Vizio GV47L 47" 1080P LCD Official Thread II - Page 62

post #1831 of 1986
Sorry to be a bother, i couldn't find the answer to this so decided to post. I have my HTPC hooked to the Vizio (ATI X800) via DVI-HDMI 1, and it worked flawlessly until recent. The image from the PC now is shifted to the left about 1 1/2" cutting off the left side of the windows destop and leaving the counter part on the right side. I updated the ATI drivers to the latest, (8.45) but the problem still is there.

Current Settings:
1920x1080P
60Hz

Any ideas on what happened or steps I can take to fix it? Should I roll back to previous drivers?

THanks in advance!

Shawn

Realy..not intended to inflame..just curious if this issue is generic across all brands or if some do a better job of having zero dead pixels?

I have seen many other brands with dead or stuck pixels. We discussed this in the Vizio P50 thread. I did a Google search and found methods to attempt to try and 'unstick' them, such as the pencil massage trick that you posted. There was a download of a computer utility that may help, but I cannot remember where it was, except that the Google search found it.

I would first try the System Restore to a point when it worked. Then try a driver rollback if it does not work. Then try deleting the ATI drivers and software and use the generic Windows driver. If this does not work, download just the Driver from ATI, not the entire utility. That's the exact steps that I would take.

Sorry to quote myself but I think I may have jinxed myself. The front-panel controls on my replacement set are totally and completely unresponsive. They don't light up or function at all.

What exactly is the "re-certification" process? Don't they check these things?

Time to call Vizio yet again. So disappointing - my original GV47L experience was so blissfull....for 9 months.

Thanks DRWAM3, good suggestions, and I'll give them a try and report back.

Cheers

The ATI Catalyst software would sometimes make my display unhappy, so I usually do not install it. There is another driver alternative called 'ATI Tray Tools' that you can find at versiontracker.com, download.com, etc...However, you should visit the developers web site to check compatibility. If sytem restore works, then you may want to try it. If it does not work, use system restore again. Of course, the enemy of 'good' is 'perfect'.
post #1837 of 1986
I took your suggestion and did a system restore, and everything is back to normal. If I have more trouble, I'll take a look at the "ATI Tray Tools" option.

Thanks again!

Don't forget to mark the restore point or keep a note when it was OK.

Congrats! You gotta like when your toys perform well.

Doc.

Drat, the problem persists, everytime the system restarts it wants to take the latest ATI drivers, (8.453.0.0) AND THE PROBLEM with the shifted desktop COMES RIGHT BACK. So I just spent several hours using system restore and uninstalling all ATI drivers and starting from scratch only to find myself back at the beginning several blue screens later. Next thing I will try is to contact ATI support and see if they have any suggestions. I problably should upgrade to Vista anyway, so this might be the time. Oh well, I sure know my way around system restore now!

Cheers

mrtcpip, Vista has some similar problems, so you may want to try ATI Tray Tools and ATI support first. ALso, find a friends copy before buying Vista and try it on another partition just incase it borks your computer. I have a friend that had Vista Home Premium and Ultimate, but the settings on his two LCD's would not stick. They were Samsung LCD monitors. He called nVidia support [useless as she said that she 'did not think that you can connect two monitors to a computer!'] as well as Microsoft support. They could not help. Finally, he swapped the Sammys for two NEC LCD's and has not had a problem since. Therefore, it may be how the drivers recognize the LCD, and that milage between brands differ, so don't spend a lot of money on it before testing. If a friend's copy of Vista works consistently, then buy it.

Bummer. Sorry you have to go through all this. If you can get a decent set, its a great TV. The blotchy thing is definitely caused by the packing material and goes away over 10 days time. Keep us informed.

I agree! Vista is not ready for prime time. Following drwam3's advise is the recommended route. Keep us posted.

I'm having a problem. My set appears to have some smudging or what looks like (liquid) staining on the bottom of the screen. I don't really know how to describe it.

Has anyone experienced this or does it sound familiar at all?

Any help would be greatly appreciated.

Thanks.

Is the smudge physically on the LCD panel or part of the broadcast picture?

Thanks man. The blotchiness did indeed go away after a few days. Anyhoo, I called Vizio yesterday about the front panel controls. They are sending out yet another replacement set. Hopefully I'll have better luck with this one.

Well, my third set showed up today. Haven't found anything wrong with it yet, but I've only hooked up coax to watch cable so far. I did this before the delivery people left just to make sure I'd at least be able to watch TV.

The delivered me another dual HDMI model....which is okay since that's what I originally bought, but a quad HDMI model would have been a nice addition for all my trouble.

Oh well, let's hope this one works out better.

Apart of the broadcast picture regardless of the input I use.

I'm gonna try unplugging it and leaving it off for a while and see if that helps.

It's difficult to diagnose a "smudge". Can you be more specific or post a photo?
post #1849 of 1986
Anyone here know about the firmware update for the GV47L?

I was told by Vizio support via email that a customer installable f/w release would be ready in Feb 2008. February has come and gone and March is almost half over.

The issue gone now. It's very bizarre.

I guess when in doubt, just unplug it.

Thanks!

Did they say how you would get the firmware? Was is downloadable on their website?

Can you post the email to this site? That would be helpful.

What is it supposed to do?

Address the audio lag issue I was told by Vizio support via email about a week ago. Not sure if there were other issues addressed.

Then this....

Entered a support request on Vizio's web site on the GV47L f/w issue yesterday and the reply I got today was there were no pending f/w updates at this time.

Are we confused yet?

No, not yet. That F/W update would be enthusiastically received. On my Dish 622 DVR there is an option to sync audio to HD or SD but it doesn't seem to do much of anything.

There is not one Vizio that will display 1080p/24fps native. It will accept it and convert it to 1080p/60fps using 3:2 sceme. But will not display a native 1080p/24fps.

Yes it is 60 rather than 24fps. My mistake. Thanks for the correction.

Hi Guys, me again..

Against all the good advice regarding my horizontal image shift issue, and all the problems I had with the ATI drivers (and ATI Tool tray did not fix the issue) I decided to upgrade to Vista. Actually, the upgrade went well and the new vista ATI drivers for my Radeon XT800 fixed my previous issue. All was well for several days, now I have a different problem I am trying to diagnose and fix.

I am feeding the TV from the ATI card with a DVI/HDMI cable to HDMI 2 on the Vizio. If I turn off the TV, or switch inputs, when I return to HDMI 2 input I get no signal or picture. (the TV is blank, and no synch to an incoming signal, it acts as if there is no signal) At first I thought it might be some power saving option in Vista, so I set my PC to never turn off display. The problem still exists. What is strange is that this problem did not exist after the upgrade but surfaced several days later.

One other thing to add, it seems like a PC / video card issue, because if I remote into the PC with VNC (remote desktop application), I get no desktop, the display on the remote computer is blank also.

Any ideas? It's a mystery to me..

Thanks in advance!

Shawn

I've done some searching around and it looks like I am experiencing the dreaded, SDS ("Sleeping DVI Syndrome") and from what I can tell there is no current fix..nice. Some folks have fixed it with reinstalling vista. I will try setting the screensaver to off and resetting the power options to default and if that makes a difference.

I'll check back with findings as a transverse the classic FPTF (frying pan to fire) chasm.

DID it work? If XP was better, can you set up a dual boot system. It can be done, but if you try, you should read about it first.

I haven't followed this thread in a while, but do they have a version of this model with 4 HDMI inputs?

And a quick question: would it be worth it to wait for the 120hz models coming out in the summer or is this model still the best bang for the buck from Vizio?
