Weak contrast in Elitebook 840 G3 15"

[caribu]

The contrast of this display is not the same quality like the previous Elitebook models.

Specifically, whichever brightness I set, with a black screen (e.g. black background in Windows 7 or during startup with the bios information only) the screen is never black, but actually grey.

It seems like the background light source is always leaking a bit through the display. I can tilt the display so that the upper edge is totally black or the lower edge is totally black, but I cannot tilt it so that all the display is black. There is always some backlight leackage.

The consequences of this fault is that the leakage affects the crispness of the text. The text always occurs a bit milky and not sharp. This has negative impacts on my sight with some hours of work. It was not like this with your previous HP elitebook models. They had perfect contrast.

Our government agency (MeteoSwiss) has bought many of those new replacement laptops but all of them have this issue. Is there any fix to that or is there any recognition at HP that the display is of much worse quality.

Any thing to be possible to adjust on the user side? Is there any possibility to replace the model wtih a better display? Is there a certain series which was faulty? Is there any insight from HP on this issue? Is there any confirmation from HP to this issue at all?

Sincerely,

Caribu (Reto Stockli)

Hello caribu,

Can't confirm leaking because I can't actually see it but what I recommend is performing Windows' Display Calibration:

1. In Windows' Search, type Calibrate display color
2. Go through the steps to adjust gamma and the blue/red/green sliders

In terms of the text crispness issues, try this:

1. Search Adjust ClearType text
2. Go through the steps and select the type of text design/crispness that you wish to see on your monitor

Hope this helps,

Eddy
