The proof
Performance
The 75Hz refresh rate is a small step up from the standard 60Hz, and it's noticeable when scrolling or moving windows around. But that's where the excitement ends. The display sits at the 39th percentile overall, which means it's solidly average for this type of product. The IPS panel gives you decent viewing angles, but the color performance lands at the 16th percentile, which is a real weak spot. If you care about color accuracy, this isn't the panel for you.

vs Competition
Stacked against the competition in our database, the S2421HS looks outclassed. The ASUS ROG Strix XG27UCDMG and LG UltraGear 27GX790A-B are in a completely different league with 4K resolution and OLED panels, though they cost more. The Samsung Odyssey OLED G6 G60SF and Alienware AW2725D offer high refresh rates and better color for gamers. Even the MSI MPG 271QR QD-OLED X50 blows this Dell away on features. The only thing the S2421HS has going for it is the ergonomic stand, which sits at the 79th percentile. Everything else is middle-of-the-pack or worse.

Price
Value & Pricing
At $336 USD, this monitor is a tough sell. You can find 24-inch 1080p IPS monitors with similar specs for significantly less, and for that money you're creeping into 1440p territory or high-refresh-rate gaming displays. The ergonomics are nice, but they don't justify the premium. This feels like a $150 monitor wearing a $300 price tag.

Overview
The Dell S2421HS is a basic 24-inch 1080p IPS monitor that gets the fundamentals right but doesn't do much else. The one thing to know? It's a comfortable, ergonomic office display that's wildly overpriced at $336 USD. You're paying premium money for a monitor that competes in a budget category.
Common Questions
Q: Is this monitor good for gaming?
Not really. The 75Hz refresh rate is better than 60Hz, but there's no adaptive sync, no DisplayPort, and the color performance is weak. If you're gaming, look for something with at least 144Hz and better color.
Q: Can I mount this monitor on a VESA arm?
Yes, it supports VESA mounting. But honestly, the included stand is the best part of this monitor, with full height, tilt, swivel, and pivot adjustability. You might not even need an arm.
Q: Is the color accuracy good enough for photo editing?
No. The color performance sits at the 16th percentile in our database, which is near the bottom. If you're doing any color-critical work, this panel will frustrate you. Look for something with better color coverage.
Who Should Skip This
If you're looking for a gaming monitor, a color-accurate display for creative work, or anything with modern connectivity, this isn't it. Go get a high-refresh-rate panel from LG or ASUS instead. If you just need a basic office monitor, don't pay $336 for this. Find a cheaper 1080p IPS display and call it a day.
Verdict
Skip it. The Dell S2421HS is a perfectly fine monitor trapped in a bad price. If you find it on sale for under $200, it's a reasonable office display with great ergonomics. At $336, you're getting fleeced. There are better options at this price point, and better budget options if you just need a basic 1080p screen.
