LG 34U640B-B, a 34-inch curved ultrawide monitor with 3440 x 1440 WQHD resolution and a 144Hz refresh rate, is in stock at Mascom International, priced at KSh 71,000. Each unit is brand new and sealed. Its VA panel curves at 1800R, which means the edges bend gently toward your eyes so the far corners stay readable. The 21:9 shape gives about a third more width than a standard 16:9 screen of the same height. A single USB-C cable carries picture and data and charges a laptop at up to 65W. See the LG 34U640B-B working at our Kimathi Street store in the Old Mutual Building, Nairobi CBD.
Designed for financial analysts, logistics coordinators, software developers and content creators, the LG 34U640B-B handles the jobs that cramp a single laptop screen. Forex traders in Kilimani watch live charts beside a trading platform. Logistics teams in Industrial Area track shipments in one window while updating a spreadsheet in another. Video editors get a longer timeline without endless scrolling. The KVM switch on the LG 34U640B-B lets one keyboard and mouse control two computers, so a work laptop and a home desktop share one desk without a second set of peripherals. Scrolling through long reports also looks smoother than on a 60Hz office screen.
Unlike other electronics retailers in Kenya that treat ultrawides as gaming-only items, Mascom International sets this model up for office and home-office buyers and shows you how the KVM and USB-C features work. Buyers throughout Kenya report that one curved ultrawide replaces a messy two-monitor setup, with no bezel splitting the middle of the picture. The LG 34U640B-B also suits PC gamers who want a wider view in racing and open-world titles. Walk into our Nairobi CBD showroom to sit in front of it, or order on WhatsApp and pay on arrival in any of the 47 counties.
Common Questions About the LG 34U640B-B
What is the LG 34U640B-B price in Kenya?
The LG 34U640B-B sells for KSh 71,000 at Mascom International in Nairobi, brand new and sealed with a 24-month warranty. The box carries the power adapter and cord plus HDMI, DisplayPort and USB-C cables, so a laptop or desktop connects straight away with no extra purchase. You pay on arrival when it is delivered anywhere in Kenya. For the same KSh 71,000 you could choose the flat 27-inch LG 27UP850K-W instead, while the 32-inch LG 32SR85U-W with webOS costs KSh 79,000.
Should I get the LG 34U640B-B or a 27-inch 4K monitor like the LG 27UP850K-W?
Choose the LG 34U640B-B for width, speed and multitasking, and the LG 27UP850K-W for pixel density and colour accuracy. Both cost KSh 71,000. This curved model shows 3440 x 1440 pixels at up to 144Hz on a high-contrast VA panel rated 4000:1. The 27UP850K-W shows 3840 x 2160 at 60Hz, covers 95% DCI-P3 and charges laptops at 90W against 65W here. Spreadsheet users, traders and PC gamers lean toward the ultrawide; photographers and print designers lean toward the flat 4K screen.
How does the LG 34U640B-B help with multitasking?
The LG 34U640B-B shows two full-size windows side by side on one 34-inch screen, with no bezel in the middle. Its 3440-pixel width fits a browser beside a spreadsheet, or code beside a live preview, both at readable sizes. The built-in KVM switch lets one keyboard and mouse control two computers connected to the monitor, so you stop reaching across the desk. Accountants, programmers and dispatch teams use this to keep a company laptop and a personal PC working side by side all day.
Can the LG 34U640B-B run on a UPS during KPLC power cuts?
Yes, the LG 34U640B-B runs from an external adapter rated 100-240V at 50/60Hz, so it works on Kenya's 240V mains and on a standard UPS. LG rates the adapter's output at 140W, the figure to add to your computer's draw when sizing backup power. During a KPLC outage, a UPS keeps the screen alive long enough to save documents and shut down properly. Customers in Westlands and Upper Hill offices tell us they pair monitors this size with a UPS for exactly that reason.
Is the LG 34U640B-B good for gaming on a PC or PlayStation 5?
The LG 34U640B-B suits PC gaming, with a 144Hz refresh rate, AMD FreeSync and 5ms grey-to-grey response. FreeSync matches the screen's refresh to the graphics card's frame rate, which removes tearing in fast scenes. PC racing and open-world games that support 21:9 fill the full width for a wider field of view. A PlayStation 5 or Xbox works over HDMI, but consoles output a 16:9 picture, so expect black bars on both sides of the screen during console play.
Who should buy the LG 34U640B-B and who should skip it?
Buy the LG 34U640B-B if you juggle many windows, trade, code, edit video or game on a PC. Skip it if colour-accurate photo or print work is your main job; the LG 27UP850K-W covers 95% DCI-P3 at the same price. Skip it too if you want streaming apps without a computer, where the LG 32SR85U-W with webOS fits better. Traders who need an even wider canvas can step up to the 49-inch LG 49U950A-W at KSh 185,000, also in stock at Mascom International.
Does the LG 34U640B-B support HDR, and how accurate are its colours?
The LG 34U640B-B supports HDR10 and covers up to 99% of the sRGB colour range, the standard used by most websites, apps and social media. That means web pages, presentations and online video look as their makers intended. Typical brightness is 300 cd/m², comfortable in indoor offices away from direct sun. Its VA panel's 4000:1 contrast gives deep blacks in dark films and night scenes in games. For cinema-grade colour grading in the wider DCI-P3 range, a dedicated 4K colour monitor serves better.
Will the LG 34U640B-B fit on my desk, and can I wall-mount it?
The LG 34U640B-B measures 809.1 mm wide and 220 mm deep with its stand, so plan for a desk wider than 81 cm. Height adjusts by 80 mm, and tilt runs from -5 to 15 degrees, letting you set the top edge at eye level. A 100 x 100 mm VESA pattern fits standard wall brackets and monitor arms, which frees desk space in a small apartment or a shared office. It weighs 7.7 kg with the stand and 5.6 kg without it.
