To test today, we are using a LaCie calibration gun along with specific software to accurately measure the readings. We also test the monitor in real world conditions, with an AMD HD7950 and Quadro 4000M discrete graphics.
We measured the Gamut out of the box and the Asus VN247H returned a reading of 2.18 which is very good. We manually adjusted the gamma to 1.8 and the panel returned a 1.79 result.
Colour response is good at the default settings, and depending on the ‘Splendid' mode selected the colours can be under, or over saturated. We feel it is important to spend a little time calibrating the VN247H to get the most from it.
It is clear that this panel is not designed for professional, mission critical colour work however the overall impression of the image quality is positive, with a great depth to the colours, especially when gaming.
Text focus is sharp and backlighting is reasonably consistent across the full width of the panel. The out of the box sharpness settings seem a little high, we reduced it to '40' and the edges of small text were less aliased. There is some bleeding at the edges and corners of the screen, although this is to be expected at such a low price point.
Panel Linearity is average, but perfectly fine for the intended use, which is gaming.
Black Definition is very good considering the budget price point with a relatively clean image presented, even when watching high definition films. Both SunShine and Moon delivered a punchy image with good focusing and rich colour saturation. The VN247H won't match leading panels in the £250 price bracket, but I found the overall image to be pleasant and convincing.
We measured a variable between +10% to +18% in the middle section of the panel, with the corners running between 20% +23%. To the naked eye there was a slightly noticeable shift bottom right.
White purity wasn't quite as impressive, although again this is rarely noticeable when gaming. Critical analysis when playing high definition bluray content (HDMI 1 connection) via the OPPO BDP95 did highlight an image which could seem slightly ‘dirty'. This was obviously more pronounced when viewing media shot outdoors in bright conditions. Again, it didn't look too bad to the naked eye, but immediately noticeable if you are moving from a panel with superior characteristics in a higher price bracket.
Panel Uniformity rated as good, with some distortion, close to the sides and more pronounced on the right. Colour accuracy rates above average for this price sector. Some of the preset options can greatly change the output intensity of colour, so it is worth spending some time adjusting them to suit. Gradients were reproduced well, with only a little banding evident.
Viewing angles were average, with some colour shift on both vertical and horizontal planes.
The screen returned a fantastic result in our real world gaming tests. I noticed absolutely no motion blur or artifacting with a variety of fast moving first person shooters and racing games.
The VN247H is an extremely efficient 24 inch screen, demanding around 30 watts when it is calibrated. Out of the box, it was taking around 34 watts at the socket.
