External Display NOT WORKING - Need To Reset Flicker Rate?
Jun 20, 2011
I have a Dell Inspiron 1012 running Windows 7 Starter SP1 and I've got it hooked up to my Protron 42" LCD screen with HDMI cable. I changed the flicker rate to 70 Hertz without checking the Proton's maximum flicker rate - yeah, that's really SMART - so now I've got an issue with my external display.It worked okay for second but then my laptop screen turned black and the external display reads "Signal Out of Range" (duh, the Protron works only up to a 69.8 Hertz flicker rate, which I SHOULD have checked BEFORE changing it, but what's done is done -_-).Now, when I plug in the HDMI cable, my laptop screen goes to black and the external display still reads that same message. I can't change the flicker rate without seeing the menu on my laptop screen.

I am copying files from a WHS 2003 to a back-up drive on a HTPC. The WHS and the HTPC are connected physically to a router. The back-up drive is USB 3.0 and plugged into a 3.0 USB input on the HTPC.
The transfer rate is only 40MB/second. Why is this? The data is being transferred via CAT6 cables from the WHS/Router/HTPC and then USB 3.0 to the external drive

When a link is launched from IE9 and needs to open in a different application, then a couple of security questions are presented before launching it for the first time. How can I reset these questions? (the selection made) Preferably, just for that type of link. Or alternatively, for all such questions.

The users on this site have been amongst the most knowledgeable I've seen on the net. So anyhow, I have this laptop with a broken screen running Windows Vista and I plan on wiping it clean and installing Windows Server 2008 to use as a media center PC in the bedroom. When logged on to Vista, I can use the function keys to pull up the external, however, I am unable to do the same during Server install. How can I remedy this issue? I put this in the Windows 7 forum due to the similarities between 7 and Server 2008, the fact that it is not really a "server issue".

yesterday, i got 2 blue screens in my windows 7 home premium. i have an hp envy laptop. i had updated my video driver (ati mobility radeon hd 5850) earlier in the day (although i experienced similar blue screens with my old video driver version too...the old one was also the mobility radeon hd 5850, just an earlier version). i was trying to watch an online video in internet explorer 8, and i got a blue screen. so i had to do a manual shutdown. when it started up again, i chose for windows to check online for a solution to the problem (but windows never got back to me with one, if it found it). later on, when trying to watch a Internet video, the same blue screen appeared, and once again i had to do a manual shutdown. it may be related to my ati mobility radeon hd 5850, maybe even other things which i can't be sure of...also, i mentioned that i got similar bsods with my old video driver version too. at that time, i'm pretty sure i was using firefox instead of ie when trying to watch the online videos. by the way, i was able to watch several Internet videos normally yesterday, but on one occassion i did get that bsod. also, here is what at least part of the bsod said (on both occassions yesterday): "attempt to reset the display driver and recover from timeout failed"

I am constantly using my netbook for school work and other things. I often have to plug it into external monitors by HDMI output, and all worked fine until yesterday.Now, when I go to Desktop-> Screen resolution (to choose my display), I always have an extra option even if I'm not connected to anything. It's called "VGA Display Device". If I'm right, it seems that my GPU detects my VGA driver as an external display, like a bug/glitch or something.

My work laptop, an HP 8560p, crashes after a period of time with an external monitor connected to it. Crashing can occur anywhere from a few minutes after rebooting to a couple hours after rebooting. There is no BSoD when the laptop crashes; the laptop just shuts off and automatically restarts. I have not been able to replicate this issue without an external monitor plugged in. The issue happens with the external monitor plugged in via direct to the laptop or through the dock; VGA or DVI.
So far I've tried:
A clean sweep of the video drivers and testing both the windows display drivers and the ATI drivers.Sending the laptop to HP, where they completely replaced the motherboard.Currently running memtest86+ (currently 2 passes through without any issues).

