Question Sharpness not available in OSD on HP L2208w

[ArrayON_56]

Hi, I have an old HP L2208w monitor and I just can't access sharpness in OSD. Is there anything to do for unlocking it, or it's just not available for this model? I searched google about it, but didn't find anything.
thanks

edit: sharpness setting is in OSD, but it's greyed out. Also this monitor doesn't have any other inputs than vga.

There is nothing to unlock --- the OSD options & settings are what they are. I have a brand new mid-range Acer monitor and that doesn't have sharpness adjustment either -- nor did I expect it to have. Usually only a feature on televisions, I've never had a monitor with sharpness adjustment though it's possible that top-of-the-range monitors do.

ok, I forgot to mention that it's there in OSD, but greyed out, I'll add it to main post.
