The AS4315UT model from Iiyama is another representative of the “middle class”. The manufacturer promises 150 degrees horizontal and 125 degrees vertical viewing angles, 250nit brightness, 350:1 contrast ratio and 25ms response time. Besides the standard D-Sub, this display has a DVI-input, which in fact is no rarity for a 17” model.
The overall elegant exterior is somewhat spoiled by the bulky vertical pole of the base that allows adjusting the height and tiling of the display. The menu is rather unhandy, especially its three-page structure. Still, you won’t have to use it often – brightness, contrast and self-adjustment are accessed by means of “hot” buttons.
Side viewing angles proved good, while the view from above or below was worse: the screen grew dark. Screen brightness is of average level. During work, I set brightness to 40% and contrast to 43%. When brightness was at maximum, gray vertical lines become visible at the black background. If you try to remove them by manual fine-tuning, text reproduction quality worsens. On the other hand, maximum brightness and contrast settings should only be used in games – it’s inappropriate to use them at work.
The display didn’t make it to its specs and showed 22ms pixel rise time and 7ms pixel fall time.
