Interactive screens with condensation?

[Zourous]

We have one screen that gets this for sure. It's in the dance studio that has 3 walls that are outside walls so I guess the studio gets extremely cold in the winter months and when the screen is in standby I'm guessing it is generating a small bit of heat that is causing condensation.

 

I've got other screens in another building that I presume is getting cold. I don't get visual condensation but I've had untold intermittent problems with video output on vga and hdmi cables on different screens.

 

I've think i've resolved the studio screen problem by putting a thermostat plug that will kill the power to the screen when the temperature drops too low, but only time will tell.

 

So there must be others out there that have experienced the same thing??? Please share your thoughts.

When I read the title and first two lines that appear in the app, I was going to suggest trying leaving it in standby mode to try and keep it a bit warm. Condensation forms on cold surfaces - hence demisters in cars being electric heating elements on the windows. As you say, you'll get more of a problem in rooms which are cold - the other influence is the level of humidity. I'd expect your dance studio to have higher humidity than the average classroom. Sweaty bodies....

 

Suggestions: get a bit of airflow in the room - everyone will benefit from that! And try and keep it a little warmer - preferably the room, but if not, maybe leave something like a greenhouse heater near the screen. I have one in my piano* as it was suffering from damp in a cold room. You could also try a dehumidifier - might be worth it in a dance studio.

*Well it's technically a much more expensive piano heater, but pretty much the same thing.

My thinking is that the condensation is forming over night during the winter months. I don't think I can leave a heater plugged in, and it would just get meddled with anyway or even taken away. I don't see it being any cleaning materials on the screen, this wouldn't affect the internal video ports. I think the thermo plugs may be the best and easiest thing if this is what is happening.

Interactive screens are a breeding ground for bacteria, with this is mind I have noticed these screens get cleaned a hell of a lot by well meaning people. While this is a welcome task, the cleaning I have seen ranges from a complete drenching with a sponge to a wipeover with an antiseptic wipe. Maybe the problem is more it has more exposure to moisture and this could be tackled with a cleaning policy and some staff training ?

 

Had this issue on one of our screens, and while noone owned up to the drenching it has now stopped with a simple 'clean only with these wipes' policy.

 

I've seen it on occasion with various brands of screen due to cold weather. It should clear after a few hours of use. We normally see a spike in reported cases after holiday periods or if the weather suddenly dips.

 

The grubby finger issue is something we are looking at. We've spent a lot of time looking at eye-health; low blue light (like the night-shift mode apple have just added) , flicker free displays etc but up till now we've not put much thought into bacteria on the screens.

With regards to condensation in the screens - this is normally an issue that arises when the screen is being assembled. Due temperature changes this can take a while to 'go away' so to speak. Our screens are now vacuum sealed at the factory to ensure that this is not an issue.
