|thank you both for your answers.|
yes, current monitor is crt.
my Dell pc is about 8 years old with a P3 motherboard.
using windows XP Pro.
my graphics card is a NVIDIA RIVA TNT2 model 64/model 64 pro.
its highest current resolution appears to be 1280 X 1024.
i am using it at 1024 X 768.
new monitors i'm considering are HP, Acer or Viewsonic and offer 1600 X 900 resolution.
this is all new to me. do i have to use the new monitor at that resolution or will it 'work' with a lower resolution setting?
thanks again for your time.
