Helo guys.

Whats the difference between both VGA HDMI and VGA USB.
Performance wise ?

Thanks in advance.

If you are talking about HDMI>VGA and USB>VGA, the performance limit is limited to output port, not the source port. So, in this case I believe 1280 x 1024 is the max resolution due to VGA limitation.

Both reported to have problem with certain monitor/hardware. Anyway, VGA carries only video. You still need separate audio source. I would go for USB>VGA because USB port is more common

seen the performance of these converters and i can tell you im not impressed.
HDMI > VGA is very hurtful to my eyes.
i dunno how i survived EVGA monitors last time

So you prefer HDMI > USB ?

i cant say i have not seen it before.
