Dell UltraSharp 1905FP: Setting the Bar for New 19" LCDs

Construction (continued)
In fact, the only major change that occurred to the aesthetics of the monitor is on the height adjustment stand. The stand looks very similar to the original one, but it looks like Dell ditched the rounded design for a slightly different structure. The universal joint on the back actually pivots much easier than the one on our 2001FP, a plus for the 1905FP thus far.

Dell completely redesigned the cable management in the rear, but in our opinion, plastic housing isn't much of an improvement over the previous attempt (which we didn't find very useful either). The monitor still features a quick release for a VESA wall mount. You can also see a button that activates the vertical height adjustment in the picture above.

From the inputs above, you can see that Dell ditched the brick power supply. The 1905FP houses the AC to DC inverter inside the rear panel and hooks up using a standard three-prong 120V AC cable. For comparison, we included a snapshot of the Dell 2001FP input set below.

After a few hours of operation, we recorded the air temperature near the exhausts of the LCD around 28 degrees Celsius with an ambient air temperature of 23 degrees Celsius. This is several degrees cooler than some of the other monitors that we have in the lab, like the Dell 2001FP and NuTech L921G.
Bleeding Light
Several of our forum members are fairly upset about UltraSharp 2005FPW models that have intermittent backlight problems. With this subject in mind, we paid extra attention to backlight issues in case there might be problems on the 1905FP as well. While we did not detect any problems on our panel (screen uniformity was perfect), we did notice that we could actually see the backlights from outside the monitor!

In the image above, you can see the light of the backlights reflecting off something metal. We could not detect the light without looking carefully into the monitor. The obvious problem here is that the electrical components and backlights are exposed to the elements - even if that might be an office environment. If dust settles on the backlights, we could have a big problem with screen uniformity and brightness. Remember the Samsung 193P that uses the same panel? When we tested that LCD, we thought it was innovative that the monitor completely enclosed the LCD panel without any openings. In retrospect, Samsung's decision to do that might have been more function than form.
Opening it Up
After benchmarking this monitor, we opened it up to get a more in-depth look at the individual apparatus. Doing this will certainly void your warranty.
Separating the electronic components from the panel, we can see the underside of the digital/analog PCB on the left and the power inverters on the right. The entire electrical packaging behind the panel is less than an inch thick, which is impressive considering that inverters typically take up bulkier packaging - we refer to power bricks as "bricks" for a reason. We have always applauded integrated inverters in LCDs because they are more efficient. When we have external inverters leading to the monitor, the DC must be modulated and inverted back to AC for the florescent backlights.

wow, a "that car looks nice, i dont care howmany horsepowers it has, no dont tell me how much gas it takes, so what i maybe can only drive it backwards, it doesn Look that bad" kind of guy :)gg hf :P

Have you guys looked at newegg? There are a ton of 19" LCD's under 350 - I just picked up one with DVI and 21ms response time 600:1 contrast for $320 - no rebates or anything. I have never heard of CVM, but the monitor looks very nice, IMHO.Later,

Does anyone know if the Dell UltraSharp 1705FPT is also a Samsung panel and/or an 8-bit panel?I've asked the folks at Dell this 6 times over the past two weeks. They have no idea. It's been a very frustrating experience for me. Maybe I'm asking the question wrong, but you would think "Is the Dell UltraSharp 1705FPT an 8-bit or 6-bit panel?" is pretty clear enough.
Supposedly it's a 13ms response time monitor, so I'm betting it's 6-bit. I just can't seem to find a 17" 8-bit panel with a response time less than 25ms.....
Sorry if you've already read this question on the "General Hardware" forum.

The comments below were stolen from another Anandtech member Sharkeeper :)I find a good test is go here.

Accept any security messages you get. When the applet loads, maximise the window. It should look like this. Use your mouse to move the position of the globe. All those white pixels are indicating where satellites are in real time. If you orient the orbit lines parallel to the Y axis (up and down) and drag the mouse around you will perform a very good test on pixel update rate. Slower monitors will cause the satellites to disappear in the background as the scene is moved. Faster monitors will show them available at all times.
Nessism comments:
When moving the satellites on my 1905, they change from being a dot to being a small moving line (ghosting image of the dot). I'm not trying to bash this monitor, after all I do own one, just want to make people understand that there are limitations.
Good test.

I have a 1905 and can assure everyone that it DOES ghost when moving quickly. As stated, everyone has a different sensitivity level...just don't expect this thing to perform like a CRT for fast motion because it does not. If you want a true gamming monitor, check out one of the fast TN monitors like the new Hyundai; they give up viewing angles and color but they are fast.Fast with small viewing angles (TN) or slightly slower with better color and viewing angles (PVA). Take your pick, you can't have both.

Looks like a great deal but I can relate: having a "dell" logo on something I own is just not kosher. :) Good thing I'm not in the market for an LCD.My viewsonic vp181s has a usb hub, I didn't think it was that rare.
Call me bass ackwards, but I think 1280*1024 is just right for 19". Okay my panel is 18.1" but I would like to be able to sit a few inches father away and still read standard-sized text. On a notebook you're going to be sitting closer, so a little more resolution is okay, but those microscopic ones with 12" screens and huge resolutions are over the top. Most people I've seen turn the res down, which is a shame b/c then you're wasting the screen's potential.
Regarding the aspect issue, yes 1280*1024 is a little "squished," there's more vertical pixels. 1280*960 would be the "usual" 4:3 aspect ratio. To anyone thinking this is a drawback, honestly you don't notice that everything's a little shorter, I've been working at that res for some time.

Hello all,Some words to all the crt-to-lcd gamers out there, buzzled with anandtech guys politicaly correct statements about gaming on it:D
I happen to have Samsung 193P, so it's pretty much the same panel and so on.
long story short:
1. If you play stuff like mmo's and rts games, you will have no problems, and all gain from picture quality + less strain on eyes (than crt)
2. If you play stuff like CSS, UT2k4, BF1942, you will have serious ghosting. Dunno how come they dont see or recognize it. So shooting stuff wile running AND turning, is not simple, you must stop moving to aim properly.
I offer very simple way to see it, for Anandtech guys too, just fire up bf1942 and move the view left/right fast, with mouse, edges of buildings and vehicles etc jump over the screen, not like OMG wtfbbq is that wall doing here, but its indeed "ghosting", it doesnt exacly get in a way but it disturb seeing clearly and fast, while moving whole picture.
ps. I cant figure out how to set backlight temperature on my 193p, there is no temperature option in the soft, brightness isnt temperature.. can anyone help me find it? thnx in advance
