Resolved Question

Why does my display brighten in steps?

Mar 16, 2012 8:55AM PDT

Beginning about a week ago, when I open an application that has a bright background (Word, MSN, etc.) the display brightens in about ten steps, lasting a second or more. This is new behavior.

At about the same time, when I open a web page that has several "sub-pages," the page opens, and if I move the mouse, another sub loads. This repeats three or four time until there is no new information to be displayed. (MSN or Optonline)

I recently reloaded IE9. Any connection?

HP Pavilion, Win 7 Pro, NVIDIA Gforce video card, HP monitor, 6 GB RAM.

Any ideas about how to fix this?

Thanks,

Vince

This was fixed by turning off DYNAMIC CONTRAST via the display menu. This also fixed the stutter-step opening of web pages.

Go figure!

Looks like you got no bites on that one. I've an HP monitor but mine doesn't seem to have that feature but it's not a newer model and a 5:4 aspect ratio. I'm suspecting this is some sort of adjustment based on ambient lighting such as some LCD TVs have.

Steven,

Thanks for the input.

I had been trying to "fix" the problem via Win7 but was having no luck. Finally, I tried the monitor itself and when I got to the part about Dynamic Contrast I remembered seeing a reference to it concerning some other strange display behavior. Luckily, it worked.

I still am surprised, though, that it also influenced how it seriously slowed down the opening of web pages.

Regards,

Vince

Oops! The slow opening of certain web pages is still with me.

What happens is this: I go to a web page and begin to scrooll down. Another bit of the page ( usually an additional graphic) appears, at which tme the screen jumps back to the top. This can happen three or four times.

I have tried opening a web page and waiting for five seconds or so, and that seems to help.

Trouble is, five seconds these days seems llike an eternity!

Not a clue here but sounds like some web page refresh
Apr 2, 2012 9:04AM PDT

setting or software. I know there are some web pages that refresh themselves at some timed interval such as those dealing with live sports scores. I do wonder if your monitor came with some software rather than just a driver that could interact with the screen in real time. You'd know if you installed such a thing. Best I can wish is good luck.

Display jumps to top of web page as new graphics are added

I guess I'm "sure" that it's a software setting somewhere, somehow. The computer and monitor are almost two years old and this phenomenon started only weeks ago. I must have set something wrong (again!).
