I tried everything from changing output profile to Tablet in page setup to disable compression and do not convert all images to jpeg in MOBI output. Can someone please help.
Thanks in Advance
I think it's due to incorrect settings in calibre.

To fix this, go to Preferences > Common options > Page setup. Change Output profile to Tablet and Input profile to Default profile.

If you have these options set wrong, hi-res images will be reduced in resolution. A setting of Tablet does not change images at all.
