"Internet TV", or videos are one reason. Do you want an animated |
| 12 |
postage stamp in one corner of your 1280x1024 display? Software scaling |
| 13 |
imposes a heavy load on the cpu, so hardware scaling is preferable. As |
| 14 |
I mentioned in a previous message, attempting to interpolate partial |
| 15 |
pixels hurts image quality. E.g. going from 1280x1024 to 1024x768 or |
| 16 |
800x600 or 640x480 is bad. |
| 17 |
|
| 18 |
However, you can retain picture quality if you divide the resolution |
| 19 |
cleanly by whole integers. E.g. a 1280x1024 display should be just as |
| 20 |
good at 640x512 or 320x256. Similarly a 1600x1200 LCD would do OK at |
| 21 |
800x600 or 400x300. "xrandr -q" is your friend. |
