Does mismatch in HDMI version between GPU & monitor matter?

All will work at indeed the lowest standard of the three (GPU, cable, monitor). This lowest standard has to be enough for driving the resolution + refresh rate of the monitor. Considering you say "old monitor", it's probably not 4k, so HDMI 1.3/4 should indeed be plenty. You can google the maximum resolutions of either if you'd like to be sure, but you should be more than fine, as the cables and ports are fortunately backwards compatible. :)

Hi,

This is a general question, I am not particularly considering any specific graphics card.

If my GPU is capable of HDMI version 2, I have HDMI cable supporting v2 signal but my old monitor is still say supporting only HDMI 1.3 or 1.4, would it cause any major issues like no display at all?

Will the GPU sense the capability of the connected display and downgrade itself to match its specifications?

Thanks.

they all follow the lower standard, in this case all run HDMI 1.4 bandwidth

it'll work with the lower bandwidth, if the monitor isn't 4k, you are fine.

Thank you all for your replies. The point made by TomvanWijnen that it will work at the lowest standard of the three (GPU, Cable, Monitor) clears my doubt now. So I should be fine and can continue to use existing monitor with HDMI 1.3 that supports up to 1080p.

 

This should be fine as I don't require 4k at all.

Thank you all for giving the required insight and with this info I consider it as solved.
