Hi,
Yes you can remote connect to your PC in Slovakia from USA, but you will need to configure VPN or Remote Desktop gateway.
If no VPN and RD gateway, you could use below third party tool -- TeamViewer
There might be lag and sudden disconnection issue. If you encounter this issue, you can try below settings to see if it improves some.
- When connecting, configure "Low-speed.." in Experience tab.
- On remote desktop (Slovakia), configure below local group policy.
Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Session Host > Remote Session Environment
a. Limit maximum color depth -- select low bit
b. Configure image quality for RemoteFX Adaptive Graphics -- select low
c. Configure RemoteFX Adaptive Graphics -- select Optimize for minimum bandwidth usage
d. Configure compression for RemoteFX data -- select Optimized to use less network bandwidth
Thanks,
Eleven
