The cheapest way into a four-way adjustable stand. AOC's 24-inch 1080p line has been the default budget recommendation for years, and the SP revision moved it to 165 Hz on an IPS panel that covers sRGB fully. Note the input situation carefully: the HDMI ports are 1.4, which caps them at 144 Hz, so the full 165 Hz only arrives over DisplayPort.

Port speed — can each input carry this panel?
This panel needs 9.9 Gbps at 1920×1080, 165 Hz and 24 bits per pixel, with no DSC to fall back on.
Best for: A first 1080p gaming monitor, or a second screen that still needs to move
The two lists above come from the maker’s specifications and from published third-party measurements, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
Value is the whole pitch, and buyers behave accordingly — this monitor turns up on shortlist after shortlist of near-identical 24-inch 1080p IPS panels in the €115 to €170 range, usually as the cheapest credible option. When owners are happy with it, they are properly happy: one searching for a replacement described it as the best monitor they had owned, and another noted their previous AOC ran ten years before it started tearing. It is also the model people keep failing to buy, since it goes in and out of availability by region and warranty replacements now arrive as a different model entirely.
The failure pattern is what a prospective buyer most needs to know. Faint horizontal lines in a top corner, most visible against white or bright yellow, appear across several separate owner reports, and the people affected had already tried a different cable, a different port, driver reinstalls, resolution and refresh changes, and reseating the graphics card. One owner's lines were severe below 120 Hz and barely visible above it, eleven months into ownership. Beyond that, outright deaths cluster around thirteen to twenty months: flickering that started at thirteen months, a monitor that died at a year and a half after a bottom-edge line appeared, and roughly twenty pixels along the bottom that went miscoloured, then dim, then random, at a year and seven months. One owner trying to file a warranty claim could not get past an authorization error on AOC's support site.
The other recurring problem is buying the right one. The 24G2SP is IPS and the similarly named 24G2S is VA, and one buyer received the VA panel three separate times from the same retailer while trying to order the IPS. Beyond that, 24G2SPU, 24G2SPE and 24G2SPAE/BK all exist alongside it with different stands, hubs and speakers, and video reviews mostly cover the 24G2SPU rather than whichever variant a given shop stocks. Owners moved onto the 24G2SPAE under warranty noticed at once that it gave up the height-adjustable stand.
They show up in a top corner of the screen, are most visible on white or bright yellow, and have survived everything owners have thrown at them: new cables, different ports, driver reinstalls, reseating the graphics card, changing resolution and refresh rate, and power cycling. One owner found the lines were severe at any refresh rate below 120 Hz and nearly invisible above it, eleven months after purchase. Owners consistently conclude it is a hardware fault and pursue warranty rather than a fix.
Owner reports are split. On one side are people whose AOC monitors ran for years, including one that reached ten. On the other is a distinct cluster of failures between thirteen and twenty months — flickering that began at thirteen, a monitor that died outright at about a year and a half, and one that lost roughly twenty pixels along the bottom edge at a year and seven months. Anyone buying should keep the proof of purchase accessible.
This trips up more buyers than any other question, and the most important distinction is not among those at all: the 24G2S, one letter short, is a VA panel rather than IPS, and one buyer received it three times running while trying to order the IPS model. Among the rest, the 24G2SPU adds a USB hub and speakers, and owners transferred onto the 24G2SPAE/BK under warranty found it drops the height-adjustable stand. Most video reviews cover the 24G2SPU specifically.
Buyers have noticed the inconsistency themselves: AOC's own product page advertises FreeSync Premium, while AMD's certification listing shows only basic FreeSync for the same monitor. Separately, one owner reported their on-screen menu showing 'G-Sync' where review videos showed 'Adaptive Sync', which suggests the menu labelling varies with firmware and the connected graphics card.
Buyers ask this and the answer is in the small print: AOC quotes 1 ms MPRT, a motion-blur measurement, rather than a grey-to-grey figure, and the grey-to-grey number is not published on the product page at all. One owner who compared their own panel against review footage felt it showed more ghosting than the videos did. Treat it as a competent budget IPS panel, not as a fast one.
