This is pragmatic follow-up part B for episode to the boundary problem I'm Ben Alexander Emma co-host is Judge Eddie getting stuck right in our talking about episode two IDR made an offhand comment I think unfortunately about modest sizes and are comparable to Flaxman actually from our couple different tasks sources and is the suggestion being what I said said that you don't and who needs more than a 24 inch monitor are certainly a lot of people out there that say that they do so I just want to quickly address that obviously when I swim ours to a matter from point of view of Barb of energy consumption the larger the screen the bigger backlight even if it's side little LED year you've got a larger areas, require more light so inevitably it's gonna consume more more power I've also found in my investigation that when I was looking for a new monitor that the old the larger monitors are still predominate using older technology so the the cheaper to manufacture technology which is less energy efficient so the most energy-efficient mind I found was a yard was a 24 inch monitor and a sign up getting so yes one of the things I want to have a quick look at was the sizes of monitors not surprisingly is increasing so that Scott was An obvious statement I realise that people are wanting bigger and bigger screens and honestly for the desktops you I guess if you walk around with a knife only handling iPad and their much smaller screen sizes when you allow the desktop you want a bigger screen you can get away with and is fine that's fair enough and there was an IDC report showing that 31 inch plus monitors so I am sorry 31 engine up monitors that are actually the fastest growing modest size in terms of sales also doesn't mean that the technically the most popular like an absolute sense though not necessary© hour but the growing the farces because the overall trend in our PCs is a cause of Reading is trending downwards yes people getting laptops and iPads and iPhones and so-and-so for chrome books even so why am I guess our little English and I serve this only IDC data it's it's worth a look if you're curious are that your monthly report on it but some in the ends the argument about what size model you need is obviously comes down to personal preference and you can say well the majority of people can get away with a 19 inch Forester three monitor and frankly you you go back five years when 20 French miners were hideously expensive and durably argue that maybe have to go further back many separate years but you it's like everyone has to start out with computers that had 13 inch CRT screen snow that worked okay so it is sort of hard for me to say say I okay you don't really need it you really need until you've got something bigger and better and then suddenly neither something is bigger and better's I do I accept that but when I was making a reference I was really making a reference with respect to energy saving and it's inevitable of course that they will make strides in that area as well and the larger monitors will come down on power consumption but no matter how you slice it smaller screens will always consume less power than bigger screens that's just a law of physics you never gonna get around it whether that difference is significant are in the future remains to be seen so maybe there will come a point when the difference between the power consumption of a 24 inch and 27 inch monitor made through identical processes is less than 1% or something which one untimely is a fine gateways as minor as matter is fine I guess what I was really trying to get at is people think I need a bigger screen because of XYZ and they don't think about them our powder consumes and I just think that is something that people should really be considering quite seriously in our power monitor consumes that if this thing is on all day you be surprised actually how much is monitors can contain mild tomorrow as I think a settlement on in episode two EA was drawing you 35 to 40 W of of continuous power that was a 27 inch IOC monitor was my new Samsung monitor 24 inch monitor only draws 10 W so it's approximately 1/4 of the power consumption for almost but not quite almost the same size screen is a huge difference so and I and I didn't really need a bigger screen so I downsized and I guess that that's really where I was going within the first place so hopefully that addresses at that problem you I was just trying to find it here arm see what the B paragraph was on the old on the 21 inch Sony trend entrance that are used to have I wrote a dozen of them in the office and I think adding about that up on the show eventually we just realise on these issues were spending so much money on electricity running this thing is not 12 hours a day and arm yet to see a story rate of it as it is essentially that you're putting to those things in primary graphic designer and a sharp arm really quickly made more sense to jump over to even early flat panels and are you it's just the same story all the thing I find interesting with monitors and their size and power consumption is a I like it a little bit too are in the 60s and 70s with all the muscle cars and that the big engines and yard of the big heavy and I have SI a lot of power and then when there is a fuel shortage during the past 70s mid 70s and was and then they started have cut need cars or something more fuel economical so you it's