Buy the Acer KB272 G0bi.

These are the same monitor on paper, and one of them costs 70% more for it.

What was compared

1. Nearly identical monitor, $70 cheaper
Both are 27-inch FHD IPS panels with 1ms response and FreeSync. The Dell asks $169.99 for essentially the same core experience the Acer delivers at $99.99.
2. VGA port the Dell doesn't have
Acer kept a VGA input alongside HDMI, which matters if you're plugging in an older office PC, a projector, or a laptop dock. Dell went HDMI-only, so it quietly locks out anyone with legacy gear.
3. Acer tells you its color coverage, Dell doesn't
Acer specs 99% sRGB right on the listing, which is what you want for photo work or accurate colors. Dell's page never states a gamut number at all, which on a budget monitor usually means it's nothing to brag about.
4. Built-in eye tech beats a certification sticker
Acer names two actual features, a Bluelight Filter and Flickerless Technology, baked into the panel. Dell leans on a TÜV 3-star badge, which is a third party stamp, not a feature you can point to and understand.
5. Yes, Dell has 144Hz and better reviews. Doesn't matter.
Dell's 4.6-star rating and 144Hz over Acer's 120Hz are real, but 120Hz already looks smooth for spreadsheets, browsing, and most games, the extra 24Hz only shows up in twitchy competitive titles. Acer is a long-running office monitor line, this listing just lacks the review count, not the reliability.
