BenQ GW2491 23.8" 100 24" Review
The BenQ GW2491 makes a smart trade: it swaps flashy specs for a smoother 100Hz refresh rate and serious eye comfort features, making it a great pick for budget-focused desk duty.
The 30-Second Version
The BenQ GW2491 is a solid budget IPS monitor that makes one smart upgrade: a 100Hz refresh rate for smoother everyday use. Its display is just okay, but the eye comfort features are top-notch. At a refurbished price near $100, it's a fantastic value for a second screen or basic office work. Gamers and anyone needing a bright screen should skip it.
Overview
Let's talk about the BenQ GW2491. This is a 24-inch, 1080p IPS monitor that's trying to do one thing really well: be a solid, no-nonsense screen for your desk. It's not trying to win any esports tournaments or be the centerpiece of a Hollywood color grading suite. It's the monitor you buy when you just need a reliable second screen, or a primary one for work, without any fuss.
Who is this for? Honestly, it's for the budget-conscious office worker, the student setting up a home desk, or anyone who needs an extra monitor that won't break the bank. The 100Hz refresh rate is the interesting bit here. It's a small step up from the standard 60Hz you find on most basic office monitors, promising a slightly smoother feel when scrolling through documents or web pages. It's a nice little quality-of-life upgrade.
The whole package is built around BenQ's 'EyeCare' philosophy. You get flicker-free backlighting, a low blue light mode, and even a weird but potentially useful 'ePaper' mode that turns the screen monochrome for reading. It's clear this monitor is designed for people who stare at screens all day and just want their eyes to hurt a little less by 5 PM.
Performance
Performance-wise, the GW2491 sits in a comfortable middle ground. Our database puts its overall performance score right around the 53rd percentile. That translates to 'perfectly fine for everyday tasks.' The 100Hz refresh rate is its main performance claim, and it does deliver a perceptibly smoother cursor movement and window dragging compared to a 60Hz panel. It's not a gaming monitor, but that extra fluidity is nice for general desktop use.
Where it shows its budget nature is in the display specs. The 250-nit brightness is just okay, and it lands in the 23rd percentile for display quality overall. This means it can struggle in very bright rooms, and the contrast isn't going to blow you away. The 99% sRGB color coverage is solid for the price, ensuring colors look accurate and natural for web browsing, office apps, and casual media consumption. Just don't expect the punchy, vibrant HDR you see on pricier screens.
Pros & Cons

Value & Pricing
Here's where things get weird. The listed price range across vendors is absolutely bonkers, from $75 to over $35,000. Ignore the high end; that's clearly a data error or a placeholder. The real value conversation happens at the low end. If you can find this new for around $120-$150, or better yet, snag a refurbished unit for closer to $75-$100, it becomes a very compelling buy. At that refurbished price, you're getting a reliable IPS panel with better-than-60Hz motion and good connectivity for less than a cheap keyboard. Just make sure you're buying from a reputable seller with a good return policy.
Price History
vs Competition
Stacked against common competitors, the GW2491 carves out a specific niche. Compared to something like an LG UltraGear or MSI MAG monitor, you're giving up high refresh rates (144Hz+), faster response times, and gaming features for better eye care and a lower price. Those are pure gaming displays; this is not.
A more direct competitor might be a basic 24-inch IPS from Dell or HP. The BenQ often beats them on paper with its 100Hz panel and thinner bezels, but might lose on brand reputation for business use or warranty support. Compared to an ASUS ProArt, you're giving up professional color accuracy and calibration. The BenQ's trade-off is clear: you sacrifice peak display performance and fancy features to get a smoother, more comfortable viewing experience on a budget.

Common Questions
Q: Is the 100Hz refresh rate worth it over 60Hz for office work?
Yes, it's a noticeable quality-of-life improvement. Scrolling through long documents, spreadsheets, and web pages feels significantly smoother and less jerky. It won't make you work faster, but it reduces eye strain during long sessions and just makes the whole desktop experience feel more fluid and modern.
Q: How bad is the 250-nit brightness in practice?
It's fine for most indoor environments with controlled lighting. If your desk is right next to a big sunny window, you might struggle with glare and find the image looks a bit washed out. For a typical home office or cubicle with overhead lighting, 250 nits is perfectly adequate, but it's the monitor's main spec compromise.
Q: Can you use this for casual gaming?
You can, but it's not ideal. The 100Hz is nice, but the 5ms response time may cause some noticeable motion blur in fast-paced games like shooters or racing titles. It's perfectly fine for slower games like strategy titles, indie games, or older classics. If gaming is a primary focus, a monitor with a faster 1ms response time would be a better choice.
Q: Does it have speakers?
No, the GW2491 does not have built-in speakers. It does have a headphone jack on the back, so you can easily connect your own speakers or headphones directly to the monitor, which is a handy feature that many basic monitors omit.
Who Should Skip This
Hardcore gamers should look elsewhere. The 5ms response time and lack of adaptive sync (like FreeSync or G-Sync) mean you'll get more motion blur and potential screen tearing than on a dedicated gaming monitor. Also, if your workspace is flooded with natural light, the 250-nit brightness will be a constant frustration. You'll be cranking the brightness to max and still squinting.
Professional photographers, video editors, or graphic designers should also skip this. While color accuracy is good, the monitor lacks hardware calibration options, wide color gamuts like DCI-P3, and the high brightness needed for HDR work. For those users, a monitor like an ASUS ProArt or Dell UltraSharp, while more expensive, is a necessary tool for the job.
Verdict
If you need a secondary monitor, a budget-friendly primary screen for office work and web browsing, or you're particularly sensitive to eye strain, the GW2491 is an easy recommendation. Its combination of 100Hz smoothness, good connectivity, and legit eye comfort features is hard to beat at the right price. Just pair it with a monitor arm if you need height adjustment.
However, if you're a gamer, a content creator needing color-critical work, or you work in a very bright environment, you should look elsewhere. The brightness and response time aren't up to snuff for those uses. For those folks, spending a bit more on a proper gaming monitor or a brighter, more adjustable business panel would be a much better investment.
