Thanks for posting.
Have a look over this thread for some useful tips form Andy.
It might be worth monitoring your Internet speed using speedtest.net when you see the quality drop as the picture will adapt depending on your Internet speed.
You can also try these steps to help stabilize the connection to the router that could also be causing an issue.
Any chance this solution can be shared? My internet speeds are approx 28mbps on fibre and our picture quality switches from HD to fuzzy (almost unwatchable) with monotonous regulatory every 5 minutes or so. I've had now tv for 2 years or so and its getting worse. Any bright ideas?
You're probably not going to want to hear this but... A wired ethernet network connection (even one that uses Powerline adaptors) offers a much more stable and reliable video streaming experience.
If you post your ISP and Router model then hopefully forum members familiar with your Router and ISP can offer some further assistance.
I am guessing you have tried rebooting both your router and nowtv device and also tried changing the router wifi channels to see if there is any improvement ?
I'm having the same issues via the Roku stick on an LG Tv but also through the white now to box on a different make of to. Everything has been unplugged, rebooted and installed again and still no luck. The picture quality is so poor that it's not watchable.
It would appear that you have already posted your issue within the forums dedicated 'Roku' area. This is the forums 'LG (app)' device area...
I really thinking of ditching NOW TV, the picture quality is appalling, blocky and pixelated like some bad 80's video game!
I give up on some programs or films because it often is unwatchable, or ok for a few mins then bad
It's not my broadband connection or speed, because all other ondemand channels like Channel 4, 5, youtube etc are fine with great picture quality...
Now TV really need to sort this issue or I think they will lose a lot of customers...
