Graphic Cards :: Duplicate Monitor To TV Via Hdmi No Longer Works

Dec 29, 2015

It worked fine in windows 7 but now when I choose "duplicate display" from the side menu popup the tv goes blank as if Ive unplugged the hdmi. All 3 of the remaining display options work including the extend display and tv only setting so its not a cable issue. Laptop model is XPS 17 L702X. Now when I used to do it in win 7 sometimes it wouldnt autodetect it so I would have to right click desktop, open invidia up and click rigorous display detect or something like that and then laptop screen would blink and make the beep noise like when hdmi cable got connected. Now in the invida panel it just simply wont allow mirroring, nothing happens when I right click on the display box that would normally show 1 and a smaller box would say 2. I dont get it but Id really like that feature back If its something simple I could do.

Main Monitor Only Works When A Second Monitor Is Plugged In?

Sep 23, 2015

I am running Windows 10

MSI R9 390 GPU
AMD Catalyst version 15.7.1
Main monitor is CrossOver QHD270 via Dual Link DVI
Second display is a Vizio TV via HDMI/DisplayPort

So I was messing around with a 3 display setup for the first time today, one monitor (DVI) and two TVs (one HDMI, one DisplayPort). Everything worked okay, and I could unplug one TV, but when I unplugged the second TV, my monitor went to a black screen. As soon as I plugged the TV back in, the monitor started working again. The main monitor I use every day is now completely dependent on a TV I occasionally use as a second display to be plugged in to function. When I turn on the computer with just the monitor plugged in, I can see the BIOS load up, and the first Windows 10 logo, but as soon as the password screen should be shown, the screen goes black. I tried uninstalling my graphics drivers. When the drivers were completely uninstalled, the monitor functioned normally, but as soon at AMD Catalyst Control Center was reinstalled, it went black until the TV was plugged back in. I've tried plugging the TV up through HDMI and DisplayPort, it makes no difference. Also, my monitor is listed as the main display in both CCC and Windows 10 display settings. Every once in a while when I unplug the TV, the Monitor will get darker and slowly fade to black instead of going straight to black.

Ethernet No Longer Works

Aug 2, 2015

I upgraded to windows 10 on my desktop pc on july 29th and haven't had any problems since. I know that upgrade/updates are forced to happen so when random issues occurred today I feel that maybe there was an update sent out? My ethernet no longer works, only to connect outside my LAN, but I can still remote desktop and access the computer so the port/cable still work and the router works for all other comps over ethernet. The internet goes in for a split second when I reset the adapter but then instantly goes out. I also noticed when launching a steam game the xbox controller no longer works to control it despite it working yesterday and the controller will control steam itself just not the games. Should I downgrade to windows 8.1 again, since I don't have internet anymore any fixes wouldn't even reach my computer?

Networking :: Open Network No Longer Works?

Nov 5, 2015

Prior to W10 I had a network NOT using Homegroup. Network worked who needs it? Now, I see some of my devices on the network, but when I try to share files I get a window requesting user name and password. Never used passwords before. I think Homegroup is sneaking in there, but all the devices say they don't have a Homegroup but some of them say the see a Homegroup on other devices. I've disabled Homegroup on all devices tried changing advanced network settings to no avail.

Installation :: Win 8.1 Dual Boot No Longer Works

Sep 15, 2015

I have 4 partitions.
1 => System Reserved
2 => Win 10
3 => Win 8.1
4 => Storage

When I try to boot into the win 8.1 it gives me an error. Even after restoring the win 8.1. partition from a Macrium image.

What gives? Two days ago I decided I wanted to shrink the win 8.1 partition.

I made a macrium image of my Win 10 partition (because I'm not crazy) and I already had a macrium image of win 8.1. I started shrinking the 8.1 and the computer went unresponsive so I rebooted. I used EASEUS Partition Manager.

I found out later that the reason the computer halted was because the version of EASEUS I used was outdated.

I attempted to boot into 8.1 and was greeted with the error. (Will update this post presently with the picture.)

I updated EASEUS and successfully shrunk the 8.1 partition. I took that unallocated space and enlarged the WIN 10 partition. Still unable to boot into 8.1.

Used macrium to overwrite the 8.1 partition.

Computer refused to boot completely. No Win 10 or Win 8.

Macrium restored the Win 10 partition, and the Win 8.1 partition. Discovered something interesting. Macrium restored the partitions as if I had never shrunk the 8.1 partition and enlarged the Win 10 partition. Is it supposed to do that?

Still unable to boot into Win 8.

Drivers/Hardware :: Canon MP250 Printer No Longer Works?

Jan 4, 2016

When the print spooler is turned on I get a message that says the printer queue is full. (The printer queue is empty.)

If I try the printer without the printer spool on i.e. print directly to the printer, I get a message that says "Unable to create a print job."

This printer was working with Win 10 until recently. The scan function works as it should. So the computer does see and interacts with the printer through the usb port.

Something must have changed in the latest Windows 10 release to gum up the works.

Browser/Email :: Viewing Local Video Files In Chrome No Longer Works?

Dec 22, 2015

I'm trying out the chromecast device to hopefully eliminate having to move my laptop across the room and connect it via hdmi every night to watch movies on my tv screen. In windows 7 I could just drag the file into a new chrome page and it would open the file which could then be cast. Now when I drag a movie file into chrome it creates a download window in the bottom of chrome like any other file download, and then if I open it from that it just opens my default video player and plays the movie file. Any way to view local video files in chrome browser like you could in windows 7?

Networking :: IPv6 Not Working On Laptop - Works On Other Computers On LAN

Nov 15, 2015

My router is supplying IPv6 to all the LAN clients in my house. In particular, IPv6 is working on my Windows 10 desktop computer, but not this laptop. This laptop is a Windows 10 Pro OS, and I don't see IPv6 connectivity when I look at the connection in the Network and Sharing Center. When I look at the network adapter (wired) properties, it shows that IPv6 is enabled in the networking software.

The laptop used to have IPv6 connectivity with Windows 10 before I installed the giant threshold 2 update last night, now IPv6 not working on the laptop.

what I can do to diagnose the problem with the laptop? I've run the Windows troubleshooters, and they don't find any problems (of course). Even my Apple and Android mobile clients have IPv6 connectivity.

After a recent Windows 10 update on my laptop and my work computer the date no longer shows on the taskbar. The clock is visible and the calendar pops up when you click on it, but no date. No settings were changed by me and everything is enabled as far as I can tell. Is this just some sort of glitch or is there something I am missing to bring the date back?

I tried that Windows 10 registry fix, and my laptop no longer recognizes my password. It keeps saying my password is incorrect. I got the update error on both of my laptops, but I tried the registry fix on an older laptop before I tried to fix it on my main laptop. My laptop starts fine and I get to the log in screen okay, but my password is no longer being recognized as correct. Did I destroy my laptop? I followed the directions exactly.

Making Laptop Boot To External Monitor?

Oct 15, 2015

I'm trying to just run my laptop as a desktop, as the screen hinges are faulty. Its a Lenovo Y410P. I know how to switch the display to the external monitor in the control panel settings. But I want to make it so that I can put the laptop to sleep or restart the laptop, and upon boot up have the login be displayed on the second monitor exclusively.

Currently, when the laptop is started from sleep or restarts, it will display everything only on the laptop screen. Then I have to open up the laptop, switch settings and send it to the external monitor.

Monitor is a ViewSonic VA2265smh. I'm running this via HDMI cable.
