Hello. We’re new here, having purchased our first Tablo – and having finally cut the cord – earlier this year. We’re here hoping that someone who is knowledgeable about how digital TVs & signals work might be willing to help us with a problem I’m having.
We have two TVs that we watch, one in the bedroom and one in the living room. Our Tablo device is connected to a Roku in the bedroom, and we have another Roku in the living room.
The picture quality on our TV while streaming programs will decrease during cut scenes or fast-moving video, to the point where the entire screen is made up of small, equally-sized monochromatic squares. This effect is fleeting, lasting only a fraction of a second, but it happens frequently (more often than once a minute), after which the picture quality reverts to acceptable quality until the next incident.
This problem occurs no matter what we’re watching. It happens if we watch programming recorded by Tablo, and it also occurs if we watch programs that we are streaming through our Roku from Discovery+, Hulu, Netflix, or whatever else. So this does not appear to me to be an antenna problem.
It seems to us that the issue is likely one of the following:
- Our internet service is too slow, so the signal making it to our TVs is too weak;
- The processors in our TVs are too slow, making it so that the TVs cannot draw the HD content quickly enough; or
- Enough signal loss is occurring in our internal delivery system (either WiFi or Ethernet) to prevent the TVs from drawing the HD content quickly enough.
We’ve attempted to troubleshoot these three as follows:
- Today we upgraded the internet service being provided by our local cable company (Comcast) to the fastest that they offer. We upgraded from download speed of up to 200mbps to download speed of up to 1200mbps. This did not affect the problem.
- We have two different TVs of varying quality that seem to experience the problem to the exact same degree, which to us implies that the TV processor is not the factor causing the problem. Additionally, we tried watching a Discovery+ program on one of our PCs and observed the same pixelization on the computer monitor. The PC used is a gaming PC approximately two or three years old, with a good video card, so we don’t think the problem is processing power.
- Over the course of the past few weeks we’ve tried both WiFi and Ethernet connections and switching from WiFi to Ethernet, or vice versa, doesn’t seem to affect the problem.
So, after all the troubleshooting that we have tried, we have been unable to affect this problem at all. I’m not a technician and have been trying to find a solution just based on logic, or articles I’ve read on the web. So please be forgiving if you think me ignorant.
Can anyone provide any suggestions for other things we can try?
We realize that a Tablo forum is not the ideal place to go for more general types of issues like we are having. Perhaps if it was inappropriate to create a topic of this nature here, could someone suggest a forum elsewhere that might be appropriate?
