Here are the measurement charts for the VIZIO P65-E1, created using Portrait Displays' Spectracal CalMAN software. These measurements show how close the display gets to our current HDTV standards. For both gray scale and color, a Delta Error under 10 is considered tolerable, under five is considered good, and under three is considered imperceptible to the human eye.

The top charts show the projector's color balance, gamma, and total gray-scale Delta Error, below and after calibration in the Calibrated Dark mode. Ideally, the red, green, and blue lines will be as close together as possible to reflect a neutral color/white balance. We currently use a gamma target of 2.2 for HDTVs and 2.4 for projectors. The bottom charts show where the six color points fall on the Rec 709 triangle, as well as the luminance (brightness) error and total Delta Error for each color point.
Below are the pre-calibration charts for the TV in the Calibrated Dark HDR10 mode, which measured about 480 nits at 100 IRE in a 10 percent window. The top chart is a snapshot of the gray scale, EOTF (aka the new gamma), and luminance. The P65-E1's EOTF tracks just a hint over luminance, and the luminance roll-off is more pronounced than on other TVs I've tested. The bottom chart shows the color performance within the DCI P3 color space, showing the accuracy of all six color points at different saturation levels. The P65-E1 has good color accuracy, with a majority of the color points having a Delta Error at or below 5.0. CalMAN's new Color Volume workflow showed that the VIZIO is capable of 84 percent color volume for the DCI P3 color space.
As I discussed above, the P65-E1 does have a lower peak HDR brightness than many competitors, but in exchange you get a really good, precise black level for a display at this price point. It's up to you to decide which parameter matters more.
In the category of user-friendliness, the P65-E1 doesn't offer a pop-up indicator to confirm when the TV switches into HDR mode. You have to hit the remote's Info button to see if the banner says HDR10 or Dolby Vision. I personally appreciate it when the little HDR or DV icon pops up for a split second on the screen. Also, given what I said earlier about how increasing the backlight messes up the display's EOTF, VIZIO really ought to gray out that control when the monitor is showing HDR content.
Comparison and Competition
From a performance standpoint, I'd argue that LG's newer OLED TVs are the main competitor to the VIZIO P65-E1. Like the VIZIO, they support both Dolby Vision and HDR10, and they are aren't going to crank out the peak HDR brightness that you get in some higher-end LCDs. Unfortunately, you probably won't find a 65-inch OLED for $1,699. Price-wise, LG's Super UHD line of LED/LCDs is a closer match--something like the 65SJ8500 for $1,599. I have not reviewed a Super UHD model, but they are edge-lit panels.
At $1,699, Samsung's UN65MU9000 is the main price competitor to the P65-E1. It supports HDR10 but not Dolby Vision, and it uses edge LED lighting. To be honest, I think that the P65-E1 outperforms the more expensive Samsung QN65Q8C in many respects, so I'm going to guess that it would also outperform the MU9000, which isn't in the flagship QLED line.
Sony's 65-inch XBR-65X850E is an edge-lit panel with frame dimming and HDR10 support for $1,499.
With the P65-E1, VIZIO has done it again--serving up a display that delivers a very high level of performance at a very reasonable price. Plus, the small adjustments that VIZIO has made to SmartCast result in more cohesive smart TV platform and overall user experience.
Over this past year, I've reviewed a couple excellent UHD TVs that cover the price gamut--from the $3,999 Sony XBR-65Z9D at the high end to the $649 TCL 55P607 at the low end. In both price and performance, the $1,699 VIZIO P65-E1 lands in between. It delivers a clear step up in performance from the entry-level TCL in areas like motion resolution, image processing, and bright-room performance (plus the TCL isn't available in a 65-inch screen size), yet the VIZIO can't keep pace with the flagship Sony Z9 Series when it comes to exploiting the full peak brightness potential of HDR. All in all, the P65-E1 is an excellent all-purpose UHD monitor, and you'll be hard pressed to find a better performer around its price point.
