What would you do if you suffered from a hard drive crash and had to re-do all those 27 pages? j/k

Make sure you've got a backup cause it would suck like none other to lose 27 pages of work... hehe

 

[KristopherKubicki]

Ugh 30+ Pages. Hehe, I have been doing this too long to know that everything gets backed up.

Im probably going to cut the article in half with as "Part 1: Technical" and "Part 2: Overly Technical". =)

Kristopher, when is your 192t review gonna be up?

 

[KristopherKubicki]

Gary, Looking to be today or tommorow. Anand has some "secret" things he is working on and we usually try avoiding posting 2 things on the same day. If I dont hear from him today you can expect to see it go up in the wee hours of the morning.

Analoge vs. DVI issue!! Some people say they can't see a difference but for others it is like night and day. I have found that the Video card used could also be a contributing factor of the display quality in Analog or DVI.

Example 1:

A friend of mine has a Smamsung 191T on DVI with an ATI Radeon 7000 and the screen quality is sharp and very clear. When hooked up to Analog personally I can't see a difference in screen, text graphics quality. Maybe newer LCD's such as the Samsung 191T don't suffer as much from quality loss when hooked up to Analog??? However, I never tested the 191T with any other graphics card.

Example 2:

I have a Gateway FPD1830 18.1" LCD on DVI wih an ATI Radeon 8500 and screen quality a great and crips. On Analog text quality is crap and the LCD has a blue look to it. This is also true when I hook up the Gateway LCD to an old Voodoo 3 3000 16MB AGP card. Screen quality looks like crap.

I personally think the video card used and how new the LCD is palays an important role in the Analoge vs. DVI discussion. If anybody has simmilar findings please post.

thanks

Hmm... The amount of EM in your room, the quality of the VGA cable and the quality of your card all have something to do with it. My friend is running 2 Hitachi LCD's side by side on a 9700 pro and it looked fairly ugly with the regular VGA cable. He got a shielded cable for $10 and it looked a lot better. You can still tell the difference but its bearable.

Thanks. Good review.
In the review you said the 192T and the PX191 were almost identical. What differences are there? Since the PX191 can be had for $685 right now and I would have to wait for the 192T is there any reason why I should wait?

I think the px191 and the 191t use the same panel from auo optronics. The 192t has better reds/colour definition, and has a 5/5 mark on streaking/ghosting...so probably games and movies will be enhanced in comparison to the older version and px191. The 192t has a less effective anti glare screen then the 191t, but logically has a better image quality due to certain sacrifices in anti glare. Looks as if the 192T has a more efficient response time aswell...considering the 5/5 mark for 25ms.

Gary:

I am pretty sure all 3 monitors use a substrate from Samsung. I'm going to open up my 192T in a few minutes though to make sure.

As for the 5/5 marks for streaking/ghosting - check your PM. That is the literal definition of streaking from the VESA handbook. It refers to image degration over the signal - rather than motion blur.

Kristopher

What is the rating on motion blur? Or your personal opinion on it...

 

[KristopherKubicki]

Well its hard to say because its a subjective analysis on something like that. The black to white response time was very good and near par with the Hitachi CML174. However, gray to gray, like with a mouse cursor over a green or blue background will result in a barely noticable trail. In my opinion, not enough to discourage a purchase - but if you live and breath quake then it might be something you have to consider.

Hi,

Did you post the FAQ on LCD monitors? I really want to get at 20+" monitor for gaming and personal use. Will your FAQ address this? I am willing to spend $1200 for a good one. I want quality.

Thanks,

-Kirk

 

[Baileybbk]

What is the DVI max cable length?
Are there extenders around for it yet?

Response times:
- Importance of Black2White, White2Black, Color2Color (Grey2Grey)?

Also, are there amplified splitters for DVI yet? (so one can run a projector and LCD off the same output)

Kristopher, remember that thread on the 16ms 20" LCD from LG? well...considering nobody clarified its spec can you tell me if this monitor does actually have a 16ms response time? even though it has a 20" screen? im guessing if it is valid then the panel isnt a AUO product.

LG informed me that they do make a 16ms response time panel but this particular one is not it. You can always tell if its a LG panel if it uses the IPS or Super IPS mode. That being said, you can always spot a Samsung substrate if it boasts a PVA mode.

Hope that helps

So there lying in order to boost this products sales? And the 16ms is obviously the 17" one right?

 

[JZilla]

And yet they list it as 16ms. Sigh. It seems to me that these LG people are confused, or maybe it's just marketing at ït's best.

I think there trying to cash in on the naiveity of LCD consumers, hehe they probably lunch with viewsonic.

 

[toeng]

For LCD, I'll stick with Samsung. They have been one of the best in the industry for so long and their customer service is supposedly among the best ones too.

 

[KristopherKubicki]

Jzilla - perhaps.

toeng: LG is no small company. They are the largest producers of substrates in the world. With the exception of sharp and samsung, they are also the only company working on 6g production as well.

Kubicki,

How about you write a powersupply faq after the lcd faq and the psu review. Not a day goes by without a "will 300w be enough" in GH. Firingsquad has an excellent guide on psus, which I usually refer people to. It's the guide that gave me my wisdom (yeah right) about psus.

Could you briefly explain what 6G means. I have seen it mentioned before on digit-life.com. I take it 6G means 6th generation production facility. And that each generation allows more effective production of substrates. Please correct me if I am wrong.

I stumbled at this over at x-bit labs the other day. Seems a little strange to me, but then I am not the expert. But maybe you could use this in your reviews, togethet with the Spyder.

 

[KristopherKubicki]

Jzilla.

Thats an excellent Idea. I will do that after the LCD FAQ. Firing squads guide is ok, but it has a lot of holes.

6G means sixth generation. Its kind of an uverused ambigious term, but it basically refers to "large" substrate production facilities. For example, Sharp's 6G facility is for TVs only. Samsungs will be for 30"+ substrates on 60" motherglass. LG is following similar suit i think.

The Xbit labs thing is kind of intersting - but really doesnt prove anything. The more important thing that LCD manufacturers are going to start stressing about is grey to grey response time. In any case, its nice, but not particularly helpful - when/if we build a device that can do grey to grey then perhaps we can use that.

Hope that helps,

Kristopher
