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

Quantitative Analysis
For the duration of this review, we connected the UltraSharp 1905FP to a Radeon X800 Pro with factory default settings on the DVI connection unless stated otherwise. Brightness has been set to maximum as well.
Luminance
Brightness ranked as one of our most important display qualities. The largest mistake that we see people make when they buy a new LCD is to put their new, bright LCD in a dim/dark room (and then turn the LCD down to 25% brightness). Not only is this terrible for your eyes, but it also unnecessarily offsets hues; a blue screen in a dark room doesn't look the same as a blue screen in a well lit one! Staring at your monitor shouldn't feel like staring into the sun. If you have plenty of ambient light around, you would be surprised by how much different a 250 nit LCD looks compared to a 300 nit LCD.
Below, you can see a comparison of the brightness for each of our LCD monitors.
The 1905FP sits right in the middle of the pack for brightness.
Our Contrast Ratio
We will the same observation from the 19" LCD Roundup two months ago. Using PreCal and our ColorVision Spyder, we will measure the luminance of a pure white image and a pure black image on the LCD monitor. The observed contrast ratio is simply the highest recorded luminance divided by the lowest. All measurements are in candela per meter squared; larger contrast ratios are more desirable.
| Observed Contrast Ratio | |||
| Highest Recorded (white image) |
Lowest Recorded (black image) |
Observed Contrast Ratio | |
| BenQ FP931 | 256.4 | 3.6 | 71.2 |
| Dell 1905FP | 234.6 | 2.6 | 90.2 |
| NuTech L921G | 278.2 | 2.6 | 107.0 |
| Planar PE191M | 234.0 | 3.0 | 78.0 |
| Samsung 193P | 230.4 | 2.2 | 104.7 |
| Samsung 910V | 219.8 | 2.6 | 84.5 |
| Sony SDM S94 | 233.8 | 3.0 | 77.9 |
| ViewSonic Q190MB | 261.8 | 2.6 | 100.7 |
The Dell 1905FP emits a brighter image than the Samsung 193P, but at the same time, it also has a slightly higher darkest dark. Even though the Samsung 193P and Dell 1905FP are using the same panels, Dell may be giving the backlights a little bit of a boost in power to increase brightness. Both LCDs appear in the middle of the pack for contrast ratio.

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
