# Vizio E3D470VX "no signal" on laptop — force 1080p60 mode
|
|
|
|
**Symptom:** Vizio E3D470VX TV shows "no signal" when connected to the Framework laptop; link flaps ~4x then dies. Same TV works fine on other PCs (friend's Debian and Pop!_OS machines) → mode-negotiation failure on this laptop, not card/cable/TV.
|
|
|
|
**Diagnosis path:**
|
|
1. Cross-test the TV on another machine — if it works there, rule out cable/TV/HDMI card.
|
|
2. Compare with the Epson projector case: same class of problem (display advertises/needs a mode the laptop doesn't settle on). See [[monitor-not-detected-framework-hdmi-card-latch]] for the *other* display failure mode (card latch — kernel shows disconnected).
|
|
|
|
**Fix (applied 2026-09-16):** rule in `~/.config/hypr/monitors.lua` (outside the hyprmoncfg wake block):
|
|
```lua
|
|
hl.monitor({ output = "desc:VIZIO", mode = "1920x1080@59.94", position = "auto", scale = 1 })
|
|
```
|
|
`hyprctl reload` clean. Next plug-in should auto-force the safe mode.
|
|
|
|
**If "no signal" persists AFTER this rule:** the mode-rejection theory is wrong — investigate HDCP or i915 DP-to-HDMI dongle signaling instead.
|
|
|
|
**Hermes-system note:** Mnemosyne scrubs resolution strings like `1920x1080` as IP addresses when storing memories — write them with spaces (e.g. `1920 x 1080`) in memory content.
