"generic NON-pnp monitor" fix? no solutions I've tried have worked for me.
"generic NON-pnp monitor" fix? no solutions I've tried have worked for me.
So, I have an older-ish (last 5 years I think) TV that before now, l've had plugged into my computer, and it sits near my bed for media streaming and the such.
I had a GTX 1060 6GB and it worked completely fine, like a dream, absolutely no issues
I recently upgraded to an AMD RX 6700 XT, and now, l'm having extreme issues with it.
First and foremost, it always shows up as "Generic Non-PnP Monitor" in device manager. Second, there's no sound driver so it doesn't play any sounds. Third, and I don't know how 1 fixed it, but it'll only display in 640x480.
l've taken many steps to try to fix it, and I'll list them and what it ended up doing.
- Unplug HDMI, replug- no change
- Uninstall driver in device manager - no change
- Manually update driver to "Generic PNP monitor" or "Digital Flat Panel 1920x1 080" or "Generic Television" -no change. Driver does not update
- Use DDU to clean drivers (in safe mode) and reinstall- Works, until I restart my computer, then goes back to Generic Non-PNP
- Unplug TV from power, wait 10 minutes, start it up again -no change
- Use different HDMI cable - haven't tested yet, don't have one long enough
- Use different monitor - other monitor works fine. Had an issue at the beginning, but unplugging HDMI and putting it back in made it work
Notes- The 6700 XT has 3 displayport connectors and one HDMI. The 3 DP spots are filled up by the monitors at my desk. 2 DP to HDMI adapters, and one DP to DVI adapter. All of the monitors at my desk work fine
The HDMI going to my ty has a lot of plastic around the connector, so when plugging into my GPU,I think it's not connected all the way. I understand this might be an issue
I have used CRU to try to copy all the info from when the TV was working, to the device where the TV isn't working. When I use restart64 to restart GPU drivers, it makes no changes
Like I said before, I used DDU to try to fix. Here is what I did
- Boot into safe mode
- Clean Nvidia drivers (from last GPU
- Restart, boot into safe mode
- Clean AMD drivers
- Restart, install AMD drivers This did not fix the issue.
Any help is greatly appreciated!
With further inspection: the TV, connected to the HDMI port of the GPU, (with an HDMI cable) is detected as HDMI until computer reboot or GPU driver reboot with CRU's restart.exe. after that, it is detected as DVI-D. I was able to use CRU to consistently output 1920x1080, but I don't get audio, because y'know, it's being detected as DVI-D.
You're viewing a single thread.
I'm kind of behind the times with graphics cards, but do you have 4 displays hooked up at once when the TV is plugged in? If so, are you sure the card supports 4 displays? The last amd card I had, the HMDI port was tied to one of the displayports. You could only use one of the two at a time.
This was probably 5 years ago so not sure if it's still relevant.
Yeah, I do have 4 total displays. The GPU has one HDMI and 3 DP Inputs.
Two monitors use 2 DP Inputs with a DP to HDMI adapter
One monitor is using one DP Input with a DP to DVI adapter
The TV I'm having issues with is using the HDMI port, with an HDMI cable. No adapters.
What brand is your 6700? Might be able to find a manual for it.
Just wondering if it really only supports 3 displays.
It's the Powercolor Fighter 6700 XT. I have the box next to me, but of course, no manual.
Also I just tried unplugging my DVI monitor and it's still doing the same thing mentioned in the OP.
The weirdest thing is that the TV will be detected as HDMI, until I reboot computer or graphics drivers using CRU's restart.exe, and then it'll be detected as DVI-D, meaning no audio. I've gotten it to output in 1920x1080 but I just can't get Audio output, because, y'know, it's being detected as DVI.
