LED display shines through

PLS and IPS are almost same… SAMSUNG call their IPS as PLS rather than LG call theirs IPS. Due to patent, SAMSUNG cannot use the word IPS. both two are slightly different but almost same.

If you want to get more high contrast ratio, consider VA panel. There be various - MVA, PVA/S-PVA, A-MVA/A-MVA+ but almost same too. (AH-VA is some kind of IPS. Don’t be confused.)
- The cons of VA panel - late response speed. afterimage would happen. So it rarely be adopted as screen of notebook.(and duralibility issue)
Anyway, usually we don’t use MM as movie player, so it might not be the issue. - The pros of VA panel - Cheap, low light leak, darker black, higher contrast (than IPS)
- contrast ratio of VA is usually 1:3000 ~ 1:5000 while IPS usually be 1:1000.
- The cons of VA panel - late response speed. afterimage would happen. So it rarely be adopted as screen of notebook.(and duralibility issue)
-
There is another option TN panel. High latency is good point but somehow useless for MM. color is not correct by angle.
But remember; the higher(expensive) of type A is better than the lower(cheap) of type B always.

@Sean said in LED display shines through:
VA
sorry for misunderstanding.
I kept in mind and thought about VA but typed PLS.
Of course the diff in IPS and VA is visible especially in dark color, due to the higher contrast in the last one.
You are right.
Late response speed is not an issues for MM projects I think. -
@Sean Thank you very much for that info. I need a monitor between 17 to 19 inches. I’ll see if I can find something.
-
@Sean Can you please tell me if this monitor is going to work for me? Please look at the specs. Thank you.

@maiky09 it is not VA. Check all monitors suitable for you in terms of size/price and check at other website which type of matrix these LCD have. As was said above, the best option is VA (Vertical Alignment)

Look in the show your mirror, must say I’ve not had that problem with mine, SamsungTV with a RPI https://forum.magicmirror.builders/category/12/show-your-mirror

I decided to buy the one in the following link:

I know it’s not VA, but I saw a tutorial recommending it, and the work went well. I hope it works for me.

@maiky09
Finally, it depends on your environment where MM is used. So IPS (easy to get) could be enough Or even VA couldn’t. With low transparency of spymirror, 1:5000 contrast might not be satisfied at all on strong daylight condition.
The only point I want to tell is to consider FHD (1920*1080). It is the max resolution which RPI can handle (but if you consider other SBC like ATB, RockPi, Odroid, Nvidia Jetson, … etc. 4K could be available). You may probably need more real-estate to show other cool info. -
@Sean Again, thank you very much for everything. Excellent information.
