Acer KB272 G0bi 27" 120Hz IPS Monitor

A 27-inch 1080p IPS panel running at 120Hz, which is the trade this monitor asks you to make: more screen and smoother motion than the 24-inch Philips beside it, at the cost of pixel density — the same 1920×1080 stretched across 27 inches works out to 81 pixels per inch. Covers 99% of sRGB with 178° viewing angles, carries FreeSync from 48 to 120Hz, and mounts on a 100×100 VESA arm. Ports are one HDMI and one VGA.

Pros

✓ 120Hz on a 27-inch panel at this price — DisplayNinja found the jump from the usual 60–75Hz visible just moving the cursor and scrolling, not only in games
✓ IPS panel covering 99% of sRGB with 178° viewing angles, so colour holds up off-axis and it is usable for entry-level colour work
✓ Adaptive-Sync from 48 to 120Hz (FreeSync compatible), which keeps video and games tear-free without a G-Sync premium
✓ Input lag measured around 4ms by DisplayNinja — low enough that nothing feels delayed
✓ 100×100 VESA mount, so it fits the same arm the Philips in this subcategory does
✓ A joystick on the back drives the menu, and the OSD carries PiP/PbP, gamma, 6-axis hue and saturation and automatic input detection
✓ Low blue light filter and a flicker-free backlight, with the caveat in the cons below
✓ 4.6★ across 2,024 ratings, and a top-ten seller in Amazon's Computer Monitors

Cons

– 1080p across 27 inches is 81 pixels per inch. DisplayNinja calls the result "a bit pixely" against a 24-inch 1080p screen, and the Philips beside it is 23.8 inches at about 93 PPI — text is where you will see the difference, all day
– 250 nits is the floor for a modern LED-backlit LCD. Fine in an ordinary room; facing an uncurtained window it will not out-argue the glare
– One HDMI 1.4 and one VGA, and the VGA is capped at 60Hz — so the 120Hz runs over the single HDMI port, and there is no DisplayPort and no USB-C to dock a laptop with
– The stand tilts −5°/25° and does nothing else: no height, no swivel, no pivot. Budget for the VESA arm if the screen has to sit at a particular height
– The listing's "1ms" is MPRT through VRB, Acer's backlight strobing — it cannot run at the same time as Adaptive-Sync, it costs brightness, and it is also the one setting that makes the "Flickerless" claim stop being true
– IPS contrast is 1000:1 with the usual IPS glow in a dark room. The Philips next to it is a VA panel and does blacks properly; that is the half of the comparison this monitor loses
– It is the cheap seat, not the good one. The Samsung Odyssey G55C in this subcategory is 32 inches of 1440p at 165Hz for roughly twice the money — more screen, sharper text and 2,500:1 contrast — and the gap is wide enough to be worth saving for
– The 2,024 ratings cover the whole family — six listings from 19.5 to 27 inches and from 75Hz to 144Hz share this page, so a review may be describing a different size or a different refresh rate

ASUS ProArt PA278QV 27" QHD Monitor

Colour that is right out of the box, on a stand that actually moves

The one monitor here bought for accuracy rather than speed: 27 inches of 1440p IPS at 108 pixels per inch — the sharpest text in this subcategory — factory calibrated to Delta E under 2 and covering 100% of sRGB and Rec.709. The stand is the other half of the argument: 150mm of height, 90° of pivot and swivel each way, against the tilt-only stands on the other three. It runs at 75Hz, and that is the trade.

HP 24mh 24" FHD IPS Monitor

A screen that arrives, adjusts and works, with the fewest complaints of any here

The best-reviewed monitor in this subcategory and the least exciting one: 23.8 inches of 1080p IPS at 75Hz, on a stand that raises 100mm, tilts and pivots to portrait, with DisplayPort, HDMI, VGA and a pair of 2W speakers built in. What it buys is the absence of problems — 4.7★ across 25,427 ratings with no review theme where complaints outnumber praise. What it does not buy is any headline number: no Adaptive-Sync, 250 nits, 1000:1.

KOORUI G2412V 24" 180Hz VA Monitor

The most contrast per dollar of any screen here, if one HDMI port is enough

A 23.8-inch 1080p VA panel at 180Hz for around ninety dollars, and the reason to look at it is a number the listing undersells: TFTCentral measured 4,924:1 contrast against the 3,000:1 KOORUI advertises — roughly double the Samsung VA here and five times the two IPS panels. It is also the most stripped-back screen in this subcategory. One HDMI, one VGA, a tilt-only stand, and nothing else.
