Banding can occur on any panel at all, and it's usually due to digital "enhancement" features that can't be turned off for whatever reason.

I doubt what you're talking about is really banding. It may be gradation or discoloration. The only way to really reduce it is to get a colorimeter. Anything else is rather futile. I would not highly recommend adjusting gamma in a non-linear fashion on your own (it usually makes things worse), but nevertheless I have a guide on my website of how to do it with RivaTuner.

Thank you for the useful tips, as always. Actually adjusting the gamma did make it worse, after I returned to the previous settings the gradation was significantly reduced. I can still see it on gradients, but I guess I'll live with it until I buy a colorimeter.

I have one more question related to heating: my monitor (HP LP2465) gets really hot, especially at the top. Even the actual display gets hot (not as much as the back, but still is pretty warm). Should I be worried or is this normal for a monitor of this size? Until now I had a crt with ice cold display.

thanks again!

Color accuracy is not consistent from monitor to monitor especially when at the factory default settings.

As for the banding...what gradients are you using to judge the banding issue?

i have a question, i don't intend on buying a ARDWARE calibrator, is it possible to get decent colour accuracy on the Dell 2408 via software methods? I don't need perfection, just a decent accuracy is fine for me

Provided one loads the included profile from Dell and uses color managed applications...yes.

Does the dell 2408 rev A01 do that? cuz that's the one i got.
Also, although the monitor has 1:1 mapping, if i put it to display 1920x1080 res for my ps3, will it fill the entire screen or would i have black bars?
Thanks for taking time to reply

The Dell has nothing to do with it. You have to install the color profile and you have to choose to use applications that are color management aware.

If you set the display to 1:1 mapping, yes there should be black bars. If you set it to the normal setting then no there will not.

I'm about to buy a new monitor.
I'm working with graphic of every type.
Web, Photo, Print and mainly Video.
What monitor should i look at in your opinion?

HP LP2475w?
Is there something newer and better?
Thank you.
I have no budget but I'm looking for the best cost/quality compromise.

It depends.. LP2475w is good but if you are willing to fork over a bit more cash, the 3007WFP which is a 30" monitor can be had for $850 refurbished. Since the resolution is 2560x1600 that gives you around 70% more space to work with. Great for working with print and photos.

If you don't need the extra space then go with the HP. It is the best deal for a 24" IPS.

Wow, this is a tough decision...

I want a 24" / 1920x1200 / FAST- lots of FPS- Call of Duty5 online with son / good to very good color accuracy... / budget upto $575.

We currently have the Dell 20" model # 2001FP...


My 'basket' of choices...
BenQ G2400WD... fastest but quality color?
Asus MK241H.....Not as fast but a step up in quality?...
Asus VW266...
HP LP2475w...a bit slower, but much better color, etc...


AND, the UNKNOWN....the new Dell out next month? The LG W2420P...

Which? Or, do you like a substitute that's not on my list?

VX2260wm ("other" model)

Thanks, I just managed to find a LG Flatron L227WTG-PF so I am pretty happy[/quote]

%&&% they sent me a LG 227WTP

They can't get the L227WTG

Hi,

I am looking for a photographic work monitor, with a budget of 650?.

I own an X-Rite i1 Display 2 colorimeter and I am familiar with color management.
Since I plan to buy a large format inkjet printer, I consider both sRGB and "wide gamut" monitors.

I spotted the following models:

  1. EIZO FlexScan S2242W (~550?): 22", 1920*1200px, S-PVA, "wide gamut" (95% of Adobe RGB).
    HP LP2475W (~550?): 24", 1920*1200px, H-IPS, "wide gamut".
    NEC MultiSync 2490WUXi2 (~750?, exceeding my budget): 24", 1920*1200px, H-IPS (without A-TW polarizer on this new version), sRGB, hardware calibration possible.
Open to any suggestion.

I am a bit discreet concerning the potential benefits of H-IPS panels, without A-TW polarizer, over S-PVA panels.
Actually, I owned a Dell 3007WFP-HC and I noticed very important black level variations depending on the viewing angle. Uniform dark backgrounds looked like "shiny surfaces". My previous P-MVA and S-PVA monitors performed much better on this aspect.
On the other hand, half and dark tones brightness and color were pretty consistent whatever the viewing angle. No gamma or color shift like on my previous P-MVA and S-PVA monitors.

Therefore, I'd like to get some experiences, reviews or even photographs that illustrate the potential benefits of H-IPS panels, without A-TW polarizer, over S-PVA panels.

Many thanks for your help.

