Monitors

The LG 27GL83A-B UltraGear is a 27-inch IPS monitor with 2560 × 1440 (QHD) resolution, a 144 Hz refresh rate and a 1 ms (GtG) response time. It covers 99% of sRGB, is rated at 350 cd/m² typical brightness and supports HDR10.

It is NVIDIA G-SYNC Compatible and supports AMD FreeSync Premium, has 2 HDMI inputs and 1 DisplayPort input, and uses a tilt, height and pivot adjustable stand with 100 × 100 mm VESA mounting.

For most desks, yes. A 27-inch QHD monitor such as the LG 27GL83A-B has 2560 × 1440 pixels, about 78% more than Full HD, with a pixel pitch of 0.2331 mm, so text is sharper and more of a spreadsheet, timeline or web page fits on screen.

Full HD is enough on 24-inch and smaller screens. At 27 inches, Full HD pixels become visible at a normal desk distance, which is why QHD is the usual choice for this size.

144 Hz means the monitor can show up to 144 images per second, compared with 60 on a standard office monitor. Motion in games and while scrolling looks smoother, and the LG 27GL83A-B pairs it with a 1 ms (GtG) response time to reduce blur.

To see 144 Hz, the PC's graphics card must produce that many frames. LG notes the 144 Hz rate is for PC games; consoles run at their own rates, and with AMD FreeSync turned on, console games play at 60 Hz.

Both match the monitor's refresh rate to the frame rate of the graphics card, which removes screen tearing and reduces stutter. G-SYNC Compatible is NVIDIA's verification for its graphics cards, and FreeSync is AMD's technology for its cards.

The LG 27GL83A-B is NVIDIA G-SYNC Compatible, tested and verified by NVIDIA, and supports AMD FreeSync Premium, so it works with adaptive sync on both NVIDIA and AMD graphics cards.

No. The LG 27GL83A-B has no built-in speakers, but it has a headphone output that passes audio from HDMI or DisplayPort to headphones or powered desk speakers.

For video calls at the desk, plan a headset or a webcam with a microphone. A headset also keeps calls private in an open-plan office, where desk speakers would disturb neighbouring seats.

Yes. The LG 27GL83A-B uses a 100 × 100 mm VESA mounting pattern and weighs 4.2 kg without its stand, so it fits standard monitor arms and wall brackets rated for that weight.

Its own stand adjusts for tilt, height and pivot, which covers most desks. An arm is useful when desk space is tight or when two monitors must sit side by side at the same height.

Yes. The stand of the LG 27GL83A-B has a pivot function, so the 27-inch screen can turn from landscape to portrait. In portrait the screen is 1440 pixels wide and 2560 pixels tall, which suits long documents, code and web pages.

Rotate the image in the PC's display settings after turning the screen. The 178° viewing angles of the IPS panel keep colours consistent in either orientation.

Yes, it supports HDR10, the most common HDR video and game format. It is rated at 350 cd/m² typical brightness and covers 99% of sRGB with 1.07 billion colours.

At 350 cd/m² the HDR effect is modest compared with high-brightness HDR monitors, so treat HDR10 support as a compatibility feature rather than the main reason to choose this model; its strengths are QHD sharpness, 144 Hz and 1 ms response.

The LG 27GL83A-B uses 51 W typical and 54 W maximum, and 0.5 W or less in sleep mode. It runs from an external power adapter rated for 100 V to 240 V at 50 or 60 Hz.

That input range covers UAE mains at 230 V without a converter. For several desks, plan one socket per monitor and PC, and use the monitor's sleep mode to cut power use when desks are empty.

The LG 27GL83A-B has 2 HDMI inputs, 1 DisplayPort input and a 3.5 mm headphone output. One PC and one console, or two PCs, can stay connected and be switched from the on-screen menu.

It has no USB-C input, so a laptop that outputs video only over USB-C needs a USB-C to HDMI or USB-C to DisplayPort cable or adapter. Check that the laptop's USB-C port supports DisplayPort video.
