Here is the Korean Crossover Manufacturer website: http://crosslcd.co.kr/
But you need to translate the page into English. I could locate your Crossover Model to see if they had a Monitor Driver to download and install.
By any chance have your tried Windows 10/11 Settings -Display to see at which Resolutions your Crossover Monitor might work correctly?
Also play with Windows Settings Monitor Frequencies to see if it will display properly at a lower Frequency.
