JideTech VGA to HDMI Converter with Audio, One-Way VGA Source to HDMI Display Adapter, 1080P Active Converter, DC 5V Powered, 3.5mm Audio Input, for HDTV, Monitor and Projector

I am giving this 5 stars as it works as advertised but I made a stupid mistake and searched for 640 to see if this supports 640x480 so I can use this to see my BIOS screen and found a review that said it did. The description clearly states that the lowest resolution is 800x600. I missed that in the description and thought this would work in my situation but it does not. I'm very disappointed but cannot give it any lower rating as it does what it states it does. I need to find one that will upscale a lower resolution.

It works well for the resolutions it supports, with clean output and no waviness unlike many adapters I've tried in the past. I initially planned to use this on an old PC with DOS/Windows 98, however it did not support the text modes necessary for the DOS boot menu I'd set up or the BIOS configuration on the old PC. It worked if I put a GBS-Control box between the PC and this box's input, but the output then became a mess with waviness and crushed colors. It did however work flawlessly with my Dreamcast VGA box, which was using an OSSC to connect to my television up until now; I put the OSSC on the PC, where that works with the weird text video modes this fails to display, and used this with the Dreamcast VGA box where it works without any issues since the Dreamcast just needs 480p. I'm happy with it as a Dreamcast VGA to HDMI solution, even if this isn't the configuration I expected when I bought it.

I'm preparing to purchase a new TV to replace my ancient relic that had a VGA input on it. My A/V setup includes a computer with an VGA output, to stream online courses and such. I've previously had a great deal of trouble with such converters. Either they are very limited in resolutions they can convert, or have a very bad conversion quality. This one just worked! When I set the computer to a lower resolution that's uncommon these days, it followed right along without complaining. The sound adapter was also perfect. It's also built like a tank. A bit pricey but I ended up feeling that it was good value for the money. I would certainly buy another if I needed this functionality again.

I bought this active VGA to HDMI converter to use with the VGA output from server motherboards. The good news is that it does show the BIOS / UEFI configuration screens along with the splash screen just before that. From that point on in the boot process, this converter works fine. Other VGA to HDMI will often not show any output until the OS is booted. For this reason, I'm giving it four stars, because it's at least useful for changing BIOS settings. The bad news is that it is not showing the very earliest diagnostic messages from the ASPEED AST2600 BMC. These messages do correctly show up when using an HP LCD monitor with a VGA input. Had this worked, I would have given a five star rating. The unit is solidly constructed with holes for mounting screws. But, since it's made of metal, you could just slap a strong magnet on it, and then stick it on your server rack or chassis. Being made of black-painted metal with prominent white paint declaring what it is, "VGA to HDMI", it has a sort of server class feel to it. If you don't need to see all of the boot diagnostics, this unit should work fine for server management. Otherwise, you need to either use a true VGA monitor or some other solution. I've tried several and, while this one's the best so far, it falls just short of what I want in a VGA to HDMI converter.

It Did The Job !!

It works

I have a gajillion monitors scattered over a wide area, using the 1080P format (1920x1080, 30 Hz). I use a lot of KVM over RJ45 extenders (uncompressed), raspberry PI with VGA to receive information over the network, and just old PCs. That is to say, I have a mish-mash of DVI, HDMI, Display Port, and VGA to deal with - while modern inexpensive displays are HDMI, and that's about it. Rather than replace some expensive hardware to mate up with new displays, this is an inexpensive work around that provides excellent results. Most modern displays have at least one USB port as well, so I can use my USB A - to 2.1mm male barrel cables to power this device. The unit uses 5VDC at 500ma, so no need to use the clunky power adapter that comes with it if I have that USB cable (not provided with this device - it is a separate purchase). I looked at units (with male pins) that plug directly into the VGA port on the video device, but male units are more likely to be too bulky to fit behind the device. This connects to the VGA cord, then I just attach this device to the back of the display and use short HDMI and USB cables to finish the install. If I need to extend the distance between the device and the display, this isn't a bad way to go.

Been searching for a product like this for a long time. Easy plug and play set up and VGA to HDMI was flaw and looks amazing, no lag. Highly recommend!
