LG UltraGear 1000Hz — gaming monitor pushes absurdity in service of responsiveness
1000Hz, 0.03ms, $799 USD — LG surpasses Asus and sets the bar at an absurd level
LG announces the UltraGear 25G590B, a 1000Hz 25-inch FHD monitor that breaks the refresh rate record. Compatible with NVIDIA Reflex and G-Sync, 0.03ms GTG response. Price $799 USD. Who is it for, and does 1000Hz actually change anything? We separate reality from marketing.

1000Hz — marketing figure or real advancement?
When Asus released a 500Hz monitor in 2024, the gaming community's reaction was mixed. When LG announces 1000Hz in 2026, the question is even sharper: can you really see the difference between 500Hz and 1000Hz? The short answer: no, the human eye can't distinguish the difference at these rates. The long answer is more nuanced.
The real gain at 1000Hz isn't visual — it's systemic. NVIDIA Reflex measures system latency (from click to display) in milliseconds. At 1000Hz with Reflex enabled, that system latency drops below 5ms on certain configurations, versus 8-10ms on a standard 360Hz. In high-level competitive FPS, this translates to more precise reactions.

Who it's actually for
Let's be honest: the LG UltraGear 1000Hz is for a very specific segment. To benefit from it, you need: a GPU capable of producing 1000+ FPS in-game (RTX 5090 or RX 9070 XT at 1080p on light games like CS2, Valorant, Overwatch 2), NVIDIA Reflex enabled, playing competitive FPS titles seriously.
- Competitive FPS players who play at a high level (gold+, diamond+, GM+)
- GPU configuration capable of producing 800-1000+ FPS at 1080p on their games
- Unconstrained hardware budget for the setup
Who it's NOT for
If you play RPGs, open world games, RTS or narrative games, a 144Hz or 240Hz screen is more than sufficient. If you play FPS casually, a 360Hz is already beyond what you'd perceive. 1000Hz is a product for an extreme niche market — not an upgrade for the average gamer.
La Meute QC verdict
The LG UltraGear 1000Hz is a tech showcase more than a mainstream product. For $1,099 CAD, you could have an excellent 1440p 240Hz monitor with much better image quality for 99% of use cases. If you play CS2 at T2-T3 level or Valorant Radiant, and your PC outputs 1000 FPS in those games, then yes — it's the most responsive monitor available. For everyone else: invest that money elsewhere.
