Certified Refurbished Dell UltraSharp U2312HM 23-Inch IPS Monitor
The certified refurbished Dell UltraSharp U2312HM is a 23-inch (58.4cm) professional IPS display with Full HD 1920x1080 resolution, an 8ms grey-to-grey response time, and connectivity covering DVI-D with HDCP, DisplayPort, and VGA. Because the Enhanced IPS (e-IPS) panel maintains consistent colours at up to 178 degrees horizontally and vertically, it suits tasks where accurate, stable visuals matter—design work, document editing, and extended multi-monitor setups. Full ergonomic adjustability including 130mm height adjustment, tilt, swivel, and 90-degree portrait pivot means this monitor adapts to the user rather than the other way around.
Ideal For
- Graphic designers and photo editors – sRGB-accurate IPS colour ensures images look consistent from any working angle
- Business and home office users – multi-window workflows benefit from the sharp Full HD canvas and full ergonomic stand range
- Multi-device setups – three input types (DVI-D, DisplayPort, VGA) and four USB 2.0 ports support simultaneous connections without a separate hub
- Wall and arm-mount installs – VESA 100x100mm compatibility frees desk space and enables flexible positioning
Key Features & Benefits
- Enhanced IPS Panel: Consistent colour and brightness from virtually any angle—unlike TN panels that shift colour off-axis, which means team reviews and side-by-side comparisons stay accurate
- 1920x1080 Full HD: Sufficient sharpness for spreadsheets, design tools, and video calls; remains the standard resolution for most office software in 2026
- Three Input Options: DVI-D with HDCP, DisplayPort, and VGA cover nearly every device from the last two decades, therefore reducing adapter requirements
- Integrated USB Hub: Four USB 2.0 downstream ports handle keyboards, mice, USB drives, and phone charging conveniently from the monitor itself
- ENERGY STAR Qualified: Typical 30W consumption and under 0.5W standby keep running costs low across years of daily use
Common Questions
Is the colour accuracy good enough for design work?
In our testing, the e-IPS panel covers sRGB reliably, which is sufficient for everyday graphic design, photo editing, and web content work. It is not a wide-gamut display, so professional print production requiring DCI-P3 coverage is better suited to a higher-spec panel. For the vast majority of design tasks, sRGB accuracy at this price point is genuinely useful.
How does a 2012-era monitor hold up in 2026?
Full HD 1080p remains the standard for most office software, video conferencing, and web browsing, so the resolution ceiling is not a limitation for everyday use. We routinely see these units performing well as primary or secondary displays; the IPS build quality and ergonomic range were above average at launch and remain so today.
How do I connect this to a modern laptop with USB-C or HDMI?
A USB-C to DisplayPort adapter or an HDMI-to-DVI adapter (both widely available) will connect modern laptops cleanly. DisplayPort delivers the best signal quality of the three available inputs.

Refurbished Computers - Cosmetic Grading Guide
Our supplier's refurbished hardware is typically graded either "Excellent" or "Good", however, some legacy products were graded under a letter grading system (A, B, C). Please find the definitions for each grade below and contact us if you're uncertain of a device's grade.
Used Smartphone / Refurbished Mobile Phones
"Excellent" Grade
Devices in this category appear like new, with very minor wear. Expect light or fine scratches on the screen that are shallow enough not to catch on a fingernail. The edge around the glass is virtually flawless, save for possible light scratching around the power port. The back plate may show light/fine scratches, including on the Apple logo, with any discoloration being minimal.
"Good" Grade
These devices are characterized by being fully tested and functional even if they have body scratches, minor paint chips, or a small hairline crack on the screen. Screens are free from dead pixels but may exhibit slight scratching from moderate use.
