Dark Shadow on Montior in early evening and morning
-
Since I have been running f.lux I have been experiencing a big dark shadow on the bottom of my monitor when f.lux is not operating. By that I mean during day time when the screen is normal I have this dark shadow for some time in the morning and evening. But not always and when it does occur it goes away after a while.
So, has anyone else experienced anything like this? Is it related to f.lux?
I exited f.lux when it was happening and it persisted.
Also, I contacted HP, the monitor manufacturer and they had no idea why this would happen unless the monitor was going bad. They did not think the monitor was going bad though.
If anyone wants to see what I'm talking about, send me an email and I'll send you an image of my screen. ngarland@swlaw.edu

You can upload the screenshot somewhere and then provide us with the link to it. I think that would be far easier than relying on e-mail.

OK. Here is a link to a screen pic: link text

That link didn't bring me to it, but you meant this: https://normando.smugmug.com/SmugPreview/Flux/i-xjt9tWd/0/O/Shadow Screen.jpg
Is there a bigger version?
Anyway, I've never seen that before and I don't see how this could be caused by something like f.lux. It looks more like it is a monitor problem of some kind. Has HP seen this?
-
Well, HP has not seen it, but after I spoke to them about it they said they thought it might be a failing monitor. The thing is it goes away every morning and has not gotten worse. Also, the monitor is not that old, about a year and a half. I have bought a new monitor and can try it out, but I just haven't had time to deal with it. I got the new monitor on Amazon, so I have till November 2 to return it.

f.lux changes the entire screen at once, so it shouldn't be able to do this.
Looks like a failing backlight?

@herf what is a backlight?
-
The backlight is what makes a monitor work. Without it, the monitor would look like it's off (well, you might see stuff, but it would only be lit up by whatever light is in your room). So when you change your monitor's brightness, you're really just changing the brightness of the backlight. When a monitor goes into sleep mode, the backlight turns off.
Below is a video of a guy repairing an LCD monitor, and toward the end after the 4:04 mark, you get to see him testing the backlight (backlights).

Do you have a TFT monitor? I have a cheap TFT and basically that means the viewing angle is VERY small. F.Lux just exacerbates this problem. If I start directly at the monitor, it gets darker on the bottom and lighter on the top.
Is this like what you're experiencing?

No, he's experiencing this, as posted a little earlier: https://normando.smugmug.com/SmugPreview/Flux/i-xjt9tWd/0/O/Shadow Screen.jpg

Ooh yes this looks like a hardware problem, that's not something f.lux would be able to affect. :(
