hello community, my problem is in displaying bad quality image in VGA using De2-115:

HI, I believed you filed 2 forum thread that link to the same issue. I can see that you are using Intel FPGA University Program IP Cores. Perhaps you check out Video IP suite user doc in below link to ensure you configure the IP correctly https://www.intel.com/content/www/us/en/programmable/support/training/university/materials-ip-cores.html You may also want to consider to look into DE2-115 board user manual doc and also look for close example design in University Program Installer https://www.intel.com/content/www/us/en/programmable/support/training/university/materials-computer-systems.html Thanks.
