Just so you're up to speed, the first version of the AOC e2795Vh monitor came with a panel that used MVA technology.  It sailed through our demanding tests with flying colours and came out with our top score of five stars.  But since then, AOC has had problems finding enough MVA displays.  The firm decided to replace them with more readily-available TN panels, but without changing the model number—or telling anybody.

One of our readers pointed out that his e2795Vh had a TN panel, so we contacted AOC France, who quickly acknowledged the problem and told us that deliveries of MVA-based monitors has been cancelled until further notice.  That means that once the current stock of MVA displays is sold out, only TN-based monitors will be on sale.  It seems that AOC's European office found out about the switch, which was decided by the company's head office in Asia, at the same time we did.  To prove that they had nothing to hide, they promised we could test the new version with a TN display.  That way, anybody who still wants to buy the 'new' e2795Vh, will know what they're getting for their money.

So much for the introduction: let's get on with the test.  The AOC e2795Vh's basic specs are as follows: it's a 27'', 1920 x 1080 pixel monitor with a TN display which has a 2 ms response time.

Hardware: it's all there apart from the stand—and the viewing angles

There's been no change in this department, and both versions of the e2795Vh have the usual VGA, DVI and HDMI inputs, as well as a headphone jack in the case the speakers aren't up to your expectations.  There's a four-port UBS hub, with two on the side and two at the back.  The one thing that's really missing is a stand with enough flexibility to make adjustments other than simply tilting the screen back a few degrees.


There's a big difference in how even the colour reproduction is on the new TN version of the e2785Vh compared to the older MVA version


One obvious implication of switching from MVA to TN technology is that the viewing angles on the new e2795Vh are much tighter, especially from one side to the other.  As you can see from the image of the orange circle above, colours are no longer anywhere near as even across the whole surface of the screen.

Colours: less accurate

With its default settings, the e2795Vh has a colour temperature that's too cool, leading to grey shades looking pink.  Switching to the warm colour temperature improves things a little, but the results are still a long way from being accurate enough to please more demanding users: the deltaE is 4.3.

The only way to get accurate colours out of this monitor is to resort to a calibration profile.  If you're interested in going down that route, remember that all of our profiles are designed to be applied with the default settings still active.

The e2795Vh produces contrast that's above our average figure of 850:1.  According to our results, it reaches a contrast ratio of 1100:1, meaning that the TN version does as well on this front as its MVA predecessor. 

Responsiveness: an improvement!

This is one area where the TN version of the e2795Vh can make up some of ground lost to the MVA version.  TN panels with a 2 ms response time—good ones, in any case—are the most responsive there is and are therefore well-suited to gaming.

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

It actually does slightly better than the original version, which has an average ghosting time of 10 ms, falling instead to 8.5 ms.  That sees its rating upgraded from four to five stars in this area.  However, the two monitors have one thing in common: a slight hint of reverse ghosting.  Once again, we looked for it everywhere, and it wasn't visible in games, films or office applications.  It seems that it only crops up in extremely rare cases and demanding situations like our tests.  Gamers, then, can happily plump for this monitor.

The input lag is also more or less the same.  The time that elapses between the monitor receiving a signal from the graphics card and when it is actually shown onscreen is so negligible as to be invisible to the naked eye.  It won't, therefore, cause any problems for multiplayer gaming sessions.

Not only does this monitor suffer from the traditional weakness of struggling with SD sources, the TN version of the e2795Vh has inherited a problem from the MVA model in the shape of a picture strongly affected by the snowstorm effect.

The problem remained, even after turning the brightness right down and switching to film mode.

PROS

  • Responsive
  • Good value for money
  • Good contrast: 1100:1

CONS

  • Very light traces of reverse ghosting
  • TN panel, so poor vertical viewing angles
  • Colour reproduction could be improved: deltaE: 4.3

CONCLUSION 4/5

We definitely don't condone AOC's decision to change the hardware in its monitor without telling anybody, but we have to admit that the e2795Vh has some strengths. Most importantly, gamers are likely to be wooed by an excellent response time. And everybody else will like the great value for money.
