Lenovo IdeaCentre AIO 27 specs, features and buying guide
The Lenovo IdeaCentre AIO 27IRH9 is a 27-inch all-in-one desktop: a full-HD IPS screen at 100 Hz, a 13th Gen Intel Core processor, DDR5 memory in two upgradeable slots and a 5 MP camera with a privacy shutter. One power cable and a keyboard is the whole setup, which is the point of an all-in-one.
The display is 27 inches at 1920 x 1080 on an IPS panel with an anti-glare finish, 300 nits of brightness, a 100 Hz refresh rate and 99% sRGB coverage. Lenovo also sells QHD versions of the same family at 2560 x 1440 and 350 nits, and touch versions with 10-point multi-touch, so the panel is one thing to confirm against the exact model.
Inside, Lenovo lists processors from the Core i3-1315U up to the Core i9-13900H, DDR5-5200 memory across two SO-DIMM slots for up to 32 GB, and a single M.2 2280 SSD on PCIe 4.0 x4 up to 1 TB. Graphics are integrated Intel UHD or Iris Xe, and there is no discrete GPU option in the specifications Lenovo publishes.
Around the back and sides sit one USB-A port at 10 Gbps, two at USB 2.0, a USB-C port at 10 Gbps, HDMI in, HDMI out, gigabit Ethernet and a headphone jack. The USB-C port is data transfer only, and the stand tilts from -5 to +15 degrees with no height adjustment.
What to check before you buy the IdeaCentre AIO 27
Lenovo sells 27-inch IdeaCentre all-in-ones in more than one family, and the specification above is the Intel 27IRH9 — the one whose full data sheet Lenovo publishes. Before ordering, match the model number in the listing against 27IRH9. If the listing names a different family, the processor list, panel figures and port layout here may not apply.
Within the family, three choices matter most: full HD or QHD, touch or non-touch, and whether a keyboard and mouse are included. Lenovo lists keyboard and mouse as configuration options and some models ship without either, so a desktop that looks cheaper may simply have no input devices in the box.

Key features explained
A 100 Hz panel on a desktop
Most all-in-ones settle for 60 Hz. Lenovo lists 100 Hz here, which makes scrolling and window movement look smoother rather than changing what the screen can display. It does not make this a gaming machine: the graphics are integrated, and the panel is 300 nits at 99% sRGB, which is an office and photo-hobby panel rather than a reference display.
Two SO-DIMM slots and DDR5
Memory is DDR5-5200 across two SO-DIMM slots, up to 32 GB. That is unusual for an all-in-one at this size, where memory is often soldered. It means a 16 GB machine can be taken further later with a pair of modules, and it also means the memory runs in dual channel when both slots are populated.
HDMI in as well as HDMI out
The HDMI input is the port that separates this from a monitor with a PC bolted on. It lets a games console, a streaming stick or a work laptop use the 27-inch panel, and Lenovo lists HDMI 1.4 for that input. The HDMI output is 2.1 TMDS, so the desktop can drive an external screen as well.
A 5 MP camera with a shutter latch
The webcam is 5 MP, with a 5 MP IR option on models that support Windows Hello face sign-in, and both carry a shutter latch. A 5 MP sensor is a step above the 1080p cameras most desktops still ship, which matters if you spend the day on video calls. The dual-microphone array is separate from the speakers.
27 inches at 1920 x 1080, and what that density means
A 27-inch 1920 x 1080 panel works out to roughly 82 pixels per inch. Text is legible and video looks fine, but close-up work shows the pixel structure more than a smaller laptop screen would, and split-screen use at this size is tighter than the diagonal suggests. Lenovo publishes that number honestly, and it is the reason a QHD version of the same family exists.
The QHD option is 2560 x 1440 at 350 nits on the same 27-inch diagonal. That is the version to choose if you read a lot of text, work with two windows side by side, or edit photos. The trade is a slightly heavier machine — 7.51 kg against 7.1 kg — and a higher price for the same processor options.
The ports, and the one that is data-only
Rear ports are one USB-A at 10 Gbps, two USB-A at USB 2.0, HDMI in, HDMI out, gigabit Ethernet and the power input. The USB-C port sits on the left at 10 Gbps and is data transfer only, so it cannot drive a display and cannot charge anything.
