Windows 10: Help with dual display, settings refreshed

Hello

For months now I've been connecting my laptop to my HDTV via a HDMI cable and VGA + Audio > HDMI Adapter.

Originally setting it up took some work to get each device to communicate properly, but it's been working perfectly for months, up to and including last night.

This morning it looked like the display settings reset themselves somehow overnight. The custom scaling had been set to 125% (not me) and the resolution 1024 x 768 (again, not me).

Although the blown up display was still visible on the TV this morning, after I restarted I'm getting a No Signal message and the laptop won't detect the TV. It also kind of looks like I lost some high-res options in the drop down menu.

I've checked all connections and everything seems to be plugged in. I wonder if maybe the power supply to the adapter failed but that doesn't explain why I had the low-res image on the TV this morning; if the adapter has no power I get no image at all.

Another thing, previously I had Windows settings to "Display only on 2" but now it's not detecting multiple displays at all.

Please help !!!

Screen flickering in Windows 10

The only thing that worked for me was making sure I was not set up for dual display. I had the same problem, I was set up for dual display changed.it to single, worked for me maybe this will help, good luck.

 

Screen flickering in Windows 10

Check your display settings, make sure it is not set up for dual display. That is what I had to do to stop my screen flickering, hopefully this helps.

 

Tried using Device Manager to uninstall/delete display adapters and monitors.
Tried downloading AMD Catalyst software... won't even run. Says there are no settings it can configure.

Any downloads I find for the hardware come with this catalyst suite that won't run or do anything and it doesn't even look like it's repairing the driver.

AMD Radeon HD 3650

 

oook basically your case is a combo , devices (probably all of them) have updated without your consent and cheap adapter .

You might want to turn off device driver update through windows update (working only in pro version of windows) from Control Panel > System Properties > Hardware > Device Installation Settings > "No (Your device may not work as expected)" then save settings , uninstall both sound and video drivers and make sure you tick delete the drivers from store option so they wont keep coming back , reboot , then reinstall latest version from manufacturer .

Now I am not sure about if the adapter is detected as a device in device manager (showing either as a usb device if it gets its power from usb port or shows as a display or both ) , I assume you got one of those brandless things bought online so no practical way to download a proper driver for these but your best bet is to roll back the drivers if the option is there to your earlier working version .

Hopefully your problem is just the vga/sound dilemma and you wont have to roll down the adapter trouble shoot path .

 

Ho boy.
Thanks for helping me look into this.

So funny thing - I started looking through my C drive and there's friggen AMD and ATI files everywhere because I've been messing with it since I bought the laptop. Finally found a utility in one of the files as luck would have it removes everything to do with AMD. Also completely removed catalyst through the installer (as Control Panel never seems to work on its own for me).

Didn't go so far as to delete the USB devices (but hell I've done that before and the list has about 12 and by time I delete all the mice I'm using that dumb little red button from 2001) but yes you are right about the adapter it's looking like that .. might, be the problem. The brand is cablor.

I was just starting to wonder why my computer wasn't detecting the Radeon HD at all any more or the laptop display but instead giving me generic devices when the AMD utility required a reboot.

On startup, I'm wondering why my display blacks out and of course it's because I have to turn the TV on *Cool

Anyway I still don't have the resolution I had before and appears to be maximum 1400 x 1050 where before I think I had 1600 x 900... so still open to some more solutions to fix this if anyone can help.

 

The option was definitely not available to roll back the drivers, nightmayor
but do you think this will keep happening if I continue to allow automatic updates?

 

"and there's friggen AMD and ATI files everywhere because I've been messing with it since I bought the laptop.

It is not automatic updates that is the problem, it's you messing with drivers in the first instance. This happens to a lot of people with Laptops who should just be leaving it all to Windows updates and the manufacturers.

 

lol kind of a dumb thing to say when these things are keeping up with win10 9 years down the road.

I just discovered that at least 5 or 6 people are having the same problem at the same time as me. Must be that super awesome windows update keeping it tight. Anyway, there wasn't any need for me to post this thread I suppose now that I have discovered the many others.

 

which by the way is to find a way to roll back the drivers on the Network Adapter after Windows came through and phased everyone's display overnight.
Ironic wouldn't you say, Helmut?
