I have had the same problem with a Samsung tv. Manually selecting the available resolutions fixed the problem as you found out.

Something has to upscale to the native resolution of the screen and it can be either the V6 or the tv. I found that the tv was faster and had a slightly better picture when the tv did the upscaling so I let the tv do the work instead of the V6.

I do find from time to time that the V6 goes back to automatic and flickers again but going through the process of selecting all resolutions fixes things again
