Hello, I recently acquired a new TV (HISENSE 58A6N) but when I connect my desktop PC via HDMI, I get no signal.
Tests already performed (1-8)
- Tested with several HDMI cables and multiple HDMI ports (on the TV side)
- Works perfectly well with my old TV.
- HDMI connection to the old TV then booting the PC to the Windows desktop, hot unplugging then plugging into the new TV = Image OK, Resolution OK, Refresh rate OK (VRR)
- Tested with another more "powerful" power supply (just in case) = Same result.
- Tested with the GPU in another PCIe slot = Same result
- Tested with a DP to HDMI cable = Same result
- Diverse tests by modifying the TV settings
- HDMI connection of a laptop with a dedicated GPU (RTX 3050) = Works perfectly
I am losing hope day by day, especially since the PC works wonderfully when following step No. 3, which makes no sense...
For example, if I perform a simple restart while remaining connected to the new TV, the PC indeed restarts but without video signal, which does not happen with the old one...
Hardware:
- RX 6750 XT Challenger Pro (1x HDMI, 2x DP)
- New TV: HISENSE 58A6N (4K / 148 CM)
- Old TV: THOMSON 40FD2S13W (1080P / 102 CM)
- HDMI cable 2.1 / 4k / HDCP 2.3 / 48Gbps 2M
Additional notes:
- No errors on the GPU during boot (LED), the PC boots well into the OS in the "background"
- No integrated GPU (processor lacking graphics capabilities)
