Pc hdmi no signal on tv7/31/2023 ![]() ![]() Will try on the Sony TV later to see if there's any difference. ![]() booting up the MacBook Pro while connected to the TV: tried this on the offending TV, no signal during boot (only after starting OS X), although the Apple logo does show on the MBP's display.connecting via the motherboard's integrated GPU HDMI connector: this gives no signal at all, during or after boot - I confirmed the computer is running by remoting into it, but the display shows "no signal".Everything worked identically: no signal until Windows boots connecting a DVI-HDMI converter on both of the graphics card's DVI outputs (one DVI-D, one DVI-I), using the original HDMI cable, and on all three of the TV's HDMI inputs.connecting using a VGA cable via the DVI output on the graphics card with a DVI-VGA adapter works, so for now I'll have the VGA cable handy when I need to access the BIOS, but this is obviously a suboptimal solution.tested a completely different HDMI cable (different brand, etc.), on all 3 of the graphics card's HDMI inputs, with the exact same symptoms as before: no signal during boot, signal shows up after Windows starts.I've performed a bunch of tests to try to work out the issue and these are my findings: ![]() Question: is there anything I can do to get the TV to show the boot process, so I can access the UEFI settings, etc.? A Playstation 3 used to be connected to this TV (though it hasn't been used in months) and it usually worked fine, although it had an intermittent no-booting issue that I am almost certain is due to the console itself and not the TV. I also tried connecting the HDMI output on the motherboard (for the integrated GPU) to the Philips TV, but no signal was shown during the boot sequence either (at that point I didn't have Windows installed yet, so no idea whether it'd show anything after Windows boots.)Ĭonnecting a MacBook Pro (with OS X already running, not during boot) works fine. The Sony TV indicates that it is receiving a 1080p signal while booting, so it's not an issue of incompatible resolution with the Philips TV. Connecting to a Sony XBR-52HX905 TV also works fine during the boot sequence. Connecting the PC to an LG 23MP55HQ monitor, also via HDMI, shows the boot screen just fine. I tried all 3 HDMI inputs on the TV, but the behavior is identical. However, as soon as Windows reaches the login screen, the TV begins displaying correctly. When the PC is turned on, the TV shows "no signal" during the boot sequence and Windows initialization. The display is a Philips 32PFL5605D/78, which is a 32" TV with 1080p resolution support, and is running the latest (rather outdated) firmware available. I just assembled a computer with an Asus Z97M Plus motherboard and an EVGA GeForce GTX970 card (model 04G-P4-2974-KR). ![]()
