wobbly graphics

[billyo]

i can add an external monitor on my laptop and i don't have any problem with the graphics, but if i connect it to a tv it will work for about 10 minutes and the graphics starts getting wobbly..i don't have a video out on my laptop so i am using a video tuner with a video out..can someone tell me what's wrong ..or do i have to get a new laptop..

What do you mean by Wobbly?

I have never heard the Video referred to this before. What are the graphics doing exactly? If you are using it and it is working correctly on the second computer monitor, it should then also work correctly on the TV, unless the output that is going to the TV has a problem.

What type of Laptop is it, model, and what Video card is in this laptop?

[billyo]

I have a Dell Inspiron 1000, with 512 MB and 40gb..what i mean was that the graphics start to get wavy after 10 minutes..it only does it on my tv,and doesn't do it on my ext. monitor.

he may need a converter from the shack.

[mindonstrike]

If it works for any amount of time it would not be something a converter would fix.
I would first suspect a bad tuner. Maybe it, or something in it is overheating after 10 minutes. I'm assuming some kind of external tuner (also assuming you don't mean FM modulator). Would also suspect cable from laptop to tuner or cable from tuner to tv.

If your tv has svideo or rca inputs you could probably use a vga to rca/svideo adaptor and go straight in.

I am having a different, but similar problem. I am using a sony laptop to run my show, with dual display to a tv (wal-mart el cheapo) and the slip screen dual display works just fine. It only when I try to send the signal into the RCA video input on a plasma screen the bar has mounted on the wall that I run into problems.

When I split the signal and run to the plasma, the video is all wavey like the other poster discribes. I have tried attachng a signal amplifier, and no luck. Could it possibly be the refresh rate that the video on the computer is set at? If any one has any suggestions I would greatly appreciate it.

I would really like to have two displays going so both the singer and the audience can see the words. This problem doesn't stop me from running my show. I have split the video signal in other venues without any problems, not sure what is causing this one.

Just a big quess. The refresh rate might be different on both TV's and your computer can set only one. Try using the wall mounted TV alone and see what happens, or if you need to set the refresh rate or not. then try the other TV doing the same test. If you can get them both to work seperately with the same refresh rate, it might mean that the splitter is bad, or too much of a difference in screen size.

Actually, I did try to isolate the errant TV, and the screen is wavey by itself. Furthermore, when using the splitter and have both tv's connected at the same time, the problem tv make the good tv have problems too, though to a lesser degree. Since the Sony Viao exports it's video/sound on one composite plug, I even tried using a external USB sound card to separate the signals. It made a marginal difference, but the screen was still unusable on the problem TV.

did a show last tues. hooked it up to the wall mount tv which is connected to another plasma tv and it did the same thing, graphics are still wavy.. i found the link mindostrike sent and hopefully this device will work,its called video card to s. video and tv adapter..by looking at this piture it looks like a vga cable to s/rca video....have to try something before spending more money buying a new laptop

[jdavia]

Only one more suggestion. You might have to use a FM modulator between the antenna and TV connections. This usually comes into play automatically when a signal becomes present. It's a Rario Shack item
Have you tried that?

Hi All
I had this same problem last week my Flipoke and Bobcox sent me some good solutions to the problem. I am now using a S video cable from my Sony laptops docking station to a Radio shack amplified splitter. This runs about $45.00. It worked flawlessly and got rid of the signal degradation. Did a 4 hr show last night and had none of the wavvy lines etc which happened when trying to hook up more than one tv as singer screen. It will also allow me to hook up to 4 tv's without a loss of signal.
Thanks to Bob and Flip for helping me make my shows the best they can be.

Thanks for the suggestion, but I already had a radio shack amplified splitter in my bag of tricks, and it had no effect on the plasma set it my situation. Thanks anyway.

[jdavia]

Here is another gadget to consider. I have one but don't need to use it at present. Go here for details. http://www.aitech.com/mx-details.htm

They say it works on any TV. So if it don't work for you, you might be able to get your money back.

[mikedomi]

We have been using and selling this since hoster has been out for sale this thing works great gives you the use of a sec lcd or crt and at the same time you can use your tv or hoock up too the bar tv's

there are users in this forum who i told about this a year ago and they just love it money well spent !!!

sparks this is more then an amplified unit.

[S. Parks]

Thanks Mike, I think I'll invest in one and give it a try, since I've tried every other option. I tried the RF converter thing saturday night, and had measurable improvement, but the sreen was still wobbly. Usable, but wobbly, at least it was better than not having a second TV.

i just ordered a maxview computer to tv ( vga to tv ) video scan converter from AITECH hope this product works..or i'll end up buying a new laptop

[S. Parks]

billyo,
Unless you have problems on ever TV you try, I'm not sure if I'd buy another laptop. I've used my system in several locations with great success, it's just a particular plasma screen in a certain bar that gives me fits. Maybe you've tried other tv's already, just thought I'd mention that.

[billyo]

S.PARK..
i've tried in on a 19 in. tv and on my 54 in. tv at home and graphics are still wavy..i'll see what happen as soon as the product i ordered from aitech arrives..maybe this will save me some money from buying another laptop..thanks
