HP EliteBook 820 G1 Display :: Connecting External Monitor - Cannot Display Video Mode
Sep 4, 2014
I am having problems connecting an external monitor, Dell 2709W, to my Elitebook 820 G1.
I have an Intel HD 4400 graphics solution. The monitor says:
Out of range signal
Cannot display this video mode
change computer display input to 1920 x 1200 @ 60Hz.
I use a Display Port cable for the connection.
My OS is Win 8.1 64bit
I have used the HP support assistant to update all hardware drivers...

We have several 8460p with the same issue. They work fine until you try to connect an external monitor/TV/projector and then the trouble begins.
When using Fn+F4 to establish a dual screen output the external monitor and the built in screen switches between the two as if the PC can not determine the screen to use. On rare occasions it works but it is not reliable. I´ve first encountered this on a fair and when I tried it before the session it worked well. During the session it just started this behaviour. I took it out and replaced the graphic drivers, the BIOS and made sure the resolution was not the issue. It worked well and I returned it to the lecturing room and it started again.
I started to believe the projector was the bad part here so I did not try to use the PC again on that fair but no other computer showed any sign of trouble.
Since then, this was early this spring, I´ve seen and experienced the same problem with several computers of the same type and with different monitor and they all behave the same way.
I have spent some time now and searched the web but nothing I´ve found does explain anything around this and so far no driver update and no other update (including a full installation) has solved this.
The computer are the HP Elitebook 8460p with AMD-graphics.
There are not any other indication of that something is wrong in logs or anything.

The monitor on my HP Pavilion dv9830us laptop has not been working for some time and I have had to use an external CRT monitor for my display. A couple nights ago, my operating system (Ubuntu Linux 10.04) failed to load and because I can't get video feed to my external monitor until the video drivers on Ubuntu loads, I am unable to run Ubuntu's repair feature and the beginning of boot.
Is there a way I can get my laptop to use my external monitor at all times, even at the BIOS screen? Is there a setting in BIOS for this?

I just opened up my HP Pavilion Touchsmart 15 Sleekbook and I want to connect a 2nd monitor to stretch my desktop. I have a Dell monitor that I've been using for a year or so with a VGA connection. On my new Touchsmart there is no standard vga port.
In what ways can I connect it?

Ok so the Studio 1737 premium display is the RGB LED display. Using LED's.
For example even high end HDTV's the most expensive $4,000 Samsung using LED back lighting lists a 2ms response time.
I have never seen such specs mentioned for the 1737's RGB LED display.
I know it has to be fast, because on my 22" Samsung LCD which is back lit using conventional CCFL has a 2ms response time.
and when I connect my 1737 to my 22 LCD via HDMI, I can tell that the response time, on the 1737 is faster, my guess is because of the LED's can adjust or turn on off faster than CCFL.

I was getting frustrated with my external monitor because the screen color was turning dark purplish at times, so I went into Device Manager and deleted both default monitor entries instead of just one under Monitors in hopes that it would've gotten rid of the purple haze so to speak.
I tried unhooking the monitor and unplugging everything before I deleted the default monitor entries in Device Manager, but it didn't get rid of the purple screen.
I have a fairly old notebook Dell Inspiron 4000 with WinMe installed and the display is no longer working assumed due to a bad or broken LCD, which is why I'm using the external monitor.
The external monitor has been working fine for months until it started turning purple on me when it was being used with the notebook. When the monitor is hooked up with my desktop, the screen color is just fine.
The notebook has got a lot of storage on it. During the boot process on the notebook, the external monitor lights up at one point (no longer purplish), but goes blank/dark after a few seconds and says it no longer is getting a signal from the notebook

I just got an HP Envy, 17 inch, and I have an HP 25 inch monitor I would like to connect to it. It has the "old style" connector which was supported on my old HP Entertainment Notebook. Not on the new one! What kind of adaptor do I need to get? I do have an HDMI port on the left side of my laptop. Do I need just a regular HDMI cable?

