I have a GPU fault in my laptop where my machine reacts negatively to deep shades of black(lines and rectangles across the screen, flicker, makes it unusable in some cases). I've been wondering if I could brighten up the monitor my setting the contrast/gamma whiter, like I did in some PS2 games, so I could get rid of this problem.
When compared to other readers, it seems to me that the contrast of some pdf's, especially those produced by latex for instance, is not very good. Some of them are so "bright" they are quite difficult to read. Just in case, is there any setting that allows to have a better contrast for pdf's on the e-reader side that I have missed ?
Scribbles and Snaps: "But what if you have just a single image? In this case, you might want to give the Local Contrast feature a try. It's based on the LDR Tonemapping utility which is designed to improve the dynamic range of the photo by reducing its global contrast and increasing the local contrast."
Spent the money on a screen repair since it felt like the same option. Went alright, but the brightness/contrast has seemed a little off afterwards, and just before the screen randomly got super-bright for no reason for a couple of seconds.
Problem you think? Should I bring it back and *****? Anyone experience similar things?
I have an Acer Aspire one 5742 laptop. I installed Linux Ubuntu 12.10 on it. I have one problem with it. no matter how I press the Fn+ up or Fn + down keys I cannot adjust the Screen Brightness. It is at its maximum brightness and this drains the laptop battery. I did some googling and found out that you needed to change some settings in the grub file but I don't know exactly what to do.
