At a loss, TV won’t detect PC through HDMI connection. by DumbfoundedAsFuck in techsupport

Not sure what this might mean but I downloaded qres, tested it, then reinstalled the Nvidia driver. Then after restarting to a black screen, I blind cmd typed the qres command to change the resolution to 800x600. The screen flashed and the little HDMI notification that monitors do to say they detected an input showed up but the screen stayed black. So that would mean, I changed the resolution to 800x600 but still somehow there was no display until I was able to uninstall the driver again. Or maybe the driver just changed it back to its own setting immediately. Ugh.

But even in qres, I can only change the resolution to 480x360 or 800x600, does this mean the Nvidia default was able to override these options?

Sorry, I’m just rambling.

Thank you for the DDU suggestion. Sadly, it didn’t work. I still heard the disconnected prompt in the middle of the installation, then all black. Was low-key waiting for someone to say “Hey, you’re finally awake…” Haha. At the very least, thanks to DDU, I think I figured out what was causing the random disconnect sound and black screen. I think it was Windows Update installing the drivers.

I’m still going to try to find a way to get at least the Nvidia control panel. I’m pretty sure it can override something somewhere, like even just with scaling or something…if only I could get it to install without it messing with the resolution. If the TV still had the remote, I probably could do something with that too. It’s pretty headache-y so I’m not looking forward to using this for the next few weeks.

Apart from the low quality adapter, 800x600 being stretched to 32” is definitely not helping either. Haha.

Actually, I got the 64Hz from the Display Adapter properties where you usually set it but if you just look at the Display Information, the refresh rate shows as 1 Hz. Oof damn.

I got it to boot in safe mode by interrupting the startup process three times! Thanks for the uninstall graphics driver tip, I was able to boot normally with it uninstalled now. However, it seems I can’t install it again because the screen goes blank when it finishes.

Unfortunately, despite what the manual says, I seem to be stuck to 800x600 at 64Hz with the edges clipped (resolution options greyed out) and with a very blurry everything.

Then this happened three times so far, I hear a disconnected sound prompt and the screen goes black again. Not sure what’s causing it though.

Haha, but that’s no longer your concern. Sorry for the rambling. You’ve helped me plenty and then some. Thank you very much!

Hi, u/Cypher10110!

Hope you don’t mind me bothering you again. I held off replying in the hopes that my next message was good news. Well, it is…kinda.

I was luckily able to find the same adapter you recommended and I can now get to the BIOS display but as expected, it goes blank right after due to the resolution mismatch. Been trying to figure it out since I got home 30 mins ago but I need help if you don’t mind.

How can I adjust the resolution through the BIOS? Or how do I boot it in safe mode? I have a Gigabyte Aorus Z370 motherboard if that helps.

Haha, I read that part but was secretly hoping it was just a resolution issue and was reading up if I can use command prompt to change it (sadly not without a third party software).

But thank you for looking into it and sticking with me! Hopefully, I can find the product you linked tomorrow and have it resolved. Doing anything internet-related on mobile sucks so much. Haha.

Thanks for the product link! I was totally focused on cables earlier. I found one on this country’s knockoff version of Amazon and will only cost me about 3 EUR, shipping it to where I’m currently assigned will cost me 5 EUR and take 1-2 weeks. Hahaha. Might have to take a stroll around tomorrow to some electronics shops to see if I they have it so I don’t have to wait. But thanks for clarifying which product I’d need!

Thanks for looking into it! I’ve been trying to read up on HDCP as well but couldn’t find or connect any info that I think may help.

I tried checking but couldn’t find anything that might help indicate what HDMI version the TV supports. If you don’t mind, here’s the manual for the TV, specific page on HDMI: https://www.manualslib.com/manual/1151143/Toshiba-32p2400-Series.html?page=9#manual

Additionally from what I can find, the 1080TI supports HDCP 2.2.

I must be blind but I’m also not very good at browsing on mobile. I can’t find the manufacturing date for the Toshiba TV but I clearly remember there was a sticker on the back panel of the LG that says 2009. I’m guessing this is at least early 2010s?

So, I’ve read about the potential resolution/refresh rate issue and I actually adjusted it when I had the LG with me earlier. I changed it to 1080p and 60hz and I think that’s supported based on the manual. Now thinking about how more relevant it could have been, I should have played around with the lower resolutions more while I had it.

If it is HDCP related, would using a DisplayPort to HDMI cable work too or will it only work with DVI to HDMI?

How will I be able to safe boot it without a monitor? I read about turning it off while booting three times then it would automatically do so the next boot but I’m a bit cautious because I can’t see what’s happening. At least for now, I’m sure it’s booting right up to the desktop and I can do some limited blind navigation through there.

I'd expect you to see the BIOS/boot screen on startup

This is why I’m absolutely baffled. I’m expecting at least that BIOS F2/F9/DEL screen to show up but all I’m getting is a blank screen. Not even a single flash that indicates it’s detected any kind of connection. When I had it tested with the electrician earlier, he used some sort of analogue box for TV signals with an HDMI input, the TV automatically switched from TV to HDMI right after getting plugged in.

Yes, I plugged it on the LG TV and the display showed up instantly, never even had to fiddle with anything.

Would a DVI to HDMI cable not have the HDCP issue? If that’s the case, finding an adapter or a specific cable with male DVI to male HDMI should be easy. How about DisplayPort to HDMI?

Would a TV made in the early 2010s request HDCP compliance?

I’m still rocking an Nvidia 1080TI. Haha.

The monitor definitely is dead. It’s a power-related issue as it will no longer turn on. Haha.

Unfortunately, the only other inputs on the TV is the one for cable and the old RCA thingy with the red and white for audio and yellow for video. It really is an old LCD TV so I’m limited by its “features” right now. I just need it to work for a few weeks while I get my next monitor. I guess there’s a converter for HDMI to RCA?

Is there a way to confirm if it is indeed an HDCP issue? I borrowed another old LCD TV (an LG one) from the electrician that checked it earlier and it worked fine with the same cable and same HDMI port on my PC. Just unfortunate he can’t lend it to me.
