Hi, does anybody know if the new Philips 19” TFT 190P7ES with P-MVA panel incorporates Overdrive technology ? I have seen nothing about in manufacturer specifications...
Any reference to some review on this monitor would be wellcome too…
Thank you very much.
Best regards.
There is already an old thread on that monitor.
190P7 has 8ms gray-to-gray response time and this means it adopts overdrive.
This is not properly a review but a chinese presentation.
(don't use combo-box to navigate the article or you will lose translation)
It seems to have a very good price/performance ratio.
Hi, I have two doubts about prad.de datasheet for this monitor.
1. Is color depth right ?. based on the type of panel, -a VA one-, I think it would have to be 16,7M instead of 16,2M, at least.
2. Is 100% sure that the type of panel is P-MVA ?. Although "official" specifications seems to fit with P-MVA panel ones, in some forums(from Italy) are posts commenting some doubts about (P-MVA or PVA)
Thanks. 
it seems to be a very nice TFT monitor with good performance, and the constrast ratio 1300:1 is an incredible value for us 
So gutaber mit dithering ?
Warum ? Panel von AUO hat 16.77 Mio
???

I think the english translation is:
"What the f**k! they write 16,7M colors and use dithering!?"
The answer is... YES!
Samsung LTM190E4 officially have 16,7M colors...
In some review I've read that the rival Premium-MVA panel by AUO use temporal dithering.
Maybe this is not correct but I don't have any difficulty to believe it.
I think a very good question is:
"Which is the better approach: temporal or spatial dithering?"
Using some logic, I believe that spatial dithering has more limitations.
Aber Viewsonic VX2025WM habe auch MVA von AUO.
Und es ist 8bit
But Viewsonic VX2025WM has MVA panel by AUO too, and it is true 8bit.
Both things are not exclusive because every panel is a different story.
Samsung, for example, don't use dithering in S-PVA panels.
Sometimes is cheaper to use 6bit, electronic need not to be strong enough. 8bit is much more expensive.
There is a lack of 8bit offers 
970P is S-PVA and it is 6bit
In fact most of Samsungs are 6bit.
Sad but true
Samsung is a manufacturer of PVA and 970P carries S-PVA panel. That was a big surprise for everyone when realized it is 6bit panel.
To proove that see Samsung's specification:
Difference between MVA and PVA is minimal and the main point is which electronic is used to drive that panel. That's why PVA/MVA panel should be in fact 6bit.
You can achieve faster response if you use 6bit instead of 8bit. Difference in angles is very little, I had VP930 (P-MVA) and S1910 (S-PVA) on my desk and I realized that angles were really good for each of them. Also I had a chance to see VX2025WM (P-MVA) and its angles were pretty good.
When you check this:
You will clearly see there isn't any MVA panel with 16.2 specification matching 970P specification. As a Samsung's flag-ship of lowend it is carried with PVA LTM190E4 (971P) and by its precedessor (970P).
Colour depth noted for panels is tha maximum colour depth that can be achieved by appropriate electronic. Dithering is not a feature of panel but electronic.
Your are right about dithering, but Super-PVA is a whole different matter.
The S-PVA panels have an eight domain pixel structure versus the four domain of the classical PVA.
This article can be useful:
Your Samsung's specification prove that 970P is a simple "a-si TFT/PVA".
a-si = "amorphous silicon" not "a super incredible" PVA.
I don't want to say that S-PVA can't have dithering because its nature...
I said that "usually" Samsung don't use dithering with S-PVA panels.
However maybe we are saying the same things.
My english skill is not very good.
Nobody knows exact difference between P-MVA and S-PVA
Many think these technologies are in fact same. You know that PVA is a copy of MVA. Unfortunately Samsung usually uses dithering, sad I know. It is up to manufacturer how he uses panel. It is more cheaper
MVA and PVA can produce 8bit by their native. I read here somebody wrote "S-PVA uses spatial dithering and P-MVA uses temporal dithering". But that's not true at all. It is mixing up two facts - panel that can produce 8bit colours and electronic. Dithering and FRC is not a feature of panel at all. Strongly detach these two things.
You cannot say "it's MVA it is 6bit" or "it is MVA it uses dithering". Let me say little examples:
VX2025WM = P-MVA 8bit
VP2030 = P-MVA 8bit
P19-2 = S-PVA 8bit
970P = S-PVA 6bit
VP930 = P-MVA 6bit
In one time only you can be trully sure - models equiped with TN are always 6bit. Also in retrieving facts about 6b or 8b in case of VA panels some people usually mistake colour banding (nice example is Dell 2407 with banding issue, fixed in A02 revision, caused people to think it's 6b).
I want 19" 8bit without silver bezel, is that too much I want ?
Nono, your english is good enough and I think you're right we are talking about same thing - we cannot trust manufacturer's specification
Sorry but I think you are making a bit of confusion... 
P-MVA and S-PVA are not equivalent technologies.
Premium-MVA (P-MVA) has a four domain pixel structure like "plain" PVA (not Super).
Super-PVA (S-PVA) has an eight domain pixel structure and the correspondent MVA version is the very recent Advanced-MVA (AMVA).
Read the AU Optronics news:
You are right... Fujitsu-Siemens says the P19-2 has S-PVA panel.
But this is simply unbelievable considering that the smaller S-PVA panel under production is 20 inch size.
I don't see anywhere a different 19 inch PVA panel rather than LTM190E4.
If you want a 19'' panel good for graphic work I think a LG.Philips S-IPS is a better choice:
BenQ FP91R
Nec LCD1990FX
Nec LCD1990SXi
LaCie 319
...or the expensive SA-TFT Nec panel:
Eizo L797
Eizo CG19
There is not detailed specification about S-PVA nad P-MVA. Nobody knows exact implementation. The only one thing known is basic principle of (M/P)VA panels.
Fujitsu created MVA, as soon as they put it onto market, Samsung came with a copy - PVA Since these times all is top secret
Maybe there are not enough public informations to build your own MVA/PVA panel, but you can found a little something on the web.
There is a way to know if PVA implementation is similar to MVA.
In this case Samsung must pay patent license to Fujitsu.
Big firms takes every excuse to unleash their lawyers.
They do not
I ordered it today. Tomorrow it will came
We will definitely see
