ASUS OLED PG42UQ V40 Firmware Best HDR & SDR Settings Guide

The new ASUS Rog Swift PG42UQ OLED firmware is out, V40 (aka Version 40). So far, I think this is the best iteration of the firmware.

PG42UQ V040 HDR Performance Results

I haven’t had any weird black screens like a lot of us were experiencing with V037. Color reproduction in HDR is much better than V037 & V033, but it isn’t perfect. Colors are deeper and richer than before but still require an increase in vibrance. I do feel the brightness has gone down a little bit, but it isn’t that noticeable.

Color Tones are Still Off

My first problem with V40 (and with previous firmware versions), are the surplus of red tones/lack of blue tones. Whites look too beige due to too much red tones being present. I am not sure why ASUS likes the warm tone so much, to me it doesn’t look good. Looks even worse if you are wearing protective blue-light eye gear…

Color Saturation Better but, Still Needs Adjustment

Second, color saturation is still low. Don’t get me wrong, it is much better than any other PG42UQ firmware version, but it still misses the mark and, could use an increase of roughly 21%. I can’t help but wonder how the color adjustment process works when ASUS is creating drivers. I am planning to reach out to them, so I will keep you posted on that.

Guide to Improve PG42UQ HDR Setting

Fortunately, there is a fix for the two issues above. While we all wish we didn’t have to make adjustments to our PG42UQs, I feel it is an acceptable trade-off to have to not switch between SDR and HDR modes. This is especially true if you are using NVIDIA Surround, since color space & refresh rates can be affected when switching between HDR and SDR. Far more annoying to check settings refresh rates and settings every time than, to put 10-15 mins into the settings below; and then 1-5 mins every time NVIDIA drops a new GPU driver. (Sorry to AMD users, I don’t have another system for testing with AMD card, yet.)

Best PG42UQ HDR & SDR Settings Firmware V40

If you want to get the best colors out of your PG42UQ, I suggest you follow the guide below. It will correct the beige-whites and enhance color saturations issues. But before we get to that part, you need to make sure all other settings are configured correctly. If you have completed some of the steps below, you can skip them, but I highly recommend you complete them in the order (With exception to Installing the Display Driver.).

Step 1: Update Your PG42UQ to Firmware V40

Download PG42UQ Firmware V40 here (USA Site)
Follow the instructions on how to install the PG42UQ firmware here. (Skip “step 3” on the linked page, since you already downloaded V40). For the rest of the guide on the linked page, replace “V033” with “V40”. After you complete the firmware update, come back to this guide and move onto the next step.
- **IMPORTANT** Be sure to precisely follow the firmware update instructions. Mistakes here could result in the firmware installing incorrectly and is attributed to “false positive” installations and poor monitor operation.

NVIDIA Control Panel Digital Vibrance & Color Adjustment

Step 5 (LAST STEP): Adjust Color & Color Saturation in NVIDIA Control Panel for ASUS PG42UQ OLED V40 Firmware

Use the instructions on the linked page to navigate the NVIDIA Control Panel for the best HDR settings for PG42UQ. Before proceeding, please make sure you are using the correct values for NVIDIA Control Panel.
- Replace the values on the linked page with the values BELOW.
- The values below are broken up into NVIDIA Driver Versions. Make sure you use values that corresponding to your NVIDIA Driver Version. (Sorry Team Red, hope to have settings in the future)
- The color correction values below are for Firmware V40 ONLY.
- IMPORTANT: If you plan to frequently switch between SDR and HDR, I recommend using the Recommended Vibrance setting or lower. This will prevent your SDR content from being oversaturated.

I knew it that I can find the latest update here!
Thanks for your effort.
I’m gonna try V040 firmware.

BTW, I have a question about installing the PG42UQ display driver.
If I enable Nvidia surround, do I need to install the driver again? Or I just install driver for each monitor seperately?

  Glad you thought of WiredColony :D. So to answer your question, you don’t need to reinstall the display driver. It should already be using it before Nvidia Surround. Also, the saturation appears to have changed over a bit of time. I think it is back to V037 levels of saturation but, no black screens. Nonetheless, definitely worth using V40.
