It's a somewhat confusing situation.
The FS Dom V2's have a published max resolution of 600 x 480
The FS Dom HD's have a published max resolution of 800 x 600 which is the same output as the DJI Inspire 1 and P3 HDMI boards. (This is not true HD resolution, and is where the real confusion begins...)
The Dom HD's are not ture HD as they can not support 720p or 1080p resolution. However, the "HD" term has stuck with the goggles.
Likewise, though the Dom V2's have an HDMI input they are limited to VGA resolution and can not down convert from the output of the DJI HDMI board. The idea behind offering an HDMI input on the Dom V2's was to support some gaming devices.
The only true HD goggles that I know of are the Zeiss Cinemizer OLED goggles and the Range Video HeadPlays. There is a new HeadPlay type HD goggle now coming out of Russia called the eYebox, but I have only seen photos.
Soooo...the Dom V2's won't workin their stock configuration. An outboard down converter might be an option but I have not heard on on in successful use so far. The Dom HD's are discontinued though still available at a discount for about $550.00, the HEadPlay are slowly being shipped with about a 60 day delivery window. The HeadPlays cost $250 and include an integrated 32 channel 5.8 gHz video Rx. The HeadPlays use a small HD video monitor instead of two individual led screens. The visual effect is more cinematic than immersive.
My HP's should be here by Monday and I'll post my initial impressions. If they don't do it for me I'm going to buy a pair of Dom HD's.
