The proof
Performance
The 75Hz refresh rate and 5ms response time put this firmly in casual gaming territory, and that's fine. What surprised us is how well the IPS panel holds up for the price. Colors look accurate out of the box, and the FreeSync support actually makes a difference if you're running an AMD card. The 72% NTSC coverage is nothing to write home about, but for office work, web browsing, and lighter games, it's more than adequate. Just don't expect to win any esports tournaments on this thing.

vs Competition
The LG 24MP400-B sits in a weird spot. It's not as feature-rich as the Dell S2725QC, which gives you 4K and USB-C for more money, and it's nowhere near the gaming chops of the MSI MAG 271QPX QD-OLED or the ASUS TUF Gaming VG34VQL1B. But those are all significantly more expensive. For a budget 1080p IPS panel, the LG's main competition is really other 24-inch budget monitors, and it holds its own there. The BenQ MA270U is a step up if you want better color accuracy for creative work, but you'll pay for it.

Price
Value & Pricing
At around $160 USD, this is a solid deal. You're getting a 24-inch IPS panel with FreeSync and a design that looks like it belongs on a more expensive desk. The lack of height adjustment and single HDMI port sting a bit, but for the money, it's hard to complain too loudly. If you need a second monitor or a budget primary for work and light gaming, this is a no-brainer.

Overview
The LG 24MP400-B is a budget 24-inch IPS monitor that punches above its weight for everyday work and casual gaming. The one thing to know: you're getting a genuinely nice-looking 1080p panel with FreeSync and 75Hz for around $160, and most people who buy it end up pretty happy. It's not going to blow anyone away on paper, but the real-world experience is better than the spec sheet suggests.
Common Questions
Q: Is this monitor good for gaming?
For casual gaming, yes. The 75Hz refresh rate and FreeSync support make games feel smoother than a standard 60Hz monitor. But if you're into competitive shooters or fast-paced esports, you'll want something with a higher refresh rate and lower response time.
Q: Does it have built-in speakers?
No, there are no built-in speakers. You'll need external speakers or headphones. The single HDMI port carries audio, but you'll need something to actually play it through.
Q: Can I mount this monitor on a VESA arm?
Yes, it has a standard 75x75mm VESA mount. The included stand is basic with only tilt adjustment, so if you want height adjustment or a cleaner setup, a VESA arm is a solid upgrade.
Who Should Skip This
If you're looking for a high-refresh gaming monitor or something with USB-C connectivity, this isn't it. Go grab the MSI MAG 271QPX QD-OLED if you want top-tier gaming performance, or the Dell S2725QC if you need USB-C and 4K. The LG is for people who want a solid, affordable everyday monitor and don't need the extras.
Verdict
The LG 24MP400-B is a great budget monitor for office work, web browsing, and casual gaming. It's not going to impress anyone with its specs, but the IPS panel looks good, FreeSync works, and the nearly borderless design is a nice touch. If you need a reliable 24-inch 1080p monitor without spending a fortune, this is one of the best options out there. Just know what you're getting: a solid everyday monitor, not a gaming powerhouse.
