Shaky TV
Shaky TV
I removed the tv from the wall and placed it near my pc for better viewing. When connected to my computer, the display showed slight shakiness moving left to right. The colors were mostly accurate, though there were some flickering spots. The graphics card used was RTX 3050. I connected it via HDMI to a VGA cable that went to the tv. After updating the cable to a standard HDMI one, the problem was resolved. Lesson learned: Use properly edited cables.
The shaking screen would be very annoying to use if it were my monitor. I’d prefer a direct HDMI connection instead, or else it might be time to upgrade to a better device.
It’s unlikely the television is the issue. The HDMI to VGA adapter (not a regular adapter) changes a digital signal into an analog one. If there’s a small knob or screw on the converter, you should tweak the clock and phase settings. If the converter lacks these controls, the TV will rely on its built-in calibration or auto-adjust features (these functions aren’t always identical). The TV will try to match the clock and phase coming from the VGA adapter. Running the picture auto-adjust function manually is usually necessary, as it isn’t automatic by default.
The device is very simple—just an HDMI plugged into my PC with a VGA cable on the other side. It functions properly on my monitor but performs poorly on the TV.
