Need Help. Resolution on 4k screen.Solved (sort of)

post #1 of 12
Thread Starter 
Finally my loooong awaited projector, Sony's VPL-VW1000ES, first 4k consumer projector, has arrived. Took way longer then i expected and cost more too... (25k euro) for those whi have been living under a rock tongue.gif 4k is 4096x2160 resolution said to replace 1080p eventually.

So i hook it up to my quad 7970s and the resolution above 1080p is not selectable.. I'm like FUUUUUUUUUUUUUUUU...
Can someone help me find a solution maybe force custom resolution or something? I am using the required 4k capable hdmi cable hooked up to my 7970 via hdmi output (worth switching outputs?)

Otherwise the product is great. Movies or games alike benefit from this nifty feature called reality creation. Basically it upscales 1080p content to 4k by increasing pixel count, and you can absoluteley tell the difference. For example text in windows desktop was blurry with the feature turned off up close, but gained alot of definition with the function On. O had anither projector before, and even 1080p upscaled is waaaaay better, now i want to get real 4k res. (it maxes out at 24Hz to my greatest disappointment though, due to hdmi limitations).

For anyoune wonering, the difference in quality is huge. Maybe not 25x the price of an entry level projector "huge", but you can unmistakeably tell.

Thx in advance


Update: resolution selectable now, in it is awesome, i could nit ask for more. A sreen nearly 3 meters wide 3 meters away from me, the picture quality and contrast are perfect! Just wow! Skyrim in full settings is unreal, but the area load times trippled...

Hi,

you only hooked up your sony projector to your pc or is there also an lcd-screen? If so - try to set the projector to be the main-output-source (at the menue for the screen settings, the projector should be set to display=1)

Maybe switching to Display-Port would also help.

And keep the drivers up to date - also important.

I found a german site testing the vpl with an Radeon 7970. They claimed that they hooked up the projector and instantly got an perfect picture in native 4k.

otherwise contact AMD directly

Thank you for your answer. Y, i have hooked it up directly, and only 1 monitor is atattched. I did see a review with 7970 being direcktlyhooked up and dont understand why it just wont work. I have also hooked it up to my alienware lapto with dual 6970s and the result was the same.
So far i tried 12.4 and 12.8 catalyst..
Alsomy driver i stallation seems corrupt because sound output is choppy. Or is it something else?

4k?probably a tv thing,anyway on this end you ll need display port nothing else is powerfull enough and probably only a very recent dp standard,what people say computer user are about to get is quad hd,or 3840x2160x46 inch (for exemple)since tv love to have a different standard then computer (probably to lower piracy)your 4k is probably a hdtv thing!

Hm. You could go to the drivers, untick the "show only supported modes" and see if you can find the resolution @ 24Hz in the full list. Failing that you can sort of enforce unsupported resolutions on attached screens though the EDID hack (creating your custom profile) although I have no experience on trying to do so on HDMI port as I dont use HDMI.

You mentioned that the cable is 1.4a ? Right ? So it should not be an cable issue. Is the legth also within specifications ? I'm not sure from top of my head but is it limited to max 2 meters with HDMI as well for sufficient bandwidth ? I know that DisplayPort is limited to max 2 m (on paper) for max bandwidth, although in my experience good quality cables have no problems doing 3 - 4 m without major issues.

3840x2160 @30 seems to play 4k videos on youtube (but they are nit really 4k apparently)? But when i switch to 24Hz 4096 i get jus a black screen.on a side note, S#\t never looked so real! I love it!
Ps: for the moment both resolutions are called 4k, but eventually only 1 will be accepted as "standart"

Gonna try me some Skyrim now smile.gif
