Introduction
We've taken a look at several high-end 30" LCDs recently, like the HP LP3065 and the Dell 3007WFP. While these are undoubtedly nice monitors, many people have a few concerns with them. One of the major problems is that they require a dual-link DVI connection, so they essentially require a higher end graphics card than what many people have. Hooking them up to a notebook is also generally out of the question, with a few exceptions. They are also quite large, but with their 2560x1600 native resolution they still have a very fine pixel pitch. Some will think that's a good thing, while those who are more visually challenged [Ed: raises hand] might prefer a slightly lower native resolution.
Furthermore, while nearly everyone will agree that running your LCD at its native resolution is the best solution, gaming on a 30" LCD at 2560x1600 requires some serious graphics horsepower. Then there's the lack of input options on the 30" LCDs; due to a lack of any scaler ICs that can handle the native resolution, the displays only support dual-link DVI connections (or single-link with a very limiting 1280x800 resolution, with a few caveats).
This is not to say that 30" LCDs are bad; merely that they are not a solution that all find ideal. Enter the 27" LCD panel.
There are definitely people that would like something slightly larger than a 24" LCD, but they don't want to deal with some of the aforementioned problems with 30" LCDs. These people basically have a few options. First, they could always look at some of the 1080p HDTV solutions, which are currently available in 32", 37", 42", and several larger sizes. If resolution isn't a concern, there are plenty of other HDTV solutions out there, but those are less than ideal for computer work. The other option, and the one we'll be looking at today, is to get something like Dell's 27" 2707WFP.
We've already looked at Dell's 2407WFP and 3007WFP, so we refer back to the earlier review for anyone interested in additional information about Dell's other LCDs, warranty, and support policies. Our primary focus here is going to be on how the 2707WFP compares to both the slightly larger and slightly smaller offerings on the market.
One of the factors that many people are going to be interested in is the pixel pitch of the various LCD offerings. We've compiled a list of typical pixel pitch sizes for a variety of LCD panels and resolutions. Some people feel a smaller pixel pitch is always more desirable, and while that might be true for some uses, reading text on an extremely fine pixel pitch can at times be difficult for some of us. If you've used a 15" laptop with a 1920x1200 resolution, you will hopefully understand. We know plenty of other users that find the typical 17" LCDs are not comfortable to use at the native 1280x1024 resolution, which is why many people prefer 19" LCDs. (Modifying the DPI setting of Windows can help in some areas, but there are quirks to changing the DPI from the default 96dpi setting.)
As you can see from the above table, the 27" LCDs currently boast the largest pixel pitch outside of HDTV offerings. However, the difference between a 15" or 19" pixel pitch and that of the 2707WFP is really quite small. If you're one of those that feel a slightly larger pixel pitch is preferable - for whatever reason - the 2707WFP doesn't disappoint. Dell has made some other changes relative to their other current LCD offerings, however, so let's take a closer look at this latest entrant into the crowded LCD market.

And here I preferred aperture grille over invar shadow mask in the CRT days. Again, it was the colors and overall brightness. Most CRTs look "fuzzy" to me, and I like the sharpness of LCDs. You look at black text on a white background and you can clearly see that every pixel is a direct mapping of the digital information. CRTs, you can get artifacts due to stretch and centering, not to mention rotation and pincushion... that stuff always irritated me. So yeah, I really do prefer LCDs.As for the "bright top and darker bottom", I don't notice that at all, even on 30" displays. It's probably there to a certain extent, but it's nowhere near as bad as any of the older TN+film panels (which are still common on notebooks). Turn down the brightness to a more moderate level, and everything is great for me. I truly do prefer the image quality on my 30" (or 24") LCD over any CRT I've used.
The final issue is that many (most? all?) developers are now using LCDs as well. I remember thinking Doom 3 was way too dark to the point of being almost unplayable. Then I got my LCD (a 2405FPW at the time) and suddenly the whole game changed. It still had flaws, but darkness was no longer one of them. I think id must have been using LCDs, so they never realized what the game would look like on a typical CRT. (Of course some CRTs are brighter than others; mine was not one of those.)
I can understand that some still prefer CRTs, but I'm definitely not one of them. Given the choice, I would always take a good LCD over a good CRT these days. I just hope stuff like OLED and some of the other technologies in development can make it out sooner rather than later. Give us a nice 120 Hz refresh rate with a bit faster response times, and I'd be very happy indeed.