kind of a similar thing with electricity and the probable electricity is it's only recently started to hit reach a point where people are realising the HDS keeps going up and up and up in price so inevitably we start looking for energy so it has the resources not in excellent infinite resources not free so game ants people should be thinking about how much I just either using because it does hit your hip pocket it does cost you money and you honestly inevitably billions of affecting the environment shook needlessly consuming four times of energy just because you're slightly larger monitor the really need to be doing that great so anyway okay so is all thoughtful episodes are to arm episodes sorry yes hundred 50 wattage hundred 51 cedar 10 Trinitron great Abbott was the CRT so the inch when I was about 20 attendees of big minders there is there is a sharper than Cleveland that would arm refurbished down they get from from companies and so on back to you cheap so we'll just be by the other in that in that respect needed economics worked out that at the time it was like the biggest latest densa screen you could get your friend a sort of affordability and down that you remember rightly the Trinitron salons of the extra flat screen whether you it was like you was really nice to in my gut big enough you would have liked more monitor to pixels across the molecular all eyeshadow mouse being but I'll you other now yells that it was the best I can screen you get there is is another rabbit was really nice and they are not having the vicarage list visibly arm is good now where I stayed CRT is our Heli the cheaper ones I typically was working on at that curvature of the sizes really really annoying and jaded help in the pincushion adjustment rate all-out and terrible are in is a degassing that you had to do every now and then to eye out the ones were you when the cell phone rang and arm you could see a lot of flickers on the screen that's right failure and you could just put else because that's an estimate had to be fully shielded speakers make the allies the speakers of the couple noise of the magnetic field it weighed £65, they were so heavily were actually heavier than the macro notice to flatten the screen on the front they had to thicken the glass significantly here because of the flat it went the more pressure because because inside the CRT was a vacuum radio you if you strengthen the glass of the front to back it was going to the tube collapse in on itself and cycles that may be things so heavy especially at the front and are you another nightmare I'm so glad CRT is going on as funnies discusses there were 43 and thinking about it that that you not 21 inch screen really was was lunch we are happy with this you think it was like I have the 17 inch MacBook Pro primary rate I can't the screen really wasn't that much bigger it was that and that's the thing with the 2427 bank rate and in our a lot of times you the way arise working are we really only have very good resolution of a very small area of looking out at a time and are we heading we have borrowed that we are kind of flicker arm were as your winterise move when you look to look at one thing you another thing it's off to another angle your brain just kind of blank cell a bit of time and then rewrites it back end sell those kinds of strange things that happen when you a lot when you're presented with cut with too much information at a time and exactly why a a arm one of the reasons why get rid of the psychomotor and just and down just just the laptop screen now that a lot of that steep shifting and you often a program of mutterings only that Ray really really have to be accessing a lot of information back and forth very quickly ageist at a think it's better to have the focus than to have the B that was it would then have the that that Brightview but yet I find year you are why finalise shifting between because I was his external monitor but why find is that you use external monitor I don't actually switch between the two are like I use the small laptop screen as my site my parking screen suffer got when I want as I drag I would shove it in there and the winners are working on I tend to focus on those in the larger monitor brand I find that I hate looking at the laptop screen was next to the big monitor because the size of the pixels in the is is more dense on the laptop screen so you I find myself refocusing despite the fact that they're both exactly that at approximately same heights of the laptop stand and site work I do anyway and despite the fact that it's exactly the same document there are different totally different sizes of the two screens because the pixel density and yard promise of refocusing on it gets really irritating solace and I'm not looking at the laptop screen memos will be shut here that no and that's for the longest time I was always begun to get dumped all displays and delivers the cheapest way to get that real estate by now now I'd say that you a few men a few for doing what he really really big screen Anita really that really big screen that just a really really big screen trailer car jumbo budget things together Elisa Lee's night if you want to notarise more than a few years because that is just the it's pretty RBS eight on the need any science to me that that jumping back and forth between two things are slightly different is our is about idea to do for�
