1,000 Hz. Count 'em, people. It goes without saying this is a niche offering. Refresh aside, the 25-inch, 1080p specs are awfully modest for the price. And the motion clarity benefits over, say, a 500 Hz IPS panel are questionable. But if you want the lowest latency currently possible for esports, this is it.

1,000 Hz. That's 1,000 frames. Every. Single. Second. Welcome to the wild world of the new LG UltraGear 25G590B, the first ever 1,000 Hz gaming monitor.

Well, it's the first gaming monitor capable of 1,000 Hz at full 1080p resolution, as opposed to displays hitting that kind of refresh rate at, say, 720p. The tempting immediate reaction, of course, is to doubt the relevance and benefit of something so fast.

I mean, at what point do diminishing returns kick in with this refresh rate stuff? You could argue that anything above 144 Hz is overkill for most gamers. That was a common view just a couple of years ago. And it's certainly true that 144 Hz is enough for very smooth visuals and a good sense of immediacy and response.

✅ You're an esports pro: The benefits of 1,000 Hz over, say, 500 Hz are marginal. But you might just benefit if you're an esports god.

❌ You want a multi-purpose monitor: High refresh aside, this monitor falls short by just about every other metric compared with similarly-priced monitors.

But as the frame-rate ante has been upped in recent years, to 240 Hz, 260 Hz, 480 Hz and well beyond, that narrative has shifted. In fact, our resident competitive shooter, Jacob, is adamant that 360 Hz is the current sweetspot. Keen esports gamers, it turns out, really can feel the difference, especially in terms of latency, as the refresh rates ramp up. And so here we are in 2026, somewhat inevitably, with LG bursting through the 1,000 Hz barrier.

Aside from the headline refresh rate—the UltraGear 25G590B is actually capable of 1,100 Hz using an "overclock" mode—many of the rest of the spec list is, predictably, pretty pedestrian. That goes with the territory with this type of monitor.

So, we're talking 25-inch panel size and IPS technology. Brightness comes in at 400 nits, contrast is a mere 1,000 to 1 and there's only the most basic DisplayHDR 400 certification. So, this panel will decode an HDR signal, but it can't really render HDR visuals.

Again, all of that is expected in this class of gaming panel. It's not about high-DPI visuals or OLED-style per-pixel lighting. It's all about speed. Actually, it's primarily about one aspect of speed: latency. The other major metric of speed, pixel response, isn't such an obvious win for theUltraGear 25G590B.

LG has rated it at 1 ms for the most often quoted grey-to-grey transition. That's pretty quick for an IPS monitor, but not actually exceptional. Not when there are 0.5 ms LCD-based monitor models knocking around, never mind the OLED crew which all clock in at a mere 0.03 ms.

That's something of a surprise given the absolutely cutting-edge refresh rate. On paper, the 1 ms response perfectly matches the 1,000 Hz refresh. But then measures of pixel speed are infamously mercurial. There isn't actually an enforced, or even widely agreed upon metric for pixel response in the monitor industry. So, response ratings are really only ever a rough guide.
