Unfortunately, the PLL changed again in moving to Cyclone V. So, you're hitting, essentially, the same problem. Again, you need to re-instantiate the PLLs for the particular device family you're targeting.

Are you using a standard development board for this? Terasic do a altera cyclone ii de1 board (http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=53&no=83) which features a VGA DAC and connector. They offer plenty of design examples - see the 'Resources' tab. I'm sure you can find a suitable VGA example in there. Download the 'CD-ROM'. If you haven't already you'll have to register to allow you to download it.

Cheers,
