OVERSCAN, try fix it with H/V sliders but screen is blurry (interpolated)

Hi guys,

i bought new NUC DC3217IYE last week. I have latest BIOS ver.:0042 and latest HD4000 graphic driver.

I have problem with overscan (my TV doesnt have 1:1 mapping, only 16:9 with overscan.).

My old PC with ATI Radeon have in driver menu overscan correction option, after apllying it, screen was sharp and clear!! like 1:1 mapping.

But with NUC it doesnt works! I can see horizontal and vertical sliders, if I correct it with this, size is OK, but screen is blurry, like interpolated, text is fuzzy and hard to read. I tryed every combination of H/V sliders (from 80-100%) without success = still blurry image.

Is thery any option which could help me?

Thanks for any help!
