Ummagumma said:I have seen no definite answer to this anywhere yet Have anyone tried with both the vga and the components and gotten the same sharpness in the picture?
Great news guys. As I was saying ealier in the week, Dell say it's capable of it, but they won't support the issue. E.G If you break it, we never said it would work.
My 2405FPW doesn't even support it unofficially. http://www.hardforum.com/showpost.php?p=1028649958&postcount=104magnetik said:according to this quote at wsgf by maherie (who works at dell), I would assume that it does support HD but not "officially"

http://www.widescreengamingforum.com/forum/viewtopic.php?t=2111I just hooked it up to my 42" Plasma ... which I didn't realise was HD ... ... and it looks fantastic ! ...
So any ideas as to why it's not looking so good on my dell 24" ?
asmielia said:I haven't run that test, but I can assure you that the 2405 supports HD over component. I'm using it right now as my HDTV using an HD set top box. It's a night and day difference over SD at 1080i or 720p. I can pretty much guarantee it's not upscaled. The OSD confirms what I'm seeing on screen as other people have pointed out.

Ummagumma said:1. Does Johns pictures look like the 2405fpw support HD through components?
Ummagumma said:2. Is the OSD showing the input of the 2405fpw or the output?
Ummagumma said:3. When it comes to movies and tv, does the quality of the source matter when it comes to the output of the screen?
Ummagumma said:4. If you downscale HD material to SD resolution, would it a) look the same or b) be sharper or c) be less sharp?
Ummagumma said:5. Do the channels broadcast the same quality of the SD resolutions as the HD resolutions (besides the difference in resolution)? Compression quality, signal strenght, is one digital and one analog?, framerate etc...
Ummagumma said:6. Does DVD`s look the same as broadcasts of the same resolutions if source doesn't matter?
Ummagumma said:Maybe there are different revisions with different electronics out there or maybe the xbox 360(and also the PS2 from what I have read) isn't quite compatible with the 2405fpw?
When I switch the scaling mode to 1:1 I get the same thing, with the correct image size being shown. Nevertheless, the image quality remains the same - it's just bigger.asmielia said:Anyway, I'm 100% certain that this monitor supports 720p and 1080i. I'll try and get some pictures up, but it might be hard to show.

Let's say you have a games console that produces a flawless image on 99% of high definition displays, and a poor image on the other 1%. Are you suggesting that the flaw lies with the console, rather than the 1% of HD displays that produce a poor quality image? An interesting approach, although I don't understand the logic behind it.asmielia said:I couldn't have said it better myself magnetik. John, I understand you wanting to get to the bottom of your 360 issue, but trust us on this one: The 2405 is fully HD capable.
Great news guys. As I was saying ealier in the week, Dell say it's capable of it,
but they won't support the issue. E.G If you break it, we never said it would work.
The gm1601 display controller is a fully integrated, single chip solution for
multifunction LCD monitors supporting resolutions up to Wide UXGA (1920 x 1200) and
HDTV video up to 1920 x 1080. It features motion adaptive deinterlacing and low angle
directional interpolation for high-quality TV playback.
For an optimized display, particularly of rapidly moving images, top-of-the-line
technology is used with Adaptive Motion Deinterlacing from Faroudja, who have many
years of experience with high-end flat panel televisions in the consumer market. The
CRTtoLCD-7 allows the input and display of resolutions up to WUXGA, thanks to the
Genesis gm1601 chips. Thus, it also includes HDTV resolutions (e.g. 1080i = 1920 x
1080 or 720p = 1280 x720); HDTV is expected to become very significant in the market
by the time of the 2006 World Cup.
Samsung Electronics Co. Ltd., a global leader in the consumer electronics
industry and world's largest provider of display panels, selected the combination of
Genesis Microchip's gm1601 display controller and FLI2310 video format converter for its
new 46-inch and 57-inch LCD TVs. The 46-inch LCD TV, model LTP468W and the 57-inch
LCD TV.
Both the 46-inch and 57-inch TFT LCD TVs offer a 1920 x 1080 resolution and feature
HDTV functionality: 1080p, 720p and 1080i. The 57-inch LTP57W features 600cd/m2
brightness, a maximum 8ms response time and utilizes Samsung's vertical alignment and
advanced polarization technologies to achieve a 1000:1 contrast ratio.
Also, while the game supports both 480p and even 1080i resolution, its
implementation does not prevent a few jaggies or blurring effects from appearing during
replays.

