Sony VPL-VW1100ES vs NVidia GTX970

My EVGA GTX970 won't sync with My Sony 1100ES projector in 4K/2160p mode !

I just install NVidia GTX970 Graphic Card (EVGA 04G-P4-1970-KR GTX970 4GB) into my Windows7 64bit Intel i7 HTPC recently.

HT Connection Route:
HTPC --> DENON AVR-4520 --> SONY VPL-VW1100ES (4K projector).
All via HDMI cables.

Resolution:
With 1080p resolution all work fine.
But when I switch GTX970 to 2160p 60fps resolution the whole image went viral/messy (attached photo), it is fleshing on and off, like whole system try to sync but failed.
The Sony 1100 making mechanical noises as it move the lens device (?) back and fort.
Switch back to 1080p, image is OK.

Why and how to fix this ?

I wondered if anyone was going to try this.
Try setting your NVIDIA card to output at 60fps at 2160p in the NVIDIA control panel of course.
If not try 24 at 2160p or 23 (23.976) at 2160p.

If it still doesn't work try connecting the projector directly to the HTPC.
With out checking I think that your Denon may not like dealing with the 2160p resolution.

Edit:
Just checked the specs and it your Denon has 4K pass-through, but I would still bypass the AVR just to remove that part of the equation, if need be.

That NVIDIA card is also not HDCP 2.2 enabled, that also may be a factor.
The only one that I know off that is, is the GTX 960.

If that is the problem, the I will be in the same boat with my GTX 980 _ if it ever comes to that.
If that is the problem, at least the 960 is inexpensive at around 200.00 bucks.

If I pass through Denon ( GTX970 --> Sony 1100ES), how can I get the digital audio, GTX970 do not has Optical Audio Out?

Yes, that's another problem.
I was just having you bypass the Denon AVR at this point just to see if it cured your original problem.
If it did, then at least you will know what is causing the scrambled picture and the problem is with the AVR.

Just had another thought too and some here will also chime in on this, I'm sure.
Are your HDMI cables 2160p enabled, assuming that is even a factor.

There is lots of discussion over this and that is if I am using HDMI 1.4 cables, will they work for HDMI 2 and/or pass a 2160p resolution.
Some say yes and others say no.

Your motherboard doesn't have SPDIF optical out?

Hi Jeff,
Thanks for your inputs.
As your suggestion I switch the resolution to 2160P with 30 fps and it work, I got the 2160p resolution via Denon.
Why it will not work with 60 fps?

Now I have another problem, my Windows display/characters now become very small/tinny !

That's one drawback of using such a high resolution. On the same size screen pixel density has quadrupled which means everything will be four times smaller. A simple solution would be to turn on UI and text scaling inside Windows.

Is your HTPC outputting the 2160p in RGB mode or YCbCr (component) mode via HDMI? If in RGB mode the VW1100es can only handle 30Hz max. for the refresh rate. When in YCbCr mode the VW1100es can handle 2160p @ 60Hz, but only if the chroma is at the lower resolution 4:2:0 mode (but only at 30Hz max. when the chroma is in 4:4:4 mode). This is the limitation of the HDMI 2.0 chips that only support 10.2 Gbps data rate, including those used in the VW1100 as well as AVRs, at least up until a very few full bandwidth HDMI 2.0 equipped AVRs models were recently released.

Do you have the latest drivers?

2160p is 4 x 1080p resolution also meaning 4 x headaches !

Come on now, don't get angry, I wish I had an 1100es to play with my HTPC.
Remember too that you're trying to do something here that isn't done very much and you're possibly the first one _ the first one to post anyway.
There are bound to be some snags you're going to run into.

I set to 200% still too small to my taste/aging eyes . . . .

Well if you're at 200%, then you must have found the custom settings.
Go as large as necessary until you find a settings that works.
What ever player you're using (maybe Cyberlink Power DVD), it should over-ride the Windows settings so when you play a movie, it should look normal.

I use PowerDVD 15 Ultra. Thanks again Jeff.

Exactly. For a start 2160p60 can only work from your 970 to the VW1100 if the 970 outputs YCbCr 4:2:0, and I'm not sure if the 970 can do that. And then your Denon must be able to accept 2160p60 4:2:0 and pass it through as 2160p60 4:2:0 to your VW1100, too. So the issue can be the 970 output, or the Denon passthrough. Of course it could also be the VW1100 not liking the specific timings used by either the 970 or the Denon. It's a good idea to take the Denon out of the loop, just as a test to identify whether the Denon might cause the issue or not.

It's sad that the VW1100 doesn't have 18Gbps chips, otherwise things would have been so much easier.

Not a problem for my HTPC since I run everything through JRiver MC20 (and MadVR). It has options to switch display settings based on source, so my desktop is always 1080p for easy reading and most movies are displayed at 4K (or UHD). I highly recommend this software and it's probably the best audiophile software for HTPC too. And it doesn't break the band either.
