Windows 7: Dual Monitor Issues

Dual Monitor Issues

Hi all,
i always had a dual monitor system. My Previous setup was a 1920x1080 main monitor, and a smaller 1300x... monitor as my 2nd monitor. I had no issues at that time.
Now i bought myself a new Monitor, a BenQ RL2455HM in 24". And here my problems suddenly starts....

1. if i scroll up and down on websites (using Firefox) it feels wrong, it's not very smooth and sometimes i get a "flickering" issue while scrolling.

2. my desktop doesn't work like it should. It seems like windows doesn't know when the taskbar ends, so that the name of the icons are unter the taskbar, and therefor not readable anymore.
Also on the last row of desktop icons (the bottom one) aren't working like they should. I can only use the First 4 and the last icon slots. The other slots aren't useable (can't place any icons there.

I really really hope that u guys can help me out.
Here are my computer specs:

GPU: 4096MB Sapphire Radeon R9 290 Tri-X
Windows 7 64bit
RAM: 16GB Corsair Vengeance Blue DDR3-1600 DIMM CL10 Dual Kit
CPU: Intel Core i7 4770K 4x 3.50GHz So.1150 BOX
Old 2nd Monitor: LG W2443T
New 1st Monitor: BenQ RL2455HM

I tested with 2 cable layouts,
First Try: Both with DVI cable.
Second (and current) Try: 2nd Monitor with DVI and the new 1st Monitor with a HDMI connection.

I also already completely uninstalled my AMD Drivers - and installed the newest stable version 14.12 Omega with CCC.

Both Monitors run with native resolution 1920x1080

Is the problem now on both monitors, or just the new one ?

Test with just the new monitor, still problems ?

Return it.

A second monitor and your resolution setup to extend these displays should not give you any problems, and there was no need to change any drivers.

Run windows update, there is sometimes a monitor driver, it may help.

hi thanks for the reply
the problem (atleast the scrolling one) is on both.
However when i go to single monitor i have no issues at all (with none of them)
also when i am ingame (lol or elder scrolls online) my browser and other application start to lagg, which should not happen with my gpu and pc specs.

my windows is always up-to-date

edit: tried to disable aero but didn't changed anything
