Question How to best interconnect PC, monitor and TV various outputs and input ports

[abngton]

I have spent hours researching compatibility of different ports and their versions, but at the end of the day I really could use some help in making the best decision in this "monumental" port matching.

What would be an optimal way to connect these 3 units to hopefully achieve the 2560 x 1440 at 75Hz at least at the monitor level? (while avoiding the possible HDMI splitter caveats)

My PC (Optiplex 7010, mobo dell 0GY6Y8 ) has a VGA + 1x HDMI 1.4(GPU), 1x DVI(GPU) and 2x DP 1.1 (main board) display outputs.

My monitor has 2x HDMI 2.0 and 1x DP 1.4 inputs
(LG 24QP500-B 24” QHD (2560 x 1440) AMD FreeSync, Refresh Rate 75Hz)

The TV has HDMIs.

Many thanks in advance!

Sad to say it but your best option is going to be HDMI. Here's my opinion on why:
1) Your PC only supports up to DP 1.1 and your monitor capability is 1.4. You could connect these two together at least since the monitor will back-step to 1.1 to match the PC.
2) Your PC HDMI is 1.4 via the GPU and your monitor is HDMI 2.0 which again will back-step to match your PC.
3) Your TV doesn't have DisplayPort at all so that eliminates that possibility totally.

Side Note: They do make such a thing as a 3-way HDMI splitter where each of the 3 ports function separate from each other. I had to get something similar for a couple of machines at my employer because of graphic designers needing 3 displays and only having HDMI.

Thank you hedwar2011.
Yes, I see, forget about DP here...
I've done more digging, and supposedly HDMI 1.4 is able to support the monitor's 2560x1440@ 75Hz, which is my primary goal.
The tv set's inputs are HDMI v1.2a (= another back-step), and I agree with you - an HDMI switch is most likely my best option here. I will do that.
..and by the way, any recomendations for a suitable switch?

Thank you for your kind help!
