I hope this puts an end to the discussion that upscalers are bad:
Also:
Where Vive pro has higher native resolution (1600p native) and Pimax 4k is only 1440p upscaled to 4k.
Pimax 4k is not only much (!) better regarding SDE, but also looks sharper, more pronounced and more detailed. This is what the 8k should have been.
Both pics shot with the exact same SteamVR settings.
Wow. That explains what your talking about. SDE on the upscaled 4k panel looks near perfect
Especially considering the 8K has the new updated CLPL panels it’s disappointing the 8k achieves nothing over 5K. I’ll be waiting to hear results of the 8KX before I consider taking the Pimax option. By that time there will likely be other OLED options on the horizon. 2019 should be an epic year for VR
Difference is really day and night between the Vive Pro and the Pimax 4k. That’s what the difference between the Pimax 5k and the Pimax 8k should have been.
is panel utilization greater on the 4k since it’s only one screen? That could be why it’s so much better than the 8K
Maybe it’s not bad unscaling in 8k. It’s just that no one have the graphics to support it. Or maybe the SDE pattern is just terrible in 8k or the panel is just not good.
Those look like screen shots, not through the lens photos (which probably wouldn’t strangely match the input res of the HMD)… So doesn’t show the upscaling.
Now can you repost using lcd panels for both?
The 4k can look better than the vive pro. 2 subpixels Pentile Oled vs 3 subpixels Rgb lcd.
Like I said we need something like the lenovo lcd wmr headset for proper compare due to sub pixel density.
Just remember the psvr has a nicer sde effect & is reported quite nice with a 1080 ti to drive it. More Sub resolution than Vive & Rift.
RGB needs to be compared to RGB & not Pentile.
Srry that doesn’t sway my opinion 
Like I said we need to compare Rgb with Rgb. I wager the Lenovo wmr lcd headset might look sharper than the 4k & has the subpixels to properly compare.
Rgb has a 1/3 more sub resolution.
It is reported on 1080p depending on a variety of things looks better on a 1080p TV vs a 4k TV upscaling 1080p to 4k. But of course is subjective to the viewer. But technical analysis the native panel looks better than upscaled on a clinical level.
@frc I believe posted a good article of producers/directors irritation of TVs ruining the desired effect with things like TrueMotion.
Well also consider this. The Small FoV in theory has less resolution on the 5k+ vs Vive pro.
We could guess that if main view is 50% that this Res will be 25601440 overall for small FoV mode vs Vive Pro at 28801600. But reports say the SDE is a lot better than Vive Pro?
Why? Vive Pro has a 2/3 of the subpixels
288016002=9,216,000
Vs
256014403=11,059,200
1,843,200 less sub res on Vive Pro.
@Sjef Which picture is which headset?
When comparing I’d like to know which one is which.
For me it is not as clear as for most of the people in this thread.
The left and better looking pic is the Pimax 4K
8K should not be a downgrade to the 4K and too many people have not tried it to know what the 4K was able to achieve.
Hell, I still use old 1.1.92 driver on mine because the quality appears best to me.
In terms of ghosting yes
Same. I use vorpX with 1.1.92 and it looks and performs surprisingly well (maybe because it’s letting steamvr do all the rendering). I haven’t needed to add any SS, since the upscaled 1440p really seams to do a good job.
Instead of SS, I use high resolutions in game (ex: 3200x2400) which seem to downsample to 1440 quite effectively (as you can still see improvements the higher resolution you feed it). Pair this with post process sharpening from vorpX, and I get very clear and detailed image. It even runs slightly faster than on my CV1, but looks much better.
My 4k experience makes me believe we are not seeing the true 8k potential in these tester reviews. Perhaps it’s not more SS that is needed, but simply a sharpening filter to clear up the softness a bit.
I really hope the 8k works comparably well to the 4k, upscale and SDE wise, since this is what gave me faith to back the 8k to begin with.
Brightness as well.
In later Piplay versions when the brightness slider was introduced, it took away the usage of the PiLogger Tool which allowed more options for brightness adjustment.
should be vs
2x ( 2560 ) x1440x3=22,118,400
or
you sholud take vive pro one eye 1600X1400
They’re both through the lens photo’s. Click on them and then zoom in.
