KTC 27-inch Gaming Monitor Review 2024

Average monitor lifespan is 50,000 hours. That’s roughly 17 hours daily for 8 years. Choose poorly and you’re looking at 8 years of colour inaccuracy, ghosting in competitive titles, or eye strain from inadequate brightness control. The numbers matter here.

The 1500R curve is aggressive. More so than the common 1800R you’ll find on most curved displays. KTC’s aiming for immersion here, and it works if you’re sitting dead centre. Move 30 degrees off-axis and the curve starts working against you, distorting straight lines in productivity applications. For gaming? Brilliant. For Excel spreadsheets? Less so.

I measured 2847:1 contrast ratio after calibration. That’s proper VA territory and miles ahead of the 1000:1 you’d get from a budget IPS. In practice, this means dark scenes in games like Resident Evil 4 Remake or Alan Wake 2 maintain shadow detail without the grey wash you’d see on cheaper panels. Blacks look black, not dark grey.

But here’s where VA panels stumble: pixel transition times. Even the fastest VA panels can’t match IPS for grey-to-grey transitions, and this is a budget VA panel. You’ll see trailing in high-contrast scenarios, particularly noticeable when panning across bright objects against dark backgrounds.

The “1ms” claim is pure marketing fantasy. Real-world measurements with a pursuit camera show 6-8ms average grey-to-grey transitions, which is acceptable for a budget VA but nowhere near the sub-4ms you’d get from a Fast IPS panel. In Apex Legends and CS2, I noticed trailing behind fast-moving players, though it’s not severe enough to ruin competitive play if you’re not at the highest skill brackets.

Let’s be clear about that 1ms claim: it’s rubbish. Every manufacturer does this, measuring the absolute fastest transition (usually black to white) under unrealistic conditions. What matters is average grey-to-grey response time across the full range of pixel transitions.

I measured 6-8ms average with the overdrive set to Medium. That’s the sweet spot. Push it to the highest setting and you’ll introduce inverse ghosting (bright coronas trailing moving objects), which looks worse than the smearing you’re trying to eliminate. Leave it on Low and dark transitions become noticeably sluggish.

Input lag measured 4.2ms at 165Hz, which is excellent. There’s no perceptible delay between mouse movement and on-screen response. Combined with the high refresh rate, the monitor feels responsive even if pixel transitions aren’t the fastest.

The HDR implementation is utterly pointless. At 267 nits peak brightness with no local dimming, enabling HDR just crushes shadow detail and makes everything look washed out. Real HDR requires at least 400 nits sustained brightness and preferably 600+ nits peak with local dimming zones. This has neither. Keep HDR disabled and stick to SDR content.

Colour accuracy is where budget monitors typically stumble, and the KTC is no exception. That Delta E of 3.8 out of the box means colours are noticeably off if you’re used to calibrated displays. Reds skew orange, blues lean cyan, and the overall gamma curve is too aggressive, crushing shadow detail.

I spent an hour with my X-Rite i1Display Pro and got things looking respectable. Delta E dropped to 1.9, gamma flattened to a proper 2.2 curve, and colour temperature hit 6504K (near-perfect for D65). But here’s the thing: most buyers at this price point won’t have a £200 colorimeter lying about. You’re stuck with the out-of-box colours unless you’re willing to invest in calibration hardware.

Three weeks of testing across multiple genres revealed the KTC’s strengths and weaknesses. In Apex Legends running at 165fps (RTX 4060, low settings), the high refresh rate delivered smooth tracking and responsive aiming. The VA smearing was noticeable when spinning quickly, but the 4.2ms input lag meant my inputs registered instantly.

CS2 at 165fps felt excellent. The lower input lag compared to 60Hz or even 144Hz monitors is tangible. Flick shots registered accurately, and peeking corners felt responsive. The ghosting became apparent when tracking fast-moving opponents across high-contrast backgrounds (light player models against dark walls), but it wasn’t severe enough to impact my performance meaningfully.

Where this monitor truly excels is atmospheric single-player games. Resident Evil 4 Remake looked stunning. The 2847:1 contrast ratio meant dark corridors maintained shadow detail without the grey wash you’d get from IPS panels. I could spot enemies lurking in shadows without cranking brightness to uncomfortable levels.

Cyberpunk 2077’s Night City benefited from the contrast ratio as well. Neon signs popped against dark streets, and the overall image depth was impressive for a budget display. The curve enhanced immersion, wrapping the peripheral vision in a way that flat panels can’t match.

No height adjustment, no swivel, no pivot. Just tilt. And even that’s limited to a narrow -5° to 15° range. For a 27-inch display, this is problematic. You’ll need to stack books under the base or use a monitor arm to get the screen at proper eye level.

Connectivity is adequate. One DisplayPort 1.2 for 165Hz operation, two HDMI 2.0 ports for consoles or secondary PCs. The HDMI ports max out at 120Hz, which is fine for PS5 or Xbox Series X gaming at 1080p. No USB-C, no USB hub, no built-in speakers. You’re getting display connectivity only.

MSI’s G27C4 E2 sits between the two in price and performance. It offers 170Hz refresh (marginally higher than the KTC), similar VA panel quality, and slightly better build quality. The MSI also includes basic height adjustment. If you can find it on sale, it’s worth considering, but at full retail, the KTC undercuts it enough to remain compelling.

All three monitors suffer from the same fundamental limitation: 1080p at 27 inches means 82 PPI. If you want sharper text and better image clarity, you need to step up to 1440p, which pushes you into the £200-300 bracket with monitors like the Gigabyte M27Q or AOC Q27G2S.

Here’s the calculation: you’re getting 165Hz VA panel performance for roughly £130. The nearest equivalent from established brands costs £160-180. That £30-50 difference buys you better build quality, improved ergonomics, and potentially tighter quality control. But the core gaming experience – refresh rate, response time, input lag – remains similar.

Where the KTC makes sense is for gamers who’ll immediately mount it on a VESA arm (negating the poor stand) and who don’t need colour accuracy for professional work. If you’re playing competitive shooters, MOBAs, or fast-paced action games, the high refresh rate matters more than perfect sRGB coverage.

Where it doesn’t make sense: content creators, photographers, designers, or anyone who needs colour accuracy. The lack of factory calibration and sRGB clamp means you’re starting from a poor baseline. Spending an extra £50-70 on an IPS monitor with better out-of-box colour accuracy will save you frustration.

The 165Hz refresh rate and low input lag deliver a responsive gaming experience that punches above the monitor’s price point. The VA panel’s high contrast ratio enhances dark games significantly. But the poor stand, lack of ergonomic adjustment, and inaccurate colours out of box mean this isn’t a universal recommendation.

Buy this if you’re gaming primarily, will mount it on a VESA arm, and don’t need colour accuracy. Skip it if you’re doing creative work or want a monitor that’s good at everything rather than excellent at one thing.
