5 Best Monitor Backlights for Ultrawide Monitors of 2026
Five screen-sync backlight kits for 34 inch 21:9 monitors, compared on coverage, curved-screen fit, power, and the software each one runs on.
By Ethan Cole
Updated October 30, 2026
A 34 inch ultrawide is about 31 inches wide and 13 inches tall, so its outer edge runs about 7.4 feet, and most of that length is along the top and bottom. A kit cut for a 27 inch 16:9 screen will leave the ends bare. This guide covers five kits whose sellers sell them for 34 inch screens, all of which follow the picture through software on your computer.
The field is small. Several strips are sold in 34 inch versions, but only five came from brands with at least 20 Amazon ratings, and four of those ratings are shared with the brand’s smaller sizes. For 24 to 32 inch screens, see our main guide to the best monitor backlights.

Top 3 Monitor Backlights for Ultrawide Monitors Reviewed
#1 wacuaao RGB Monitor Backlight for 34 Inch Ultrawide Monitors: Best Overall
Why We Picked It
This is the one kit here built only for 34 inch 21:9 screens rather than stretched from a 24 to 34 inch range. wacuaao says the strip lengths are worked out for the ultrawide shape, it covers four sides, and the strip flexes to follow a curved screen. It has a WikiHomeLED Score of 81, from 4.3 stars on about 100 ratings at the time of review. Those ratings are shared across wacuaao’s 24, 27, 32, and 34 inch kits.
Long strips draw more power, and wacuaao feeds this one from two USB plugs, which it says prevents the dimming and flicker a single port can cause. Besides screen sync it has rainbow effects, static colors, and a music mode.
Key Specifications
- Size: 34 inch 21:9 ultrawide, curved screens listed
- Coverage: four sides
- Power: dual USB
- Sync: requires PC software (wacuaao’s other sizes use Skydimo)
- Modes: screen sync, music, dynamic rainbow, static color
| Pros | Cons |
|---|---|
|
|
Things to Consider
wacuaao’s 24 and 27 inch listings name Skydimo on Windows 10 or later and macOS 13 or later and say the kits do not work directly with consoles or smart TVs. The 34 inch listing only says it requires PC software, so expect the same, but confirm Mac support with the seller if that matters.
Best For
Owners of a 34 inch 21:9 ultrawide, flat or curved, who want four-sided coverage from a kit sized for that screen.
Skip It If
You have a 38 or 49 inch super ultrawide, or you have only one free USB port.

#2 Govee Gaming Light for Monitor G1: Most Buyer Feedback
Why We Picked It
The Govee G1 is sold for 27 to 34 inch monitors with curved screens listed, and it has the most ratings of any kit in this guide: 4.2 stars on more than 800 at the time of review. It reads the screen through Govee Desktop software and uses the Govee Home app for scenes and music modes.
We rank it second here, not first, because it is a single 5.9 ft strip meant to fit the whole 27 to 34 inch range. On a 34 inch ultrawide, whose edge runs about 7.4 feet, it will sit farther in from the edge than a strip cut for that screen. Govee says it covers all four sides.
Key Specifications
- Strip length: 5.9 ft, listed for 27 to 34 inch monitors
- Curved screens: listed
- Sync: Govee Desktop software (VibraMatch)
- Control: Govee Home app, 123 scene modes, 11 music modes listed
- Works with: Razer Chroma, other Govee gaming lights
| Pros | Cons |
|---|---|
|
|
Things to Consider
Some copy-protected streaming video cannot be read by the software, Govee notes, so the lights may not follow it. Like every kit here, it follows the PC, not a console.
Best For
PC users who value a long rating history and already use Govee or Razer lighting.
Skip It If
You want the glow to reach the far ends of a 34 inch screen, or you use a Mac.

