CAC-1070 is flicker and unaligned randomly

5 replies

I bought CAC-1170 from Amazon.com. My machine specification is:
- Lenovo ThinkStation P900, Xeon E5-1603 V3, 16 GB RAM
- Video card: Zotac GTX-750 2GB
- Monitor: LG UF770T UHD TV

CAC-1170 can convert DisplayPort 1.2 signal to HDMI flawlessly. I set the resolution using Nvidia Control Panel as 3840*2160p 60Hz 4:4:4. However, the card somtimes display some flicker & noise randomly. Sometimes, the display is unaligned with the screen position. This annoys my using the product.
How can I fix this problem?

Hi, I've got similar issues.
Specs:
- Acer Predator 17 notebook with GTX980M gpu
- TV: LG 49UB820V

Sometimes display is unaligned (or some colors only), it shakes strangely or flickers. I've used two separate HDMI cables (also one of them was completly new, just out of the box).

Also, I had a similar problem when I was using a AMD 280X but it wasn't as common, there was no popping sound and if I turned the TV off and on again it would fix it. With the Fury's I have to restart my PC to correct it.

My CAC-1070 has label as REV: A2-00, FW: V7.2.3, 1615.
I got the new firmware from [email protected] and now the problem is resolved. Please contact them for the new firmware.