That is worth saying plainly because USB-C is often assumed to mean video out. On this desktop, an external monitor goes on the HDMI 2.1 TMDS output, and the Ethernet port means a wired connection is available without a dongle. Lenovo lists a 90 W or 135 W autosensing adapter depending on the configuration.
Tilt only, and where the desk should sit
The stand tilts from -5 to +15 degrees. There is no height adjustment and no swivel, which is the main ergonomic limit of this design: the bottom of the screen sits at a fixed height, so the desk and chair have to do the work that a height-adjustable stand would otherwise do.
The footprint is roughly 612 x 192 mm for the FHD model, and the whole thing weighs about 7.1 kg. Measure the desk depth before ordering, because a 27-inch all-in-one with a stand this deep takes more room than a monitor on an arm, and the panel sits closer to the wall than a tower-plus-monitor setup would.
Who should buy the IdeaCentre AIO 27, and who should skip it
Who should buy the IdeaCentre AIO 27
- You want one cable and a clean desk rather than a tower, a monitor and a tangle of leads.
- You want a 27-inch screen that a console or a work laptop can also use, through HDMI in.
- You want memory you can upgrade later: two DDR5 SO-DIMM slots up to 32 GB.
- You take a lot of video calls and want a 5 MP camera with a privacy shutter.
Who should skip it
- You need detailed text at 27 inches: a 1920 x 1080 panel at this size is about 82 ppi.
- You need a height-adjustable or swivelling stand — this one only tilts.
- You want USB-C video output or USB-C charging: that port is data only.
- You need a discrete GPU for gaming or 3D work: Lenovo lists integrated graphics only.

Buying the IdeaCentre AIO 27 in the US
Confirm the model number first, then the panel. Lenovo builds 27-inch IdeaCentre all-in-ones in more than one family, and this sheet documents the Intel 27IRH9. Within that family, decide between full HD and QHD before anything else: it is the choice you cannot change later, and at 27 inches it is the one you will notice every day.
Then check what is in the box. Lenovo lists keyboard and mouse as configuration options, so a desktop sold without them needs a set added to the total. If you want Windows Hello face sign-in, look for the 5 MP IR camera rather than the standard 5 MP module, since they are different configurations of the same chassis.
Frequently asked questions: IdeaCentre AIO 27
What processors does the IdeaCentre AIO 27 use?
Lenovo lists 13th Gen Intel Core chips from the Core i3-1315U through the Core i5-13420H and Core i7-13620H to the Core i9-13900H on the 27IRH9. The exact chip depends on the configuration.
Can you upgrade the memory and storage on the IdeaCentre AIO 27?
Yes for memory: there are two DDR5 SO-DIMM slots supporting up to 32 GB at DDR5-5200, so it is not soldered. Storage is a single M.2 2280 slot on PCIe 4.0 x4, up to 1 TB, so a larger drive replaces the original rather than adding to it.
Can the USB-C port on the IdeaCentre AIO 27 drive a monitor?
No. Lenovo lists the USB-C port at 10 Gbps for data transfer only. An external display goes on the HDMI 2.1 TMDS output, and the desktop also has an HDMI 1.4 input.
Does the IdeaCentre AIO 27 have a touchscreen?
On some models. Lenovo lists 10-point multi-touch as available on touch configurations of the 27IRH9, with non-touch panels on the others, so check the listing.
Is a keyboard and mouse included with the IdeaCentre AIO 27?
Lenovo lists wired or wireless keyboard and mouse sets on some models and configurations without them on others. It is not safe to assume either way, so confirm the box contents before ordering.
Can I use the IdeaCentre AIO 27 as a monitor for a console?
Yes. The HDMI 1.4 input lets another device use the 27-inch panel, so a console, a streaming stick or a laptop can drive the screen without going through Windows.
How heavy is the IdeaCentre AIO 27?
Around 7.1 kg for the full-HD models and around 7.51 kg for the QHD models, according to Lenovo. The stand tilts from -5 to +15 degrees and does not adjust for height.
Does the IdeaCentre AIO 27 have a privacy shutter on the camera?
Yes. Lenovo lists a camera shutter latch on both the 5 MP and the 5 MP IR camera options, so the lens can be covered when it is not in use.