#3 Fiotura G100 Monitor Backlight (34 inch): Skydimo on PC or Mac
Why We Picked It
Fiotura’s G100 is sold in sizes up to 34 inch, and this version’s listing says it fits 24 to 34 inch screens. It runs on Skydimo software on PC or Mac, with screen sync and music modes. The Fiotura line has 3.7 stars on about 190 ratings at the time of review, pooled across its sizes.
Setup is the same as other Skydimo kits: install the software, plug the strip’s USB into the computer, and it is detected. That makes it the best-documented Mac option in this guide after wacuaao’s smaller kits.
Key Specifications
- Size: 34 inch version, listed for 24 to 34 inch screens
- Sync: Skydimo software
- Computers: PC and Mac
- Power: USB from the computer
- Modes: screen sync, music
| Pros | Cons |
|---|---|
|
|
Things to Consider
Fiotura notes some copy-protected streaming content will not sync. Read recent reviews for the 34 inch size specifically, since the pooled rating mixes in the smaller strips.
Best For
Mac users with a 34 inch ultrawide who want a kit that names macOS support.
Skip It If
You want a top-rated kit; the wacuaao and Govee options have stronger ratings.

How to Choose Monitor Backlights for Ultrawide Monitors
Strip Length Matters More on an Ultrawide
A 34 inch 21:9 screen is about 31 by 13 inches, so its edge is roughly 7.4 feet, with long top and bottom runs and short sides. Kits sold for a range like 27 to 34 inch use one strip length for every size, so on an ultrawide they sit farther in. A kit cut for 34 inch, like the wacuaao, reaches closer to the ends.
Curved Screens
Most strips are flexible, but only some sellers list curved screens. wacuaao and Govee both do. On a tight curve, stick the strip a little in from the edge so it lies flat on the back panel.
Power for Long Strips
More LEDs need more current. wacuaao and Soleil both use two USB plugs. If a single-USB strip looks dim or flickers at full brightness, try a powered USB hub.
Software and Operating System
All five kits follow the screen through a program on your computer, not a camera. Govee uses Govee Desktop, Fiotura and Soleil use Skydimo, and RZJSKJZM uses SyncLight. None of them will follow a console plugged into the monitor.
Super Ultrawide Screens
For 38 and 49 inch screens we found kits from VELATEMOR, Yunir, and Zunate, but none had ratings yet, so we left them out. Check back as they collect reviews.
How We Evaluate Monitor Backlights for Ultrawide Monitors
We rank kits with the WikiHomeLED Score, which combines Amazon rating, rating volume, and listing completeness on the same scale for every product; the method is on our How We Review page. We did not install these kits ourselves; features come from each seller’s listing at the time of review. To be included, a kit had to be sold for 34 inch screens and come from a listing family with at least 20 ratings. The DS Gaming Monitor Light was left out because its title says 27 to 34 inch while its listing says 27 to 32 inch. A 34 inch Skydimo kit from hnlife and a ZIWJGPCCV kit had fewer than 20 ratings. Ratings shared across sizes are marked as pooled.
Frequently Asked Questions
Will a 27 inch monitor backlight fit a 34 inch ultrawide?
It will stick on, but it will not reach the ends. A 34 inch ultrawide is about 31 inches wide, compared with about 23.5 inches for a 27 inch 16:9 monitor, so a strip cut for 27 inch leaves several inches bare on each side.
Do these kits work on curved monitors?
wacuaao and Govee list curved screens. The strips are flexible, so others usually fit too, but stick them on the flatter part of the back panel and check the seller’s photos.
Can I use a monitor backlight on a 49 inch super ultrawide?
We found 49 inch kits, but none had ratings at the time of review, so we did not include them. A 34 inch kit will not cover a 49 inch screen.
Will the lights follow my console on an ultrawide?
No. All five kits read the screen through software on a PC or Mac, so a console plugged straight into the monitor bypasses them.
Final Verdict
The wacuaao kit is the only one here cut for the 34 inch 21:9 shape, with four sides, curved-screen fit, and two USB plugs, and its pooled rating is the best in the group. The Govee G1 has far more ratings but uses one strip length for 27 to 34 inch screens. On a Mac, the Fiotura G100 names macOS support most clearly.
