Intel, AMD, and others to phase out VGA by 2015

- InclinedPlane 16y agoDoes $8.33 count as expensive in today's economy? http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10246&cs_id=1024607&p_id=6011&seq=1&format=2 http://www.monoprice.com/products/product.asp?c_id=102&c... Maybe you're just shopping at the wrong places. Many places will charge you an arm and a leg for 6ft of ordinary cat-5 if you give them half a chance.
- listic 16y agoHow easy is it, from electrical standpoint, to convert from HDMI to VGA?
- deleted 16y ago[deleted]
- InclinedPlane 16y agoIt's not possible, there is no such conversion. VGA is an analog signal. HDMI is pure digital. The reason people might be mislead into thinking this is possible is because you can convert VGA to DVI and you can convert DVI to HDMI with nothing more than a simple adapter for each. But there's a problem with this. DVI has two forms: digital DVI (DVI-D) which is signal compatible with HDMI, and analog DVI (DVI-A) which is signal compatible with VGA but not at all compatible with HDMI. Thus in order to convert VGA to HDMI you would need not merely a cable adapter but a converter box.
- aidenn0 16y agoFalse. You can convert from digital to analog: VGA graphics cards do this. You would need a full-fledged signal processor to do this, but I could imagine a box that did this (I could definitely build one myself, but I'm not strong enough in analog electronics to say with confidence that it would work at higher pixel frequencies; I've never done a project with analog signals over 100MHz) [edit] So to answer the grandparent, it is possible; such a box would be expensive (read definitely more than $10, possibly a lot more) though.
- faragon 16y agoCan be done on 10$ (flow shop, >100k units (?)): ASIC or system on chip including three ADC, memory for one row (e.g. 2048*3 bytes) and a PLL clock generator for matching DVI serial port clock. Any electronic engineer in the room for PLA prototype cost estimation?
- zokier 16y agoLuckily the Chinese are already on it: http://www.dealextreme.com/details.dx/sku.37081 http://www.dealextreme.com/details.dx/sku.37081 edit: iirc at least TI had some HDMI receiver chips that are able to output something nice and analog, if you want a more DIY solution. No need for custom chips anyway.
- InclinedPlane 16y agoRead the last sentence of my post. There's no passive way to do it, you need a converter box, as I mentioned. Thanks for paying attention.
- rlpb 16y agoWhat about projectors? Right now, I know that I need nothing more than a VGA connector to walk into any venue with a presentation because the end of a VGA lead will be available. I think it'll take more than five years for this to change.
- aidenn0 16y agoAll projectors I've seen made in the past couple of years will take one of DVI HDMI DisplayPort And DisplayPort can put out HDMI/DVI (The video part of HDMI is DVI) so a simple adapter should allow this. You will have a period of time in which people keep old hardware around to drive other old hardware, but it seems to me that when the bulb dies, just upgrade the damn projector!
- zokier 16y agoafaik basic DisplayPort is not directly compatible with DVI, but the cables are able to carry DVI singal nonetheless. While I'm not very familiar with DP devices, probably most of them currently have Dual-Mode DisplayPort, ie they are able to send either DVI or DisplayPort data.
- asnyder 16y agoI wish this were the case. Most conferences I've been to either don't have a DisplayPort, or DVI, or if they do, they don't have the proper wiring set up, but only VGA. I have to bring a DisplayPort to VGA adapter wherever I go.
- aidenn0 16y agoI'm going to have to upgrade my monitor before then I guess :( I love my 19" CRT. It's already a pain that my macbook can't reliably drive it at 1600x1200 at over 60Hz
- hsmyers 16y agoI suppose this means I have to put my faithful IBM 13inch green screen on the shelf--- <sigh>
