A calibrated photo monitor is an essential part of any digital imaging workflow, but price and size can be deterrents. The Acer ConceptD CM2 CM2241W could be the simple solution for photographers - saving the need to buy a separate monitor calibrator.
We all know that the monitors in desktop computers and photo-editing laptops are usually the cheapest displays manufacturers can get away with. We also know that a calibrated monitor is essential for image editing, especially if you’re planning to make accurate prints. But then the inevitable questions about photo monitors are – does it have to be so big and do I really have to spend that much money? The answers are ‘no’ and ‘no’.
The good news is that the choice of more affordable photo monitors is on the increase and Acer is the latest arrival with its ConceptD CM2 series. The CM2241W is the 24-inch monitor and this display size strikes a good balance between something that’s big enough to be useful for applications such as image editing, but doesn’t take up a whole lot of space on your desk. The panel’s 16:10 aspect ratio helps here too, as it’s a bit taller than 16:9 and works well with images in the 3:2 aspect ratio, which is basically anything from a digital camera with either a full frame or APS-C sized sensor.
The resolution is Full HD (at 1920x1200 pixels so, to be precise, WUXGA), which might cause a raised eyebrow now that 4K displays are becoming so common, but for some applications you can, in fact, have too much resolution. It may sound contradictory, but in terms of evaluating fine detailing in a still image, less resolution can be better than more, especially at the smaller monitor sizes which result in very high pixels-per-inch (ppi) counts. The CM2241W is very much targeted at enthusiast-level photographers who simply don’t need a big 4K monitor.
The display is an IPS panel with LED backlighting, an area of 518.4x324.0 millimetres and the resolution gives 109ppi. It has 10-bit color processing, delivering a palette of 1.07 billion for smoother shading, color transitions and tonal gradations. The IPS (In-Plane Switching) technology enables a wide viewing angle of up to 178 degrees, both horizontally and vertically. The response time is 1.0ms VRB – which is very fast indeed and more than enough for video-editing applications – and the refresh rate is 75Hz. A light matte anti-glare coating helps reduce reflections and glare, but doesn’t eliminate the latter entirely.

Design & features
Externally, the CM2241W is very stylish looking with super-slim bezels, a gently rounded back casing, a silver tubular support arm, and a circular base with a timber-effect finish. Initially, the base looks like it might just be a bit too small, but it’s actually quite weighty and certainly stable enough. Monitor positioning adjustments are very easily applied, including swiveling through a full 360 degrees. The height adjustment range is 12cm and the panel can also be tilted through 30 degrees (five degrees forward, 25 backwards), plus it can be rotated through 90 degrees to a vertical orientation.
All the connections – along with the main on/off switch and the power cord’s plug-in – are on the base and comprise one Display Port, one USB Type B (upstream) and one USB Type A (downstream), two HDMI and a stereo audio output via 3.5mm minijack socket. Two more USB Type A ports are on the monitor’s left side and these are obviously the ones you’d use for temporarily connecting devices, such as a camera or card reader. There’s no built-in SD card reader and no USB-C connector either.
The physical controls are discreetly located at the lower right of the monitor’s rear panel and comprise a joystick controller – which Acer calls the ‘Navi button’ – and four unmarked rectangular buttons. As its name suggests, the Navi button serves as the navigator for the on-screen menus (OSD), with a press action serving as the ‘enter’ command. One of the buttons cycles through the input sources and two are ‘hot keys’ so they can be assigned various functions as desired. It’s all very logical and straightforward so, operationally, the CM2241W couldn’t be easier to set up or more efficient to then subsequently use.
The display comes calibrated for the three main color spaces of RGB, Adobe RGB and DCI-P3, plus there are another four presets designated Standard, Movie, Graphics and CAD/CAM. A 3D LUT (Look-Up Table) is included, enabling hardware calibration independent of a computer’s color management system. You can store two custom calibration profiles and also one user-defined screen setup (for brightness, contrast, black boost, etc.). If you aren’t planning to delve too deeply into the arcane world of digital color management, this is really all you need.
Acer ConceptD CM2 CM2241W: Verdict
As usual, to test the Acer monitor’s performance, we ran software-based calibration using the Datacolor SpyderX Elite colorimeter. The DisplayCal scores for color gamut, tone response, white point uniformity, contrast, luminance uniformity, color uniformity and color accuracy were all excellent. In fact, this display truly excels for color accuracy, which is exactly what you want for image editing, and the really good news is that the factory calibration is pretty spot-on, so you don’t actually need to do your own profiles (which, of course, is an added expense in terms of buying a colorimeter).
Acer has been smart with the CM2241W’s design and specifications because although it’s not a combination of size and resolution that would make headlines any more, the emphasis on color accuracy means it’s very well suited to image-editing applications. Additionally, the ease of setup and adjustment – along with the likelihood of long-term calibration stability – make it ideal for the enthusiast-level photographer who just wants a consistent color accuracy that will translate to great-looking prints. It’s essentially set-and-forget, so you can get on with getting the most out of your photography. Result.
