Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Uncalibrated – Maximum Backlight Level 

We’ve rounded up a group of 1,000-nit monitors for comparison to the ROG Swift PG43UQ. We have the Acer Predator CG437K, Acer Predator X35, Acer Predator X27, Acer ConceptD CP7271K and Asus ROG Swift PG27UQ. Panels are a mix of VA and IPS with both full-array local dimming (FALD) and edge backlights. Every monitor has extended color, Adaptive-Sync and a fast refresh rate. 

Asus rates the ROG Swift PG43UQ at 750 nits for SDR, but our sample clocked in at just over 878. That is some serious light output; enough so that you can’t look at a full white field directly. Dynamic Dimming reduces that a bit to 830 nits.

The real benefit to the PG43UQ dynamic contrast feature is its effect on black levels. Turning it on reduced the black value from 0.1939 to just 0.0745 nit. That’s almost OLED black and resulted in an SDR contrast ratio of 11,142.2:1. Without Dynamic Dimming, the PG43UQ turned in a superb 4,528.1:1 native contrast ratio. That’s better than almost every monitor we’ve ever reviewed.

After Calibration to 200 nits 

Setting the ROG Swift PG43UQ to 200 nits meant dialing down the brightness slider to level 5 of 100. Minimum brightness is 165 nits, so users in completely dark rooms will be playing on a very bright screen. That comes down to personal preference, but we find such a high minimum fatiguing after a while. Contrast remained impressive after our calibration at 4,314.1:1. 

The PG43UQ also demonstrated excellent intra-image contrast with a score of 4,310.6:1 in the ANSI test. Our checkerboard pattern showed no change with Dynamic Dimming, but it certainly improved image quality for all real-world content.

    Extremely tempting but price needs to go (way) down and GPU power up for such awesomeness to be readily adopted.

    Seems that TV manufacturers are missing an opportunity. TCL sells a 43" 4k tv for about $200. You can't tell me that it costs 9X more to make a 144hz 43" tv. Asus sells it for that much because there aren't any mainstream options. TV companies see the 43" TV size as a low end product whereas it's a high end price point for PCs.

    VA / W-LED, edge array for $1500 when TVs of this size can be had for $300-$400?

    You can get the XG438Q now for like $1000 why get this?

    Looks awesome and probably something I would have bought had I not recently purchased the LG CX 48 inch TV as a gaming display. As someone who uses a large display with my pc I would say the size isn’t much of an issue and after a while even the 48” screen stops looking too big. I’m currently looking for a good deal on a lap board for the keyboard and mouse, there aren’t too many on the market at the moment even though these large displays are creating a need for them.

    How do you think this monitor might be better than your CX? I thought the CX was a shoo-in for best gaming display with with the OLED screen, g-sync, 120hz, but I would love to understand where this Asus monitor compares favorably.

    I do alot of drone racing. Its critical to have a fast video feed from our drones to our goggles otherwise we wont have enough time to react and crash into everything. We deal in millaseconds delays also. With that said 1ms response time vs previous version of this monitor 4ms you will tell the difference when gaming. Im not sure if there is any monitor this size with these stats with freestink.

    is this not 144hz compatible with gsync?
