My K-1 ii LCD is "grainy" in very low light situations like astrophotography.

I use live view to manually focus and reposition my camera during astrotracer sessions. I did not have the grainy LCD display with my K-1. You can see the difference in the attached photos that I made with the same settings and with the body cap on to simulate a dark sky. The LCD works perfectly except in the dark. Is there a setting that I need to adjust or is the LCD defective?

The OK LVQ in the lower right hand corner of the K-1 ii LCD display disappears in a second.

The LCD isn't defective, the noise is because it's amplifying to very high ISO in an attempt to show something in no light. In Bulb mode the camera isn't showing exposure preview in live view, it instead switches to trying to show some exposure that's viewable; same when working with manual aperture lenses. Some of the other camera brands allow you to toggle between these behaviors, but I think Pentax goes to one setting or another depending on the mode.

With the K1-II, focus peaking is probably on and on the K1 this is switched off

I think there must have been some setting differences between the K-1 and the K-1II as previously mentioned. I've seen lots of "grain" on my K-1 when using Liveview in low light so seeing it on the K-1II is no surprise. If you have the ability to set the two cameras side-by-side and with identical settings, they would probably be comparable in this aspect, though I may be wrong not having the K-1II myself.

Focus peaking on the K-1 ii was the problem

Just a reflection of ambient lighting.

Switch focus peaking off. Did it with mine, now it's much easier finding stars
