Default Poor HD Picture Quality

I just made the switch to Verizon from Comcast and immediately I noticed a poor picture quality on the HD channels. I find this strange since all that I have heard is that Verizon's HD is better.

I notice a grainy look mostly in the background. Things focused up close on the screen are clear, but the background is grainy. In the case of sports, the wide angle shots seem to be grainy as a whole. This becomes especially noticeable when there are solid blocks of bright colors (red, yellow, orange etc.) When there are large blocks of these colors they not only appear grainy and out of focus, but the pixels almost seem to be moving if that makes any sense.

The only difference I know of is that on Comcast I had component cables, and with Verizon I have HDMI. There is a second TV in the house that is clearer than mine, but still having an issue with looking grainy.

Any suggestions? I have heard that verizon's HD is better and I'm looking forward to seeing it for myself.

With a new signal you may need to adjust your tv's settings. I don't notice grain on my HD channels. Also there could be some problem with the wiring or hookups so you may have to get FIOS back to your house for checking signal strength at the boxes, etc.

What clearday said.

It sounds like your sharpness control is too high. You might even consider professional calibration for your set which is the only way to maximize performance.

As an update FYI... verizon tech came out this morning and tried everything. Replaced the coax cable, replaced some stuff on the outside box, replaced my dvr box, made sure signal strength was full etc. He acknowledged the problem with the clarity and he left me saying there was nothing he could do for it. Sometimes that "just happens". Needless to say I'm not too happy, my HD picture with Comcast was fine.

My television is a Phillips if anyone is wondering.

Not sure if this has anything to do with your problem or not, but someone in this area started getting a really crappy picture. He was adamant that Verizon's PQ just deteriorated, and his neighbor's saw the same thing. I live about 5 miles from the guy and my PQ was great. After much going back and forth with Verizon, it was discovered that the problem was with the fiber feeding his neighborhood. Apparently it had some dirt on the end.

Clearday is on target. You are seeing artifacts of the digital signal being "overprocessed" on your set - especially visible now b/c (a) you are getting a better signal from VZ to begin with and (b) you are transferring that signal to your TV thru a better wire (the HDMI). You should be able to solve this problem using the picture contrls on your TV - start by adjusting the sharpness down. See also these links for more suggestions:

Default poor hd picture

I am experiencing the samepoor HD picture quality. My HD looks about the same as SD looked like with Comcast. The pictures seems clear in a closeup with no movement. When the shot is farther away, things are not clear. There is a lot of grainyness in dark areas. VZ has reset he box twice. VZ sent a new QIP 6412-2 STB with same results. VZ techs came out to house and verified grainyness. They replaced the STB again. Replaced the MB in the ONT. Place an attenuator on the coax. Cleaned the fiber optic cables. Still picture is grainy.

It seems the STB can not process movement quick enough.

I have adjusted picture setting on the TV to all different configurations.

Comcast picture was crystal clear, Blue Ray is crystal clear, but verizon grainy.

Any suggestions?

I too came from comcast a while ago. The fios hd picture was as good (and maybe better) than comcast at the beginning but I have noticed graininess since V* added all the new channels.

I'm pretty sure V* is down-rezzing pq (although I have no proof of that) in the short term but hopefully it will be back to an outstanding picture once the infrastructure catches up.

I am happy overall with the additional channels and cost savings I get with V* and will put up with the decreased pq.

Now, if comcast catches up with the amount of HD content and lowers their price - who knows.

But for now, I think V* offers the best value (IMHO).

Check your display mode setting.
I was just fishing thru the menus and found mine had been reset to 480i.

Default Poor HD pic with FIOS

Same thing for me. FIOS worked fine on all my conventional TV's. Dramatic improvement on a new cheap ($600 panasonic 720i LCD) hi def set, but it is a good bit worse on my $2200 (3 yrs ago) SONY LCD Rear projection which had stunningly good and accurate pic quality with TIme Warner. Verizon has been out here tried wire switches etc to no avail. I read one thread somewhere about some TV's are treating the signal as uncompressed (MP4) instead of compressed which sounds logical but who knows. Pic is darker, smudgier and lacks the the fine detail and color accuracy. Choice seems to be go back to cable or live with it so far.

Go to menu -> settings -> video and make sure you are outputting 16:9 and also that you have the resolution set as close to the native resolution of your TV as possible, i.e. if you have a 720p TV, set the resolution to 720p, if your TV is 1080p, then set the resolution to 1080i. Also, I had a problem where my DVR box would default to 720p every so often. I fixed this by going into the service menu and made the default setting 1080i.

Default FIOS Issues with HD

As was the case for many below, the installation of FIOS resulted in poorer HD quality than I had with Time Warner on my main, high quality HD set.
Main set is a 3 yr old SONY LCD rear projection which had outstanding HD quality with cable. PIc is darker, smudgier, poorer contrast and colors a bit off to the green side. Had been PERFECT with cable.
Other TV's in the house, including an inexpensive new LCD 720i model from Panasonic are excellent. Had one visit from Verizon to correct, did mostly cable work, no luck.

That's what I'm thinking too. Trying switching to component cables and see if it's any better.