Jarrod,Even with the brightness turned down all the way, I found the LCD gave me headaches. That's why it became one with the air, and then the ground. I couldn't get used to it. I think people's vision has a lot to do with it. I remember when IBM came out with the 8514/A and we got them, I raised Hell because I got headaches from it (it was interlaced). They thought I was whining, but I could see the flicker really vividly and it gave me the worst headaches (incidentally, I just bought one on eBay for $5 :P). The LCDs are not only too bright, even turned down all the way, but it's like looking through a screen door at a picture, because I can see very easily the boundaries between pixels. It's not as smooth or rich as a CRT.
I don't play shoot 'em ups anymore, they bore me terribly. I prefer the strategy games, and even games like Civilization. I guess LCDs have become necessary for shoot em ups now, although it's kind of funny because they are so poor at it because of the slow response time. But, they have to develop to what people have, and LCDs are definitely more common. Why they are so bright is a mystery to me though. Maybe because they are so poor with respect to viewing angles and saturation, they try to make them extra bright to compensate.
I can see the differences in brightness so easily in LCDs it is surprising you don't have a problem with it. I think some of it is what you are used to. If I had these for years, my eyes would adjust to it and I would really see it. Remember the first time you saw a flat screen CRT? It seemed screwed up because your brain had adjusted to the curved screens. A lot of stuff we adapt to without even knowing it. Again, I do think we all see differently, and it's not just a matter of opinion. It's got a lot to do with how we actually see it. I know with respect to refresh rates it is, because I'd ask people to look at stuff, and they didn't see the flicker (normally it's easier from the corner of your eyes, probably our adaptation to seeing movement in peripheral vision well so we could see things sneaking up on us?).
The thing about CRTs I can't stand are the moire problems. CRTs seem to be extremely accurate in most dimensions at 800 x 600, but when you start getting higher there seems to be more distortion. And the size and weight. Ugggh. The mainstream CRTs are pretty foul too, but luckily I loaded up on the Eizos and they are much, much better than the Viewsonic, Sony, Dell, etc... rubbish. I was considering buying an Eizo LCD, but I don't know if all LCDs suck bad, or it's just the mainstream rubbish again. Eizo has a way of changing the rules, at least they did on CRTs. That's why I'd love to see a review on them, because at this point they are the only ones I'd consider. I guess I could put it on a server if I didn't like it, so I don't have to look at it for long. But, they are so expensive, I'm a little concerned I'd be throwing good money at bad, because the technology is so weak even they can't get it to work. Dell, et al, obviously aren't going to put out a very good product since the cost would preclude them selling enough. But Nanao, well, they might. Any chance of you reviewing one?

I can ask them and see if they're interested in sending one for testing. Honestly, though, I'm not sure my review would be of any use to you. I'm already happy with current LCDs, and you're not. This is one of those cases where you might need to see about testing one in person to see if the results are acceptable or not.I've always had a problem with low refresh rates on CRTs as well - anything less than 85 Hz I could detect a flicker, and while 75 Hz was tolerable the 60 Hz displays gave me headaches. That's one of the things I like on LCDs. The backlights are always on, and rather than having a beam scanning across the monitor at 60 Hz, the light is evenly distributed and there's no chance for a pixel to start to darken and then light up again.
I do know what you mean about adapting, though. The first time I used a 30" LCD I was like, "WTF!? It's too big!" Now I'm quite happy with the size and it no longer bothers me at all. When I go back to a 24" it seems small, relatively speaking. Heh.

Jarrod,It might be helpful. I want to like LCDs, mainly because of the footprint and power/heat issues with CRTs. But, I couldn't stand the one I had. I might have gotten used to the flaws and then hated the CRT flaws, but the brightness was such I got really painful headaches and couldn't spend the time on it to adjust to it.
So, if you get an Eizo and your review says it's much better than existing LCDs, it would at least be useful. On the other hand, if you say it's nice but pretty much the same, well, I'd probably pass and wait another couple of years before looking at one. Also, I think it would be very, very interesting for your readers, and probably even for you, to have an absolutely top quality display to review. It would be informative, because I think a lot of people don't even know they exist and think these mainstream brands offer the best displays. Who knows, maybe they do, and a review might point that out. If they are willing to send you one, and I'd have to think they are crazy if they don't (because they need the visibility since they are very poorly known), I think it would be a really interesting review for all those reasons, and not just to me.

Have you tried looking at a good LCD in a store? Most of the commonly available ones are cheap and not very good - they show the contrast gradient top-to-bottom you referred to. IIRC the review of the HP said they accept them back for pretty much any reason within the return period, so you could toss it back in the box instead of out a window if you don't like it. Just be sure to get a decent one, not a cheapie.I too would be interested in seeing the results of a test on an Eizo or an NEC W-series. I'd like to see how the calibration results of what are pretty much considered the top professional diplays look like compared to the mainstream/gaming displays.

Having purchased the 2407WFP in mid-November at under $600 (not including the tax and the price for extending out the warranty to 5 years), the price on the 27" seems kind of steep. Maybe if Dell had upped the ante by adding HDMI, or a second set of component ins, it would put it over the top.I'm also a little disappointed that their card readers don't support xD Picture Card format, which is what my Fuji FinePix camera uses. Minor nitpick, but one that shouldn't be all that hard to fix.

the gateway spec at 125watts and this is 95wtt..that's an efficient build for a 27in lcd.JarredWalton - Wednesday, April 4, 2007 - link
The Gateway lists 125W maximum I think, so typical power use is probably less. The 95W for the 2707WFP is after calibration (i.e. with lowered brightness levels).anandtech02148 - Wednesday, April 4, 2007 - link
is it exciting to review all these new fresh monitor? or do you get sored eye after all the calibration work.Again thanks for the calibrated file you upload.

Speaking of which, if anyone is interested, here are the http://images.anandtech.com/reviews/monitor/2007/d... 2707WFP Profiles.rar">2707WFP profiles used in this article. Standard "your LCD is not the same as the tested LCD" disclaimer applies.As for sore eyes, no, that's not a problem. The calibration isn't all that difficult to perform in most cases. It's the writing, graph generation, and photo editing that takes the most effort.
