I have seen no official information stating whether this panel is H-IPS or S-IPS. I contacted their sales department but haven't heard back from them yet. Does anyone actually know the panel type of this 30 inch?

On a side note, if it turns out to be an S-IPS, would I be better served getting a 26inch H-IPS panel instead of the 30 s-ips? I'm coming from a dell 2007wfp s-ips (20inch) and I mainly game on my monitors, however I will only use IPS. I have a 4870x2 so the 2560x1600 would be fine, but if an H-IPS gets rid of the black turning to purple/green hue on angles, that would be nice.
 
It is an S-IPS, though I do not know which S-IPS. You will have to read the specification to figure that out.
 
It's H-IPS. LG doesn't make 30" S-IPS panels anymore.

Why does it matter anyway? S-IPS and H-IPS perform very similarly. H-IPS does not get rid of the glow. H-IPS and newer S-IPS panels glow white at an angle, while older S-IPS panels glow orange at slight angles and purple at extreme angles.

Only monitors with the A-TW polarizer don't have a significant glow, but only a few monitors have it:

NEC LCD2490WUXi (2 frame lag)
NEC LCD2690WUXi (2 frame lag)
HP DreamColor LP2480zx (1 frame lag, expensive)
DoubleSight DS-263N (no lag, but only some units had the polarizer)
DoubleSight DS-265W (no backlight control, so black looks like crap anyway)
Hazro HZ26W and HZ26Wi (no backlight control either)

That's a complete list as far as I know. None of the 30" models have it. The DoubleSight DS-263N with the polarizer was the best bang for the buck, but it's not available anymore.

I'll make the decision easier for you:

Higher resolution + no lag + white glow = DoubleSight DS-305W
Lower resolution + 2 frame lag + no glow = NEC monitors

Which do you care about more?
 
How do you know if it's an H-IPS panel? Is there a source?
I am not sure about LG stopped making 30'' S-IPS panels. They are currently selling the panels to just about any individual in Korea, where the HQ is located. Most companies(Small companies like Hazro) are selling the latest Q5 panel(Same as Dell 3008wfp) completed in an anodized aluminum casing with DVI ports for just $500. I think Microboard is one of them, but their price is a little higher than others.
The bare panel can be had for $370 or possibly even less. They have way too much in stock and still continuously selling different panels including A4, Q3, and the latest Q5 to individual sellers.
Did they stop making these because they have too much in stock? What is the reason?
 
You just answered your own question. The DoubleSight DS-305W is the same monitor as the Hazro HZ30W, which you say has the latest Q5 panel. The Q5 panel is H-IPS.

I haven't seen a new monitor with an S-IPS panel come out in a long time.
 
Thanks for the good information Toasty. I'm really more interested in resolution, but for showing off the monitor the purple glow at angles is a distraction ( also bad for movies ), but, as long as I get the latest H-IPS in the 305W I'd be satisfied I think. My only other option is to find a 263N and lose some res, but I think I'd always have buyer's remorse about the lack of full res. Any 30 inch panels on the horizon with A-TW Polarizer?
 
This is the response I got from Doublesight in regards to the panel used in the 305w, according to them, its an S-IPS.

Thank you for your interest in our Monitors. The DS-305W is built with an S-IPS panel.



It is in stock and available from a variety of Resellers. Here is a link to some of DoubleSight’s top retail partners: http://www.doublesight.com/purchase/us/

"S-IPS" is often used as a blanket term for any type of IPS panel.
 
That may be, but I asked him specifically whether it was an H-IPS or an S-IPS in the email as the difference would matter to me. I would expect his answer is correct. I'll believe him over someone on the forums who says "LG no longer makes S-IPS Panels". This coming from someone who doesn't work for LG. Not to mention, there may still be a stock of S-IPS panels or doublesight may have bought a bulk load of S-IPS for their 305W. There are many scenarios, and I'm going to bet on the DS representative being correct.

If we really want to find out I guess I could either find out a way to get into some diagnostics menu on the display, or I can take it apart. I got the display through buy.com's ebay account for $750(live.com search gives $200 cashback on ebay purchases via microsoft cashback). Sold my dell 2007wfp for 365 on ebay so the upgrade from 20 to 30 cost me $385 :) Can't beat that.
 
You put too much faith in sales representatives. He also said that the DS-265W would have HDMI and that every DS-263N had the polarizer. If you're not sure, you shouldn't believe anyone until you've verified for yourself.

