Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

Problem with an order right now? Write to [email protected], [email protected] or [email protected] — answered the same business day. The letter also lists our group and store owners' contacts.

The EIZO ColorEdge CG3100X is a professional 30.5-inch (77.5 cm) DCI 4K monitor with a native 17:9 aspect ratio and 4096 × 2160 resolution. It is designed for film post-production, color grading and image editing, offering HDR-ready presets (PQ and HLG), a wide color gamut, a 24-bit 3D LUT and an integrated calibration sensor for stable, precise color reproduction. The monitor supports single-cable USB-C connectivity with power delivery, a DisplayPort and an HDMI input capable of handling uncompressed 12-bit DCI 4K (4:4:4) signals, plus network and USB hub options for professional workflows.

Advantages

The CG3100X provides accurate, high-contrast color reproduction across common color spaces including Rec709, DCI-P3, Rec2020 and AdobeRGB, with hardware support via a 24-bit 3D LUT and Digital Uniformity Equalizer for even luminance. Its HDR functionality (PQ and HLG presets) and up to 500 cd/m² peak brightness allow integration into modern HDR pipelines. Connectivity includes USB-C with up to 94 W power delivery, DisplayPort and HDMI with FRL for 12-bit 4:4:4 DCI 4K, an RJ45 LAN port and a USB hub, while the built-in calibration sensor enables automatic self-calibration to maintain consistent results.

Key specifications

How to use

Place the monitor on a stable desk or mount it using the VESA interface. Connect your computer via USB-C to transmit video, data and power over a single cable, or use DisplayPort/HDMI depending on source compatibility and desired bit depth. Use the integrated calibration sensor and the provided software or monitor controls to perform automatic self-calibration at regular intervals to ensure consistent color accuracy. Adjust height and ergonomics as needed for a comfortable working position.

Recommendations

For color-critical work, allow the monitor to warm up for at least 30 minutes before starting grading or final reviews, and schedule regular automatic calibrations. Use HDMI with FRL when working in HDMI-based DCI 4K production environments that require uncompressed 12-bit 4:4:4 signals; use USB-C for single-cable laptop setups with power delivery.
