AOC m2752Pqu LCD monitor full review
If you like to have a lot of screen to look at then a 27” display is a very attractive option. The trouble is, a 27” IPS panel is likely to be fairly expensive whereas 27” of cheaper TN technology may just make all the shortcomings of the technology that much more obvious. Into this breach then steps the AOC m2752Pqu, an LED-backlit LCD panel that is part of the AOC Professional MVA range. The Multi-domain Vertical Alignment panel uses 24-bit colour like IPS panels but is cheaper. The actual panel itself comes with a telescopic stand that rotates the display into a portrait orientation and has 110mm of height adjustment. It also rotates around on the base so aligning it for comfortable viewing or showing someone else an image on it won’t be a problem.
While not exactly square and chunky, there’s a sizeable bezel and thickness to the edge of the display, and like AOC’s other MVA panel we reviewed recently, it has a brace of USB ports stuck to the side in extra housing. Thankfully this isn’t a square block like the last one, and indeed, gentle curves are the order of the day all over the casing. Around the back there’s a plethora of interfaces, all fitted face on so they are easy to access quickly. There are DVI-D, a brace of HDMI, D-Sub analogue, four USB and DisplayPort interfaces plus built-in speakers a headphone and audio line-in sockets. The monitor menu controls are built under the front-right side of the panel, but the labels are simply made from the same plastic, making them impossible to read when the monitor is on. By trial and error then, the first button cycles through presets for typical uses for the monitor, from regular computer work to action, gaming, films, text and web viewing. Then there’s volume control and input selection. The fourth button along finally brings up the on-screen menu, but navigating it is entirely hit and miss as it then uses the other buttons, but you don’t know which ones. However, this reveals the Eco presets, which were the shortcuts on the first button, and simply alter the brightness. Typical power consumption is 44W when on, 0.4W on standby and 0.3W when off.
The big-screen display has a solid surrounding bezel and a brace of USB ports on the side for easy access.
So let’s look at some numbers now, starting with the resolution which is 1920x1080. On a 27” monitor, this looks fine for most uses, but text doesn’t look that crisp. You may hanker for those models that offer 1920x1200 or a higher resolution altogether. The contrast ratio is 1000:1 with a dynamic ratio of 20,000:1. This is fairly standard and in most uses the contrast is fairly flat but the dynamic option is very effective and delivers quite a lot of contrast when needed though this will be at the expense of highlight detail. On the brightness side this is rated at 300cdm2 which is fairly high, making this ideal for bright offices or work spaces. In the brightness test itself the results were excellent with clear graduation all the way through the highlights and right down to around 97-98% of the shadows. This is far better than TN panels and what you might expect from an IPS panel.
On paper, the 8ms refresh rate doesn’t sound too good and in practice this showed up with ghosting on a variety of image tests. These are based on using contrasting colours, often against grey backgrounds, which in real terms don’t occur that often. So, on the actual practical tests, fast-moving racing and first person games plus films showed no evidence of image trails and ghosting, the moving images simply look slightly softer. You aren’t really going to notice in practice. There’s no obvious effect from moving standard Finder or application windows around.
There are plenty of options on the interface front from HDMI, analogue D-Sub and USB to DVI-D and DisplayPort.
To the solid colour tests and where MVA panels can have some troubles. While the viewing angles are excellent, you can look around from lots of angles, there can be an issue where the colour appears to change depending on the angle you are looking from. Given this is a whopping 27” screen, there could have been real issues here. Sitting in the middle of the screen it is actually very consistent, and moving around to check each area the colour is the same throughout. What is apparent though is if you move off-centre in line with one edge then the colour of the opposite third of the screen gets diluted to a weaker version. The worst affected is red as this starts to look more orange. Overall though, this isn’t that bad and the actual colour is really consistent. Checking for light leaks shows none so the build quality is fine and on white-screens there is no darkening in the corners. There’s some yellowing at the edges but it’s only slight.