Let me just stress how nice hardware Monitor LUTS are in a windows environment. Windows likes to do things that "throw out" the LUTS loaded into the video card. When I just used a Spyder 2 with CEDpro calibration software I noticed that my calibrated LUTs would be discarded if UAC messages come up(this is very documented...not just a glitch with a single setup. I also noticed that they would be discarded when loading some games. The problem isn't that I would lose them in games(can live without perfect calibration there) its that you don't always notice when they've been discarded. Then you go and work on photos and your greyscale is all out of whack.

For this reason I purched the NEC P221W. It has a built in 10bit hardware LUT. I now use a Custom calibrated for NEC wide gamut monitors i1 display2 colorimeter with NEC's spectraview. This software writes the LUT to the monitor where it can't be touched by the operating system. It's so nice to know that my LUTs never get "discarded" now.

I've been looking for a quality 26-27" monitor used primarily for gaming but also regular office type of work and some video viewing as well. I live in Europe, to the Planar 26" which seems to be a good performer is not available it seems.. After looking around a bit, I've found some favorable reviews of the LG W2600HP-BF.. But it's not on the list at all here on the forums.. Anyone have some input on this screen?

Has anyone successfully used the 'eZ Zooming' feature on LG monitors? On my dad's L226WT it will not work whatsoever on VGA or DVI. On my L227WT, it won't do anything, either, although I didn't try VGA. Manual says nothing special. This is how it's supposed to work:

At the current display, Use 'ez Zooming' Key, then the display
resolution is transferred to the one step low resolution.
Use 'ez Zooming' Key one more, the display is back to the
original display.

I'm wondering if this just flat out doesn't work on everyone's LG unit(s).

I did read this at a different forum,

Download forte manager to get ez zooming to work, all the monitor controls can be adjusted through forte manager.

So maybe try latest version,any luck with that?

Thanks for the advice. I'll have to try this.

Thank you for your advice xtnight, i bought the Dell 2408 based on what you said, hopefully i would walk away a happy man. One thing thoug after checking some reviews i see conflicting information. Anandtech states that the monitor before calibration i s better than monitors after calibration averaging around 1.7 dE, however tftcentral states it's colour accuracy is awful at factory settings. Am i missing something here? who is correct?

A lot of review sites have differing info when it comes to deltaE. I suspect they may get units with different settings, or maybe even some of them change the settings before they measure "before calibration".

The 2408WFP's default colors certainly are not bad. They should be good for most use.

How would you rate the 2209WA vs 20WMGX2?

Both are S-IPS panels. The 20WMGX2 may have more contrast and it has a finer and glossier looking image. The 2209WA may not have an A quality panel. It might not have quite as deep of a black. Mostly a guess, but the glossy thing is definitely going to be true. Both are standard gamut so no big difference there, and no big difference in response time although perhaps a slight edge to the NEC.

You probably don't need to worry about it. These displays are built to withstand it. If you have a problem, it's on HP. You can put a fan or some sort of heatsink on it if you really want but I don't think it'd be worth it.

If this is old news please ignore, the search feature has not been working.

Nope, not old news. Interesting though thanks for the link. Let's be warned that many LCDs introduced in press releases don't come to the US and that this is a PR from NEC Europe (source). Of course, that's great for Europeans.

The LP2475w, since it encompasses the gamut of your highest-gamut activity (Print).

Keep in mind to use color management for any sRGB photos.

I would pick the HP in this case. The Dell 2408WFP and G2400WD are also options. I'd pick them in the order I listed. The HP may be a bit faster than the Dell input lag-wise although I'm not sure about that. The BenQ would have considerably limited stability of the image (viewing angle), although it would have virtually no lag and would have a slightly faster response time. I still think the HP is better for most people, even gamers.

xtknight...

That Dell and the BenQG2400WD are off the table now. I want something better, so, these are my choices I guess:
*The HP 'LP2475w'
*The 'unknown', new, due in August, Dell 24"...(supposedly an enthusiast model)
*The LG that everyone hopes will be distributed here, the W2420P...

In reality, how much of a difference can there be among these 3 monitors? I don't know if I can wait thru the month of August for those other 2 monitors...

Ok I've finally got about $600 saved up for a 24 inch monitor. Now which one to get? I'm a gamer and I also like my colors to look sharp and accurate. Which monitor would be best for below $600? I would like and IPS or PVA. Or should I wait a bit for some new monitors coming out soon?

Hah, where have I seen those comments before...why, there they are in the post above yours...

That's the $64,000. question...

Now, for me...3 choices:
HP 'LP2475w'...available now @ $517.-$600. range I believe...
The LG 'W2420P'...not available here in US / MAY distribute it here...
The new Dell '2410W'... not out yet...rumored to be out end of August...
