The AOC i2757Fm is a PC monitor with a 27-inch IPS screen and two HDMI ports that sells for as low as £220. But in this case, low price does not mean a thick frame and an ugly design. Is the i2757Fm the perfect merger between low cost and quality?

Design & Build3/5

AOC i2757fm - front

The body looks great. Until you touch it you would swear it's made out of metal, but it's actually grey plastic.

AOC i2757fm - border

With the monitor turned off the screen practically disappears into the 5-mm-wide borders lining the top and sides. Also interesting, it's only 2 cm thick along the edges, making the monitor thinner than usual for this price range.

The display only tilts by a few degrees. The stand doesn't pivot, the height is non-adjustable and it does not rotate into portrait mode.

AOC i2757fm - back

All of the connectivity is on the back. It includes two HDMI ports (one of which is MHL-compatible for transferring HDMI signals from compatible Android smartphones and tablets) and a VGA port for analogue video.

Also on the back is a pair of bass- and volume-deprived speakers whose biggest advantage is that they don't saturate. If you're itching for better sound, you can always use the HDMI port to connect the monitor to an external sound system or plug headphones into the audio in. Remember, VGA only transmits video signals, so if you're connected via VGA you'll also need to connect your PC via the audio line in before you can hear any sound.

Those are all the functions you get on this monitor. That's fine for standard usage, but not enough for us to give it more than three stars in this section.

Colours & Contrast4/5

AOC did some great work on the colours. Despite huge variations in the greyscale brightness (dark greys are too dark and light greys are too light), we measured the Delta E to be an excellent 3.1, without changing any of the settings.

AOC i2757fm - deltaE

We usually warn against monitors with Delta E's over 3, but here only hardcore aficionados and ultra-demanding photographers or graphic designers will notice the difference.

The contrast is also outstanding, at 1,150:1.

AOC i2757fm - orange

The colours on this IPS display stay constant when looked at from an angle. TN panels, by contrast, become darker at the top of the screen and lighter at the bottom when viewed from an angle.

Unfortunately, the model we were sent to review sometimes leaked light out of the lower left-hand corner. It wasn't much, but astute users will notice it in an all dark room.


As usual with IPS monitors, the i2757Fm is not ideal for gaming. With a ghosting time of 13.5 ms, fast motion appears blurred, so much so that video games that require quick responses from the player, such as first-person shooters, aren't really worth the trouble.


AOC i2757fm - responsiveness


This graph shows the ghosting time, measured in ms, which measures the time it takes this monitor to entirely remove the previous frame. The shorter the time, the more fluid moving images will appear.

There's one feature that's supposed to improve the response time, but it basically just causes reverse ghosting. The best advice we can give is to stick with the default settings.

It's a shame about the ghosting, because the average input lag is just 9 ms. Input lag measures the delay that occurs between the moment the signal is sent to the monitor and the moment the image is displayed onscreen. Here, 9 milliseconds is well below the lag that the human brain is capable of perceiving, so if it weren't for the ghosting issues, this would have been a great monitor for multiplayer video games.

4/5 AOC i2757Fm DigitalVersus 2013-08-12 10:07:00


  • By default, Delta E is 3.1 (accurate colours)
  • Contrast: 1,140:1
  • Wide viewing angles (IPS panel)


  • Not responsive enough for gaming
  • Resolution "only" 1920 x 1080, instead of 2560 x 1440


The AOC i2757Fm has superb colours and high contrast, but it would need a more adjustable body and higher resolution to join the Asus PA279Q in the category of five-star monitors. That said, at this price it has great value for money and would be a perfect choice for anyone who's picky about colours and low on dough.
