I am trying to understand what "version" numbers I should be on the hunt for on the outside of the box to get the best possible chance of picking the best panel. I still don't have all the pieces together though. Here is what I have so far:
Construction Version Manufacturer Desirable?
S-MVA CH01 ChiMei Maybe
? TS01 Samsung Yes
? HS03 Sharp No?
? TH02 Maybe
As you can see there are still a lot of holes in this matrix. At the least I'd like to understand which ones to stay away from. Any help would be appreciated. Thanks.
Here is what I've found out:
IPS panels are popular for monitors where accuracy is important for things like photo editing. Samsung doesn't
use IPS panels, but Panasonic and LG do. Samsung uses VA types
, along with Sony and Toshiba. In order of contrast ratios for VA panels (lower number being better) it goes:
2. UV2A (U-MVA) (?)
For the EH line, the panels used are various VA based panels, including S-PVA (Samsung), S-MVA (Chei Mei), A-MVA (AUO Optronics), and a Sharp made panel that I'm not sure what the matrice is
I know the 37 inch EH uses only AUO or Chei Mei panels as Samsung and Sony's joint S-PVA panel supplier, S-LCD, doesn't manufacture panels in that size. Same for the 39 inch UN39EH5003. It also seems like the 50" and 60" sets don't use S-PVA panels.
So currently I wouldn't expect to find S-PVA panels in 37", 39", 50", and 60" screen sizes.
If you can find a "Version" number that can help. It's usually a four digit code, on a sticker on the side of the TV.
Anything starting with Cxxx or Bxxx is Chei Mei. Hxxx is a Sharp panel. Version "A" panels, are made by AUO, and have the labels ACxx, AAxx, and BAxx. I also think Mxxx is an MVA from AUO Optronics. The service menu for Mxxx shows "L."
Samsung currently seems to be using Txxx to label their own S-PVA panels. TS0x and TH0x have both been tested via the service menu and indicate Samsung panels.
>>>> So going off of labels Cxxx/Bxxx = Chei Mei, Axxx/BAxx/Mxxx = AUO Optronics, Hxxx = Sharp, and Txxx = Samsung S-LCD
Samsung S-PVA (Txxx) are generally the preferred panels to get (best performing in terms of Contrast, black levels, viewing angles,etc). The other panels can have less desirable traits, such as off-axis glow to the blacks for S-MVA, purple ghosting on Sharp panels, etc. (At least that's what others have complained about).In general, most people seem to prefer S-PVA panels, but that doesn't mean the other panels are necessarily bad.

Some people on the forum have gotten carried away and let themselves develop an automatic prejudice about certain panels and a bias towards others. This is clearly evidenced by the number of people casually referring to some panels as "the bad panels", "the garbage panels", etc.
If you want to get your hands on a certain LCD panel, that's fine, but please try to stop badmouthing the other panels and vendors so much. It only perpetuates spreading more preconceived biases in people, and isn't really helpful. New people come to thread now and immediately start posting by aksing whether they got one of the garbage panels to see if they need to return it. They may not even have any problems with the picture, but they've got it embedded in their head that they might have a "bad" panel on their hands that they need to get replaced. I think they start to believe that certain panels are inherently faulty or defective.
If you get a certain panel it doesn't mean the panel is "junk/garbage", "defective", or "bad" and needs to be replaced/returned. It just means it got a panel with a certain LCD tech in it.
It's not like Chi Mei and AU Optronics just pump out bad panels from some shady factory. These are BIG companies and are some of the largest LCD producers worldwide.
There is no perfect panel, and LCDs all have their pros and cons. The reason people like the S-PVAs on these current Samsungs is because, at the moment, they have a slight advantage in a few areas of picture quality which are weighted more importantly (such as contrast and viewing angles) over other panel techs. That could change though in the future, and the other companies could leapfrog them and come out with a better performing panel.
Probably the best way to find out the panel is to get into the TV's service menu.[ Note: Entering the service menu will reset the TV settings to factory default !! ]
To enter the service menu:
(TV in Standby Mode)Mute
(in rapid succession).(Non-US versions, Press info-menu-mute-power)
Look under "Option" or "Type".
Search for your model's "inch number", and look at the letter immediately following
the "inch number"
R:AUO (au optronics)
So a UN40EH5000 with a samsung panel, would like this: 40A
Exit with power off on remote.1) Some reading on Service Menu information...2)...and a bit more here
Here are some pics of Samsung labels, and the service menu:Edited by chicolom - 3/12/13 at 7:56am