my resolution on my external monitor wont display correction when hook up with the XPS 1647.
The connection is HDMI. Resolution has been set to the highest recommend 1920x1080.
If you look at the picture below, the edges of the screen won't fill up the whole screen, making everything so small and hard to read. I already turn off the display on the laptop, making the monitor as my default screen.
On my previous XPS M1530, the Nvidia 8600GT can display the resolution correction.. I find it hard to believe that ATI card are not capable of doing that or there might be something wrong with my setting

I have a brand new HP Envy X2 (15-C001dx) with Windows 8.1. So far it works fine by itself. I tried connecting an external monitor to the laptop using an HDMI cable from the laptop to an LG L246WPQ display. The problem is that 10-15% of the left side of the laptop screen content does not appear on the external monitor. Missing from the external monitor is the word "Start" in the upper left corner along with roughly the 2 leftmost columns of tiles. This occurs in both "Duplicate display" or "Only display on screen 2" modes. This is using a resolution of 1680x1050 which both the laptop and the LG appear to support. Using the touch screen on the laptop I can scroll the tiles to the right and see the missing leftmost columns. The information that is displayed on the external monitor begins as far left as that monitor will display. In other words, there is no black/blank area on the left. Except for the missing information on the left side, the content of the rest of the external monitor looks fine. I updated the laptop's video driver to the latest on HP.COM. No change in behavior. I tried every option I could find on the LG OnScreenDisplay, but nothing made the display any better.

I have connected my monitor to an external monitor. It works fine. Only problem I have ( and a little irritating one) is that the external monitor picks up display only after Windows is loaded. Pre-OS screens like BIOS settings, GRUB loader (I have Installed Linux ) doesn't show up)
Is this an issue with BIOS? Because, when I connect HP dv6000 to my monitor, I can see the BIOS screen as well. I am sure the problem is not with the monitor.
The BIOS is responsible for detecting displays before the OS is loaded right? I checked BIOS settings and there is nothing to indicate the display ports/devices (however, this page on HP website shows a BIOS screen "Advanced" which apparently has those settings)

I have MacBook Pro (late 2008) and I have WinXP installed in Bootcamp.
Recently I acquired a Dell SP2309W monitor that is capable of 2048 x 1152 resolution. When hooked to my MBP and start in WinXP, the external monitor works fine in EXTENDED mode. That is, I can move Windows to the external monitor. The MBP display is the primary display, where the Taskbar is displayed.
What I want to do is make the external monitor my PRIMARY display, with the taskbar shown there. However, the "Use this device as the primary monitor" is greyed out.

I have a HP Pavilion dv4t-4200 CTO Entertainment Notebook PC model # A1M02AV and it has a VGA port, one that looks like a phone/broadband cable port, and one that looks like a USB port but indented on either side at the bottom. Can I even connect an external monitor? How do I find out if I have more than 1 video card? Besides the usual USB/headphone ports, I don't have any other ports. It says my drivers are up to date...but I don't even know what I should be looking for. Do I need to install something or buy some sort of adapter?
I am trying to connect a Dell external montitor via the VGA port with a VGA cable. The monitor has power but my notebook does not recognize/detect it. However, when I first plugged it in, my notebook display shrank into a square (vs the whole screen) so it recognized something...but nothing happened on the external monitor.
I tried detecting it via my display settings, but I accidentally changed some dispaly setting so that the home desktop only shows on monitor 1, but unselected my actual notebook display or something or changed it to be monitor 2 (even though monitor 1 does not exist), so when I plug the cable in to my notebook, all of a sudden my desktop goes away and it's a just a blank background screen - and I cannot access the computer display settings or anything.... when the cable is unplugged this setting looks normal, so I can't figure out how to fix it.

I discovered that my display wasn't turning on yesterday when I tried turning on my notebook. Luckily I was able to plug it into an external monitor with a VGA cable and I have a monitor in my office, but I really cannot be restricted to my living room or office to use my laptop.

My laptop was working correctly and then I booted up one day, the bios worked fine but then the screen went black. I connected an external monitor to the lap-top and the laptop display works fine. As soon as I remove the external monitor, again, I get a black screen on my lap-top.
I have run the full system option of the Dell diagnostics and have 2 errors, battery and dvd flash rom. I have ordered a new battery. I have also noticed that my lap-top does appear to get quite hot.

