Will this help if I have Downstream 39.1 dB SNR, -8.3 dBmV Power and Upstream 48.0 dBmV ? My particular challenge is we have a handful of channels that either won't show up or are highly pixelated for a single TV. The channels come in fine with our other TVs.

I used it for the cable modem connectivity, not channel quality and it worked for that.

My experience with his booster has been very positive. It pretty much solved my problem (which was similar to yours). The trick is to put it as far upstream as possible... where the signal strength is adequate (can't boost a signal that isn't there). It sounds like you have a good enough signal coming in, being the other TVs are getting a solid picture. I'm guessing the "problem" TV is at the end of a long run. You might be splitting things up too much, so the signal strength is dropping below the muting point. .. this amp should solve that. Good, solid product.

You've probably made a decision by now, but I'll answer anyway. Yes, it will improve signal power levels, but it's unlikely to improve quality with such a high SNR already. I'd leave it be unless your cable company suggests that your return signal needs improvement. You'd likely end up with a +7 dBmV, an SNR of 35-38, and a return level of 38 dBmV.I'd see if your cable company can come troubleshoot the signal first. Amplifiers should only be used for low signal at the point of entry or for a home with many outlets and splitters.

It had problems with my Directv Box. It would display the video initially, but when changing the channel to one with a different video signal (1080p channel to 720P channel, etc.) the screen would take 5-10 seconds to show the video if I was lucky, but most of the time the screen would go black and I could only hear the audio. It worked great with my PS3, Xbox, and PC.

I know exactly what the issue is. There is a setting on your cable box/sat box where you tell it what resolutions your TV can support. Some cable boxes allow you to pick multiple choices (e.g., 480p, 720p, _and_ 1080i at the same time). What happens in this case is that the cable box will automatically output the signal at the native resolution of the broadcast, provided it is on your selected list. This usually results in the cleanest picture, but of course it causes your TV to have to change resolution modes to match the input every time you change from a channel with one resolution to a channel with another resolution. On my Samsung DLP, I chose to put up with this constant switching because it resulted in the cleanest standard-def picture (my cable box sucks and upconverting SD signals internally). However, if it bugs you, just set your cable box HDTV menu such that your TV only supports 1080i. The result will be that the cable box will internally upconvert all broadcasts to 1080i prior to sending it to your TV, and your TV will no longer have to switch modes all the time. Hope this helps!

Yes, my experience is that the lowest resolution of any TV output (destination) is the prevailing resolution for all other TVs on the splitter. I make sure that all my TVs are 1080 resolution and that my source is output at 1080p. Any 720 resolutions TVs should be sold or used in isolation from a splitter since it will send that limitation information to the splitter which will then send it to the source causing all other TVs to receive the lower quality signal.I had heard that only the first TV turned on may be the prevailing resolution, but that just means your 720 TV may not work. In either case you should consider removing that TV from the splitter.

I just took delivery of my 550, and I immediately saw blurring while watching hockey (and some on basketball). It's as if the TV is going in and out of focus very quickly, and it's very annoying. I'm pretty sure I'm going to send the TV back, but really need to know if anyone thinks this issue goes away with the 120 hz models. If so, I'll trade up. Thanks.

Ya im really worried that the feed from my blu-ray player is causing the issue because when i have the player off & its running through the receiver the background is dark black with denon displayed on screen like it should be, then when i turn on the bluray palyer im back to the side lighting isssue. I have a ps3 so i will try it but that means I lose all my hd sound due to the limitations of the ps3. :(

The splitters (2) that I tried at the input end would not work - the signal strength was too low. Just for interest I tried a splitter at the other end and zero signal. Also at the output end, even some 90 degree elbow adapters or HDMI keystones would drop the signal enough to be a problem. Bottom line is the cable is good, just have not found anything that is not a drain on throughput.

Not sure,it turned out the bsllast I bought was not the problem.ended up giving the tv away..sorry I couldn't help.

