yeah most all of them are good to -30c easy, as with most electronics, just make sure it stays dry and let it sit inside to acclimate for a few hours before you turn it on.
when very cold rubber and wire insulation might crack if moved, but sitting stationary it’s fine.











I will take a guess that you won’t have any image lag issues whatsoever.
Pretty much all displays have imperceptible lag on actually displaying an image- a lot of consumer flat screen TV’s are terrible at it because of their controller being shite or intentionally lagging the image to do frame interpolation or some other kind of background processing. Older analog screens don’t do any of that, they get signal, display signal.
