Display problems with new PC?

[Joshua97]

This might be a bit long. Just got a new acer computer, it has a nvida geforce graphic card. Set it all up and connected it to my old LCD monitor via the VGA cable, no signal kept on popping up and I can't access the monitor menu unless it has received a signal. I tried connecting it to one of my small HD ready TV's via a HDMI cable, it worked. The problem is that the picture quality was awful, words were fuzzy and I tried everything in the display setting to get it looking better but nothing worked. The second thing I did was connect it up to my other small HD ready TV by the VGA cable, there was no picture on that either, so the VGA seems to not work at all. I then tried HDMI on the same TV and the picture quality was also terrible like the other TV. I cant try DVI because I don't have the cable. I cant connect it up to the old monitor through HDMI because the monitor does not have that port.

After researching both of my HD TV specs I found that they both had 1366x768 resolution, except one of them had 50Hz refresh rate and the other had 60Hz. Tried matching PC display resolution to that and the quality is still bad, no improvements.

Any ideas why the display quality is so bad? Is it because of the TVs? Do I need a new monitor and if so what type of monitor do I need?

Thank you to anyone that responds.

EXTRA INFO: Connected a laptop up to TV by the VGA cable, the quality was fine, so what's the problem?

on newer pc the cpu now has a video chipset in them. make sure your plugging the vga cable into the video card port and not the onboard video port. in the bios look at primany display output make sure it set to peg/pci not auto. so the nvidia card is the first video card output. if that does not help try installing the newest nvidia driver and then in nvidia control panel make sure it seeing your monitor as the right model (some times if it defaults to vga monitor or a non standard unit the display can look bad.). if your using the onboard video it can be the driver from intel or amd or a bios issue with the mb.

Hi thanks for replying. There's only one VGA port on the tower and I'm not sure whether it is onboard or the video card, could you tell me what the difference is?. Also I'm using the TV as the display for the moment as the HDMI cable is the only thing giving me an image. I don't have a DVI so can't try that but I will try what you have said.
