Do Modern Monitors Produce Less Heat These Days?

Hi Ozbargainers and Merry Xmas.

This is going to be a n00b query but I'm clueless, all the current specs and abbreviations are confusing me and can't seem to find a blanket answer so I assume there might be too many variables.

I've been trying to cool down my home study/office since it's summer and have done all i can in terms of insulating, blinds, etc. Now narrowing down to my hardware, my old PC seems to run reasonably cool, however, I put a thermometer on top of my monitor and it read 32 degrees. I know that's not an alarming figure or anything but I've been wondering if technology has advanced enough that today's equivalent would make less of a heat impact? My current monitor is a HP LP3065 (30'" QHD) which was the bee's knees back in the day but i've now had it for around 10 years or more!

I've been curious about deals for cheap monitors like the current Dell S2721DS for under $300 and wondering if it would make any difference due to slightly smaller size and newer technology? To note, I don't game or anything so don't really have many requirements apart from decent looking screen and size, and QHD.

TL;DR: Will upgrading my old monitor make my room less warm?

    Most electronics in your room will inevitably produce some sort of heat.
    The real issue is how well your room/building insulates heat.

    But to answer your question, the short answer is no. They're all the same shit with how much heat they give off, given similar specs.
    A 27inch 4k monitor in 2015 isn't going to heat up your room more than a 27inch 4k monitor in 2020.

    Based on a small amount of research I think that the Dell monitor would produce less heat than the your current HP monitor. This is based solely on the input wattage. The HP has a maximum wattage of 176 watts (source) and the Dell has a maximum wattage of 40 watts (source - I couldn't see a wattage on Dell's website). So even if the 2 monitors both have a 10% power loss to heat the Dell monitor would have less than a quarter of the energy being lost as heat, so theoretically the newer monitor should be cooler - though I would imagine a newer monitor would have less power loss due to heat. and How much that would translate to in terms of temperature, I don't know.

    Though perhaps someone who is smarter than me can weigh in.

      I'm not smarter, I'm just posting after… lol

      Hot Air Rises and a Monitor Vents mostly to the Top you will achieve the highest reading with a Thermometer
      atop the Screen.

      As long as the Monitor isn't doing crazy things and the vents are clear, I don't see a problem. I don't think a blanket is the answer…

      You can buy a Cheap Digital Thermometer to record the High/Low Room Temp…
      …or a Compact Wine/Beer fridge* and then you won't care about the Monitor anymore.

      *Fridge may produce heat.

    My room noticibly heats up when I play a game on my PC, or when I've got lots of projects open for a long time. It's handy if your room is always a little cold. If a small room has dozens of electronics plugged in and turned on then it can add up. The biggest difference more than monitors or anything else is whether my PC is under load or not.

    Out of all the electronics that can emit the most heat, a monitor is near close to the bottom of the list, and would have marginal differences between models i'd imagine

    Although not a monitor, our old TV (plasma) was a great room heater. It felt like you were walking past a fireplace when it was on. I just replaced it with an OLED and you don't feel any warmth walking past it now. AC should work better now.

    Think anything with “lights” in it will produce heat.
    Example: a 100w charger (laptop charger) vs 100w light bulb.
    The light bulb gets very hot compared to the charger.

    Also recently got a cheap USB powered LED strip. It is just one color, but after turning on within 1 minute it is very warm to touch.

    A monitor should / will not make much difference to a room temperature. It doesn't work very hard so doesn't make much heat. Your PC will make much more heat.

    I've got some cheap (old) monitors and I can't feel heat off them by hand. I also have a 49 inch 32:9 monitor, also cannot feel heat off the top by hand. If you can't notice to touch, it's not going to heat up an entire room of 20m3 based on a small room of 3m x 3m x 2.4m.

    Need to consider that 32c doesn't mean much on its own without knowing ambient temp. Was the room 30c ambient?

    TL;DR: No.