Perhaps "make" isn't the right word. What I mean is LG hasn't released any new 30" S-IPS panels in a long time. I'm sure they have residual stock, and it's possible they're still producing some older panels, but the DS-305W doesn't have one of those older panels. It's definitely H-IPS.

The panel type can easily be verified by taking a macro shot of the pixels. S-IPS panels have pixels shaped like << or >>, while H-IPS panels have pixels shaped like |||.

You shouldn't believe a Doublesight representative if he tells you the sky is blue. You must not have very much experience with this company, and I say that as a satisfied owner of one of their monitors.
 


Looks to be H-IPS after all. Great monitor so far. No dead pixels, although the box had a hole punched in it that made the panel literally open to any hits (its just cardboard then about 5 inches of space and then the panel. DS should put a cross brace of foam in there, it would add very little to the price and probably reduce returned monitors.
 
I'll write up a full review eventually here, but just some initial impressions:

First off I'm coming from a 20 inch s-ips dell 2007wfp, my roommate has a 30inch dell 3007wfp-hc which I've used before.

Viewing Angles:
The monitor is amazing for watching movies or any off center viewing. Since its the new H-IPS there is a slight whitish glow on blacks that are off angle, but I prefer this to the green/purple of my previous S-IPS.

Gaming:
I'm a very hardcore gamer, I play competitive CSS and am very sensitive to input lag or ghosting. To my eyes, I see 0 ghosting, and 0 input lag. Since this panel is very similar if not identical to the hazro 30inch, I'd bet the input lag is 7.5ms (which is less then half a frame of input lag when you consider 1/60s being 1 frame). Either way, the monitor is absolutely perfect for gaming, regardless of what type of games you play.

I also played some stalker clear sky, supreme commander forged alliance, tf2, grid, etc, and you will just be floored by the way these games look on a beautiful 2560x1600 panel running full speed. (4870x2)

Colors:
I applied the ICC profile for the Hazro 30 and the colors look great. I can't put any real numbers on it, but the panel looks great.

Look:
The aluminum framing is very modern and appealing. I don't see any backlight bleeding.

Now take into account you can use the microsoft 200 dollar cash back on this monitor to get it for 750ish on ebay (buy.com's ebay account), it is an absolute STEAL. Sure it lacks any inputs past the DVI-D, but that is all I need anyway and if you really want to use your xbox or ps3 on it just get an hdmi-dvi cable from monoprice for <$10.

The biggest problem is the box this monitor comes in. My monitor's box had been kicked in but luckily the monitor was unharmed. That doesn't excuse the fact that there is literally 1/4" of cardboard and then 5 inches of open space and then the panels front face with a blanket around it. I don't like there only being 1/4" of cardboard between a $1000 panel and possible damage. Make sure you check the monitor before you receive it from your shipper in case its been damaged.
 
Not sure why, but I guess HardForum doesn't retroactively update your signature. I'm just posting so you guys have an idea of my specs for reference.
 
Well it looks like the HP is S-IPS, so green/purple hue on your blacks when viewing at an angle. Don't know what your priorities are, so that makes a big difference. For me, I don't need extra inputs and snaz, and I like the fact I got a new 30 for 750 with a very up to date H-IPS panel with 92% NTCS gamut. You know where my money went :)
 
I hear that the DS-305W has horrible out of the box color, but when calibrated with a colorimeter has some of the best color that has ever been measured. Are you satisfied with the color?
 
Well the article you are referring to I'm sure is the tftcentral.co.uk. I looked at the same article since it was a review of the hazro 30 and the doublesight 30 looks identical to it. I am absolutely satisfied with the colors of this monitor. I applied the ICC profile for the Hazro 30 ( calibrated color profile for the hazro 30 ) which should bring my DS 305W very close to calibrated colors since I believe they use the same panel. I don't have a colorimeter to test this, but I may buy one someday :)
 
is it a 92% gamut screen though or 102%? the Q5 is 102% and 5ms G2G response time, whereas the Doublesight spec seems to match the Q1 or Q3 panels from LG.Display better (assuming it's 92% gamut)
 
Well, were the Q1/Q3 panels S-IPS or H-IPS? This panel is definitely an H-IPS so if the Q5 is the only LG H-IPS, I guess it's a 102%. Where are you getting the information about the LG Panels? I searched their site and came up with nothing.
