HEL80 Monitor Question

Heya - I'm looking into buying an HEL80 (or possibly an S96J) real soon and I had a few questions about the LCD that the HEL80 comes with.

What's the response time on the WXGA (glossy) and the WSXGA+ (matte) LCDs you can get on them? Is it fast enough that there won't be ghosting or anything, or is that a problem? Also, which one is more recommended? I'm going to be playing games (though not much like FEAR or Quake 4) and I'm going to have 2gb of RAM, so which one do you think will end up looking better?

Okay, that's it. Thanks!

 

Well i have the glossy screen and i was playing half life 2 before and it looked beautiful but yeah the matte is meant to be a better quality screen but not by much

 

See your answer in the ASUS forum where you posted this same question.

 

Donald Stratton or anyone else,
I was wondering about the specifications for the various lcd's offered with the Compal Hel80 - can anyone supply a link or info? One thing I'm specifically interested in are the H/V viewing angles for the WSXGA+.

Also I've noticed a "backorder July" notice posted with the HEL80 on powernotebooks site. Is this still standing?

Thanks

 

The LCD specs have not been published yet, so there is no way to get them unless someone wants to take it apart and get the manufacturer and part number.

Both the PowerPro L 8:15 and Crown P 15:2 are in stock and shipping daily. Where did you see the "backorder July"? Let me know and I will fix it. (Have you refreshed your page recently?)

 

Thanks for the quick reply.
Sorry it was actually the PowerPro A that had the "backordered till July" under the monitor choice on the customization page.

 

Yes, those are still back ordered for another 2-3 weeks (let's hope it is only 2 weeks! )

 

steam reports my HEL80's WSXGA screen (1680x1050) as manufactured by seiko/epson... so thats a start.

 

Well, without detailed specifications which can often be deceiving anyway...what is your impression of the viewing angle (side to side and top to bottom), brightness (turn it all the way up) and contrast ratio?

 

Ok, here are the official specs for the Samsung model LTN154P1-L02 that is the WSXGA+ screen (1680x1050 16:10 Aspect ratio) on the HEL80.

Brightness - 185 cd/m2 (nits)
Contrast ratio - 300
Viewing angles - 130 degrees horizontal/100 degrees vertical
Response time - 25ms

 

Thanks Donald for those specs! It's right up my alley. So...the Power pro A's are a couple weeks away...hmmm. I wonder if the specs on those lcd's will be similar.

What's the difference between the Power Pro L & the Crown P if i could ask?

 

Samsung lists the contrast at 500:1 for the LTN154P1. Sounds like a fine panel, if not overly bright.

 

There is alread a thread on this question.

The answer is at http://forum.notebookreview.com/showpost.php?p=1459747&postcount=4

 

500:1 contrast is GREAT. Is that true Donald, or is it an error?
185 nits is not bad, but not so great... but I prefer good contrast (especially, dark blacks)
How dark does the screen get when you look at a black background?

 

Interesting.

I got my numbers from their original design specifications document from 3rd Qtr 2005, so it is possible that the spec changed by production time...OR, it could be that the website spec is wrong...OR, who knows...that's what I meant about these specs being deceptive.

Now, for some really great news. This Samsung LCD uses the new Prism technology. In summary, the technology is called LGP Prism and it projects light from the outside toward the center allowing for even display brightness compared to standard screens which project from the middle out. Essentially this is like comparing Trintron technology to grid technology on old CRT monitors. Even though they both have the same resolution, the picture quality is much different.

 

hehe...how dark is dark?

I never know how to answer a question like that...better to read my last post, and then wait until you get yours and then you can tell us your impression of how black the black is.

 

Well, just to further muddy the waters, the 2006 E-Brochure (PDF file) says the LTN154P1 has a 600:1 Contrast Ratio! All the other stats are consistant with what you posted and with what is shown on that web link I posted.

I read the whitepaper (thanks for the link!), and that's not at all LGP Prism does for you -- nearly the opposite, in fact. First, the CCFL (or LED) backlight is always at one (or both) ends of the screen in notebook applications. The difference with Prism LDP vs. a "normal" backlight is that they have replaced several layers in the old design (light gathering panel and diffuser) with a single one (a prism LGP) that bends the light a bit more than the old ones. This allows them to mount the prism sheet the opposite way as the old method ("point down" instead of "point up") and eliminate the diffuser. That get's them three less "bounces" or "bends", retaining more brightness. In addition, refraction caused further light loss in the old system.

According to Samsung, the new system "makes Brightness higher more than 20% [sic]".

The downside is that this method is less uniform than the old method. Samsung claims that this is ok, because the nature of the uniformity (or lack thereof) with the new system is different than the old system, so it seems at least as good, if not better, to most people.

So, this leads to a birighter, thinner, lighter display for the same power draw, giving up some (possibly unnoticeable) uniformity in the process. Definately a win for them, probably a win for us, assuming that their claims about the perceived uniformity of lighting hold true, or at least enough so not to offset the benifits of extra brightness and reduced thickness of display.

One thing I'm curious about is if this backlight system is related to the issues ( here, here and here, for examples in these very forums) people were claiming to have with this screen in the Acer 8204? Or perhapst that was an older revision of this screen -- hard to tell with the information I've been able to find so far.

 

Given the slow response time of LTN154P1-L02 what effect does this have on ghosting, particularly in gaming? this was asked earlier in the thread but i dont think it has been addressed. has anyone made the same complaints with the HEL80 wsxga+ as the ACER people have making about LTN154P1-L02? I find those complaints to be quite a troublesome...

 

No complaints of ghosting yet.

We would need to know a lot more about the ACER complaints to comment on them. How about which models, what video card are they using, what are the rest of the components, what are the core/mem clocks...and finally how about being specific (with some links) about where you have seen these complaints.

 

I believe azriyeti is referring to the complaints I asked about at the end of message 17, above, in which I link to a search showing several threads about it on this forum. If that link didn't work correctly, let me know, and I'll post several direct links.

 

Yea, ive seen them in a variety of forums. just google the model number of this LCD panel and you will see acerforums where it is mentioned. i think its in their 8204 with an X1600. The link in Sindisil's shbeal referring to 'issues' does not work.

 

Apparently search links on this forum have a limited lifetime - thanks for catching that. I've edited my "shbeal" to contain links to messages in these forums having to do with the problem.

 

Much ado about nothing...see Chaz's post at http://forum.notebookreview.com/showpost.php?p=1462923&postcount=16

No more worries

 

I must also say that the WSXGA+ screen on the HEL80 is a wonderful screen. I personally prefer the matte finish too having just owned a 17" glossy one previously.
