Hi dariusz, thanks for the quick reply. I am having the same problems as gr8pe.
Baseboard
Manufacturer: MSI
Product Name: CSM-Q87M-E43 (MS-7830)
Version: 2.0
BIOS
Vendor: American Megatrends Inc.
Version: V10.5
Release Date: 04/01/2015
Processor 1
Family: Intel® Core™ i7 Processor
Version: Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz
I am currently hooked up to a 1280x1024 monitor via VGA, and the BIOS is the most recent version available by the vendor (MSI). When using RealVNC and going to info, it says "Line-speed estimate: 0kbit/s (RTT ~91ms)". When using UltraVNC, the status window shows "Bytes Received" stays at "76 bytes" initially and then jumps to 94 all while "Bytes Sent" climbs up normally. It seems like the AMT VNC server isn't sending data back? I don't think it's a connection issue, as Serial-over-LAN works to navigate the BIOS and I can see that screen fine.
