Dell Latitude 5520 — 15.6" 4K UHD with NVIDIA MX450 Graphics
A professionally tested and graded 15.6-inch business laptop built around Intel’s 11th Generation Core i7-1185G7 with 16GB of DDR4 memory, a 256GB NVMe SSD and dedicated NVIDIA GeForce MX450 graphics, running Windows 11 Pro. It carries a 4K UHD 400-nit ComfortView Plus display and a full-size keyboard with numeric keypad, backed by a 12-month Reboot IT warranty with free standard AU shipping.
Please read before ordering — display condition
This particular unit has a faint green tint visible on the screen. It is most noticeable on white or light-grey backgrounds, such as a blank document or a plain web page. The display is fully functional at its native 4K resolution and the panel is not cracked, but the colour is not neutral.
We have priced and graded this laptop with that in mind, and we would rather tell you now than have it arrive as a surprise. If you need colour-accurate work — photo editing, print, video grading, design sign-off — this is not the right machine for you. If you mainly work in documents, spreadsheets, code, email and browsers, or you plan to run it on an external monitor, it will not get in your way.
Key Benefits
-
Dedicated NVIDIA GeForce MX450 graphics: A discrete GPU with its own memory, sitting well above the integrated graphics in a typical business laptop. It accelerates photo work, CAD viewing, light 3D, video playback and GPU-aware applications, and drives multiple external displays comfortably.
-
15.6" 4K UHD at 400 nits: A 3840×2160 panel with four times the pixels of a Full HD screen, at 400 nits with ComfortView Plus hardware low-blue-light. Text is exceptionally sharp and you can fit far more on screen at once. Please read the display condition note above.
-
11th Gen Intel Core i7-1185G7: A 4-core, 8-thread processor with 12MB cache boosting to 4.8GHz — the top i7 in this Latitude generation, and noticeably quicker than the i5 configurations.
-
A free memory slot: 16GB is fitted in a single SODIMM with the second slot empty. Adding a matching 16GB module gives 32GB in dual channel — and dual channel matters more here than usual, because both the MX450 and a 4K panel benefit from the extra memory bandwidth.
-
Full-size keyboard with numeric keypad and Windows Hello: A 99-key backlit layout with a dedicated number pad, plus an infrared camera with ExpressSign-In for face recognition sign-on.
-
12-month warranty & free AU shipping: Every unit is tested, graded and covered by a 12-month Reboot IT warranty, with free standard shipping anywhere in Australia.
Performance In Use
The i7-1185G7 is the fastest processor Dell offered in this Latitude generation — four cores and eight threads with a 4.8GHz boost and 12MB of cache. Paired with 16GB of memory and NVMe storage it handles a heavy working day without complaint: a full inbox, large spreadsheets, a browser stacked with tabs, and a video call all at once.
The discrete MX450 is what separates this from an ordinary business laptop. Integrated graphics are fine for documents but stall on anything that actually asks for a GPU; a dedicated card with its own memory makes photo editing, CAD model viewing, light 3D work and GPU-accelerated applications genuinely usable. It also drives external monitors without stealing system memory to do it.
The 4K panel gives you real estate. At 3840×2160 on a 15.6-inch screen you can work two full documents side by side at readable sizes, or keep a spreadsheet and a reference window open together without either being cramped. Combined with the numeric keypad, this suits data-heavy and analytical work particularly well — subject to the display condition noted above.

Frequently Asked Questions
What exactly is wrong with the screen?
There is a faint green tint across the display, most visible on white or light backgrounds. It does not flicker, there are no cracks, dead pixels or backlight bleed, and the panel runs at its full native 3840×2160 resolution. It is a colour-cast fault, not a structural one. If you connect an external monitor, that display is unaffected.
Can the tint be fixed?
It is a panel-level fault, so software colour calibration will reduce but not eliminate it. A replacement 4K panel would resolve it entirely, and we are happy to quote for that if you would prefer a clean screen — just ask before ordering.
Is this laptop new or refurbished?
It is a professionally refurbished business laptop. Each unit is inspected, tested, cleaned and graded by our Melbourne team before it ships.
What is the MX450 good for?
The NVIDIA GeForce MX450 is a dedicated graphics card with its own memory. It comfortably outpaces integrated graphics for photo editing, CAD model viewing, light 3D work, video playback and GPU-accelerated applications, and drives external monitors without borrowing system memory. It is not a gaming card.
Can I upgrade the memory?
Yes. This unit has a single 16GB DDR4 SODIMM with the second slot empty, so adding one matching module gives 32GB in dual channel without removing anything. The platform supports up to 64GB. Dual channel is particularly worthwhile here, since both the MX450 and the 4K panel benefit from the extra bandwidth.
Does it have a fingerprint or smart card reader?
No. This unit was factory-configured with the plain palmrest — no fingerprint reader, no smart card reader and no NFC. Windows Hello face sign-in via the infrared camera is available instead.
Does it support Intel vPro?
No. This particular unit was configured by Dell with Intel management disabled, so it suits standalone use rather than a vPro-managed corporate fleet.
Does it have mobile broadband or a SIM slot?
No. This unit was built with a wireless-LAN-only lid and no mobile broadband card, so LTE cannot be fitted. It connects via Wi-Fi 6, Bluetooth or a wired dock.
Does it come with a charger?
Yes, a compatible 90W USB-C power adapter is included so the laptop is ready to use on arrival.
How much does shipping cost?
This laptop qualifies for free standard AU shipping, delivered anywhere in Australia at no extra cost.
What warranty is included?
Every unit is covered by a 12-month Reboot IT warranty, with an additional 30-day battery warranty for peace of mind. The display tint described above is a known and disclosed condition of this unit and is not itself a warranty fault.