Thank you for the replies! So, I shouldn't worry about having to return the tv?? Do you think it could be an issue with the cable box possibly? Or, is it the TV? The line that I see doesn't go away, and is in all modes.

I don't know what it will pick up, up there. You will need to get an inline booster. My channel 7.1 through 7.4 comes in good all the time. My channel 21.1 through 21.4 don't come in to good all the time, at night better. But I did not get any channel 21 before. I think I probably get couple other channels that I don't watch. I went on another site to see what channels, antennas would be out there, and how far away they are. And then pointed my antenna in that direction. Had to play with the ears, and antenna direction to get to work better. I hope this will help you make up your mind. I have not done anything to my antenna, but I have been thinking about screwing a bigger base on it.

A similar thing happened to me in which some channels did not work. It seems that if you use cable splitters, the signal gets attenuated causing some channels to be received intermittently. When I plugged into a cable line without a splitter and with a short cable to my AverMedia device, I was able to receive all channels. A cable amplifier may help.

Tom, Like you, have a Samsung HD cable box from TW. Connected HDMI to my Pioneer Plasma. Problem I am having is when changing HD channels picture is scrambling for about 5-10 secs before coming in. Analog stations change without a problem, just in HD. I switched out the box twice, same problem. Had a techinician come over, he switched out the box again, same problem. Put the component connection and works fine. Tells me it's the monitor. Pioneer says that's ridiculous, it's the cable box. I have been reading numerous threads about this problem. It's the TW cable box, it does not have the proper software to support HDMI. You have to call TW up and complain and see if they will fix the problem. R

My unit don't even work DEAD on arrival. look elsewhere.I think the 3d media units only support 1080p in side by side. Ask the question in AVS forums.

In all likelihood your set is fine. Your DirecTV tech however needs a refresher course. Your satellite box is putting out a 4:3 ratio picture (that's four units wide for every three units high) while your TV is displaying a 16:9 picture, resulting in the black bars on either side. I don't have this particular Vizio, but my Samsung has a setting to enlarge (without distorting) the picture where the image will then fill the screen. You lose a bit of the top and bottom of the picture, but it will fill the screen without distortion. Your Vizio may, or may not, have a similar setting. There may be a setting on your DirecTV box to change the output to 16:9, but I doubt it. I suspect you'll have to wait until you get the hi-def box. There's almost certainly nothing wrong with the TV however. By the way, if you have an old pair of rabbit ears (or an existing antenna) and you live remotely near a television transmitter, you might want to try connecting the rabbit ears/antenna to the TV and scan to see which channels you can get. Very often the absolute best picture quality comes from an antenna.

D. Mauro, Different signals and devices will vary. The good news is that each input is independent, so it's designed so that you can set each input to "Clear" or "Smooth" or whichever setting you most prefer for that specific input. This way, every time you switch to a different device, you don't have to change your settings. Why it's juddering? It could be signal strength or more specifically, signal compression that causes that. For some networks - or hardware - the signal needs to be compressed, and decompressed. That can have an affect on the playback. Or it could be a number of other factors as well, like the resolution that's incoming (480 to 4K, 720 to 4K and 1080 to 4K will all look different), so check your source's video menu (Blu-Ray player, Cable/Sat box, etc) to make sure you're getting at least a 720p or higher resolution, or that it's set to AUTO. Those factors can also affect picture quality. It's probably NOT the cable, we can probably fairly rule that out. Does that help? --Mr. S

Matt, thanks for posting this. I had the same question and couldn't find an answer. Is it possible that the latency the reviewer perceived is due to upconverting the signal to 1080i, and you are simply converting the analogue to digital signal without changing the resolution? I'm not clear on whether converting implies *up*converting, couldn't really find an answer... but based on your feedback I think I'll give this a shot.

hi justin, you might alos check the right output from your source. had the same problem with the tv. albert
