TV fails to function during connection to a desktop PC through an HDMI port.
TV fails to function during connection to a desktop PC through an HDMI port.
Hello! (Just checking if this is the right place) I wanted to ask for advice here because this seems confusing and isn’t making sense. It would be much simpler if I could handle it myself. I own an older PC (a new one is coming soon, but not yet) with a 1050 Ti. It functions perfectly on my two standard screens—a larger 27" at 240 Hz and a smaller 60 Hz side screen used vertically. However, when I connect the TV via HDMI, it doesn’t work, and Windows won’t even recognize it. The same happens with my laptop (an HP EliteBook with an Intel GPU). I bought a long HDMI cable for this setup, which feels odd now. Here’s what I know and why this is puzzling:
- I was using Windows 8.1 before upgrading to Windows 11; I thought the older version might struggle with multiple displays, but it hasn’t changed.
- Previously, connecting the TV instead of the main monitor into the same HDMI port worked fine, but now it doesn’t either.
- Recently, I’ve tried updating drivers and tweaking settings in both Windows and NVIDIA controls, but nothing helps.
- Oddly enough, using a DisplayPort connection on either monitor also failed—only HDMI works, yet Windows ignores DisplayPort.
I’m trying to figure out if this isn’t due to an outdated graphics card (bought in 2018) or if there are other factors at play. I’d appreciate any suggestions before I might have to replace the PC and feel let down again. Thanks a lot, and have a great holiday season! [Attached HWinfo might be useful]
Are you connecting with that extended HDMI cable? I've used a shorter version and had the TV as the sole display. Sometimes the TV requires checking settings for 4K60 compatibility.
HDMI cables in long form aren’t worth it anymore. I tested numerous passive options until I found one that really handled 1080p at 60Hz, then again for 2160p at 60Hz. When I needed 2160p at 120Hz, I switched immediately to optical since I was confident. Starting with optical from the start might have saved money later. Of course, optical cables became more affordable by the time I got my current TV. I own several from this brand in different lengths and haven’t had any issues. They’re also handy for shorter runs because they’re thinner, which reduces stress on the HDMI ports.
I connect the laptop using the same long HDMI cable, and it functions perfectly. I also recall moving the TV closer to the PC and testing with a shorter cable, but that didn’t help either. Everything remains at 1080p resolution. The only exception is my main monitor, which runs at 240Hz, but I attempted changing it to 60Hz without any improvement.
Apologies for the interrupt, but I'm checking for alternative options. It seems the same cable functions well with your laptop. However, it might be related to an older graphics card issue—though that wouldn't necessarily affect future PCs. (Reminder: no 4K support, all displays are 1080p, and everything runs at 60Hz except the main monitor at 240Hz.)
Ensure you're using the latest 1050 Ti firmware. It handles Display Port features, which might assist with your problem—though I’m skeptical. Adjust these configurations: Disconnect the TV fully, press the power button to remove any leftover power, attach the HDMI cable to the turned-off TV, restart the computer, and then turn the TV back on. See if the system recognizes it.
