
- Console players: HDMI 2.0 ports generally limit consoles to lower refresh rates at 1440p. Check your console’s supported modes.
- Turn on the high refresh rate. Windows often defaults to 60Hz. Set the refresh rate in display settings after connecting.
- Overclock modes are optional. Listings that quote an “OC” refresh rate usually require turning it on in the monitor menu.
- Confirm the exact model. KTC sells several similar 27-inch models with different refresh rates and resolutions.
FAQ
Is 27 inches too big for competitive gaming?
Not for most players. Some esports players prefer 24 inches so the whole screen sits in central vision. At 27 inches, sitting a little farther back helps.
Do I need G-Sync or FreeSync?
Variable refresh reduces tearing when frame rates jump around. All five picks list some form of it: FreeSync, G-Sync compatibility or Adaptive-Sync.
Can these monitors be used for work too?
Yes. The 1440p models are good for documents and spreadsheets. The ASUS adds USB-C for a single-cable laptop connection.
Is HDR worth it on these monitors?
Entry-level HDR labels like HDR10 and HDR400 add some contrast to supported content. Do not expect the effect of high-end OLED or mini-LED screens.
