Updated AMD graphics drivers causing screen flicker

I updated my graphics drivers for my Radeon HD 6870 and now there's prevalent flickering on my monitor, even sitting at my desktop idle. I tried my monitor(HP 2509m) with my PS3 and noticed no flickering so I'm pretty certain it was the graphics driver update. My biggest concern is any damage this could have done to the monitor. Could it have harmed it?
 
Anyone? Unfortunately I've been buried in work so I haven't had the time to roll back or get newer drivers. I'm just worried about any potential damage to monitors this could cause.
 
I would uninstall and reinstall first. A lot of problems can be caused by installing on top of the old drivers.
 
I noticed the flickering also this morning, I'll re-install after work and hopefully that fixes it.
 
Argh, the flickering is still there. I can live with it, but can anyone comment one way or the other as to whether this is harming my monitor?
 
This seems obvious, but have you checked the refresh rate setting? Maybe it's changed from the normal 60 - 75 Hz to something stupid like 90 and the monitor is trying to cope with it.

I looked through the Catalyst Control Center and it reports my monitor as having a maximum refresh rate of 70hz, which is false. However, if I right click my desktop, go to screen resolution, the refresh rate there is set to 60hz.

There's also all sorts of things in the Catalyst Control Center that I don't know if they should be checked off or not, such as "Enable GPU scaling, Enable ITC processing". Never heard of such things, but they were off at default so I'm leaving it that way for now.
 
I think I fixed it finally. Uninstalled the drivers, used driver sweeper, then installed the new drivers. Seems to be good so far.
 
I updated my drivers yesterday and noticed youtube videos lagging/not playing. Today my computer was just ruynning terrible and ended up getting a BSOD. The screen read that the display driver failed and called atikmag.sys

I'm going to try re-installing the drivers and see what happens. Using a 6950.
 
Any updates Smartazz? I've noticed that I get this too with post 12.2 drivers including betas. Interestingly, I also have a HP2509m as my display. Could be related. I also think it has something to do with graphics card overclocking and the newer drivers. I noticed you have yours pretty overclocked. Since unofficial (past CCC limits) overclocking was recently dropped, I have to inject a couple older dll files into windows (or MSI Afterburner) to overclock properly and especially with Crossfired 5850s. Could be related to this for me... all I notice is that the flicker or display tearing, only seems to happen if I overclock past CCC limits. I also only see the flicker in a 2D environment and not in 3D games. Weird.

Another side question, do you have problems with HDMI and scaling on your 2509m with an AMD graphics card? I'm using DVI now, but for some reason I found the picture a lot more pleasing with HDMI and want to switch back. Currently when I try HDMI, it forgerts the 0 overscan setting every boot and zooms my desktop in to far. :S

Two post up, he said he fixed his issue by uninstalling and reinstalling.

I should have mentioned that I always use driver sweeper and uninstall/install the latest drivers (including betas). This has existed since 12.2 for me.

I just wanted to see where he didn't follow up, that assuming it was gone completely or if it had resurfaced. It pretty much happens when I overclock past CCC limits, despite being able to easily do that with past drivers.
