    Hi There

    I have been running Parrallels 13 on my machine for a few days, but now have upgraded to High Sierra and now each and every time I launch my Windows VM the resolution is off. The screen looks like the below

    So I get those horrible black bars on either side and I have to adjust the resolution to a different size, and then back to my normal size in order for it to no longer looked squished.

    For my Parallels settings, I have the Graphics set to Scaled Resolution and this problem is occuring on my Laptop screen, not my external screen (I have an Apple Cinema Thunderbolt Display plugged in and everything set to full screen and use all screens in full screen mode).

    This is a very annoying process I have to go through each time I start up my VM (daily) so could really do with a fix please.

    Cheers
    Paul

    I get a screen resolution problem too, only one screen resolution : 1024x768, on an iMac 5K 27" + High Sierra.
    Best Regards

    Hi @Navitas , please try Actions > Reinstall Parallels Tools and let us know if that works.

    I have the same issue. Resolution is 1024X758, and it's the only option. I've reinstalled Parallels tools 3 times, no change. I altered the config, and allowed for 1Gig of gfx memory, no change. Also noted that there is a yellow triangle with ! in the High Sierra title bar. It doesn't go away, and shows the "Install Parallels Tools" option.
