I have Roku purchased in the US and using it on Sling TV subscription ... everything is HD and plays smoothly on a 50Mbps PLDT Fibr ... not worth buying the Roku from PLDT and watching Cignal channels, first off, the Roku model they are providing is very old and does not support 4K UHD, and Cignal on IP network is not stable ... Cignal on dish is the way to go if you prefer Cignal
