So you bought a linux computer, a linux server etc. and now you want to configure the vnc and I guess you're okay to pay ~16(?)USD per month a year upfront, which is what Real VNC offer for enterprise plan to its users - for minimal direct connect plan, which is 200$ a year.
//All steps same important! If you skip one you'll just experience a different lag issue 1. Home LAN Network with good Wifi/Ethernet preferably 800Mbs at least. I use Archer D5 1200 TP-Link Modem. 2. Direct connection via VNC. *NOT a cloud one* 3. Change your screen resolution to MAX 1200 width. #800MBs wifi not less important 4. Connect your vnc server via Ethernet to your router. That's it. It will solver your problems. Enjoy!
& That's it. It will solver your problems.
Real VNC is the standard VNC installed in your company, I don't owe nor own any rights for them. I'm not their employee, nor I'm advertising their product. This is the program/piece of software of my choice and I literally choose them by their trademark: (you for sure know that icon from your desktop toolbar button) image.
