Okay I just put in a new video card tonight. It is a Sapphire Radeon HD 7770. I am having some issues with overall picture clarity. Things are generally fuzzy, it's really hard to read text, pictures are VERY hard to see, they look pixelated and blurred together, there's a black border surrounding my normal display, and it's clear that this is not how the display should look like. Additionally, the color is slightly off, it looks like it has somewhat of a blue-ish tint. The resolution is set to 1920x1080 and 60 Hz. It would seem on the surface to be a driver issue, but I installed them via CD, and then I updated them through AMD's catalyst control center, but it hasn't improved things. I am replacing an old video card, an HD Radeon 4550. I uninstalled the old card and its drivers before installing the new ones.

My specs meet the requirements as far as what's on the box and online:

Processor: Intel i3-550
450W Power supply
1 TB Hard-drive
Running Windows 7 64 bit

It's an Acer desktop I bought about a year ago, refurbished, off Amazon. I've never had a single problem with it until now. I had replaced the Power Supply last year when I put in the 4550. I have the card hooked up to the power supply and it is firmly placed in the PCI-e slot.

Does anyone know where to go from here? :\
