Choppy Video on second monitor

[decompyler]

Hi there,
Thanks in advance for any advice.

I have my 2nd display on my vid card hooked up to my tv via DVI. If I run in full screen on my main, there is no problem... If I run in full on my second, chop suey time. Curious thing is... if I just maximize the window instead, it looks like a fairly normal frame rate. Let me know if you need more info about this.

Thanks!

Same issue with dual monitors here.

VLC is fine on the primary monitor but if I drag the VLC window to secondary monitor and make it full screen the video is choppy, It doesnt matter if its a low res xvid or HD .mkv etc. (CPU usage is very low regardless during the choppiness so I doubt its that).

Just to troubleshoot I tried playing a file in windows media player and it does not experience choppiness on the 2nd monitor.

Both monitors are hooked up via DVI.

i7 920 @ 3.6ghz / EVGA GTX 480 1.5GB video card / X-Fi audio / Win 7 64bit

Any ideas appreciated!

I've been reading up on this, so I thought I'd pitch in. I've had no problems whatsoever using Boxee/VLC on my external display until last night. I have a C2D 2.0 GHz, 4GB (3.3 usable) Black Macbook. I was running it off of a 500GB 7200rpm Hitachi drive. Yesterday, I installed a 64GB Kingston SSD in the optical drive's (now retired) spot.

I booted from SSD and fired up a 720p episode of Lost on the external display (mini DVI -> DVI). It was choppy. I attributed it to the SSD but had no clue why a SSD would have worse performance than a HDD. After a bit of research, I found an answer online that might solve this mystery. Someone suggested that the 64-bit version of VLC has choppy video on external displays, and that if you install the 32-bit version, you'll be good to go. I'm going to try this as soon as I get home this evening, and I'll report back then.

It's been so long since I installed VLC on my HDD, that I'm pretty sure it was the 32-bit version. I hope it works!

There isn't 64 bit VLC for Windows yet (well not stable release). And issue has something to do with video output, and it should bother all VLC versions.
