Dell Inspiron 1720 Laptop 17" 2.4Ghz 2GB 160GB W10
The silver keyboard does not only look good, it is also user-friendly. The keys were not too densely located, tough even an additional numerical pad is provided. This is an essential pro compared to the 9400 series. .
The size of the keys is alright and typing feels very comfortable. The keyboard is located out of the center, a little bit more to the left, in order to provide space for the numerical pad. So, you'll maybe need to adapt to its location first. The same applies to the touch pad.
Anyway, the touch pad is our next point of critique too. The touch pad did often not react well. Sometimes, the mouse pointer resisted to move where intended. However, we could not trace back, whether this is a hardware problem, a software problem, or even a Windows Vista problem.
The pad's surface convinces by good sliding properties, and also its buttons have a clear point of pressure.
A number of hotkeys, i.e., buttons for volume control and control of the Mediaplayer, are beautifully located at the rounded front edge and are illuminated by blue LEDs, if used.
The reviewed Dell Inspiron 1720 was equipped with a 17 inch 1440x900 WXGA+ "TrueLife" display. Overall, we cannot really recommend this display. Considering it is a 17 inch display, even the resolution seems to be rather coarse and not really concise.
Fortunately, the Inspiron 1720 is also available with an WUXGA "Ultrasharp" display with a resolution of 1920x1200 (reflecting alike the WXGA+ panel), which is clearly conciser. Maybe it's the same display the Dell Inspiron 9400 is equipped with, which rated passable in our review.
The measured maximum brightness of the provided WXGA+ display amounted to 194.1 cd/m² in the center of the display. Because the brightness diminishes a lot next to the bottom edges (only 124.2 cd/m²) the poor illumination is only 64.0%.
The average brightness of the WXGA+ displays of only 155.6 cd/m² reveals the maximum as outlier. The minimum brightness of 0.7 cd/m² combined with the maximum brightness gives a maximum contrast of acceptable 277:1.
Because of the heavily reflecting surface of the display which heavily reflects especially in bright environments, the outdoor usage of the Dell Inspiron 1720 is very limited.
