Where is Firmware for Displayport 1.2 to HDMI 2.0 UHD (CAC-1070)?

8 replies

This adaptor isnt working. Where is the firmware update and instructions so i can try that before sending it back?

Please provide additional info on your setup and current FW version so we can look into it. Thanks!

According to my sticker on the adapter I am running CAC-1170 Rev A1-00, FW 7.1E 1613. I cannot get 4k@60hz from either of my TVs (Sony XBR55x850 and XBR43x430) both which support it. I have enabled the Enhanced mode on the TVs as instructed, but when I apply 4k@60hz the TVs display "no input." Perhaps the firmware update will resolve this issue? I've attempted this with two MacBooks 15", both support 4k@60hz using SwitchResX, and my cables are all HDMI2.0.

Please advise before I am forced to send this adapter back.

KPHS, This adapter is supposed to work, 4k 60Hz, from DP1.2 to HDMI 2.0.
I have not yet got it to work.
Did you find any other products that might work ?
thanks

In the meantime ill stall the expiring return limit by ordering a replacement I guess since speed isnt a priority here,,,

 I have a computer. It has a 390 dual core devils 13. My one monitor is one of the vizios 10+ other people needed the firmware to fix. 

VIZIO P502ui-B1E 50" 4K UHD 2160p

Windows sees it but no picture appears only on the 4k HDMI slot. These sets were marketed pre-HDMI 2 and have their own "thing" but clearly others say it can be done with most models with the firmware update. They all require this im assuming. HDMI2 is pretty scammy I dont blame them.

Which is the version of last firmware for cac-1070 rev 2

Latest firmware we have ends with 0x26
