I bought a high definition asus LCD monitor two years back. But its high definition video is not working properly. The picture quality is getting dull. I called my brother-in-law who is a technician, he told me that I should change my ASUS EAH4670/DI/512M/A Radeon HD 4670 512MB 128-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card which is a high definition video card. I did not know anything about high definition video card. Is there anyone who knows about high definition video card of asus vh242h? Please tell me how to change it.