I have an hp compaq nx6330 (ex856av) using windows xp. last may, the screen turned black (i was told i need to replace the lcd), so i decided to use a generic external monitor. a couple of months ago, i had to have it repaired and the repair guy said he'll upgrade the OS to windows 7. things were working fine for about a month then the screen (external monitor, since the laptop screen is dead) starting having vertical gey lines (the entire screen). i played with the resolution and i was able to get rid ofthe lines a couple of times. are the lines due to using windows7? can this particular model handle any OS besides the one (windows xp) it came with?

Tried (and sometimes successful) to connect HDTV to laptop, Inspiron 5720. Now laptop screen does not display (goes black) without an external monitor physically attached. Tried using Projects and clicking on single laptop display, but if I disconnect the external monitor, the laptop screen just goes black. Not very portable if I have to lug around a second display.

I purchased my laptop about two years ago. A few days ago, the screen suddenly dies, and on boot, it flickers a few times with the proper display, but then goes blank. The backlight seems to remain on though. When I use an external monitor with the HDMI port, the external monitor works fine, however the laptop screen remains blank. Here's a video of what it looks like when I first boot the laptop: [URL] .....

I've got an E520 here that doesn't seem to want to display anything on the built-in screen, unless I've hooked the device up to an external monitor. I've attempted the following:
1.) Windows Key + P to change the display. (No good)
2.) Updated drivers. (No good)
3.) Changed primary monitor. (No good)
4.) Changed to Extended display, duplicate, single. (No good)
I'm not quite sure what else to do.

With this configuration if I have the 2 monitors running I can't get any picture on the laptop screen. I wanted to be able to use all 3 screens at the same time is this even possible, how to have all 3 screen working at the same time.

how to get an external monitor working with a HP DV9700 laptop? The screen is cracked and it's totally white, so I'm unable to do anything through the BIOS, desktop, etc.
I've tried Fn-f4 and every other f button combination.
The laptop is plugged into the mains, so there should be sufficient power for an external monitor.
I've also re-booted the laptop with the monitor connected and switched on.
There is no option to switch on the laptop with the lid closed, due to the position of the on-off switch.
The laptop is not networked, so I can't access the hard drive any other way.
I try it without the battery (not sure why?), but that didn't work either.

2 weeks ago I began having video issues on my system. At that time, I was able to get to the login screen and right after I logged in, the screen started blinking at a constant rate (about evey second). To fix this, I booted to the Startup Menu (hit ESC after power on) and got the text based menu. From there I could get to the nice little graphical Windows Startup Options Menus. I used that to do system restore back to July and this seemed to work for a couple weeks.Now when I start the laptop, it quickly goes to a screen full of little dots all over and I can't see anything. I was able to get the text based statup menu that listed (system info, sys diags, ..., Starup menu). But when I tried to get the graphics based menus, it immediately when to the screen with dots so I could not do any of the recovery or start up options (like safe mode).
Attaching screen shot.

After running my B570 (1068) with an extended display, the unit went into hibernation. On wake-up the laptop screen is indecipherable garbage. The second display will run to show BIOS startup but then reverts to the built-in screen - which is illegible. Toggling the F3 key does not get a good screen.
I read another post suggesting this is a hardware failure. What parts have failed?

I just submitted an order for a new vaio z and while waiting for it I thought I'd look into getting a nice external monitor for home use. After reading through the forum, I can't find any report of a vaio z owner successfully attaching an external monitor with a resolution of more than 1920 x 1200 (due to no dvi-dl compatibility). Specifically, I was hoping to get a 30" 2560 x 1600 monitor.
Is it safe to conclude that it is impossible to connect a 2560 x 1600 external monitor to my new vaio z?

I have Thinkpad Edge E330 bought this July, with win8 downgraded to win7. It recently started a problem where the laptop's own display doesn't display anything (just blank) if I don't have external display connected. The external display doesn't have be in use, just connected, and E330's own display works fine. If I disconnect the external display, the E330's own display goes blank also. It doesn't matter what display setting I have.Currently I'm not able to use my E330 as a laptop at all.
