A: For the monitor to automatically perform the OLED Panel Refresh pixel cleaning the following settings must be true. Why this isn't part of the manual, or warned on the monitors menu is beyond me. You must use these settings if you don't want to be interrupted by OLED warnings/cleanings while you are busy!!! Power Button -> "OFF" USB C Powed -> "OFF" Recommended setting for quality of life (not required) Protect Notice -> 16 hrs. The above settings will make it so the monitor performs OLED cleaning once 4hrs of use is true and the monitor is inactive for the specified time during in the monitors settings. I googled "MSI Panel Protect Reddit" and went through tons of complaints before finding the above solution. I've updated my monitor's firmware and am running FW.017 for reference. Also for reference in the newer firmware, MSI fixed the issue where the monitor would power off after OLED cleaning. So if your monitor is powering down on you forcing you to manually power it back on, you can fix this by updating your monitor's firmware. Aside from this OLED issue that is resolved by tweaking settings, the MSI MPG 491CQP is definitely the best OLED monitor I've used between Samsung, LG, MSI, and Gigabyte. Especially for out of the box picture and gaming features.

I was in the market for an ultrawide monitor for a longtime, and did purchase with another brand. However, due to some QC problems, had to return and began my hunt again. I had (and still currently do, top 2 monitors in photo) MSI monitors before and they have never let me down in terms of quality and durability (survived 3 moves and a little knocking around, they're still going flawlessly), so when I heard MSI was releasing a new lineup with a 49", I was already sold, it was just a matter of getting one when it was available. I was going to buy two (essentially replace out my top monitors), but after my first set from a different brand ruining that experience, I held off. Currently beating myself up for not now after unboxing this and getting it plugged in. For the price, alone, I am blown away from picture quality. I think it's comparable with its competitors, but has the edge given the base pricing (not to mention more dedicated experience in the gaming space versus others). It does have an automatic pixel refresh (since OLED) and I have it set to where when the monitor goes into standby or shuts down is when it will do the refresh automatically; it is initially set for every 4 hours of use up to 16 hours. If I had to given any major critiques, it would be the outer packaging; everything inside was packaged great for the most part; the screen, itself, did not have a plastic protector on the front of it like the other set I had purchased (but seeing that as a MSI standard as my previous ones arrived the same way), but everything worked as should. Outside packaging, the box looked discolored, more pink than red as if it sat in sunlight. Although I cannot attest this is how packaging was purposefully made, made me curious why that transition. One corner of the box was pushed in, but the monitor was encased with styrofoam so zero damage to the monitor at all (this was, likely, out of distributors control and more so deliverer). As of now, we're sitting at a 5/5 for rating solely for the base pricing, this gives this monitor some edge for those wanting to upgrade into the ultrawide monitors as well as OLED. Only time will truly tell how well this monitor will hold up!

Wow! So bright! This is the first QD-OLED where I don't have the SDR brightness maxed. HDR is phenomenal. The color is so good, I wasn't sure it was on. MSI gives you a choice of True Black 400 or max 1000 nits. I haven't seen that in any other monitor. I don't think a picture can do justice to how rich the colors appear. If you have anything less than an RTX5080 I think 144hz (which means 144 FPS in games) should be fine. It is also very nice that it has a Rgb mode and Premium Color. Also a 3 year burn in warranty and maybe the best OLED care out there.

I was worried about getting an ultrawide, especially a 49" one but I had a friend who recommended it. I was very excited at the prospect of a QD-OLED and thought I'd give it a go. I will never be able to game on anything but a huge ultrawide monitor ever again, its level of immersion can not be matched by a regular monitor. The Panel is gorgeous and the HDR content in games is absolutely incredible, I've been setting to 1,000 HDR for maximum brightness but even the true black 400 HDR looks stunning. I strongly recommend this monitor for anyone who has the space.
