Do you see any unevenness on your LCDs (especially the NEC) on this viewing angle test

It seems that the 23 inch apple cinema display (another IPS) has this problem as well.Link with picture. I also took a closer look on the monitor I have at work which is the HP 20 inch non widescreen IPS and it wasn't entirely even either.

It can't be a problem on ALL IPS though since I tested a blank white page on Safari and there was definitely no tint.

The NEC IPS panels aren't with me at the moment. But, I do recall the LCD2690 had some sort of pinkish effect on those lagom tests (and yes, green as well, it was a "dipole" type effect where it went from pink to green depending on the angle, like a gradient with two polar ends). Its default uniformity was nothing to brag about either. But, the way I see it....the post is sensationalism. He's taking back everything he said about the LCD just because it's a tad bit uneven? I think we all need to take a step back and relax. Maybe his picture is underexposed, but usually pictures exaggerate the effects and I don't see much to be concerned about there.

The likelihood of these problems being fixed is extremely small. They're probably problems with the IPS panel itself and viewing compensation film. Nothing Apple or NEC can do. So we will have to live with the problems unfortunately.

I think it shows up more on gray/neutral colors (much like the horizontal lines of my H-IPS panel). It's definitely not obvious on white.

Hi Zebo, nice to see you around again

japinard, yes, I saw the HP LP2475W. IMO, it's the best choice if you can't get/afford NEC 2490WUXi or 2690WUXi. It's responsive, has excellent viewing angles, quite well adjustable colors and moderate/non-intrusive input lag. The price makes it a very good choice IMO. Quality control seems a bit hit or miss though, quite a few users report the infamous pink->blue/green hue shift and blurry text.

I chose the 2690WUXi because of 3 reasons:

1. Larger pixel pitch = more readable text. Although my eyes are still good, I prefer larger fonts and "2D" UI elements in games. On 24-inchers the pitch is OK but 26" is more comfortable for me.

2. Wide gamut doesn't seem so hard to handle on the NEC. The HP really oversaturates colors, particularly reds. Photos or movies look much better on the NEC "out of the box". The HP requires a lot of work in terms of desaturating colors/adjusting/calibrating, the NEC IMHO does not. It's much more neutral, WG isn't as troublesome here.

3. I really like the A-TW polarizer. IPS blacks tend to be greenish or pinkish when viewed from suboptimal angles but on monitors without polarizer, darker tones also get a silvery, milky veil, even if the angle isn't too extreme. The NEC does not suffer from the latter, thanks to the polarizer.

I'd say give the HP a try, it's the best monitor in its price range IMO. LG W2600HP is also a decent option but it's quite a bit more expensive. I can't get a Planar, Hazro or DoubleSight in Poland but they may be worth a shot as well (especially the Planar, if you're in the US).

Hey fyleow, sorry I did not reply sooner but no, I have not yet received my new panel. I'm pretty sure it's gonna take at least another week but I will report back as soon as I get it. I'm thinking it will be like you say, probably a similar issue but to a lesser degree.

The problem seems to be less now though it is still there. Maybe I just got used to it though...

I have the LCD2690WUXI as well and other than about two inches of slight pink tint to the letters on the left, I don't have any issues on the viewing angle test. This could possibly be due to the special A-TW polarizer on the NEC which can have a slight reddish tint on the left side when viewed far from the right. The grey itself does not turn pink very much for me on the left though, just the letters in the "gamma" viewing angles test (the first one on that page).

There are a few HP LP2475W users with this specific issue to varying degrees over on HardForum.com so it is not unique to your specific unit, methinks.

Seemingly, this is not just an IPS, nor specifically this IPS panel's problem, as it has also been discussed with the Dell 2408WFP which is S-PVA, and for a few the 2709W as well, (again S-PVA).

You may want to address with HP if it's a big enough problem for you. Apparently it is a "business monitor" so you need to talk to the business support line (I know it's already been mentioned earlier in this thread).

Good luck.

My older MBP seems to have similar viewing angles, and my mom's macbook seems to have even worse viewing angles than mine, and my MBP screen is a TN, so I don't think the new ones are IPS either.

All this work on finding the right LCD makes me have a headache. It just shows you how behind LCD monitors are. Look at LCD HDTV's, they look amazing and most of them use IPS panels. They are dedicated to showing video while LCD monitors struggle. Makes you wonder if you should have a dual display using a cheap LCD for regular use and a large HDTV for gaming and movies.

