Viewsonic VP930 or ACER AL1922AS

[cjmart1]

Hello, I need a piece of advise.

I want to purchase a LCD panel and I have two candidates, VP930 or AL1922AS. Both have the same specs (19", 1000:1 / 250, 8ms GTG, VA panels, one MVA, the other PVA, 1280x1024@75 Hz native resolution, DVI input, etc.)

I have seen some lines about the VSonic here at Tom's, but not a line about Acer. There's a difference of 200 € between the two and I have to meditate it.

I want it for general purpose, photo editing, video editing and occasionally a 1st person shooter. I have discard TN panels, because of color treatment.

Can anybody give me a hand? 🙂

Many thanks

C.J.

My best advice in this situation would be to actually look at the displays on these two monitors, then judge for yourself which one has the better picture. If you think the Viewsonic does, you have to decide if it's superior enough to warrant the extra money. If you think the Acer has the better picture, your choice is easy. No one can tell you which one looks better to you. Not everyone sees things the same way.

thank you for your answer.

The point is I have not much information about the Acer panel, owners experiences, or good tests.

Let's forget the prices. Which one would be the one? The best? Or both are pretty equals? It wouldn't surprise me, because of the specs.

Thank you all

I don't have personal experience with either of these particular models. From what I've seen on the net, most people seem quite satisfied with both of them. I have had to deal with both companies regarding returns, and both were responsive and gave me, or my customer, no headaches. That said, perhaps your best bet would be for someone who actually has one of these to weigh in.

Hi,

Just wanted to point out that the AL1922AS uses the same panel (Samsung LTM190E4) as Fujitsu-Siemens P19-2 and Samsung 193P+. From what I read, VP930 is supposed to have superior overall response time than these two.

For instance:

http://www.xbitlabs.com/articles/other/display/response-compensation_10.html

Considering that AL1922AS is advertised as an office display, its doubtful it has any better response time curve.

these links have been very useful. They contain a couple of very good 19" panels tests.
They have light my way and I am nearly convinced of purchasing Samsung SM970P. It's the best in specs and test behaviour among VA panels.
I still don't want TN panels and after reading the 970P test I am thinking nobody needs them...speaking of multipurpose panels

By the way. We speak all the way about black to white or grey to gray speed, ghosting artifacts etc. All right. All this is because a TFT cell have to react to voltage and to show light (on) or not (off) and all the mid states (greys). That is from 0 to 255 (scaling black to white). And we all compare to (and remember) CRT tubes.

BUT I also remember the mechanism of painting a scene on to a CRT screen. An electron collides to the screen and excites a special compound that emits a visible radiation (we see some colour or white light) and later stops emitting to pass to an inactive state (we see that point in black).

NOT all the CRT screens have the same behaviour in emitting or stopping when the electron collides or there is no electron. NOT all the sensible compounds are fast enough to pass from excited phase to inactive state. That takes some time, some miliseconds. Does this sound familiar?

We are living the same story, but below 20 ms I think TFT panels mostly give us a very good image, despite the specs and speeds. CRT also shows some ghosting or flickering, but most of us had a 150 bucks CRT monitor in stead of an EIZO and I heard no complaints...
How many of us have applied a colorimeter or a colour pattern to our venerables CRT monitors? And now we eat all the marketing crap about delta E and all about TFT panels.

I have seen those tests at behardware.com and they have made captures with a Canon EOS 350D at 1/1000 seconds. Some ghosting were seen with the CRT they took to compare to. But it's normal, no human eye can afford to see what the Canon sees at 1/1000 secs. And if you see carefully the tests, the CRT captures, you'll see them bright and poor contrasted. You would reject any TFT showing those captures!!! Despite the excellent speed performance.

But here we are, devouring tons of tests and reports, watching the ultimate specs and carefully seeing some captures at 1 milisecond. Marketing departments kingdom. They are selling milisec. and we are buying them.

The age of slow TFT have past. The cheapest one offers speeds of 20 ms and below. Now the important is the colour they offer, because we all want to see our pictures as they were taken. And Marketing actions goes to speed...ISO speed, GTG speed...Stinks!! They say "you want speed? Alright, here you have" and they give us a panel very fast but with poor colour pattern. Because they think speed is what we need. ANd they don't have better or newer panels!! They retouch what they had to improve speed, at the expense of image quality. And moreover, they manipulate the speed, saying the GTG one (always lower).

Funny, there's a couple or three manufacturers and we should decide either if we like colour treatment of korean, speed of taiwanese (TN AU-Optronic panels) or we should bury ISP panels...

Excuse my speech. I suppose I was bored.

Best regards to every one!!!
