Hi all hope someone can help me. I haver recently upgraded my PC base unit to a HP with an NVIDIA GeForce9300GE graphics card. I have connected the PC to the TV via HDMI and set the resolution to 1024 x 768. If I try to change the screen resolution the screen goes black and more blurred.The PC runs great and the desktop looks fine but when I am on the internet the image is not sharp and is slightly blurred. Would it improve if i changed the HDMI cable to a DVI cable? I really do not want to invest in a new monitor as I would need to buy speakers and a TV card any advise would be welcome.
