[SOLVED] Not able to connect to TV using HDMI

lxs602 · 08-01-2019, 09:20 AM

Hi,

I have not been able to connect to a Philips TV 42PF521/10 using HDMI. It has worked for another TV recently: https://www.linuxquestions.org/quest...ng-4175658295/

Do you have any suggestions on troubleshooting?

Is there any way to try to force HDMI output to the TV (even though it is not detected)?

EDIT:
I found these pages suggesting obtaining the EDID from the web/or from Windows, which I will try if I can

Can you check if this TV works at all with another device or with another cable? If you cannot even get its EDID it might be broken.

lxs602 · 08-01-2019, 11:43 AM

Hi, yes, it connects fine to a Virgin TV box with the same HDMI cable ...I will try with a Windows laptop if I can.

average_user · 08-01-2019, 11:56 AM

OK, so it looks ok. You could try other HDMI connectors. There is definitely something wrong on the hardware level.

Shadow_7 · 08-01-2019, 02:46 PM

What GPU? Intel? AMD? In debian buster with my AMD gpu, I had to add "firmware-amd-graphics" to have external monitor support. Which I didn't have to add in previous generations of debian. But I start with minimal installs.

$ lspci -nnk

You might also try the nomodeset kernel parameter. In either case it seems like you might be using fbdev or vesa drivers. Which are limited. Beyond that you could have a BAD HDMI CABLE. I've had that issue before. Perhaps other issues if you're using an HDMI to DVI adapter, which might block any EDID information from being seen. You don't need EDID to use the monitor, but having to manually setup a modeline to use the monitor kind of sucks. My guess like a previous poster is a hardware issue, aka bad cable.

lxs602 · 08-18-2019, 09:12 AM

Success! I found edid settings below. I don't know why I didn't find them before.

I have a 42PF5421 Philips 42" HDTV, and its native resolution is 1366 x 768, but in the manual it lists the supported resolutions for PC use as 800x600 and 1024x768. I've read somewhere that I can ruin the TV by using wrong resolutions, and I don't want to do that. It's connected with a HDMI -> DVI cable, can I use any widescreen resolutions that are under 1024, or can the PC resolutions also go up to 1366.

I also tried another laptop using a VGA->HDMI converter, which gave the modeline below, for a 1366x768 resolution, which gave a working display through the TV.

2005 was pre HDMI turn over for the USA. pre-OTA television anyway. AKA digital / ATSC. But under timings it has a few modes. Noticing that anything over 720 vertical is interlaced, not progressive. It seems it could do those interlaced modes. Not sure if that's at "native" resolution. Modern displays are pretty good about protecting themselves from bad settings. So might as well try if that interests you. Just be prepared to be blind until you reboot, or re-install if you don't have recovery "methods" that you can use (while blind) or via chroot on other installs / hardware.
