## Frequently asked questions

### Who is the LG UltraGear 27GX790A for?

Nobody we can recommend over the alternatives, even though it is a strong current high-refresh OLED. It is a 480Hz 1440p panel with DisplayPort 2.1 and excellent contrast, and it ranks highly in a current OLED comparison, but it sits in D tier on our gaming monitors board because the evidence gives less confidence about long-term support and firmware longevity. Buy the Alienware AW2726DM in S tier for safer ownership, or the Asus ROG Swift OLED PG27AQDP in C tier if 480Hz competitive play is the goal.

### What is the better alternative to the LG UltraGear 27GX790A on this board?

The Alienware AW2726DM is the top pick and the safer years-long purchase. If you want an LG OLED specifically, the LG 27GX700A-B in B tier is the board's better-ranked LG, a 280Hz 1440p OLED with a near-instantaneous response time. If 480Hz is the requirement, the Asus ROG Swift OLED PG27AQDP has a broader testing record and sits a tier higher.

### Why is the LG UltraGear 27GX790A in D tier?

Support uncertainty, not performance. The verdict says the available evidence gives less confidence about long-term support and firmware longevity, and the cons add that model-specific warranty and firmware support are less clear and that it ranks behind several more compelling OLED choices. On the screen itself the pros are strong: high-refresh OLED performance, excellent contrast and image quality.

### What goes wrong with the LG UltraGear 27GX790A?

OLED burn-in is listed twice in the cons as a long-term concern, and automatic brightness limiting can affect use, dimming the screen on large bright scenes. Beyond those standard OLED risks, the board flags unclear model-specific warranty and firmware support, which matters because firmware updates are how OLED makers improve burn-in handling over time. No hardware fault is recorded.

### What does DisplayPort 2.1 on the LG UltraGear 27GX790A do?

It provides enough bandwidth to run 1440p at 480Hz without display stream compression, which older DisplayPort versions cannot manage at that rate. The practical benefit is small, since compression is visually lossless, but it future-proofs the connection. To use it you need a graphics card with a DisplayPort 2.1 output and a cable certified for the higher bandwidth. On an older card the monitor still works over DisplayPort 1.4 with compression.

## What this tier means

- D: Weak. Hard to recommend when better options cost similar money.

## How to read this

- Each category is researched in four independent runs, one per lens (expert consensus, value, reliability, community pulse). Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand.
- LP is this product's points on its own category ladder. It is comparable within a category and not across categories.
- Link status reports what our pre-publication link check found when it fetched the cited URL. It says nothing about the quality of the review.
- A citation with no usable link is listed rather than dropped, and is excluded from the counted total above.
