I want to connect my computer to my stock screen. scando 800 wont work because i have hdmi and display port out. Is there something else that works as well as scando 800, and preferably as small that I can get?
View my worklog here
Resizing or downscaling a VGA/HDMI signal using scando or similar is not the best option. The video signal can be generated at the exact res./timing of the factory display using ARM or intel GMA.

Sorry to be rude, but two unbelievable responses? One gives a useless google link as if it's expected a search hasnt been done already...because I just pulled a scando 800 out of mid air smh, and the other a link to youtube with no audio and no desacription of what the product is or where it comes from...double smh. Luckily I see that it has nothing to do with a pc, but for an android...as far as I can tell and find from the limited info that I was able to turn up. Plus it's an overseas product and I dont order anything to be shipped from outside the US.---besides, you really seem to be pushing this product hard on this site like you have a vested interest.
Anyone else care to actually be of some use and help?
I'm sorry if I have not been helpful with your problem. I just wanted to inform about different options.
What model/make of car do you own? As the most of the stock displays, it is probably RGB SCART compliant. So you must search for HDMI to SCART converter. But pay attention in the exact video output, since SCART connector carries CVBS (composite) as well as RGB. Some converters I have seen only supports the CVBS signal in the SCART connector.
Also, the composite sync in SCART is 1Vpp, and the stock displays usually accept 5Vpp csync. In that case you should use a LM1881 IC to "amplify" the sync.
On the other hand, you could use a PC board with Intel GMA chipset with VGA port (http://en.wikipedia.org/wiki/Intel_GMA) and some custom drivers I have made to output the exact RGB SCART timings (with this option you could get rid of the converter, but you will need an XOR gate to merge the sync signals)

You'll find floating around ebay, an inexpensive hdmi to rgb converter - basically a hdmi lead into a plastic box where the VGA port lives. You want the ones that state input/output in both progressive and interlaced. They convert the digital signal from HDMI into the analogue. From what I understand, they convert whatever the signal passes through so no rigid adherence to the VGA standard necessarily - you have to ensure your HDMI output resolution is equivalent to what VGA standard is capable of displaying.
As far as I can see, were your OEM display an RGB type (15.7khz) then it would seem right that were you to input an interlaced resolution (say - 480i) through one of these converters you should be pretty close to the money. If your OEM is a standard VGA (30khz) then send it through progressive.
Don't let they au fool you, the seller is yankee doodle.
Besides that, 480 lines is still not the exact resolution, but anyway better than composite video.
Give it a try, i'm really curious to see if it works.
