My Video Card is: MSI Gtx 1080 Ti Armor OC
Can i use 5m extended cable HDMI v2.0b with my Pimax 4K?
Basically each and every cable should work with with 1080p resolution in piplay settings. 1440p requires good cable, i cant advise any as i always used my 4k in full hd.
It does say it can feed a 4k signal so should handle 1440p. If it doesn’t then I would be sending it back… But the description does sound like it should work.
My pimax resulotions is now 1440p X 2560p per eyes with hdmi extended cable v1.4 5m with a good hdmi repeater v1.4b but it must be 1920p X 2160p per eyes. For it i will change hdmi cable as in the picture.because this cable hasn’t got limitation for 4K. it will may be not work. i don’t know. i will just try. But i saw a friend in this forum he used this cable but his cable is Hdmi 2.0a. i don’t buy this one because i think 2.0b better than 2.0a. Am i right?
4K*2K Repeater and Male to Female Active HDMI/USB Extension may be all that’s needed but it wasn’t so on my side (flickering/no display)
Had to revisit this some time ago after setting up Vive Tracking on the Pimax 4K.
All of this is connected and working with 2560x1440 enabled:

For my 4K, I bought

along with a male/male extension cord of 2-3m.
My Odyssey didn’t work with the repeater, so I bought
Should test if the 4K works with this too.
Blaz My friend i don’t understand you please explain it good. Which one is worked? Club 3D’s Male to Female Hdmi Cable or Deloc and male to male Hdmi Cable on your Pimax 4K?
I am so sorry for my english is not good to understand you well.
Okey now i understand you i am very sory for that man 
Your Samsung Odyssey doesn’t work with deloc hdmi repeater and hdmi cable male to male and you bought club 3D male to female and this was worked and you did not try this Club 3D’s hdmi cable on your Pimax 4K yet. Am i right?
if this cable worked my cable will work too bacuse they have same tecnology. But your cable is litle bit more expensive than my cable and short. My cable is 5m. i bought it from aliexpress and it will takes to come to me totally one month 
Yes, you are correct. I can definitely say that without a 4k repeater, a standard hdmi extension cable will not work for your Pimax 4K. But technically, a high speed 2.0 HDMI extension cable should. Will test mine this weekend!
Thank you man i am waiting for your test if you will share your experience on this platform i will be very happy thank you again. Good Luck!
I can definitely say it works. Will see if performance is impacted.
