My archaic CRT monitor has a resolution of 1024x768. My GPU is an Intel 82945g chipset, CPU is P4, 1GB RAM running Windows XP. I want to replace the CRT with a TFT which comes with 1366x768 resolution.
My question is: Would it be computationally expensive on my CPU in any way to display on this new monitor with higher resolution relative to the older one? (The older one used to work just fine when it was working)
My doubt arises from the fact that, when I try to play high res movies on the old monitor, they lag maybe, because of the transformation (scaling) performed by the media player but this is a purely CPU issue as far as it seems. Replacing with the new monitor would mean, the CPU sending an array of now 1366x768 color pixel intensities.
I am confused about this. Is it over the display video card to handle it independently by means of parrelism or something or actually means CPU churning more cycles to keep up?
Can I safely replace it with a 21 inches Monitor (1920x1080) HD monitor?
