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.

To compare the OLED G9’s performance, I have an all-OLED group with refresh rates ranging from 138 to 240 Hz. We have Philips’ 42M2N89 and 34M2C8600, Corsair’s Xeneon Flex, Alienware’s AW3423DWF and Samsung’s OLED G8.

Pixel Response and Input Lag

Click here to read up on our pixel response and input lag testing procedures.

Though the panel response speeds vary from four to eight milliseconds, the visual differences are small. OLED panels refresh the screen differently than LCDs, so they can maintain higher motion resolution at a given rate. At 240 Hz, motion blur is completely absent and there are no artifacts like the black and white trails you often see from LCDs. The OLED G9 also has very low input lag. 24ms puts it among the fastest panels I’ve tested.

Test Takeaway: The OLED G9 exhibits the same smooth play and feel as every OLED I’ve tested. Though there are small differences in overall lag, it’s hard to differentiate OLEDs from one another. They are on a very level plane when it comes to gaming. In other words, there isn’t a bad one in the bunch. The OLED G9 is an excellent gaming monitor thanks to its high motion resolution and low lag. It truly doesn’t get much better.

Viewing Angles

OLED viewing angles are very similar to one another, with almost no visual difference between displays. The OLED G9 maintains brightness at 45 degrees to the sides with a slight shift to red. The top view goes a little cool but also maintains brightness and gamma. The slight color variations are caused by the panel’s polarizing layer. It is much less aggressive than what’s found in an LCD, but it is there, nonetheless.

Screen Uniformity

OLED panels live in the premium price category, so one would expect good quality control. The OLED G9 is no exception, with a respectable 9.46% score. I could not see any variation in brightness or color in any field patterns. Since a zero black level can’t be measured, I used a 10% raster. My G9 sample looked perfect in every way.

    At the current sale price of $1099 this monitor is a very compelling option.

    I think the form factor is just a little to wide for me though.

    Spending this much I would want something that can double as a media display for movies and this monitor and its aspect ratio would just waste too much space.

    " It incorporates Samsung’s TV Plus and Game Hub platforms for seamless access to various streamed content libraries. It delivers shows, movies and games from powerful apps with expansion capability. "

    any chance for a version of this monitor with out that ? maybe for a lower price ?

    A large curved display does not replace having multiple separate displays. Try replacing the a use case of having a game in full screen on one display with system stats, discord, and various other info on a separate display, using just the ultra wide display. At best, you would be hoping the game has a windowed mode that you can drag around and then go through the annoying process of positioning windows and getting a less clean and efficient look.

    theres already reports of other ultrawides like this (not this model ofc) "cracking" towards outer edges as no support for the outer edges and gravity over time is damaging them.

    With picture-in picture or picture-by-picture modes the monitor can act as two independent displays with zero bezel. What you are describing is actually one of the greatest strengths of such a monitor.

    I learned the hard way that the linked version of the OLED G9 on Amazon is not the same as the version reviewed here. It has a different stand and is not Gsync compatible. It only supports Freesync and there is no option to use it with a nvidia graphics card.

    Late to the party, but using the PiP will downgrade the screens to 120hz non-HDR, do not buy this thinking itll perform as painted in the review if you're going to be using PiP

    I'm looking for a wide screen display that supports three virtual screens to match my current loadout of 3 separate 22 inch monitors. It doesn't seem like this model will do that, it only has one mode for a one third / two thirds split?

    Hi
    I am looking for a monitor which I can use split screen and connect my Galaxy Book and MBP simultaneously to this monitor. Will this monitor do that?
