AOC I2276


Introduction


AOC have hugely expanded their line-up these past few years and have proven themselves very capable of hitting that sweetspot between price and performance. The AOC i2276Vwm uses a 21.5” ADS IPS-type panel, providing the strong viewing angles and colour consistency users have come to enjoy from the technology. There is of course more to a monitor than just the panel. In this review we put the monitor through its paces and find out how appealing the whole package is.


Specifications


This monitor uses a 21.5” IPS-type panel from Chinese manufacturer BOE with a 60Hz refresh rate and Full HD (‘1080p’) resolution. It supports 6-bits per subpixel with an additional 2-bits FRC (Frame Rate Control) dithering to make it up to 8-bits. This is common for such a monitor and not something that should concern most users. The monitor has a 5ms grey to grey response time, but as always this gives little indication of how responsive things will be in practice. The key specifications are given below with some ‘talking points’ highlighted in blue for reading convenience.

Features and aesthetics


The i2276Vwm has a fairly traditional home-office look about it from the front. The bezels feature a brushed metal effect matte plastic and are fairly thick by modern standards (18mm/0.71 inches at the sides and around 20mm/0.79 inches at the top and bottom). The screen surface is matte anti-glare with a fairly ‘strong’ (roughed up) texture. This is more similar to the surfaces seen on older IPS models than LG’s newer AH-IPS panels and affects the image clarity and vibrancy slightly more than modern IPS panels as a result. It doesn’t have quite the same ‘smeary’ look to it but certainly isn’t as ‘clean’ as the surfaces used on the latest LG IPS and Samsung PLS panels.

The controls are located at the central part of the bottom bezel and are as follows; ‘Clear Vision/Right’, ‘Volume/Left’, ‘Power’, ‘Source/Back’, ‘Menu/Enter’. Tactile rather than touch-sensitive buttons are used here and are fairly easy to navigate ‘by feel’. There is no illumination of the control labels nor on-screen labelling which can make using the OSD (On Screen Display) a bit tricky in a dark room if you’re not used to the layout. Another issue with the layout is that the power button is located centrally beneath the ‘O’ of the AOC logo. This is where you would naturally expect to find the ‘right’ arrow and we found we accidentally pressed it a couple of times. The power light is on its own to the right (where the power button would usually be located). A small rectangular white power LED is used which is reasonably bright but not something we found overly distracting.

The OSD itself is laid out in AOC’s typical widescreen format. It is split into sections labelled both textually and with simple graphics. Basic functions include the ability to adjust contrast, brightness and gamma mode as well as set the strength of the overdrive (grey to grey acceleration). You can also customise the colour channels. Other features include ‘Break Reminder’ which displays an on-screen message when you’ve been using the monitor for an hour. There is also an ‘Off Timer’ which allows you to select a time in hours (1-24) after which the monitor will automatically enter standby, reminding you 10 minutes beforehand with an on-screen message. As usual for AOC monitors there is no sharpness control, but we found the default sharpness optimal anyway as we usually do with this manufacturers monitors. There is a ‘Clear Vision’ sharpness enhancement setting, however. The video below gives a run-through of the OSD – there is no audio commentary on this video but rather a quick skim through of the available options.


The monitor is fairly sleek from the side, being 18mm (0.71 inches) at thinnest point with a central bulge beyond this. The stand only allows the monitor to be tilted.

The rear of the monitor has a fairly simple design with a carbon fibre textured matte black plastic covering. There are 100 x 100mm VESA holes for alternative mounting. The ports face downwards towards the bottom; 3.5mm audio output, HDMI (with MHL), D-Sub (VGA) and an AC power input (no external ‘power brick’). The lip where the stand attaches combined with the downward facing ports does make it a bit tricky to connect cables up as there is limited space to work with. There is also a K-Slot to the bottom right of the port area.

Calibration


Correcting the colour signal


An Nvidia GTX 780 was used on our test system connected to the HDMI port of the monitor. As usual the incorrect colour signal was sent out by the GPU; ‘Limited Range RGB (16-235)’. This gives the image an obvious washed out look, adversely affecting gamma, contrast and colours. We used the toggle utility mentioned in this article to correct this, enforcing a ‘Full Range RGB (0-255)’ signal. Some tips for AMD users are also included in that article.

