Hi! I just bought a cpu and I'm using a tv not a monitor so I bought a vga cable because they didn't have any hdmi ones. My problem is,
My default resolution is 800 x 600 even though the tv is 19 "inch-ish" I guess, so whenever I try to increase my resolution it says "No Signal".
But it's okay, that's fine.
But but! That is, without my video card.
So when I do put in the video card I mean update or something like that.
It says no signal but this didn't happen until I maxed out the resolution with video card on. So whenever I use my video card it says no signal forever.