Well, running Windows 7 ultimate on a Dell xps m1330 laptop. Everything looks good, but at work I am connected to a matrox triple-head-to-go device which is connected to (3) 22' monitors (3840x1280 resolution). Now when I connected it, ran the nvidia app, it found it and worked great.
Problem is I get home, no external connected, so running off the laptop with the basic resolution, I am trying to start apps (firefox, stickies, etc.) and I guess they were in other spots at work as I don't see them.
I forced a close on FF, then re-started, rt clicking and maximizing which worked, but then other apps like stickies don't have that option. An alt-tab shows it running in the lower right (see screenshot), but there is absolutely no way of getting to the app! I did close the app completely and restarted, but it does restart in a location not on the screen.

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 a HP Pavilion dm1z laptop. The laptop has a HDMI port. I am trying to connect it to my Samsung BX2335 display. The display has the DVI dual link port only. So I bought a HDMI - DVI adapter.I have Win7 x64 on my laptop.When I start the laptop with the external display connected, the picture is duplicated on both the laptop and the external display. But as soon as Windows starts, the picture will only be displayed on the laptop, 'Starting Windows' being the last picture shown on both displays.After some investigation it seems that windows could not detect the external display successfully. In the 'Screen Resolution' window the external display is shown as 'Display the device on: VGA'. It is impossible to view the properties of the external display, as the option is disabled, and the display is called 'Default Monitor'.I tried updating the AMD Radeon Catalyst drivers, but this did not help. Tried to install the external display drivers, but these installed as the mobile device display drivers.

Firefox browses and navigates fine, not a problem. Only when scrolling either with arrow or mouse, the background and sometimes the taskbar/system tray flicker. It's like you can see what window is open behind the browser view.I have tried using IE (not a fan...) and it didn't work so I uninstalled Firefox and attempted a reinstall only to find the problem remains.

I just got Windows 7 Home Premium today and installed 64bit edition. I must say, I'm over the moon. Great OS. Have a very small annoyance issue I was hoping someone could tell me is a result of a feature that I can turn off that isn't a major.
So here's what's happening
In Windows Explorer / My Computer when it's maximized "full screen", when I double click a folder and navigate around the directories, the screen changes brightness to bright then back very quickly to the original level (it basically flashes). If a folder only has a few other files inside of it, it even changes brightness when I hover over the icons.
It's not a major and doesn't do it when it's not fully maximized. Even if I make it the size of the screen by dragging the corners when it's restored down it doesn't do it. Very weird, and kind of hurts my eyes, especially when it's getting late at night and I should be in bed already.
When I disable visual themes, the problem goes away, but then it looks like rank, and I want to have all the flashy things that are unique to this version of windows, so...

I'll keep it short and sweet here. Just did the Windows 7 - 64 Home Premium install and did all the Windows and HP updates (yes, video driver is up to date - Nvidia 9300GSm). My screen is flickering for a 1/10th of a second every 20-30 seconds or so. It is incredibly irritating lol. Any ideas?

After doing upgrade desktop icons would flicker and after some time the screen resolution would change. Then computer would stop responding and would only respond after forcing reboot. I contacted Microsoft and they had me do a clean boot which stopped the problems.
I restarted non-Microsoft processes one at a time and the problem seems to be caused by NVIDIA Display Driver Service. As long as this is not running computer seems to be fine. Only question is this something that is needed to run? When on Vista Home Premium before upgrade to Windows 7 there was no problem with this running.

Sometimes fingernail-sized parts of my screen flicker. Are these called artifacts?
They smooth out when I drag the mouse pointer over them.
My drivers are as new as can be.

I think I accidently changed a setting as I was customizing things. When I right click on a program and select properties, I'm no longer getting the window that normally comes up to let you change settings. If I hover my mouse over the Explorer icon on my taskbar, I can see the thumbnail view of that window. But I can't get it to expand.
Any ideas?

I have my Iiyama prolite connected via dvi and another TV via HDMI.As soon as the HDMI is plugged in I lose the DVI display and it transfers to the HDMI. The DVI is no longer detected.Does this mean if I want a second monitor I will have to set it up through VGA?
