Windows 7 on Latitude E6400

Thanks for letting me know. I will probably, go with DVI picture and DVI sound then.

 

huh?

Ok, let me explain.

You have different communication standards to allow to attach a monitor (TV, computer screen, etc.) from a computer/device (device examples: DVD player, Blu-ray player, XBox 360, etc.)

The popular ones are:
- component: 3x RCA type cable where all 3 needs to be connected to get a proper image. ONLY image is pass trough that wire. Each wire are of color Red, Blue, Green.


- composite: 1x RCA type cable, which transfer an analogue signal ONLY. To transfer the left and right audio channels, 2 additional (1 per channel/speakers) RCA type cables are added. All 3 cables are transiting an analogue signal. They are usually identified by 3 wire of color yellow (for the video signal), red (right speaker), and white (left speaker)

Very popular cable back in the good old days.

- VGA: An analogue plug reserved for the PC market, which promotes image sharpness, high resolution, and color accuracy compared to composite cable. ONLY video image is sent, no sound. It's purpose was to send a high fidelity image to an analogue type monitors, such as a CRT monitor (the screens with the large tube in it, that we used to use before LCD)


- DVI: A digital plug mostly reserved for the PC market, which send a digital image signal (and ONLY image) in a digital manner for digital monitors, such as LCD screens (the thin screen that is all the craze, today)


- HDMI: A digital plug mostly reserved for the home theater market, which transmits digitally BOTH image AND sound into one cable.

- Display Port (DP, for short): Display Port is mostly reserved for the PC market. They are different versions of DP.. the early version was image only, and the later one, IMAGE AND SOUND. Your laptop has the latest DP version. So, sound and image is transmitted, just like HDMI. Today, Display Port is identical in characteristic to HDMI, at 98-99%. Hence, why a simple adapter can be used. Unlike HDMI, Display port has a better plug which holds better in place, thanks to a clip system, and requires no royalty fees to pay, so cheaper to have in a computer/device, and cheaper cables.
Future of Display port (version 1.2) is interesting: It will support daisy-chaining up to 4 monitors from 1 plug on the system (so 1 plug can provide an different image per monitor for up 4 of them (so it's LIKE 4 DVI cables in 1)) - 1920 x 1200 max per display, or 2560 x 1600 max for 2 monitors, and 3840 x 2400 for 1 monitor. In addition, it will support 120fps-per-channel 3D support for all 3 monitors, AND a 21.6Gbps data rate AND bidirectional USB data at up to 720Mbps. This means, DisplayPort 1.2 cable can work like ultra fast USB hubs powering integrated or external webcams attached to the monitor, memory keys, and external USB drive .


In other words, it massacre HDMI. Dell is a strong supporter of Display Port.

 

last request. now that NEITHER forum is active, can we please close this and move to just the owner's lounge? it wouldn't be interrupting ANY on-going threads.

 

Hi all,

I have connected EIZO S2233 equiped with DisplayPort to DisplayPort on E6400 with standard M-M DisplayPort cable.

However, Eizo will not detect signal on DisplayPort input, VGA works as usually, at least.

Also, NVIDIA NVS 160M drivers does not detect external display at all.
The same on Windows XP SP3 and Windows 7.

I have NVIDIA drivers and BIOS updated (01/2010) and also Windows 7 is patched to latest level.

I wonder if DisplayPort on E6400 is working actually.

Can anybody confirm that DisplayPort->DisplayPort works with EIZO monitors equiped with DisplayPort via DisplayPort cable ?

Thanks in advance,
Peter.

 

Display port on the Latitude E6400 works perfectly. I use it with my Dell U2410 monitor.

Try the latest GPU drivers from Nvidia website:
http://www.nvidia.com/object/notebook_winvista_win7_x64_195.62_whql.html
Make sure to uninstall the old drivers first, followed by a computer restart, then install the latest ones, and restart once more when done.

Some additional information:
Once you plug your display, do Win + P key combination, this will pop-up Windows external display/project switch panel. From there you can select which mode you want (you can do Win+P several times to pass through each time or click on one with the mouse).
- Main monitor only (laptop screen/secondary screen if the laptop lid is closed)

- Duplicate the image and resolution to the external source (if the external display/projector is slower than the laptop screen, then the laptop screen will lower it's resolution so that both screen show a full screen image.

- Extend the workspace to other displays, this basically makes your desktop larger (spread out on 2 screen), so that you can have more space to work.

- Project only. Output on the external screen/projector only no mater if the laptop lid is open or closed.

 

Thanks for confirmation.
It is resolved now.. other DisplayPort cable works for me now.. so I am happy again.

Only small issue is that Windows 7 does not detect native 1680x1050 on my Eizo S2233 on DisplayPort (on VGA it detects correctly).
I am searching for some *.inf driver or something similar...

Peter.

 

No driver hack needed. 1680x1050 is just not a standard resolution for computer screen (16:9 not 16:10). All you have to do, is go to the Control Panel, and open the Nvidia Control Panel. From there look into of the sections to add a new custom resolution. Now Create a new resolution of 1680x1050 @ 60Hz. Now select that resolution, set it, and VOILA!

 

Hi,

Actually Eizo S2233 with native 1680x1050 is 16:10 ( 1680 / 1050 = 1.6 ).

Absolutely first thing I did was to create custom resolution via control Panel with 1680x1050 @ 60Hz and even 20 more attempts with frequency and other fancy options changed. No luck

What I have googled is , that it is possible that graphic chipset may not support even 1680x1050 on DisplayPort output (vga works), even if it is very common standard in these days.

I have updated Quadro NVS 160M and Windows 7 drivers, also Eizo S2233 inf file is installed and detected correctly.

Please, can somebody confirm that E6400 with graphic chipset NVIDIA Quadro NVS 160M supports on DisplayPort external monitor resolution 1680x1050 ?

Thanks in advance,

Peter.

 

It runs on 1920x1200 on mine so i think 1680x1050 shouldn't be a problem. It shouldn't be necessary to set up a custom profile either, just set it up to run dual monitors and then you set the right res. for each.

 

Thanks for info, seems there is dependency on OS (I am using Win7 32bit while yours run 64bit). Also I have EIZO S2233 and other types may work better.

I have checked release notes for latest Nvidia driver and they claim to correct Loss of Video when external monitor connected via Display port... seems this fix is not valid for me

I will switch to VGA cable, but this is something I did not expect when buying EIZO and Dell stuff
