USB to hdmi converter display problem
I just recently bought a usb to hdmi converter as i had a laptop and it didnt have an hdmi port,i installed all the drivers that came along with the cd packed in it,i even got it to work but there still exists a problem.
Before i had a vga to vga cable,my laptop didnt support 1080p but my TV did so thats y i had to change the display to projector only mode to watch 1080p video,but as the quality wasnt good i decided to buy a usb to hdmi converter.
Now when i connect the usb to hdmi converter to my TV,its working in mirror as well as duplicate mode,but not in projector only mode.As my laptop only supports 720p i can watch videos on my TV only in 720p resolution and not in 1080p.When i click projector only mode it blanks out for a while and then it says "No projector detected".Even when i click detect its not being detected.
Windows 7 Home premium
Mobile Intel(R) 4 Series chipset family
I really would appreciate any kind of help cuz i bought the converter only to watch a perfect 1080p video.
Thank u for ur time.

If the laptop only supports 720p a standard USB to HDMI cable won't give you anything more than the laptop supports. You'd need an expensiver upscaler etc. (Unless I'm missing something?)
As my laptop only supports 720p i can watch videos on my TV only in 720p resolution and not in 1080p
In that sense it's no different to plugging a super high monitor into the computer, it still can only output what is available in the first place. And not all USB2HDMI support 1080p as standard anyway, a lot are 720 max.
In terms of the projector not working standalone, most of the "cable" based graphics are actually software driven mirrored drivers of your actual card. Without using the built in card etc there isn't much to output (at least how I understand it).
If all you're after is 1080p on a TV, wouldn't it be easier to buy a standalone media upscaler just to plug straight into TV and use without laptop?

Okay let me make this clear..

Wont standalone media upscalers still be very costly compared to usb to hdmi adapter?My hdmi converter is max 1080p which i know for sure.
I can also set the resolution of extended display to 1080p,in which i can do everything except watching videos(Videos just remain still or blank on the extended display)
