My Samsung SyncMaster 913v (henceforth "913v") outputs VGA. Thus I need a VGA-to-HDMI adapter to connect it to my Lenovo Ideapad Y700.
In Dec 2016, I bought VicTsing Gold-plated HDMI to VGA Converter Adapter. In Sep 2018, it failed, and then I bought VicTsing HDMI to VGA Adapter, [ Upgrade Version ] 1080P VideoGold-Plated Converter, but the 913v's top and bottom were cut off. Thus in Oct 2018, I tried another adapter: Rankie HDMI to VGA Adapter. But the cutoffs remain:
VGA monitors do not fit the picture "natively" to the panel. Because it is an analogue signal the monitor needs to detect the edges of the picture to find out where it starts and stops. Analogue (VGA) signals have a "lead in" and "lead out" at the top, bottom, and sides so that whatever is receiving it can train on the signals and make sure they have the full frame.
You need to press the "Auto" button to tell the monitor to scan the picture and align it to the frame.
It is useful to have a full screen image on screen before pressing this button.
