Philips Gioco review: Ambiglow on your desk and much more

Philips 278G4DHSD makes great use of the LG Display IPS panel


Test results brightness and contrast

We compared the Philips Gioco 278G4DHSD with 18 other 27-inch monitors in the same price segment. The new Philips monitor is represented by the blue bar in the charts.

Brightness max.

The maximum brightness is important for being able to view a display in bright environments. The rule of thumb is that 200 candelas per square meter is enough. For office environments it's usually 250 cd/m² .

The Philips Gioco 278G4DHSD has a brightness of more than 280 cd/m². It's more than enough, even if there are even brighter screens. Whether even brighter is better, is another question.

Brightness min.

The minimum brightness is a good indication for how rich in contrast a display is. A lower minimum brightness has more influence on the contrast ratio than an increase in maximum brightness. Since TFT panels always have a light source, achieving absolute zero is almost impossible. Only VA screens are able to get close to that point.

LG monitors, including the IPS237L-BN, have an exceptionally low minimum brightness, and that's because the backlight is turned off completely when the screen is dark enough. You could call it cheating.

Philips doesn't employ this trick but still has a very good minimum brightness of 0.23 cd/m². Very good, especially for an IPS display.

Brightness uniformity

Brightness uniformity indicates how evenly a display is illuminated. Values above 75 percent are acceptable, more than 80 percent is "good" and more than 85 percent is "very good".

The score of 79 percent isn't bad, but we expected a little more here.

Contrast (checkerboard)

In the most important (and most challenging and realistic) checker board test the true performance in terms of contrast is indicated. The Philips Gioco 278G4DHSD does well for an IPS display. Its 381:1 is better than that of many IPS displays, including the LG IPS277L, the oen that cheats with the backlight.
