Hi,
I just got U3417 S/N: CN-0660X8-74261-71O-0E2L and have problems with config of PBP.

When enabling in 3440x1440 resolution in any of two PBP modes, picture is squeezed or extended with black stripes(above and below) - this is expected. When resolution changed to 1720x1440 in single mode, it is correctly displayed on the middle, with black stripes at the both sides. But when enabling PBP in this resolution, it is wrong either way. One mode it is further squeezed horizontaly, so the picture with two black strips on sides is put on half of the screen. In other mode the aspect ratio is ok, but picture is not full-half-screen, but only in the middle of half-screen with black border around it. As the "aspect ratio" is disabled in menu in PBP mode i cannot play with it.

I tried restoring factory settings, resetting it and restaring PC. PC has latest drivers and sees all the resoultions as valid.

Can you share some hints?

Thanks!
