你可以说对纱窗效应不敏感，说看不到就是胡扯了，我玩vive pro的，只要是有纯色显示的地方还是有很明显的 ...

pro差index和8kx差不多两个档呢

老哥这就是你不懂了 vive pro用的仍然是AMOLED 虽然有600PPI 但因为AMOLED的晶体排列问题，分辨率一致的情况下其纱窗效应相当强  观感上仅仅是INDEX那种LCD屏的400PPI.... 差了INDEX整整1/3....

我整个表都拉给你 你做个对比 可以看到600PPI的头显但凡是采用了pentile晶格排列屏幕的，都会被降格到400PPI左右以符合实际观感。

PCVR HMDs ranked most to least SDE by PPI:

9. Pimax 5K XR

Pixel density - Pimax 5K XR

5K XR 2560 × 1440 / 5.5in (diagonal of screen) = 534 PPI (in the rendered part of the screen)

(Effective ppi of the 5K XR) is 5K XR PPI /3 x 2 because pentile subpixel arrangement, 356 PPI).

Due to the fact the screen only renders 3/4 of the images, they must be magnified by 1/4, 356 is divided by 100 and multiplied by 75 to make a final result of 267PPI for the 5K XR.

Rendered subpixels - Pimax 5K XR

5K XR (2560 x 1440) x 2 (OLED Pentile) = 7,372,800 subpixels per eye.

Same as the 5k+, divide the result by 100 and multiply by 75 or 80 to take into account for panel utilization

= 5,529,600 - 5,898,240 visible subpixels per eye on the 5K XR.

8. Vive Pro

Pixel Density - Vive Pro

1600×1440 / 3.5in (diagonal of screen) = 607 PPI

(Actual ppi is /3 x 2 because pentile subpixel arrangement for a final value of 404 PPI).

Rendered subpixels - Vive Pro

(1600x1440) x2) (OLED Pentile) 4,608,000 subpixels per eye.

7. Samsung Oddessey+ (Anti SDE)

Pixel Density - Samsung Oddessey+

1600×1440 / 3.5in (diagonal of screen) = 607 PPI

(Actual ppi is /3 x 2 because pentile subpixel arrangement for a final value of 404 PPI).

Rendered subpixels - Samsung Oddessey+

(1600x1440) x2) (OLED Pentile) 4,608,000 subpixels per eye.

6. Pimax 5K+

Pixel density - Pimax 5k+

Pimax 5k+ 2560 × 1440 / 5.5in (diagonal of screen) = 534 PPI (in the rendered part of the screen, which is a magnified 534 PPI.)

Due to the fact the screen only renders 3/4 of the images, they must be magnified by 1/4, 534 is divided by 100 and multiplied by 75 to make a final result of approx. 400PPI. This is why the Pimax has the same unmagnified PPI as XTAL, but more SDE.

Rendered subpixels - Pimax 5k+

RGB LCD has three discrete subpixels per pixel, or ((2560x1440) x3) per eye, or 11,059,200 subpixels per eye.

However ; due to the lack of complete panel utilization (seen in the above video and teardown) the final result 11,059,200 needs to be ÷100 x 75 or 80 to accomodate for the fact that only 3/4 of the panel is rendered to on pimax headsets, the lenses magnify the image and only the lenses move during IPD correction and the screens remain fixed in Pimax headsets, the software only renders to half the available screen and keeps. the rendered image in line with the lens position.

Final 5k+ rendered subpixel = approx 8,294,400 - 8,847,360 visible subpixels per eye

5. 8KX

Pixel Density - Pimax 8K/8KX

Pimax 8K / 8K X (3,840×2,160 / 5.5 = 801 PPI )

801 PPI Magnified... /100 ×75 Also approx. 600 PPI.

Rendered subpixels - Pimax 8K/ 8KX

8K (3840×2160) ×2) (Pentile LCD ) = 16,588,800 subpixels per eye

Same as the 5k+, divide the result by 100 x 75 or 80 to take into account for panel utilization

12,441,600 - 13,271,040 possible visible subpixels per eye with native 4k input on 8K X using 8K screens.

4. StarVR One

Pixel Density - StarVR One

(1,830 × 1,464 / 5.5 diag = 426 PPI)

Rendered Subpixels - StarVR One

AMOLED RGB has three discrete subpixels per pixel, or ((1830x1464) x3) per eye, or 8,037,360 subpixels per eye.

3. XTAL

Pixel Density - XTAL

(2560x1440 ) / 5.5in diag )= 534 PPI.

Rendered Subpixels - XTAL

OLED RGB has three discrete subpixels per pixel, or ((2560x1440) x3) per eye, or 11,059,200 subpixels per eye.

2. Valve Index

Pixel density - Valve Index

Valve Index - 1600×1440 / 3.6in (diagonal of screen) = 598 PPI

Rendered subpixels - Valve Index

RGB has three discrete subpixels per pixel, or ((1600x1440) x3) per eye, or
6,912,000 subpixels per eye.

1. HP REVERB & Acer ConceptD OJO

Pixel density - Reverb & Concept D

(2160 x 2160) / 2.89in )= 1057 PPI.

Rendered Subpixels - Reverb & Concept D

LCD RGB has three discrete subpixels per pixel, or ((2160x2160) x3) per eye, or 13,996,800 subpixels per eye.

好的，谢谢，那我得换个头盔了
