Verticle Green [email protected]
 
Ever since the IMG upgrate, I have a verticle green line on the right side of my screen. I did search the forums and saw that this was discussed once briefly, but there was no resolution. Anyone have a clue on how to fix this or must I deal with Verizon. Im on a sharp aquos 32" with hdmi

I also had the problem and I am really upset about it. My neighbor was getting FIOS installed yesterday so I had the opportunity to talk to the guys doing the install. Seems that when they rolled out the new IMG, it is doing this. I understand from the installers (who also have the problem on their home tvs) that they were aware of the problem and were trying to fix it. I got several calls from FIOS technical support including one recorded message that said it would be fixed by jan 23! I wonder if that is true.

Anyway getting back to the issue. The problem is supposed to be associated with HDMI and the new program guide. It gives you the green line on the right side and if you look on the left side you will see the picture distorted, like a beveled mirror, for about 1/2 inch (depending on the size of the screen, mine being only 42"). When you use component cables rather then the HDMI the problem goes away. I did notice the pq gets a little worse when you do this, most likely due to the component connections being analog. While I can live with a "smoother picture" I no longer get surround sound from the tv so that option really didn't work well for me. Another solution (the one I am using) is to go into the stb and change the ouput to 720p. This eliminates the problem with the line on the right and left and also allows me to get the surround sound. The down side that I noticed and that might just be me, is that I am not getting some distortion (or whatever you call it) on fast moving activities. For example, watching the football games, I got that lag which I didn't have when set to 1080i using either the hdmi or cables prior to the IMG change. I did notice the problem only exists on some stations not all of them.

So, until it is fixed, I will leave the box output at 720p and let the tv upconvert it to 1080i.

Hope that works for you

You need to go into the service menu. Under add'l HDMI settings and change the color space to RGB. This will rid you of the dreaded green line.

Yeah I tried those with the same results, but i rather keep my 1080i resolution. As for the RBG, might just be my eyes but the picture did not look as bright or as rich as it does on 4-4-4. So i guess we wait till verizon finds a solution.

Thanks so much HenryFarpolo, I just tried the RGB thing and am tickled pink to get rid of that dreaded green vertical line. Interestingly, switching the setting to RGB essentially turns the vertical green line black, which takes care of the problem in my opinion since the blacks are so deep you can barely tell it's the display and not the plastic side of the TV. However I am not getting the effect that pcsgrp mentioned, the "beveled mirror effect"on the left side of the screen.

I also have a Sharp (LC-32GP1U) and it annoyed the heck out of me that I couldn't set the TV to "dot by dot" setting without getting the green line. Before FIOS I had Comcast cable, and while sometimes I got a thin, bright white or yellow line (which could be on either side of the screen and/or the top), the right-sided green line with FIOS is much thicker (about 3/4 of an inch on my screen). I like to use the "dot by dot" setting whenever possible because it gives you a true, pixel for pixel 1080-line display instead of having the TV crop off a small amount from all sides in an effort to counteract any border lines from the broadcast feed.

One last thing - what's the technical difference between the RGB and YCC 4-4-4 colorspace? I don't notice a remarkable difference in hues/brightness/contrast etc and can't really do a side-by-side comparison since you have to go in and out of the service menu.

Are you guys TV runs on 720p native? If so, try change the resolution to 720p instead of 1080i. By doing so it will get rid of the green bar. I tried on my neighbor who also had this same problem and it worked.

Nope, my TV has a native 1080p display.

Besides, if I were watching a 1080i broadcast on a 1080p monitor, why butcher the resolution by 360 lines, i.e. why have a 1080p TV in the first place if you have to downsample it to get rid of the green line? But I hear what you're saying, it's an option. Personally I'd rather just use the "stretch" option on my TV which, although misleadingly named, simply does a very minor crop around the periphery of the image and gets rid of the green line. Of course this is all now a moot point since you can change the color space option to RGB in the STB menu.

Yeah my tvs the same..1080p native. So am i nuts or has anyone else noticed that RBG doesnt seem as bright or the colors as rich as y4-4-4? If its all in my head i'd gladly change it to that...

HenryFarpolo 01-23-2008 05:42 AM

Besides the RGB option, I forgot to mention that using component cables also gets rid of the green line. The RGB option only applies to HDMI.

You can use both HDMI and Component out of the 6416 FIOS box into the Sharp. Just toggle the input button on the remote to compare the PQ of the two inputs. It is a matter of individual taste. I actually like the PQ from component better, but others may disagree.

Try adjusting Contrast, Brightness, Saturation(color) and tint(hue).

If you are comparing component to HDMI, be sure to set-up the picture settings for component if you haven't used it before. Each input requires it's own settings set-up (at least on my Sammy it does). And I agree with Henry that component gives a nicer picture if set up correctly.

Well, I can now see the "beveled edge" you mention. I can't believe I didn't notice it before, but now that I looked harder it's definitely there and it's too annoying to overlook, especially when there's alot of motion on that side of the screen. What a bummer...I was so psyched to have gotten rid of the green line...argh!!!

It's nice that the component connection gets rid of both the green line and beveled left edge, but then you have to deal with extra audio connections. Probably my favorite aspect of HDMI is that it's a single cable. Less clutter is better.

pcsgrp 01-24-2008 08:09 AM

Right now I am using the HDMI connection and have the stb set at 720p output. I let the tv take it up to 1080p. While the picture quality in HD is ok, I think it was better at 1080i output prior to the uprade. I am going to try the RGB and if that works, if not, I will have to wait for verizon to fix the problem. What I don't understand is that my neighbor just had FIOS installed on monday and he doesn't have the same problem with the green line or the distortion on the left side. I asked him if they used component or hdmi and he looked at me like I had a square head. I will go over tomorrow to see how they did it and see his new setup

njdevls 01-24-2008 02:44 PM

Yeah it seems to be selective with what Tv's it effects. We also have a westinghouse lcd using HDMI and that doesnt have any problems with a verticle green line or the image distortion. kinda weird...

I'm thinking maybe it's that not all HDTVs have a display mode that shows every single pixel included in the broadcast feed (which is called "dot by dot" in Sharps), and those are the ones that won't show the extreme edges and hence the green line on the right and beveled edge on the left...I just hope it's something Verizon can fix and doesn't just try to tell us it's our TVs that are at fault, which I know is B.S. because my display didn't have this problem on national HD channels via my previous cable connection.