 


Testing the presets


As usual for an AOC monitor, the i2276Vwm lacks traditional presets. There are some useful options available such as a range of ‘Gamma’ and ‘Color Temp.’ settings, however. The table below shows some key readings taken using a Spyder4Elite colorimeter and a range of monitor settings, alongside some general notes on the image using those settings. All settings not mentioned in the table were left at default, with the exception of our ‘Test Settings’ were the modifications mentioned in the subsequent section were made. The table was compiled on our test system running an Nvidia GTX 780 with the correct ‘Full Range RGB (0-255)’ colour signal mentioned above. The results using a modern AMD GPU with colour signal corrected were similar.


Gamma1 (Factory Defaults) 2.2 6427K

- Good balance to the image aside from the uncomfortably high brightness. The warm tint is only very slight and difficult to notice by eye – perception of this depends on lighting conditions.

Gamma2 2.0 6545K

- A slightly cooler tint than ‘Gamma1’, not really noticeable by eye. What was noticeable is the slightly drained look that colours have due to the gamma behaviour.


Gamma3 2.3 6587K

- As ‘Gamma1’ with extra depth to some shades, a little too much in places.


Color Temp. Normal 2.2 7126K Image balance is upset by a fairly strong blue tint.
Color Temp. User 2.2 6758K A slight blue tint again upsets balance, but not to the extent of ‘Color Temp. Normal’.


Test Settings


(modified as below) 2.2 6502K The good balance of ‘Gamma1 (Factory Default)’ is maintained with a more comfortable brightness. Shades have a good rich look and are consistent, showing excellent variety.

The monitor does a good job at producing a well-balanced image straight from= the box, aside from the fairly high brightness. The gamma tracking of the monitor and white point are both very close to their targets which is good. The image below shows the gamma curve of the monitor using the factory default settings.

Unfortunately when you lower the brightness, the colour temperature begins climbing and the green channel begins weakening. An interesting ‘kink’ is then introduced to the gamma curve as soon as you whack the monitor into ‘Color Temp. User’ to modify the colour channels, despite the gamma still averaging 2.2. For our test settings we lowered the brightness significantly and made some modifications to the colour channels. The white point was very close to the 6500K target without any relative weakness in the green channel. The gamma tracking was not quite as tight despite still remaining quite close to the desired 2.2 curve. Visually this made little difference and isn’t something most users should worry about.

The ‘Color Temp.’ setting is set to ‘Warmest’ by default, which doesn’t really make the image particularly ‘Warm’. Setting this to ‘Normal’ makes the image noticeably cool, though, introducing a blue hue that’s fairly noticeable in most light. The ‘sRGB’ setting is pretty much redundant as it is exactly the same as the default ‘Warm’ preset. We would have liked to have seen some sort of ‘Reading’ or ‘Low Blue Light’ setting. AOC could get around this whilst keeping their naming as it as by shifting the default white point settings to ‘Normal’ (which should be roughly 6500K) and making the ‘Warm’ preset actually warm – perhaps closer to 5000K.


Test settings


As mentioned above we lowered the brightness and made some adjustments to the colour channels to reach out test settings. Individual units are likely to differ so don’t assume that these settings will be optimal in all cases. Due to this and the fact the gamma tracking is quite close to the target (with some deviance depending on colour channels) we won’t be providing any ICC profiles for this monitor. Most users won’t be needing to use ICC profiles for this screen and those who do should be creating one themselves on their own system and tailored to their own unit.


Brightness= 37 (according to preferences and lighting)
Contrast= 50
Gamma= Gamma1
R= 48
G= 50
B= 47


Contrast and brightness


Contrast ratios


We used a KM CS-200 luminance meter to accurately measure white luminance, black luminance and calculate the resulting contrast ratio using a range of monitor settings. These readings and calculations are shown in the table below. Blue highlights indicate the highest white luminance, lowest black luminance and maximum contrast ratio recorded. Black highlights indicate that the readings or measurements are for our test settings.
