Yeah after reading that you can not cancel your pledge after the campaign ends, I think I won’t back it. Too much risk involved. You basically commit to a delivery in May that might or might not happen at all, or be delayed for god knows how long. What if a competitor with a better alternative joins and you can not cancel your pledge ?
No, the issue is they don’t have a chip that can accept input fast enough for two 4K pictures at 90 Hz. They can do one; putting two of those side by side is one option for the 8K X.
But they just said that for 2 panels they need 2 chips.
The whole issue supposedly is that the bridge chip can not do more than 50 hz. Maybe they tested it that way, with a 50 hz config. But why didnt they just say that then ? It smells fishy. I don’t think they even tested it.
Context. For two of their 90Hz panels, with full resolution and frame rate input, they need two chips currently. This is why the 8K upscales; its input just can’t do it all at the same time. To run two panels with no such comporimise requires two cables, running to separate chips. Theoretically a new signaling format (like DP 1.4 DSC) could also offer another compromise, but we were discussing the no compromise option (as video signal goes; this instead costs and weighs more, with more chips and cables).
Hi Pimax, there is a huge gap between 1440p and 2160p . Previously you mentioned 1 DP port is not able to run native 4k, however, is it possible to give three options on Pimax8K so the native resolution has three modes:
1440p at 90hz
1600p at 75hz
1800p at 60hz
Allow people to switch those modes in Piplay. The above should be technically feasible for one DP port. I think this would be a great option and make it a much more attractive product. What do you think?

Yes, that would solve all the problems of the standard 8K version for me. I’m not sure that the chip they’re using supports intermediate resolutions like that though. I asked once before but didn’t get an answer. @PimaxVR @deletedpimaxrep1, any input on this?
There’s been some mention of sli from your team as viable to drive higher resolutions. Have your team successfully achieve enhanced performance and frame timing using two gpu instead of one?
110 degree fov sucks man I’m tired of looking through binoculars.

Their Kickstarter is now listing prices and they are heavy.
I get all that. But they say 1 chip per panel. So if they can run 1 panel with 1 chip, then they can run 2 chips and 2 panels too.
Thanks. Not sure about heavy though. $699 for the X, seems pretty fair. If they could deliver before May I’d probably back them. Or if I could cancel my pledge between the moment the campaign ends and the delivery.
the max chip input bandwidth is round 23840216050Hz, if drive two 4K panels, each panel refresh rate only around 50Hz. but if drive one 4K panel, 38402160100Hz, the refresh rate could reach 100Hz. So the chipset could drive 4K panel with native resolution (38402160) at 100Hz.

You just described the 8K X.
So you were wrong earlier when you said you needed 2 chips then ? I mean it still doesn’t make any sense. Why not put 2 chips in it and done ?
Yeah so why isn’t that possible then ?
Perhaps, the [Early Bird] 8K X Full Package was what caught my eyes.
Ah yeah I was looking wrong. $749 for the X, whole package indeed, early bird.
if we need handle 8K with 90Hz, that’s 238402160*90, we definitely need two chipsets.
Thanks, but you still didn’t answer whether the existing one chip can handle any intermediate resolutions between 1440P per eye and 4K per eye. Also, can you add the 50hz@ full 4K as an option? It would be useful for desktop and movie use.

So, what is the problem then ? Why not just put 2 chips in it ? I still don’t get it. Then you can drive each panel 4k@100 hz (if the panel could handle it)
