LG UltraFine evo 32U990A Review: The First 6K with Thunderbolt 5

The verdict, up top

LG took a long time to return to the Mac monitor market. The old UltraFine 5K is a 2015 design Apple stopped selling years ago. The UltraFine evo 32U990A is what LG did with that time: the first 6K monitor with Thunderbolt 5, announced at CES 2025 and shipping since November 2025 at $1,999.

The panel is the same class as the Dell U3224KB, 6144 × 3456 at 224 PPI, with LG’s Nano IPS Black technology for deeper blacks and a wider gamut. Thunderbolt 5 makes it the only 6K that works natively with Thunderbolt 5 Macs, a list that now runs from the M4 Pro through the M5 Pro and M5 Max MacBook Pros to the M5 Pro Mac mini and the M5 Max and M5 Ultra Mac Studio.

At $1,999 it sits $700 above the ASUS PA32QCV, and that gap is hard to justify. Since launch, though, LG has run near-constant promotions, often bringing it down to around $1,299. At that price it is the 6K you can’t ignore.

What Thunderbolt 5 actually gets you

Every earlier 6K monitor used Thunderbolt 3 or 4 at 40 Gb/s, relying on DSC compression for the full picture. To be clear about what changes: 6K runs at 60 Hz on every Mac Apple sells, so Thunderbolt 5 does not buy a higher refresh rate. It buys bandwidth for everything else on the cable, plus a two-6K daisy-chain.

The 32U990A has two Thunderbolt 5 ports. The upstream port carries the 6K picture, data and 96W of charging over one 80 Gb/s cable. The downstream port can daisy-chain a second 6K 60 Hz display, which Thunderbolt 4 bandwidth cannot do: two 6K panels from one port on your Mac. Your Mac still has to support that many displays; check your chip in our external display support tool, and see the bandwidth maths in our cable bandwidth calculator.

The monitor uses Thunderbolt 5’s symmetric 80 Gb/s mode rather than the 120 Gb/s asymmetric mode. For a 6K 60 Hz panel that makes no practical difference.

The panel

“Nano IPS Black” combines two technologies. IPS Black adds a contrast layer that LG rates at 2,000:1, double standard IPS, so blacks look darker in a dim room instead of glowing grey. Independent labs measured it lower than claimed, around 1,500 to 1,720:1, which is still clearly better than typical IPS (full figures below). Nano IPS widens the gamut to 98% DCI-P3 and 99.5% Adobe RGB.

That Adobe RGB figure matters. The ASUS PA32QCV and Apple’s displays are P3 monitors, which is the right gamut for video and general creative work. If your work ends up in print or prepress, or your photography lives in Adobe RGB, this LG is the only 6K we cover that fully supports it.

Sharpness matches the Dell: 224 PPI, just above the 218 PPI target, rendered by macOS at a clean 2×. Text looks as crisp as a MacBook Pro’s built-in screen.

LG rates brightness at 450 nits typical with DisplayHDR 600; labs broadly confirm the SDR figure and exceed the HDR one. It is still mid-tier HDR. Real HDR grading needs the Mini-LED zones of a Studio Display XDR.

The coating is a light anti-glare, closer to semi-gloss than the ASUS’s heavy matte. Colours get a little extra pop, but you will see reflections from a window behind you. Kuycon sells both extremes, glossy glass on the G32P and heavy matte on the G32X, and the LG sits between them.

KVM and Mac software

The Auto KVM switches your keyboard and mouse between two connected computers automatically, and picture-by-picture and picture-in-picture modes show both at once. On the Dell, you pay $2,399 for a similar feature set.

LG has done its Mac homework. Studio Mode includes presets matched to macOS rendering, and the LG Switch app with M-Control lets your Mac’s brightness and volume keys control the monitor. It is a third-party app rather than native support, so it is less seamless than an Apple display. The weakest part of the experience is the on-screen menu, which runs vertically along the right edge and takes more clicks than it should.

Ports and charging

Beyond the two Thunderbolt 5 ports there is a full-size DisplayPort 2.1 input (better than the Dell’s Mini DisplayPort), an HDMI 2.1 input and two USB-C downstream ports at 15W each.

The hub is limited. There is no USB-A, so older receivers need adapters, and no Ethernet; the Dell includes 2.5GbE and four USB-A ports. If you use several wired peripherals, budget for a small dock.

Charging is 96W, the same as the ASUS and the regular Studio Display but short of the 140W from the Dell and Studio Display XDR. That is fine for a 14-inch MacBook Pro; a 16-inch M4 Max or M5 Max will slowly drain under heavy sustained load.

The stand

This is the biggest weakness. The L-shaped stand looks clean and keeps the desk open, but it travels only 60 mm vertically, against 130 mm on the ASUS and 160 mm on the Dell. It tilts from −5° to +20° and pivots 90° for portrait, but it does not swivel. Taller users will want a monitor arm on the 100 × 100 VESA mount. The panel weighs about 6 kg without the stand, so any mid-range arm can hold it.

Who should buy it

• Owners of Thunderbolt 5 Macs who want to use those ports
• Photographers and print designers who need 99.5% Adobe RGB
• Anyone planning a dual-6K desk via daisy-chain without a dock
• Two-computer desks that will use the Auto KVM daily
• Anyone who finds it near the $1,299 sale price

Who should buy something else

• At full price against an ASUS PA32QCV at $1,299, the ASUS is the smarter buy, with Calman Verified calibration and a much better stand
• 16-inch Max MacBook Pro owners who want full-speed charging should look at the Dell U3224KB
• HDR professionals belong on the Studio Display XDR or a used Pro Display XDR
• If you want a built-in webcam and conferencing features, the Dell is the only 6K with them
• If you want glass rather than any coating, the Kuycon G32P puts a similar Nano IPS Black-class panel behind laminated glass

The bottom line

The UltraFine evo 32U990A is the most future-ready 6K monitor you can buy: the only one with Thunderbolt 5, with genuine Adobe RGB coverage and a panel with deeper blacks than standard IPS. It beats the ASUS on connectivity and panel technology.

It is not perfect. The stand is underwhelming, the hub lacks USB-A and Ethernet, and LG’s software and menus feel dated. A monitor arm and a small dock solve most of that.

Price decides whether it is worth buying. At $1,999, we recommend the ASUS PA32QCV for most people. When the LG drops to around $1,299, as it often does on Amazon, it becomes one of the best values in 6K.
