LP240zx Display Port Problem
Aug 23, 2009
I have very unusual problem. New HPZ800 quad core with QuadroCX video card running Windows 7 64bit release candidate. 6 mb Ram. Remarkable performance.
Bought dreamcolor HP Monitor. Ran fine. Latest firware. Newest Nvidia drivers. Newest monitor drivers. Calibrated fine with Spider Elite colorimeter. Profile appears very good.
One hour later goes into screen saver mode or something. Black screen using Display port. Use display port adapter to DVI cable works fine. This appears to exclude bad display port output from card.
This is the second monitor that does this. The first was reported as monitor defect.
Anyone had this experience or suggestion?

I have been having troubles with my display port monitor, and I just realized that the monitor is picking up 1923x1080 60hz (thats what the HP settings say on the monitor) but according to Windows its sending out 1920x1080. ATI Radeon 5770, I don't have CCC installed because of previous issues, any ideas why I'm getting such an odd resolution?

I am getting a lot of BSOD when my laptop is connected to an external monitor using a display-port cable.The system is fine when I don't use a external monitor and use just laptop screen. External monitor is a Dell 30inch. I have tried different display-port cables, different monitors, tried connecting via vga...still get BSOD, so I am thinking the problem is more on the windows 7/software side rather than hardware.
1. Uninstall AVG free edition 2011
2. Upgraded network-gigabit driver directly from intel instead of Lenovo
3a. Upgraded Nvidia drivers directly from nvidia for Quadro 1000m (ver 8.17.12.7533 - 5/20/2011) - got BSOD within 30min
3b. Downgraded Nvidia drivers to version from Lenovo (ver 8.17.12.6696 - 2/2/2011) - still get BSOD but there is more time between BSODs.
I am using a lenovo w520 laptop, win 7 SP1, x64. 8gb memory, intel 510 solid-state drive, Nvidia Quadro 1000 and Intel HD Graphics 3000, No-Anti-Virus and running zone-alarm firewall.

I have an xfx radeon hd 6790. I am using the hdmi port and the display port for two tvs and I am using the vga (I think its called the vga) port it sez right on the box that it supports 3 monitors. I can switch between any two that I want but I cant get all three to work at the same time. I try to use all three at the same time I get "to extend the display another display must be disabled".

I'm trying to connect my PC to my TV. I'm using the display port on my Lenovo thinkpad, and using a converter to connect an HDMI cord from my computer display port to my TV. However, when connecting, I get an image on my TV screen for several seconds, then I get the message "not supported mode."I've got into my control panel and adjusted the screen resolution, setting the TV resolution to highest (1920 x 1080). The computer screen is set at a refresh rate of 60hz, but the only option I have for the TV is 30hz, interlaced.Lastly, I have three hdmi ports on the TV. The closest I've gotten to getting this to work is plugging the HDMI cord into port 3, which is set as "game" on the TV settings.
Does anyone have any further recommendations on how I can get this to work? When the image shows for 5 seconds on the first port, it's very clear, but then goes to "Not Supported Mode". The third port shows the image, but is very fuzzy with lines shaking across the screen, so clearly, neither of these options are currently working.

the display/monitor uses the generic driver for display and it is 1024×768 or 800x600 but it looks very odd it should be bigger because my screen is bigger. I have a acer monitor but is there something I can download to fix the display size?

Windows 7 64 turns off the monitor 1 signal after startup. At login, it powers off monitor 1 and powers on monitor 2. Windows 7 behaves as though dual display is working even though monitor 1 does not display. It's the same for single display, the monitor will not work on cable 1 except at startup.Both 'Extend these displays' in Windows Screen Resolution and 'Extend' in the Nvidia Control Panel is selected. And changing which one is primary does not turn on monitor 1. Nor does switching the position of display 1 in either (ex.left/right/top/bottom).GeForce 8400 GS; Dual Monitor Solution 59 pin (DMS-59) to 2 VGA adapter -tried two of these adapter cables.atest Driver: 306.23 - installed a clean reset install of the latest Nvidia driver released last week.Same Resolution: 2 of the 4 monitors I have tried have the exact same 'recommended' resolution (1280X 1024), both 60Hz, and even chose 16 bit color for both instead of 32 to reduce resources.
Linux worked: Dual display worked immediately when I tried it in Ubuntu 10. So, it's not the hardware. It works in Ubuntu 12 too but not properly -it won't transfer windows across displays. My Windows 7 64 is an upgrade from Vista 64. One person in another forum with the same problem resolved theirs by reinstalling Windows 7. But another got the same problem only after a fresh clean install of Windows 7 64 with the same GeForce 8400 GS and DMS-59 when it had previously worked in Vista.

