Which screen for Magic mirror??

PhilReis

Hello,

I need a new display for my Magic Mirror.
But which display is the best?
VA, IPS or TN?

i have read that IPS have the best black level but the highest power consumption.
TN have the lowest power consumption but not a good black level.

OLED is too expensive at the moment. (I found only one for 5000€, from DELL)
My budget is between 100-200 €.

Thank to all,

Phil Reis

20" between 24".
I think it will be a hole monitor. But first i want to know which display type is the best.
My old display have a bad black level, so it´s dark in my room you can see the backlight very strong.

Oled
Ips
Tn

So, IPS panel is currently the best option, high contrast ratio is also something to look at.

But, in dark you will always see the backlight,
regardless of ips or tn. (this is why many people builds the mirror exactly as large as the screen itself so there is no/minimal “light” edges on the mirror surface)

I’m curious why you left VA off your list?

VA Panels have by far the best contrast ratio and the deepest blacks. I understand they have color shift issues, but it seems like the deeper blacks would be more important, especially if you are planning on just displaying white text without images.

Something like this seems like a great candidate: https://www.amazon.com/23-8In-Gw2470Ml-1920X1080-Slim-Bezel/dp/B074CT3MZ9/ref=sr_1_5?s=pc&ie=UTF8&qid=1515113895&sr=1-5&keywords=benq&refinements=p_n_size_browse-bin%3A3547805011

I think VA is cheaper than IPS too, and i wouldn’t generally recommend them, but seems like the perfect use case for a mirror…

Just too add, take a look at this video from about 8 minutes to 10 minutes in. Specifically if you freeze right at 9:05 you will see how much better VA is than IPS at blacks.

Thanks for your suggestion. Looks great! I just bought an BenQ GW2470H with VA Panel for 79€ for my first project off eBay!

@nh_790 I actually missed that VA was mentioned. But yes, the VA is a good option.
And the BenQ GW series you are linking to is actually the ones I’m planning to use in my next mirror, I haven’t tried it yet so I can’t give any recommendations, but on paper it looks really good ( 3000:1 contrast where almost all other screens in that price range only has 1000:1).

I’m also looking for a new screen.
But i need a 32’', really flat and, because i’ll use a PIR to send the monitor to standby off/on, without any logo or information “Signal lost/ Signal found” or similar …

Any ideas?
Thanks

Nope, none :)

im looking for similar myself.

Instead of PIR I would suggest using one of these: https://www.amazon.com/gp/product/B06Y5G27G6/ref=ox_sc_act_title_2?smid=A243HB0NZWY05K&psc=1

looks like they can detect motion from behind the glass which PIR cant. Check out this video https://www.youtube.com/watch?v=9-q2klKJ280&feature=youtu.be

As far as the no signal message, i have monitors from asus, viewsonic, and acer, all display the message. The viewsonic and asus only for a few seconds, and the acer for a bit longer maybe 30 seconds or so…

Hey rrrene, did you get your monitor? Can you tell us how it is? are the blacks good and does it display “no signal” or similar? if it does display the message can you tell us for how long?

thats correct. But keep in mind, that microwave detectors are very sensitive. So if u have a closed room, it will be ok. If u are thinking about an installation in big open rooms, that thing can detect motion behind walls also. So it can be, that the detector detects more often then u wish ^^
Microwave detectors sending microwaves and expecting a certain reflection. Because microwaves will send with about 24 Ghz, they can travel a hugh distance.
Just to know ;)

@nh_790 Good morning! I will just get the monitor today. I‘ll test and let you know :)

@nh_790

Hey, I just got the screen. The black is very great. There seems to be no clouding as far as I could see in my conditions. Unfortunately I don‘t have my mirror yet as I just started with the project but also the text looks great on it.

Now I need to see how / if I remove the housing…

The only thing bothering me is that the no input message is coming up on a blue screen. Just for about 10 second but that‘s just not perfect…

How did you all manage to react on these messaged? Do you just black your screen or do you switch of hdmi? If yes I would love to hear your steps.

Best regards,
René

@rrrene Try changing the HDMI auto detect to on. on my benq monitor when its set to on it displays the no input on a black screen, when off its blue. it displays for 60 seconds either way. but black is better than blue…

Also you can disable the purple splash screen when the monitor is first powered on via a hidden menu. With the monitor off press menu and hold then press power. once the monitor wakes up press menu…

@nh_790

Wow!! Thank you very much for that two tricks! Working just perfectly. I think this monitor is now the perfect one for my mirror. Although this will take some time… :)
