Frequently asked questions

LG UltraGear OLED 27" — what you need to know

Is this monitor rental-only, or can I buy it outright? +

Either way. Monthly rental (LG Subscribe): promo RM80/mo (months 1–9), then N/P RM120/mo until the contract ends at 60 months (5 years). Outright purchase: RM4,499.

Is a graphics card (GPU) included? +

No — a graphics card is NOT included in the package. DisplayPort, HDMI and USB A-to-B cables are included.

Does the DisplayPort 2.1 on this monitor support UHBR20/80Gbps bandwidth? +

LG's official specification (All Spec) only confirms "DP Version 2.1" and QHD support up to 480Hz — UHBR20/80Gbps bandwidth is NOT confirmed in the official source. A DP 2.1-compatible GPU is required to reach the full 480Hz.

Is 480Hz the maximum or the normal refresh rate? +

480Hz is the MAXIMUM refresh rate. LG claims this is the world's fastest OLED refresh rate based on published specifications as of the time of publication (November 2024).

Does the 1300-nit brightness stay across the whole screen? +

No — 1300 nits is the PEAK brightness at APL 1.5% (Average Picture Level), not continuous full-screen brightness. Typical brightness is 275cd/m² at APL 100%.

Can this OLED suffer burn-in / afterimage? +

LG itself confirms burn-in risk exists on all OLED panels and provides OLED Screen Move, Screen Saver and Image Cleaning features to reduce the risk — however these features do NOT guarantee 100% prevention of afterimage/burn-in.

What is the actual size of this "27-inch" monitor? +

Marketed as 27 inches (standard industry display-class naming), while the actual panel specification (All Spec) is 26.5 inches (67.3cm) — this is normal for display-class naming, not an error.

6) Low Blue Light

UL certificates: Flicker-Free Display (OLED) A196009, Discomfort Glare Free V563481, Low Blue Light Hardware Solution Platinum V745051. Actual experience varies according to the user's computing environment and conditions.

Performance comparison is against models without sync technology. Network-related errors or delays may occur in applicable content/services.

9) VESA ClearMR 21000

LG states this is the first OLED gaming monitor to achieve ClearMR 21000. Clear Motion Ratio exceeds 19,500 under the certification reference.

10) Compact and Sleek

Simulated imagery may differ from real use. Stand specifications should be taken from the actual mechanical values rather than estimating from imagery.

11) DTS Headphone:X

13) 24-inch Mode

Use: OSD → Input → Aspect Ratio → 16:9 24.

14) Crosshair / FPS Counter

20) Customer Reviews — Not Displayed

Reviews on LG's official product page (4.6/5, 82 reviews) are sourced from regional lg.com sites (e.g. Chile), some marked "Originally posted on…" meaning from another country's LG page — not LG Ohsem Malaysia customers, so they are not shown here as local testimonials.
One review mentions an expectation of UHBR20 that is not confirmed by the official specification — customer reviews are not used to rewrite the official technical specification.

21) Pricing & Availability

Prices, promotions and availability can vary by store and online, and are subject to change without prior notice. Quantities may be limited.
