Okay, I have a laptop and I was wondering if I can connected a 75hz tft but with vga not dvi. Is it possible or is impossible to get over 60hz via vga? I am really confused about this.
It should output whatever the laptop is capable of, most are around 75hz max. The F keys or Func key + something else might need to be used to switch between laptop screen and external.
Only time I done this was connecting it to flat screen tv so I limited myself tp 60hz.
your laptop is limited by what it can output and the TFT will reach triple figures, so you're not going to damage anything.
