HP LP2475w (Possible new IPS)

Cool. It would be nice if you could get some dvds or tv/cable to see how the colors look on yours.

Hi

My problem is as follows. In gray scale gradients, I can see green/yellow bands. I took two very bad quality photos but that effect can be appreciated:

[The pink tint on the right side is due to the camera].

I've read this may be unadjusted gamma (I'm using tftcentral profile), but I'm not sure.

Could someone comment on this? Thank you

Did you adjust the OSD color, brightness, and contrast settings to match the TFT Central settings?

So, it appears to be the Bizlink DP Cable that's causing the problem? As opposed to the monitor itself? That's a relief, I suppose.
 
@vick1000
Yes, of course, thank you

Now I have an Eye One Display 2 + I Color Display software, and even doing fine-tune adjusting, I can not completely eliminate the banding.

From here: http://www.drycreekphoto.com/Learn/Calibration/monitor_gradient.htm

A very few displays can show the full black to white gradient with no posterization or banding. Most can not. Typically there is some banding in shadows and darker midtones.

Maybe I'm trying to do an impossible with this display. But what bothers me is the green bias of those bands.
 
I received my HP LP2475w last week, bought on eBay. It was manufactured August, 2008, in China with REV GIG 122, and F/W Version GIG 034. Although it has no dead pixels, it does have the green/pink tint from left to right. It is very obvious because my 20WMGX2 is sitting next to it, to the right. Whenever there is a body of white or gray spanning across the two monitors, I can see the pink on LP2475w.

Another issue is the warrantee. I checked the serial number with HP's web site. Its database says this monitor was sold in Nov/08, thus the warrantee runs out in Dec/11. I've emailed the eBay seller about a receipt to extend the warrantee, so far no response.

P.S. My monitors are color calibrated with Spyder3.

Care to give a further comparison of the HP2475w with the Gx2? (I'm looking to upgrade. 20" really is too small.)
 
@SalvaG

Can you describe the "bands"?

I see vertical stripes, more visible on the left (dark) side, on both of my monitors (LP2475w and 20WMGX2).
 
It's a cheap camera, without focus on short distances; the monitor does not show an appreciable pink tint.
 
thank you

you have a REV GIG122 | Firmware GIG 045, right?

Then it seems I have to call HP for a replacement
 
Hey fantastic, 2 people on this thread with both a NEC 20WMGX2 and an HP LP2475W, I have a question. How does the saturation on the HP compare to the NEC using the "Photo" preset? The Photo preset really oversaturates the image and reduce gamma a lot, making colors very pronounced. Would setting the NEC on that preset be similar to what the HP reproduces after calibration?

I love my NEC, but 20" is not enough anymore. I almost feel like it's shrinking somehow.
 
Hi, a few days ago I bought a brand new HP lp2475w and I found out that there are black lines (I can only see them recording the display with a video cam). If I set the brightness level over 90 those lines disappear. Is this normal? what do you guys think?
Here it is a link of what I recorded

Can you see those lines during regular use when brightness is below 90?

thx for answering. I can see the lines ONLY while recording with a video cam.

Then I would chalk it up to CCFL backlight frequency and the camcorder sensor frequency being out of sync. Much like you see with the 60hz scanning frequency of CRTs in movies and TV, where it shows a similar effect. The camera is capturing the screen mid-refresh. Cranking up the brightness probably increases CCFL output frequency or just washes out the image enough that it isn't noticeable.
 
So, this is my first post in about 4 years (haven't used this handle since then either lol). Be gentle. :)

Just had a quick question. I'm extremely interested in the LP2475w but I'm not sure it's right for me. I currently have a Dell 2005FP, and a Dell 2001FP side by side, I loved my 2001FP for the past 4 years. It has served me well, but it is getting really dim :( I'm planning to replace the 2001FP with the LP2475w and move my 2005FP to the secondary position. I just recently (last night) started learning about all of the different display technologies. If my research is correct the 2001 and 2005 are both S-IPS displays (according to flatpanelshd.com). Anyways, I'm just trying to figure out if I'll see a negative difference between my 2005FP and the LP2475w when it comes to gaming performance. I have never noticed ghosting or display lag on either of my LCD's in the past. I mainly play COD4. I would assume that a nice new LCD (LP2475w) would have no problem outperforming my current 2-4 year old LCD's. But, I just want to be sure before I shell out the cash.

Also, I do some amateur photo editing (very amateur, just typically messing with some of my pictures in lightroom). I've noticed that of my 2 displays, the colors they display are extremely varied (I also have an old crappy 19" Dell LCD, but I don't even consider it, b/c it is so bright, everything is kind of washed out). Anyways, I'm having trouble figuring out whether the gamut the LP2475w has will good or bad with the photo editing I do.

