LG has quietly raised the bar for competitive displays with its new UltraGear 27GX790B, a 27-inch OLED monitor that pushes refresh rates into territory previously seen only in prototypes. It’s clearly aimed at tournament players and fast-paced shooters, but the tech choices behind it deserve a closer look.
Why a 720Hz panel matters — and when it doesn’t
At first glance, 720Hz sounds like a headline grabber. And it is: the 27GX790B can hit a blistering 720Hz, but only at 720p (HD) resolution. That extreme frame rate is ideal if you trade visual fidelity for the absolute lowest latency and the smoothest motion — think high-tier esports and titles like Counter-Strike 2 where every millisecond counts.
If you prefer sharper visuals, LG offers a more balanced option: 1440p at up to 540Hz. That still outpaces most high-end gaming monitors while delivering noticeably better image detail than 720p. In short, the monitor gives players a menu of choices: prioritize frames or prioritize pixels.
The 27GX790B uses a 27-inch Primary RGB Tandem WOLED panel, which is part of what enables both the low response times and strong HDR performance. LG quotes a 0.02ms response time, 335 nits peak SDR brightness and up to 1500 nits peak in HDR. It also carries DisplayHDR True Black 500 certification and covers 99.5% of the DCI-P3 color space, so color accuracy isn’t an afterthought even at extreme refresh rates.
- Refresh rates: up to 720Hz at 720p; up to 540Hz at 1440p
- Panel: 27-inch Primary RGB Tandem WOLED
- Response time: 0.02ms (quoted)
- Brightness: 335 nits SDR, up to 1500 nits HDR peak
- Color & HDR: DisplayHDR True Black 500, 99.5% DCI-P3
- Ports: HDMI 2.1, DisplayPort 2.1, USB-C (1x), USB-A (2x), 3.5mm audio
- Extras: adjustable stand and rear RGB lighting
Connectivity is modern and competitive-player friendly: DisplayPort 2.1 and HDMI 2.1 for high-bandwidth feeds, a USB-C port for convenience, and extra USB-A ports for peripherals. The adjustable stand and rear RGB lighting are small but welcome touches for desk customization.
Are there downsides? The biggest caveat is the resolution trade-off required to reach 720Hz. For most gamers, 1440p at 540Hz will be the sweet spot, offering an excellent balance of clarity and speed. Meanwhile, industry prototypes pushing toward 1000Hz are already in development, so we may see even higher frame rates in the near future.
Who should consider the UltraGear 27GX790B? If you’re a competitive player chasing every possible edge — higher frame rates and ultra-low latency — this monitor is compelling. If you value cinematic visuals or play single-player titles, a high-refresh 1440p or 4K screen that prioritizes resolution may be a better fit. LG hasn’t finalized global pricing and availability yet, but the 27GX790B clearly signals the company’s intent to dominate the competitive OLED segment.

Looks impressive techwise but kinda overhyped. OLED + 0.02ms + 1500 nits = sexy specs, yet 720p for 720Hz? nah, I'll take 1440p@540Hz, just sayin

720Hz at 720p? sure sounds like a flex, but is anyone really gonna play at that res competitively... 1440p/540Hz feels like the real sweetspot, curious about actual input lag numbers
