This is a tricky one to describe. I have recently upgraded my desktop PC and am having difficulty with the display, particularly for photographs. The monitor I am using is a BenQ XL2411Z which looks really good when playing games, internet browsing and office applications. When viewing photographs a majority of them have really terrible colours. The same photographs are displaying fine on other devices. I thought it could possibly be the graphics adaptor so I connected a different monitor and the photos displayed perfectly. So I connected the BenQ monitor up to a notebook and viewed the same photos and again they displayed perfectly. This is really puzzling. On the one hand the monitor looks fine on other devices and other monitors look fine on my PC.
The graphics adaptor in question is an ASUS Radeon R9-290X DirectCUII-OC. This is connected to the BenQ monitor via DVI. I am running the graphics adaptor with default settings and the latest drivers and BIOS. The BenQ monitor is also running in default settings, although there are different profiles I can set it to, but the photos display terribly on all. I have tried adjusting the colours on both the monitor and within Catalyst Control Center, but this doesn't make a difference to how badly the photos look.
It is difficult to describe exactly how they look. Where the photos are quite bright seems to look fine, but where there is a darkness such as shadows on a persons face the colours just tend to fall away, don't blend well so they look like early 90's 256 colour VGA. This is the best way I can describe it.
Now here is the interesting part. I borrowed an HP LE2202X monitor from work and connected up next to my new BenQ via DVI to the second DVI output of the graphics adaptor. Windows detected the manufacturer and model of the second screen straight away as it did with the BenQ. I ran them in extended desktop. I opened up a photo on the BenQ side and it looked terrible, then I dragged it to the HP side and it looked perfect.
The next thing I did was to clone the desktop with the BenQ as the primary monitor and opened up the same photo so it was displaying on both screens at the same time. The photo looked terrible on both screens. It was like the HP adopted the same settings as the BenQ.
Then I kept the monitors in clone mode, but set the HP as the primary monitor. The photo looked brilliant on both screens!!! How can this be? Once I take the HP away everything reverts back to the way it was with the photo looking terrible on the BenQ.
I'm really at a loss as to why this is. Does anyone know why this is behaving in such a way and do they know what I can do to fix it? Appreciate any help and advice.
