ASI2600MM subs looking strange

Hindsight

This happened the other night. I've not seen it before. I have the latest drivers installed, and also ASI Studio. Whether I imaged with NINA or ASI Studio, the results were the same. With a screen transfer function stretch, the image appears grey. If I manually change the stretch, the image has a pixel-to-pixel grid pattern. I power cycled and re-booted the camera and PC multiple times that day and nothing I did fixed it. Then, the next day, it started working fine again. I didn't touch or change anything (cables, etc) and it's installed on a permanent pier. It has a high quality 12vdc power source and high quality USB3 cables and power cables. All of which have been in place for several months and working fine.

.... and the next day after it worked fine (today), it started doing this again. Even bias frames look strange like this.

Here is a bias frame taken from when the issue was taking place tonight:

Please make sure that the USB port you are using provides adequate power and data bandwidth. Although your cable is of high quality, you can try changing to a different USB port or using an externally powered USB hub to see if this resolves the issue. If not, you may need to return the cable for repair.
