Poor picture quality with Quantum TV

I just upgraded my service to Quantum TV (one VMS and 2 clients) with a new Fios Quantum Gateway router and the picture quality on all 3 TV sets is now worse on HD stations--as if the picture is at a lower level of resolution, less detailed, less sharp. A tech came to my house and was perplexed saying he never heard of such a problem and essentially said tough luck.

Any ideas?

Can you provide more details?

How is TV connected to box? Component? HDMI?

Have you tried swapping type of connection on one TV to see if it makes a difference?

What is box set to for output?

TV is connected via HDMI cable, of very good quality, on all 3 TVs. I have tried the various diagnostics on Inhomeagent and spent over an hour on the phone with tech support which tried various fixes including switching from 1080p to 1080i, which made no difference. I've tried disconnecting the router and all devices and then reconnecting them. The tech who came to my house checked the RF level at each TV and the signal strength at the outside FIOS box. All were in the acceptable range and yet the quality of picture is definitely worse than it was with the legacy boxes and other router.

I don't know if this problem might be solved with new splitters or a new VMS box. Fios tech support seems to be completely at a loss.

Last night an excellent Verizon tech came out to my house and solved the problem by: installing a Moca splitter--which should have been done by the first tech--and replacing the ONT and replacing a bad connection to the ONT. What's distressing is that not all tech's are properly trained and neither are their supervisors.

Hi All,

I've just upgraded to Quantum Internet and TV and experience absolutely the same problem. Finally gave up chatting and speaking with Verizon tech support and searched for a possible solution online. Found this topic.

Knighty, can you please provide more details regarding the fix that finally helped you, so I know what to request from Verizon? Was the problem with the old splitter / ONT or both?

Did they replace the ONT box with a different model, or the same model but the newer one? What kind of splitter they installed? 2 way or 4 way?

Any help would be really appreciated, as they added a couple of tens of dollars to my bill, but in return I got worse picture quality.

Thank you in advance,

What happened

We've just upgraded Verizon FiOS to Quantum 50/50 Internet and Quantum TV. As soon as the equipment was installed and new services were activated - it appeared that picture quality on HD channels is not even close to what it used to be with the "plain" (not Quantum) FiOS.

Symptoms

There is almost no difference now in SD vs HD channels, rather than frame size and height to width ratio. HD channels look just a little bit better than SD. The difference is most obvious when watching sport channels: small moving objects - such as soccer players - look as "fuzzy" as in SD; when a camera moves fast from one end of a hockey ring (which is a big white space) to another - it looks like there is some kind of slightly "dirty" tail or cloud moving along with the camera.

Setup / connection

First of all, it is absolutely the same as before the upgrade (and again, it was just fine a couple of days ago, before activating Quantum services). I have my only STB connected to the TV through an HDMI cable, supplied by Verizon. A splitter is installed just after the ONT box. I replaced the splitter with the new one provided by Verizon - no difference. Tried to switch back to the old (not Quantum) STB - picture quality is as bad as with the new STB. So, it looks like the problem is either on Verizon's end, or with the ONT (not with the STB itself).

What to do?

Spent a couple of hours chatting and speaking with Verizon tech support. As you can imagine - no luck. We checked all settings (such as video format, sharpness, etc.) a dozen of times. Everything is just fine. They said they checked the signal strength - it looks good to them. I tried to find a solution online and found this topic; it looks like I'm not the first one experiencing this problem and in the case, described in this topic, they had to replace ONT to get rid of the problem, My ONT is 7 years old. Should they upgrade it along with switch to Quantum? Are there any other ideas?

Thank you in advance.

I have had Quantum for over a year now and recently purchased a Samsung KS8000 TV. The picture quality now looks horrible on this set when watching FIOS. Macroblocking, frame stutter, etc. I just troubleshot with a tech over the phone and they do see some signal loss on their end. I have a tech coming out on Saturday. Fingers crossed they are able to resolve the issue. It's like these newer sets really expose the signal quality issues. I was chalking it up to signal compression but someone else stated that FIOS does not compress their HD signal. Is this true? I am going to check the QAM broadcasts tonight when I get home.

No, not resolved. I was told would have to go back to legacy boxes but that adds more monthly fees. May do so eventually. What about you @layzzzee8

I have an update. I wanted to upgrade my speed to 100/100 but it was no available to me as it was not cost productive for Verizon to come out and switch me over. The rep I had on the phone upgraded me to 300/300 to initiate the truck roll and would then lower me back to 100/100 a week later. The tech came out, switched me over from BPON to GPON and the picture is now back to being as crisp as it was with my legacy boxes. I would check and see if you are on BPON and if you are consider doing what I did. If they didn't run an ethernet cable from the ONT to your router for data then you are on BPON. If you are on ethernet you may still be on BPON but you can only find out if you look at the model number of the ONT and do some googling.

I am in the exact same boat as you. Couldn't wait to see what my new 65KS8000 would like like. Until I saw it. Horrible. Tried every **bleep** setting and nothing fixes it. It looks like a choppy painting with little to no definition/clarity. So the only fix is to request from Verizon an older box? What garbage.

Me and my buddy just moved into our place and had fios come in, we just got a 65" Samsung ks8000 with quantom dot display and the picture with fiod hd is bad. My cousin in law has a sony 65" with the new fios boxes as wel and said when he went to buy his the guys asked him what service he has and when he replied fios the salesman said samsung tvs and fios do not go well together for some reason to do with newer samsung tvs being too good for the quality fios is providing and advised to go with a Sony. Fios should address this issue and get ahead of the ball because everytually everyone will buy a 4k tv and if this doesnt change everyone is going to leave.

First, how has not everyone noticed each poster on this topic with issues has the same TV model...KS8000?? And also, missed the whole post about having Ethernet run directly from the ONT in addition to the coax. My tech just last week said the Ethernet must be run in addition to coax for quantum speeds..100/100, 300/300, etc. If you have these speeds and don't have both an Ethernet and coax going IN to the back of your Quantum Gateway, could very well be your issue. I don't know what BPON and GPON are but that dude said switching fixed his same issue. Check out his 3rd to last post!

I've been dealing with horrible quantum quality for a while myself and I can say that upgrading to the new FiOS one boxes changed everything. Amazing picture and UI experience. Since they are 4k boxes, they can be set to 2160p.
