A 750Hz gaming monitor has come out of nowhere at CES 2025 – but I’m getting a little sick of this one-upmanship on the refresh rate front
- The Koorui G7 monitor was demonstrated on the show floor at CES 2025
- It uses a TN panel (instead of IPS) to achieve that 750Hz refresh rate
- It also offers a 0.5ms response time and more impressive color accuracy than expected with a TN screen
CES 2025 has witnessed a series of announcements for gaming monitors that offer super-high refresh rates, and we have a new champion on the Hertz battlefield: a 750Hz display, no less.
This is the Koorui G7 which airs at CES as a 24.5-inch Full HD gaming monitor with a 750Hz refresh rate coupled with a 0.5ms response time.
Koorui, a Chinese supplier you may not have heard of – but will probably hear more about – already has quite a number of attractively priced gaming monitors on the market, although a 750Hz screen obviously won’t come cheap.
The company actually announced the Koorui G7 before CES, but we just got a glimpse of it on the show floor thanks to a video uploaded to the company’s YouTube channel – check it out below (you’ll get a quick look at the G7 at the beginning of the clip – press the pause button).
Apart from the 750Hz refresh rate, other key specs of the G7 include HDR400 support and 95% DCI-P3 coverage, the latter of which is impressive considering this is a TN panel. Normally color reproduction is a weak point of TN compared to IPS (which is what most monitors are these days), so it seems like Koorui is trying to ensure that the G7 doesn’t fall (too) flat in this regard. (TN panels are a good choice for gaming monitors because of their inherently fast response times and ability to achieve high refresh rates, as we certainly see here – but not their color accuracy, vibrancy, or viewing angles).
The Koorui G7 comes with all the usual features like a low blue light mode, flicker-free technology, and ergonomics that include height adjustment, tilt, and swivel. You also get three HDMI 2.1 ports in addition to a DisplayPort 1.4 connector.
Koorui is part of HKC, a display giant in China, and this monitor is expected to be released sometime in 2025 (at least in Asia – and hopefully elsewhere in the world too).
Analysis: refreshingly pointless?
We’ve already seen new 600Hz monitors at CES 2025 (from MSI and BenQ) that rival Acer’s existing 600Hz efforts, the Nitro XV240 F6, a monitor now available in China and coming to the US and Europe soon.
However, these panels have already been let down by this 750Hz effort, and not by a long shot. The obvious question with these types of high-end gaming monitors, however, is: how far should we go with colossal refresh rates? Isn’t 750Hz getting weird?
Well, we’ve argued in the past that 600Hz is starting to get into some pretty ridiculous territory, and that’s certainly the case with 750Hz. Will the difference between 600 Hz and 750 Hz even be noticeable to the average human eye? Frankly, that won’t be the case, and as you climb the high refresh rate ladder towards the dizzying heights of 1000Hz (which will no doubt happen soon enough), there are sharply diminishing returns.
These displays are truly intended for top-level competitive gamers. For starters, you’ll need to be able to afford a gaming PC that can hit 600 or 750 frames per second to match that refresh rate (and do it consistently – or ideally as a baseline, even). And even with the less demanding esports titles like Counter-Strike 2 or Valorant, which are made to run smoothly and slickly by keeping the visuals relatively tame, that’s a tough ask for anything less than a fully featured hyper-expensive gaming PC .
It may be true that the most experienced professional gamers can tell a difference in, say, a 500 Hz panel (which OLEDs are now reaching, by the way) versus a 600 Hz or 750 Hz monitor. That would be in terms of the feeling of gameplay – thanks to the smoother and more consistent display of frames (better frame time) thanks to a super fast refresh rate display. But we mere mortals won’t notice this increasingly stable nature of a beast of a refresh rate screen.
Still, big numbers are always fun to watch, and you can undoubtedly bet on bigger numbers in the not-so-distant future. However, it’s worth remembering that there’s a lot more to a monitor than just its refresh rate. I’m curious to see how the picture quality turns out on this TN panel from Koorui – to find out if this is more of a PR exercise, or a truly great gaming display (for the few who might need it and can afford it).