Most of TVs are using PVA panrels because they are cheaper and Samsung is a big player in that game, and they don't make S-IPS.

On both my monitors I have tiny issues with the Grey text screen and purple however I tried to DL image and to move them around in another image app but author hides it. RGB all look perfectly uniform. I am skeptical of the authenticity of first two images since they view same on both monitors.... damn I wish I still had my NEC Diamondtrons. Anyway the purple does not go to blue like author states but show a slight pinkish tinge in some sectors (left and right) And the text 'lagom' fades a bit left and right. Keep in mind I am picky though.

I hope I am not violating Forum customs by posting my questions here.

I'm about to start banging my head against this keyboard. I've been looking for a monitor that meets the following specifications, but I CANT AT ALL FIND ANYTHING!

-Non-TN
-24"+
-Minimum: HDMI and DVI inputs
-Refresh/Input lag good enough to play FPS games online.

I've scoured forum after forum and Google search after Google search, but still have not had any good results. I can come close to finding some IPS and PVA panels that have good image lag, but they are misisng HDMI or are 20". :x

I need the HDMI for by Xbox 360 and the DVI for my box. I've found some that are like $1,100, but that is too expensive. For that price I might as well buy the Samsung 46LN650 I've wanted for a while now. I don't mind laying some money down, ~$600, but that is straight up ridiculous.

Thank you for any help!!

Edit: I really like the HP LP2475w. Will I really notice the 1-3 frames of lag (AVG: 32ms)?

I also forgot to say thank you to xtknight. This is the best resource on the web for solid information. It seems like in every forum I go to the monitor forum is the least updated and the hardest forum to find information in. Thanks for keeping this updated.

(LP2475w)The lag will probably be slightly noticeable, it depends on your perception of things. Besides FPS gaming, that monitor is nearly perfect in every other way. If you can buy it from a large retailer, you will be able to try it out for 14-30 days and still be able to get a full refund.

I have no idea how return policies work on the web though.

Hey guys, I just wanted some recommendations on a 24" LCD monitor. I'm going to primarily use it for gaming and other basic stuff (word processing, net surfing, etc.), so I'm not picky about whether it's a TN panel, since I'm not going to be doing any graphics editing. I'm trying be as cost-efficient as I can, as I'm also building a PC to go along with it. Two models have caught my eye, the Samsung 2493HM for $349 and the HP w2408 for $400. I was wondering if the HP was worth it for the extra $50 bucks?

Here's the summary:

"For a 24-inch model with an S-IPS panel, the price of ? 550.00 is a downright bargain. The features and high-quality colour reproduction make the model an insider tip for graphics workers with a small budget. Even more demanding users who do not want to have to deal with the viewing angle dependencies of the widely used TN panel will take pleasure in this model.

Overall rating: VERY GOOD"

Wow, 16-page review and they didn't mention anywhere whether it has an anti-glare or glossy screen treatment.

That way I should be able to afford the more expensive 2.4GHz Macbook. Enough with the chat, I've browsed around at a local store and here are the displays that caught my eye:

- Samsung 2223NW - 22'' - 1680*1050 - 169 euros
- Philips 200CW - 20.1'' - 1680*1050 - 159 euros
- AOC 2215Sw - 21.6'' - 1680*1050 - 159 euros

There's little information about these monitors on the web. Just the one PC Pro review for the Philips monitor (http://www.pcpro.co.uk/labs/206880/philips-200cw.html). The Samsung and AOC monitors only seem to support D-SUB. I'm not sure how much of a problem this might be for my limited requirements. Additionally, I'll probably want a VGA adapter for connecting to overhead displays. So even if I bought the Philips monitor, I might still opt for using D-SUB anyway.

Is anyone here familiar with these monitors? If not, I'll probably go with the Samsung because it's the prettier one.

Sorry, I'm really not familiar with any of these. They are not available here in the US. I'd give the Philips a try since it's DVI. VGA doesn't look so good at 20" and over, depending on the source. Laptops are usually not the best VGA sources.

Yeah it does sometimes make me wonder. I doubt that LCD monitors will ever adopt as many IPS panels as TVs.

AFAIK many TVs still use LG Philips IPS panels and panels from IPS Alpha, Ltd. And there are still many advances like 120 Hz/180 Hz: http://www.ips-alpha.co.jp/en/technology/wxga.html

So are there any IPS LCD TVs that can compete with LCD monitors?
I'm having a hard time trying to decide between the Planar PX2611W 25.5" or a larger LCD TV with an IPS panel.
