Is the LG UltraGear GX9 worth it over a 34-inch ultrawide?

It gives you much more screen area and 5120 × 2160 resolution instead of 3440 × 1440, so text and games look sharper. The trade-off is a bigger footprint and a heavier GPU load at native resolution.

Can it really run at 330 Hz?

Yes, but only in the 1080p mode. At native 5120 × 2160 the refresh rate tops out at 165 Hz.

Does it work with both G-Sync and FreeSync?

It is G-Sync Compatible and FreeSync Premium Pro certified, so it works with Nvidia and AMD adaptive sync setups.

What do I need to drive 5120 × 2160 at 165 Hz?

You need a recent high-end GPU and DisplayPort 2.1 or HDMI 2.1. Plan on a top-tier card for modern games at native resolution and high frame rates.

Is the 800R curve too aggressive?

An 800R curve is tight and wraps the panel around you, which suits a centered seating position. Some users prefer a gentler curve for office work.

Ultrawide monitors usually drop during major sales events and when a new model is announced. Track the price history and buy below the recent range.