Last night my new laptop arrived (XPS), still getting used to windows 7 etc... but i thought i would watch something through my t.v. Plugged HDMI cable in back of laptop straight in to t.v, changed the source and straight away i had a lovely sharpe picture of my deskop instantly.... or so i thought
im getting the middle part of my screen fine - but it is cropped so i cant see the tool bar (its too low) and the desktop icons are only veiwable if i move them closer in screen! Ideally i want to have identical screens on both so i can use both at sam time, but currently i can only view either or atm? and the t.v one being crop means i can use it as a computer (No toolbar etc..)
I could figure this out on XP but windows 7 seems beyond me atm!

To all the computer geniuses out there, I guess this isn't a windows 7 problem but it's about drivers.I have an Asus K53E-B1 with Windows 7 64bit. It comes with 3 USB 2.0 ports and that's it. I went on the Asus website today and found USB 3.0 drivers update.I can't just download those drivers and use them and expect USB 3.0 performance when I have USB 2.0 ports right?

I just installed Windows 7 and updated all my drivers. I am missing two drivers, and I don't know what they are:
PCI Serial Port
PCI Simple Communication Controller
What exactly are these? I own a Lenovo X200 Tablet. Any ideas where I can find the drivers for these two things?

I have a quick question about the USB ports on my computer. I have a screenshot hosted here on Flikr: USB | Flickr - Photo Sharing! Of the 5 USB's that are listed, one is a USB2. Is the USB2 Enhanced Host Controller a USB2.0 port? I am looking because I am going to buy an audio interface and if I have a 2.0 in there then I will get something a little better 'cos I want as little latency as possible when recording vocals.
There is one other thing also, if it turns out that there is a 2.0 port, is there a way to physically differentiate which port is the 2.0? I have 3 USB's on the back and 2 on the front of my tower. At the moment I don't know which is which and do not know what to physically look for when I look in or out of the case.

I have an application to control external devices via IRDA.The application only accepts IRDA connected via a serial port.I only have a USB-IRDA device.
Is there any freeware driver/software to create a virtual serial port and link it with the USB device?

New PC has a 1394 Port.
Familiar with the USB Ports of course, but have never used a 1394 Port.
What and where is it used ?
For what ?
What devices should utilize it ?
And whatever else I'm not sharp enough to know to ask about these Ports, please ?

I use my computer aboard a 47' Sailboat primarily for navigation and communications. As such, I run multiple external devices. To name a few:
WiFi Cards (2)
GPS
Pactor Modem
Iridium Satellite Phone
Verizon Aircard
Telcel Aircard
You get the picture. I was unable to accomplish a very simple task using VISTA, to wit, being online with my Verizon Aircard and using one of the WiFi cards to access my wireless printer.
I finally downgraded to Windows XP and this is never a problem anymore. A Verizon tech once gave me an explanation of why this couldn't be done in VISTA, but unfortunately the explanation went over my head.
Does anyone know if this problem has been fixed in Windows 7, or does that OS have similar problems as VISTA handling multiple communications devices operating simultaneously on different USB ports?

I have spent the last two hours trying to open a port for a remote control application.
I have tomato 1.27 running on an asus wl500gP router.
I am running windows 7 ultimate
i have an Arris voip modem through comcast
The problem is this, i forwarded the port correctly in tomato yet the port is still closed. I have tried the following:
Enabling DMZ
Disabling windows firewall by either the control panel or through services.msc
Enabled UPNP in the application, it opens the port according to tomato yet external port testers still say its closed
reset the router and pc numerous times
hard reset the router
Hooking PC directly into cable modem
I believe that this is strictly a windows 7 issue now as the router is out of the equation. The only security software I have is Avira free edition, windows defender, and (disabled) windows firewall.
Can anyone give me help as to why I cannot open a port? It would be greatly appreciated as I am leaving for a trip in 36 hours and would like to be able to remotely control this application.

I tried to change the default remote desktop port from 3389 to some other 4 digit number.
I did this via regedit
HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Terminal Server WinStations RDP-Tcp
I setup that port correctly as a port forwarder in my router. The original 3389 was working fine. However, the new 4 digit one is not strange enough (port forwarder is 'ok' according to one of those port forwarder checking sites). I tried to RDP from one network to my IP (confirmed correct) like this:
myipaddress:1234
1234 = being the actual port number I set up.
Of course, I do already have RDP enabled on both Windows 7 laptops.
What could be the cause of the invalid connection? It was working fine on 3389 by for extra security measures, I changed it to something else. I did restart the laptop as well.

It's been a while since I've gotten my sound "working," but my current problem is that only one of my audio jacks work, one on the back. I know it's not the hardware because it used to work on vista. It hasn't been that much of a pain because i didn't have to change often between audio output devices, so i just dealt with it- getting back behind the computer and switching out cords. Now i'm doing it a little more frequently, so I can still just deal with it, but if anyone here does know something that may help, it would be very nice of you to let me know.
