Hey, here is my problem hopefully someone can help.

When i try to watch YOUTUBE or other online streaming video's on my wide screen monitor, i can't make them go to full screen, when i try it splits my monitor into 2 different colored triangles, black on top white on the BOTTOM, does anyone know how to play full screen youtube videos or other videos like that on a wide screen monitor?

The monitor is a Dell, I'm USING Firefox with Windows Vista Home Premium. if any other info is needed let me know.

Thanks in advance for any help, it will be much appreciated.


What do you mean by triangles?it LOOKS like this

Wow! Never seen anything like this. Does video play OK in normal screen size?yeah, it plays fine if i just leave it as small screen, but when i try to go to fullscreen it does that. the AUDIO still plays but the video turns into triangles, also video's go on full screen fine on my non-widescreen monitor, so I'm really stumped as to what the problem is.Two things to try: reinstall Adobe Flash, reinstall video drivers.Broni, your the Best! thank-you very much for your helpful advice, all works well now, not sure which one of the 2 it was but after i did both it now works great. Thank-you!Great news!!
If you want me to bet $5, I'd put it on Adobe Flash reinstall. Since they took over Flash Player from Macromedia, nothing, but trouble.
