27" 4K UHD IPSUSB-C · 100W PDRJ45 + USB hub155mm lift · pivot
The Lenovo ThinkVision T27UD-40 is a 27-inch 4K UHD (3840 x 2160) IPS monitor with a USB-C connection that delivers 4K video, 10Gbps USB data, Gigabit Ethernet and up to 100W of laptop charging over one cable. It is built for business users who want very sharp text and a clean, single-cable desk.
At 163 PPI, 4K at 27" makes documents, spreadsheets and photos look print-sharp. The panel shows 1.07 billion colours (10-bit via 8-bit + FRC) with 99% sRGB, supports HDR10 and carries TÜV Eye Comfort, hardware Low Blue Light and Eyesafe 2.0 certifications.
Before you order: Refresh rate is 60Hz. An HDMI cable is not included (DisplayPort and USB-C cables are). For video over USB-C, the laptop's port must support DisplayPort Alt Mode.

Frequently Asked Questions
Can a MacBook use it with one cable?
Yes. MacBooks support DisplayPort Alt Mode over USB-C/Thunderbolt, so one cable provides 4K video, USB, Ethernet and up to 100W charging.
Is 4K at 27" worth it for office work?
If you read a lot of text or work with detailed drawings, yes — text is noticeably crisper than on QHD, at 150% scaling.
Do I need an HDMI cable?
Only if you connect a device via HDMI. DisplayPort and USB-C cables are included.
