Helped my brother install his next gen Samsung. I checked the resolution for the four available channels. WTHR 1080P, WTHR 1080P, WTTK 1080P, WXIN 720P. The 1080P channels were really sharp.
8.1 and 23.1 info has been missing for several years because of a dispute with Dish and the owner of those channels. Funny that when other channels are in a dispute, Dish supplies OTA guide, but not for these channels.
I get 129 as strong as 110. I just pulled the plug and after the reboot no HBO/Cinemax data. Dish must have flaw in their flagging. Maybe someone from Dish will read these posts