The genesis comes in standard (non-HDCP) and a HDCP. The 2405fpw uses the standard version.
As you can see from the gm1601 system diagram, the analog RGB (VGA) and the DVI connects directly into the genesis, while HDTV/SDTV, Video, RF needs additional chips (ADC, decoder and tuner). The other chips are integrated on the video controller board like shown here: link
Now, the main question is: did Dell cheap out on the components input and chose a video controller that don`t support HD through the components (only PAL/NTSC/SECAM) to lower costs like shown here:
HOW DOES THE DVD-HD931 WORK?
Samsung DVD-HD931 operates based on digital processing. In order to display a high-quality picture, it performs video processing, including Video Format Conversion using FLI2310 chip by Faroudja Lab. technology, Samsungs DNIe Chip, and DVI technology that supports Digital Image Perfection.
Video Format Converter
A normal DVD player transmits a video signal to 480i output when playing a DVD Title (480i/480p). Even with a progressive scanning DVD player, it simply outputs a video signal of 480i-to-480p. However, Samsung DVDHD931 enables you to enjoy an HDTV compliant picture with an ordinary DVD Title, thanks to its scale-up to 720p/1080i.
Video Enhancement
Samsung DVD-HD931 exhibits a remarkable enhancement in picture quality by adopting DNIe (Digital Natural Image Engine) chip, Samsungs unique digital processing chip.
DNIe Chip
: It is located between the FLI2310 chip and DVI circuitry. It receives the digital video output signal processed by FLI2310, corrects for picture quality, and then outputs a digital video to DVI.
When it comes to the HDtv pictures, I think I'd have to take your word on that one. I just compared to a file I have from HDTV on my computer that has been downscaled to 624x352 and actually looked better. I don't think your pictures do justice either. It depends so much upon signal source too and thats the beauty with the xbox, since it the display source is "fixed".
about components inputIn order to sell TV sets in the DVD age, a component input must be provided. It is often accomplished by converting the incoming component signal to S-Video, then sending that signal to their standard decoder chip. Believe it or not, this is a common practice, not only among TV set manufacturers, but in several video up converters.

googleli said:I don't know much about all these chip things, but if you have an XBOX360, just hook it up with component of 2405FPW, and then switch between 480p 720p and 1080i, with the "aspect" option so you can compare them at the same size without distorting the image. You don't even need to actually play a game. You will notice the difference just by looking at the menu. I think that would explain everything to people with normal eyes.
magoo said:all I know is this......I dial in 1080i on the 360 dashboard....
run the component plugs to the Dell 2405......
the picture that I get is superb. Ive played PGR3, kameo,PDZ, and Halo2 and to tell you the truth am not bothered by jaggies, distortion or any other video anomalies.
The picture just plain looks good, crisp and clean.
Paddy the WakThe plasma looks way better than the Dell in reality ... the image is smoother ... there are way way less jaggies and overall it just looks more photo-realistic to me.
Ummagumma said:Secondly, Dell doesn't support HD components on the 2405fpw.
googleli said:Regarding Jaggies - if you compare Dell with most LCD TVs (which have resolutions lower or much lower than Full HD), Dell will have MORE JAGGIES. The difference is like playing PS2 on a monitor vs playing on a conventional CRT tv. The image on the conventional low res CRT will have MUCH FEWER JAGGIES than you would believe. Ridge Racer 6 does display whole lotta jaggies when compared with my Plasma, because my Plasma has MUCH LOWER RESOLUTION at 1024X1024. But when I try Dead or Alive 4, where Ninja Team has clearly worked on the Jaggie issue, it looks razor sharp on my Dell and the image quality is much better than on my Plasma due to the resolution difference. Or, if playing a game is too difficult for your eyes to tell, you can try just looking at the Xbox360 menu. Don't believe the friggin photos. Borrow an Xbox360 to hook it up and you will see.
