TV LED BackLights

I am shooting a video in an office that has quite a few blueish purple LED TV backlights. Normally I would turn these off, but I'm curious if there is a trick to shoot around these with out the blow out. It gives a cool mood to the office, but I don't want to ruin my shoot. Here is a test photo on an iPhone.

That is what I despise about using LED instruments for color.

If you looked at that on a vectorscope you'd see a spike going well outside the blue area, in terms of saturated intensity.

Turn the LED backlights off - it's your best bet.

Thank you Alan for confirming this. I scoured the net for info, but majority of everything pointed to using LED Panels for general lighting or back lit TVs, not TV LED backlighting problems for video. If anyone can share any links that explain in detail why this happens, I'm all ears. Thanks again Alan.

The LEDs are emitting that pure color at very high saturation levels. So you're seeing clipping there, where the color falls off only as the light output is driven beyond the camera's ability to capture it.

Can't imagine what the point is of LED backlight on a TV monitor. I could see the monitor becoming a framed piece off art display or slide show when its not being used but shining distracting lights around it is weird.

Even if you can't find the menu to turn it off, looks like 8 small pieces of black gaff will easily solve the problem.

And so it goes.
