The HDMI to VGA adapter's VGA signal halts abruptly during certain visuals displayed on the monitor.
Hello, my problem is that the HDMI to VGA adapter occasionally shuts off under unusual conditions: My laptop has an HDMI port, while my monitor uses a VGA port. Generally it functions properly. The main concern is that with certain images, the adapter fails to convert the HDMI signal into VGA, and the audio through the adapter also stops. The adapter has a headphone jack on one side, which I used during testing where the issue occurs. The display resolution is set to 1440 by 900 in Windows, and I see the correct picture on my monitor via the adapter. When receiving video through the adapter, the audio works through the headphone jack, but when the VGA signal stops, so does the sound. This situation is reproducible. The image I’m testing is Minecraft; it completely cuts off both the video and audio when the screen is full-screened. The audio disappears even if I connect a brand-new micro USB cable to the adapter. I suspect the problem lies with Windows or a software/format issue rather than the HDMI port itself. This has occurred with two different adapters, and the behavior is consistent across both.
Switching to fullscreen on the PC will alter the display from the 1440x900 setting in Windows to whatever the game is configured for, probably something the adatpers can't handle. Try adjusting the resolution in-game, perhaps without the external monitor connected, and see if it maintains the same output when you connect it again. Check if you can fine-tune resolution or frame rate using configuration files or similar methods.
It's not during the game's full-screen switch. The problem arises without actually entering full-screen. This particular visual appears when full-screen is active (and also at certain zoom levels without full-screen), causing the issue consistently every time. It occurs on full screen and not just in full-screen mode, unlike other images which don't trigger it. I'm sharing the screenshot because it demonstrates how the adapter stops VGA and audio output—this image was captured while I played when the screen went black and reported no signal.
Additionally, there appears to be some visual distortion that I can only see in the lower portion of the screen.
Have you experimented with another VGA cable? The visual changes could stem from a failing noise reducer in your cable. Have you added any new electronics recently? Which VGA version are you operating on? Are you working with 8-bit color depth or another format? Which output color model are you employing: RGB, YPbPr, YCbCr, YCbCr444, YCbCr422, or another? What is your aspect ratio? Are there additional monitors connected? (You can adjust these settings more easily by downloading Intel Graphics Command Center.) What actions did you take on your computer before you observed any shifts? Are you an audiophile?
I haven't experimented with a different VGA cable, but I understand that even without it plugged in, the adapter's VGA signal drops when that image appears on the screen, along with the audio through the adapter. My laptop is brand new, and the HDMI to VGA adapter is also brand new. This issue has persisted since I acquired them, as I mentioned. I've tested it on two different devices using two adapters. The feed from both adapters stops working when the image appears (and some similar screens too). It mostly occurs in Minecraft, though it has happened a few times with Chrome as well. I don't know my VGA version, color depth, or output color, and I'm unsure how to check those settings. - The display ratio is 16:10 (1440 to 900), which is fine for a laptop, but only affects the extra monitor I connected. The NVidia control panel indicates it's using ViewSonic VA1903wb-2. I’m not particularly interested in audio quality. The sound from the adapter was just a way to confirm if the problem lies with the adapter cutting the feed when that image is shown. I used my laptop’s monitor to observe what was happening on the second screen without any VGA signal.
VGA typically doesn't accommodate 16:10 resolution. Consider using 16:9 instead.
Compare HDMI and VGA on the Diffen site and Wikipedia for resolution details.
Using a VGA cable compatible with WXGA+ enhances display quality.
