Hi,
Does anyone here use a VGA to HDMI convertor ( see link below ) I have one that I bought from the supplier about 1 month ago. I want to connect my Lumagen Vision ( Video Scaler ) to my projector via the HDMI input. As the Video Scaler has a VGA output, I want to input the convertor between it and my brand new Mitsubishi HC6500 Projector ( still in its box ).
The convertor states that it can convert a VGA 1080p signal to a 1080p HDMI signal. I asked the salesman at the time of purchase and he said this was true. As they are unable to help me with anything more definite than that, I just wanted to know if anyone here has used or tested one, as I am afraid that I might connect mine up and blow something up.
If you can advise me or help me, I would greatly appreciate it. Thank you.
Regards

I've used a Gefen VGA to DVI Scaler Plus over the past months. Excellent little machine. via eBay in the same price league as the one linked.

Doesn't the Lumagen Vision have a DVI output on it's own ? Why the need for an external converter ?

I am confused. If you have the Lumagen (which as the other poster said uses DVI), why not just feed your VGA source into the VGA input on the Lumagen, and then pass it DVI out to the display? In other words, why do you even need the adaptor?
The only adaptor I see you will need is a DVI to HDMI, which is just a small $10 part...

I have a similar question as I would like to hook my pc's vga to my Sony KV32HS420's (this is a CRT 1080i tv) hdmi port. Monoprice has such a gadget, much cheaper but with mixed reviews, none for a crt.

Another option: buy an inexpensive video card for your computer that will output HDMI. As an example, ATI 4350 (http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010380048+106792627+1320923120+1067944922&Configurator=&Subcategory=48&description=&Ntk=&SpeTabStoreType=&srchInDesc=) series cards are available for about the same $$$ as the converter.

Many computer video cards include HDMI these days and even the inexpensive ones will hardware accelerate HD video; for more $$$ you can get better 3D acceleration for games.

99.9% sure this will not work. Your TV only takes interlace, and PC's output progressive (though admittedly I haven't worked with this particular TV).

Unfortunately, older computer has an agp slot, not pci-e, but the onboard vga is sufficient for my uses. And I am a cheapskate.

Actually it does handle progressive pictures and here is a description of its capabilities: The set's standard 4:3 aspect ratio, Hi-Scan 1080i display, and picture-improvement circuitry let you view a mix of source signals at high resolutions, up to 1080i. DRC--Digital Reality Creation MultiFunction circuitry--upconverts standard interlaced (480i) video sources to 960i or progressive-scan 480p, while inputs as high-quality as 720p (720 lines, progressively scanned) are upsampled to full 1080i. Because DRC processes video signals in real time, it creates an image with 4 times the density of the original signal. The set's auto 16:9 enhanced mode detects anamorphically encoded widescreen program sources and offers full picture resolution on the video program, wasting none of its usable lines of resolution on the black bars at the top and bottom of the screen.

Guess I will give the Monoprice a go and report back in a couple of weeks. I am using this at my second home, where an lcd or plasma cannot be left over the winter, and I won't be there until Memorial Day.

Hi,
Thanks for your replies. I have an Original Lumagen Vision which has a VGA ( sub H/D15 ) output connector. I want to set that to output at 1080p, then send the 1080p signal to my Mitsubishi HC6500. The HC6500 has a VGA input, but Mitsubishi states that it won't take a 1080p signal. That why I was looking to use one of the HDMI inputs on the projector. Thanks.

Right, but only 720p which gets converted to 1080i. Not 1080p, and if the TV is converting 720p to 1080i you may find the PC doesn't look all that great. Really you'll have to experiment...

Thanks - all I want to do is get the picture from the pc to the tv, so have get vga to hdmi or component. The resolution isn't as important, as long as I have a picture. And I don't need the tv as a monitor, as I will only stream video, so text on web pages just has to be usable, not great (like selecting a movie off Netflix). Experiment it is!

Gottcha. One thing when you experiment, try setting the computer at 720p and 540p. 720p would require the set to downconvert, whereas 540p is the same timings as 1080i and MAY just play as is. Good luck!
