| Microsoft Surface Laptop Ultra RTX Spark Review - The 2000-nits Mini-LED panel is a problem |
When Microsoft announced the Surface Laptop Ultra with NVIDIA's groundbreaking RTX Spark N1X chip, the tech world collectively gasped. This was supposed to be the laptop that would finally dethrone Apple's MacBook Pro as the ultimate creative powerhouse. With up to 128GB of unified memory, a 20-core ARM CPU, and a 6144-core Blackwell GPU, the specs sheet reads like a dream.
But after spending extensive time with the $4,299 review unit (20-core N1X, 64GB RAM, 1TB SSD), I'm here to tell you that dreams don't always match reality. And the culprit? A display that's simultaneously the brightest on the market and one of the most disappointing premium panels I've tested this year.
The Good: Performance That Actually Delivers
Let's start with what works, because there's genuinely a lot to love here.
The NVIDIA RTX Spark N1X is a revelation. In our Cinebench 2024 multi-core tests, the Surface Laptop Ultra scored 1,682 points—right in line with the Asus ProArt P16 that also runs the same chip. More importantly, performance remained stable under sustained workloads. Unlike many Windows laptops that throttle the moment you unplug them, this Surface maintained 1,679 points on battery power. That's less than a 1% drop.
For content creators running local AI models, the unified memory architecture is a game-changer. You can allocate up to 64GB of VRAM for GPU tasks, meaning you can run massive language models or handle 8K video timelines without breaking a sweat.
The build quality is equally impressive. Microsoft's metal chassis feels premium, the haptic trackpad works beautifully, and the backlit keyboard—while lacking a bit of travel—is comfortable for extended typing sessions. The magnetic USB-C connector, which Microsoft is clearly proud of, works as advertised, though it does block the adjacent USB-A port when connected.

Here's where things fall apart.
The 15-inch Mini-LED panel hits an incredible 2,034 nits peak HDR brightness—the brightest we've ever measured in a laptop. Colors are accurate (99.6% P3 coverage), and the 3:2 aspect ratio at 3270 x 2180 pixels offers a productivity-friendly canvas.
But brightness alone doesn't make a great display. And the Surface Laptop Ultra's panel has three major problems:
1. No Local Dimming
This is inexplicable. Mini-LED technology's entire purpose is local dimming—the ability to selectively dim zones of the backlight for deeper blacks. Yet Microsoft hasn't implemented it. The result? A black level of 0.61 cd/m², which is essentially IPS-level performance. Dark scenes in movies look washed out, and the contrast ratio of 1,736:1 is embarrassing for a premium laptop in 2026.
2. Ghosting Issues
The panel uses a slow IPS layer combined with the Mini-LED backlight. Response times measured 57.2ms (black to white) and 51ms (grey to grey). Even with the 120Hz refresh rate, motion looks smeared. Gamers and video editors will notice this immediately.
3. PWM Flickering
At 4,650Hz with 100% amplitude, sensitive users may experience eye strain during extended use.
When you compare this to the Asus ProArt P16's 4K Tandem OLED, which delivers 1,644 nits HDR brightness with perfect blacks and 0.27ms response times, the Surface's display feels like a compromise. Even the MacBook Pro's Mini-LED implementation—which actually uses local dimming—offers a superior viewing experience.

The Surface Laptop Ultra weighs 2kg and measures 18mm thick. Compared to the 13mm, 1.79kg Asus ProArt P16, it feels bulky—especially for a 15-inch laptop competing against 16-inch rivals.
Port selection is decent:
- 3x USB4 (40Gbps)
- 1x USB-A
- 1x HDMI
- SD card reader (but no SD-Express support)
- 3.5mm audio jack
- Magnetic USB-C charging
The lack of SD-Express is a notable omission for photographers, especially when competitors like the ProArt P16 include it. And the single M.2 SSD slot limits future upgrades.
The 1080p webcam is adequate but unremarkable. The quad-speaker system sounds good for a laptop, and Wi-Fi 7 connectivity proved fast and reliable in our testing.
Battery Life and Thermals
The 92Wh battery delivers approximately 5-6 hours of mixed use—acceptable for a desktop replacement but not impressive. The cooling system handles the RTX Spark N1X well, with fan noise maxing out at 46.2 dB(A) under full load. That's audible but not distracting.

Software: The ARM Compatibility Elephant
Windows on ARM has come a long way, but it's not perfect. During testing, some games and legacy applications refused to launch. Microsoft deserves credit for clearly stating compatibility limitations in the official specifications, but buyers should verify their essential software works before committing.

How It Compares: Surface Laptop Ultra vs. Asus ProArt P16
| Feature | Surface Laptop Ultra | Asus ProArt P16 |
|---|---|---|
| Price (reviewed config) | $4,299 (64GB/1TB) | $6,999 (128GB/2TB) |
| Display | 15" Mini-LED, 120Hz, 2034 nits HDR | 16" 4K Tandem OLED, 120Hz, 1644 nits HDR |
| Local Dimming | ❌ No | N/A (OLED) |
| Response Time | 51-57ms | 0.27-0.43ms |
| Black Level | 0.61 cd/m² | Perfect blacks |
| Weight | 2.0 kg | 1.79 kg |
| Thickness | 18mm | 13mm |
| SD-Express | ❌ No | ✅ Yes |
| Webcam | 1080p | 1080p |
The ProArt P16 costs significantly more, but for content creators who prioritize display quality, it's the better investment. The Surface wins on price and build quality, but the display compromises are hard to swallow at this price point.

The Microsoft Surface Laptop Ultra is a frustrating product. The RTX Spark N1X delivers excellent, stable performance. The build quality is superb. The magnetic charging connector is genuinely innovative.
But a $4,299 laptop should not have a display that ghosts during motion, lacks local dimming despite using Mini-LED technology, and produces washed-out blacks. These aren't nitpicks—they're fundamental flaws that affect every aspect of the user experience.

Who Should Buy It?
Buy it if: You need maximum AI compute performance in a premium Windows laptop and display quality is secondary to raw processing power.
Skip it if: You're a content creator, videographer, or anyone who cares about display quality. The Asus ProArt P16 or MacBook Pro 16 offer vastly superior viewing experiences.