Thanks guys.

I haven't gamed that much since getting my LP2475W last week, but I did play a couple of rounds this weekend during Steam's free UT3 promo. That's a very fast-paced, twitch game if I ever saw one, and I noticed no ghosting nor any input lag (more the relevant issue with IPS panels).

I also played a few videos, both streamed and ripped, HD and SD, and everything looked fine. At first I thought it was going to be a no-go for video, because in the Dead Space extended trailer I was watching (via Steam), the colors in their faces looked terrible -- then I played the video on my 2407wfp and it looked the same. Everything else looked great, better than the 2407. Speaking of, I always thought my 2407 looked awesome, but seeing it beside this 2475 now makes me want to replace the Dell with a matching 2475...

For photos, wide gamut should do you well, as that is where it is most suited (just be sure to calibrate as best you can).

I don't get all the hate around wide gamut monitors like the 2475, I guess it's just a subjective thing. I personally think it looks great. I like colors that pop, and for that reason had the brightness cranked and nVidia Digital Vibrance bumped on my 2407, so it wasn't that much of a leap for me to go to the 2475.

thx for answering. U probably are right, but I didn't noticed this effect in the video of this monitor recorded by other people. I can't see this effect in my other monitors either. So I wonder if my monitor is faulty


Then I don't see what the problem is. Do you use your monitor through the video camera?
Click to expand...

thx for answering . I don't use the monitor through a video cam, but when I stay for a while in front of the monitor, I feel a bit dizzy and my eyes start to weep, thing that I only experience with this monitor.

CCFL cycling is all that is, nothing special, you just have a fast video camera.

thx for answering . If that was the reason, black lines wouldn't disappear when I set brightness level to the top, as can be seen in the video

Excellent! Thanks so much for the information. Now, I just need to find one below $600 :\

I suggest you invest in a colorimeter to match the colors of multiple monitors. If you buy a LP2475w or any wide gamut monitor, then Spyder3 is probably your best bet. Although its software isn't the most sophisticated, it's sufficient for amateur photo editing.

Thanks for the information. That thread really opened my eyes to the issues and solutions to wide gamut displays. I'm starting to question whether this is the right LCD for me. It seems like the only color aware app that I use regularly is Firefox (and probably lightroom). I would hate for 90% of my stuff to be oversaturated. And even if it can be fixed, I'd hate to always have to deal with custom profiles and such. It would be really nice if Windows 7 (I'm currently running the beta) was already out and we all knew if it will be truly color aware.

Anyways, in light of my recent awakening as to what wide gamut truly is...Do any of you guys have recommendations for LCD's similar to the LP2475w that are not wide gamut? I was really deadset on the 2475w but it's hard to justify the price if I will constantly have to deal with wide gamut. :(

Thanks again for your help!
 
Today I received the replacement. I first looked at the revision it is the same as the one it replaces, GIG111 made in Czech Republic. But the replacement is older and has firmware 034 which is also older then the 045 it replaces. But the screen is much better, de backlight does not have the green tinting issue like the previous sample has. Although this sample also has some light falloff near the edges most noticeable on the right side. Similar effect like lens vignetting, not really a big issue. My conclusion so far is that there is absolutely no way of telling which revision and/or production date is best. Simply a matter of luck.

Yeah, I saw that link. It worries me that he lists the resolution at 1920x1080 instead of 1920x1200. I guess if I can't find a comparable LCD without the wide gamut, I'll just go ahead and order it. I'm able to get it through CDW for $580. Too bad Dell doesn't sell it, I could get a much better discount there. :(

Argh, I want this LCD so bad, but at the same time, wish they had an option without the wide gamut.

A lot is made of the wide gamut issue, but honestly, if I hadn't known it was wide gamut I probably wouldn't have noticed. If you look for it, you can find some over-saturation, but for normal day to day use I don't notice at all. Granted, I took the time to calibrate mine, and never really used it without calibration - but if you are going to spend the coin on a monitor like this, you really should calibrate it.
 
What would you recommend between LP2475w and Samsung T240HD ? I'll use it for my PC ( games,internet,movies) and for the xbox 360 as well. What about pixel mapping 1:1 ,on HP LP2475w ?When i play xbox games,does it strech the image? Please give me some advices,cheers.

Completely different classes. The LP2475w is an H-IPS panel and the Samsung is a TN panel. If you're just using it for gaming, you probably will be content with the T240HD. I would also take a look at other cheaper 24" monitors (Acer, ASUS) that are just as good.

Would a Spyder2 do an okay job? I can get one for less than $100. I agree that, especially with a monitor in this price range, that after market calibration is damn near necessity ... I just don't want to spend a ton to get 'er done.
