LG’s 38-inch curved UltraWide monitors are some of the most popular “one screen to replace two” options for people who work on a laptop all day. They are big, bright and wide enough to keep three full-size windows side by side. They are also expensive, physically huge and not the right tool for everyone. This guide explains what you get with a 38-inch 21:9 panel, who benefits most, and what to check before you buy.
Check the exact model number. LG sells several 38-inch UltraWide models over the years, aimed at office work, creative work or gaming, and they differ in refresh rate, HDR support and USB-C/Thunderbolt power delivery. The flagship productivity model, the 38WN95C-W, is the one most reviews refer to: 3440×1440 Nano IPS panel, up to 144 Hz, VESA DisplayHDR 600 and a Thunderbolt 3 port with up to 94 W of laptop charging. Always confirm the specs on the listing you are buying from.
What 38 inches at 21:9 really means
A 38-inch UltraWide with 3440×1440 resolution has a panel about 35 inches (89 cm) wide and 14.7 inches (37 cm) tall — narrower than two 24-inch monitors side by side, but taller than either of them and with no bezel in the middle. In practice that means:
- Three comfortable columns: for example, a code editor, a browser and a terminal, each around 1,150 pixels wide.
- About 98 pixels per inch: text is sharp at normal distances with 100% scaling on Windows, but noticeably less crisp than a 4K 27-inch monitor or a MacBook’s own display. macOS users who are used to Retina text sometimes find this the biggest compromise.
- A panel roughly 90 cm (35 in) wide: you need a desk at least 120 cm wide and ideally 70 cm or more deep so you can sit far enough back.
Who it is best for
Laptop users who want a single-cable desk
On models with Thunderbolt or USB-C power delivery, one cable carries the picture, charges the laptop and connects the monitor’s built-in USB ports. Plug in when you sit down, unplug when you leave. It is the main reason these monitors are so common in developer and remote-work setups. Check that the wattage is enough for your laptop: 90 W-class charging covers most 13–14-inch laptops, while 16-inch performance laptops may still charge slowly under heavy load.
Video editors, music producers and spreadsheet power users
Anything organized along a horizontal timeline benefits from the extra width: more of the edit visible at once, less zooming and scrolling. Nano IPS panels in LG’s premium models cover a wide color gamut, which makes them good for photo and video work, but “wide gamut” is not the same as “calibrated”. If you deliver color-critical work, plan to calibrate with a colorimeter and use the correct color profile rather than relying on the default wide-gamut mode.
People who game after work
High-refresh versions offer smooth motion and adaptive sync, and many racing, flight and adventure games support 21:9. Driving 3440×1440 at high frame rates requires a capable graphics card, so budget for that if gaming is a priority.
Who should skip it
- You present or share your screen constantly. Sharing an ultrawide produces a thin strip for viewers; a normal 16:9 monitor (or two) is easier.
- You value text sharpness above all. A 27-inch 4K or 5K monitor offers far higher pixel density.
- Your desk is shallow or narrow. Sitting too close to a 38-inch curve means turning your head to read the edges.
- You work in CAD or architecture. The curve can make straight lines look bowed; a flat display is more predictable.
Getting the most out of it
Split the screen into zones
LG’s OnScreen Control software can divide the display into preset layouts. Many people prefer dedicated window managers: Microsoft PowerToys FancyZones on Windows (free), and apps such as Rectangle or Magnet on macOS. Create one layout for focused work (a large center window with a narrow column on each side) and one for multitasking (three equal columns).
Use the right refresh rate and cable
After connecting, open your display settings and confirm the monitor is running at its native 3440×1440 and the highest refresh rate your cable and computer support. A low-quality USB-C cable can silently limit the refresh rate or disable charging; use the cable that came in the box or a certified Thunderbolt cable.
Consider a monitor arm
The included stands on large ultrawides tend to be deep. A VESA monitor arm rated for the monitor’s weight frees desk space and makes it easier to set the top of the screen at eye level. Heavy 38-inch panels need a sturdy arm, so check the weight capacity carefully.
Alternatives worth considering
| Option | Why pick it instead |
|---|---|
| 34-inch 3440×1440 ultrawide | Same resolution, sharper text (~110 PPI), smaller footprint and usually cheaper |
| 40-inch 5K2K ultrawide (5120×2160) | Much sharper text and more space, at a higher price and with heavier GPU demands |
| Two 27-inch QHD monitors | More total pixels for the money and easier screen sharing (see our ultrawide vs. dual monitors guide) |
| 27-inch 4K or 5K monitor | Best text clarity for reading and coding, especially on macOS |
Bottom line
A 38-inch LG UltraWide is a luxurious centerpiece for a laptop-based desk: huge working area, one-cable convenience on Thunderbolt/USB-C models and enough speed on high-refresh versions for gaming. Buy it if you work in wide timelines or want a clean single-screen setup and have the desk to match. If sharp text or frequent screen sharing matters more, a 34-inch ultrawide, a 4K 27-inch display or a dual-monitor setup will serve you better.
