LED TV in a below freezing shop ?

[krisinwast]

I heat my shop with a wood stove , winter temps. can easily drop down to
the teens , I want to mount a TV on the wall to use as a monitor for a PC
looking for suggestions of one that can survive the cold without damage
the temps in the summer get over 100 (Fahrenheit ) as well

I run both a full blown tower PC and a TV in my garage that gets well below -20 freedom units.
Your TV will have a little ghosting and the image may be dim for a while before it warms up but don't worry too much about it.
I assume the lifespan will be shortened but I have no problems with that considering it's a garage tv.

Been considering a smaller one from wally world at about the
100 dollar range, maybe a LED as opposed to a LCD ?

My monitor is LCD and TV is LED, LCD take a little longer to warm up I guess. That might be due to age/technology as well however. Otherwise no difference.

So I read a little bit about it on the web , apparently LCD is older tech.
and LED is a LCD with LED for lighting the background , seems to be
controversy about LCD being a liquid that will freeze or not , apperently
it doesn't freeze , but kinda "jells " till it warms up , also read were LCD
is not a liquid at all , Guess I'll give it a shot and hope for the best .

Several different families of liquid crystals are used in liquid crystals. The molecules used have to be anisotropic, and to exhibit mutual attraction. Polarizable rod-shaped molecules (biphenyls, terphenyls, etc.) are common. A common form is a pair of aromatic benzene rings, with a nonpolar moiety (pentyl, heptyl, octyl, or alkyl oxy group) on one end and polar (nitrile, halogen) on the other. Sometimes the benzene rings are separated with an acetylene group, ethylene, CH=N, CH=NO, N=N, N=NO, or ester group. In practice, eutectic mixtures of several chemicals are used, to achieve wider temperature operating range (-10..+60 °C for low-end and -20..+100 °C for high-performance displays).

Hope this helps

I have had an LCD TV in my unheated detached garage for about 6 years now. It has no issues in the cold.

The liquid in LCD will NOT freeze in the cold, but it does thicken, to the point that the screen response time will slow down. But unless you're playing a high framerate game, you probably won't notice. The LCD display on my car Sirius radio is a great example of this, where it can take up to a second for the screen to show a change.

The backlight in LCD is a cold cathode fluorescent tube system. These can take a little time to warm up when it's cold out, but they WILL still light below 0F (unlike many hot cathode fluorescent tubes).

LED LCD uses LED backlighting with an LCD screen. These should not have the same warmup period as a cheaper LCD in the cold, but would otherwise be the same.

OLED (the newest technology) uses neither liquid crystals, nor backlights, and for this reason, I would expect an OLED screen to be just fine, even in extreme cold.

I've had an LED TV in my detached garage for a year and a half now. No issues whatsoever.

Thanks guys , nice to have some feedback and information about real
world experience , looked up C to F temps , -10 C = + 14 F and +60 C=
+140 F so no worries there , if the temp drops below +15 just put the
TV in the house . to cold to work out there anyway .

My LCD tv and old laptop have been fine in the cold garage. If it's extremely cold out I'll wait until the wood stove warms it up a bit before I turn them on.

Seura or sunbrite.

Seura or sunbrite.

You mean Sharp (Hisense) and Sony right? Same guts with tweaked settings, fancy frame, and a price point.

It is a bit like outdoor painting.
"If it is too hot/cold for me, it is too hot/cold for the paint/TV"

Just use a fan to move the hot air around the shop.

The biggest problem is not the LCD/LED. It's the capacitors they used in the electronics. I have had PC motherboard that blows out with a big bang from being in the cold.... same with the B&D inverter type charger / starter, huge huge loud pop. Unless it is specific grade caps used.... most consumer grade electronics especially electrolytic capacitors have a very good chance of blowing on start. It's different when you warm up the TV turned it on and left it outside running in the cold than left it in a cold shop and turn it on initally to start it up.

Most electronics work better when they run cool. That's why they have big heat sinks in them to dissapate the heat. I think you will be fine.

I have a 46" LED in my outdoor bar year round as well as a desktop computer. My friend/TV repairman told me it wouldn't last a year, that was 7 years ago, so this year I went to a 50" and brought the 46" indoors to give it a break.

Plus an internal heater and fans for active heating and cooling depending on outside ambient temp and humidity.

Mine is going on 8 years being outside (and fully exposed to the elements) through all 4 Ontario seasons. I've watched it from the hot tub while the tv had ice and snow built up on it.

I've also watched it during heavy rains
