27″ Dual-Mode Gaming Monitor

This 27-inch IPS gaming monitor delivers 4K UHD resolution at 144Hz and switches to FHD 1080p at 288Hz for competitive responsiveness. The panel covers 100% sRGB with 10.7 billion colours, 450 cd/m² brightness and a 1500:1 contrast ratio. Wide 178° viewing angles maintain colour consistency from almost any position. A 1 ms response time keeps motion sharp in fast-paced scenes.

Suits gamers who need both high resolution

The dual-mode design lets you prioritise detail in single-player titles or frame-rate in esports without changing hardware. USB-C with Power Delivery, HDMI 2.1, DisplayPort 1.4, USB OTG and a 3.5 mm jack cover laptops, consoles and phones. Built-in dual 2W speakers and a 100×100 mm VESA mount add desk or wall flexibility. Buyers who require a larger screen, higher 4K refresh rates, HDR certification or a curved panel should look at other models.

Dual-mode refresh specification

The single specification that decides suitability is the ability to run 3840×2160 at 144Hz or 1080p at 288Hz on the same panel. If your workflow or gaming preference demands one fixed native resolution and refresh combination, a single-mode monitor may be simpler. Verify that your graphics source can output the desired mode over the available ports before purchasing.

Questions about this item

What refresh rates do HDMI 2.1 and DP 1.4 actually deliver on this monitor?

HDMI 2.1 and DP 1.4 both support the dual-mode specification: 4K UHD at 144 Hz and FHD 1080p at 288 Hz, so the interface does not cap the panel's advertised rates.

What physical mounting pattern does the 27-inch LS Series use?

The monitor has a 100 x 100 mm VESA mount, allowing attachment to standard monitor arms, wall brackets or the included lightweight LS stand.

How do I switch between 4K 144 Hz and 1080p 288 Hz without getting a black screen?

Change the resolution and refresh rate in your OS display settings or GPU control panel first, then confirm the new mode; the panel will handshake over HDMI 2.1 or DP 1.4 without power cycling.
