I am not sure if it does matter but i found some charachterstics:
Horizontal frequency: 30-96kHz
Vertical frequency: 50-160Hz
Recently i switched on on 100Hz reflesh rate on 1024/768. It is working quite well. I also switched it on on 160Hz and it was again working without problems.
That seems to be on of my biggest problesh. Which reflesh rate should i choose not to destroy/damage my monitor?
