OLED has taken this category completely — all ten monitors here use it, all ten have a 0.03 ms response time, and nine of the ten cover 98.5% or more of DCI-P3. The specifications that used to separate gaming monitors have converged.
What separates them now is shape, and what the monitor does when it is not gaming: USB-C power delivery and a KVM switch turn a monitor into a docking station, and half this list has them.
Every figure below is the live computed Mars Score.
Highest score in the catalog: Samsung Odyssey OLED G9 (G93SC)
Mars Score 85.6 at $1,599. A 49" 32:9 curved QD-OLED at 5K and 240 Hz, with USB-C at 65 W and a KVM.
It is two 27" 1440p monitors fused into one panel, and that is either exactly what you want or completely wrong for you. No G-Sync certification and a single HDMI port are its gaps.
Best ultrawide: LG UltraGear 45GX950A-B
Mars Score 81.4 at $1,699 — the most expensive monitor here. 45" 21:9 at 5K and 165 Hz, 1,300 nits, 90 W USB-C, KVM, both G-Sync and FreeSync.
21:9 is the ultrawide shape most people actually get along with. The ASUS ROG Swift PG39WCDM (78.3, $1,499) is the 39" 21:9 alternative at 240 Hz rather than 165, at 1440p rather than 5K — faster panel, less resolution.
The 32" 4K group — three prices for one specification
MSI MPG 321URX (78.2, $1,099), Gigabyte AORUS FO32U2P (78.2, $1,299) and Samsung Odyssey OLED G8 (78.2, $1,299) all score 78.2. All are 32" flat 4K QD-OLED at 240 Hz, 1,000 nits, 99% DCI-P3.
What actually differs:
| USB-C PD | KVM | DisplayPort | G-Sync | Price | |
|---|---|---|---|---|---|
| MSI MPG 321URX | 98 W | yes | 1 | yes | $1,099 |
| Gigabyte FO32U2P | 65 W | yes | 2 | yes | $1,299 |
| Samsung Odyssey G8 | none | no | 1 | no | $1,299 |
The MSI is $200 cheaper, charges a laptop fastest and has everything the Gigabyte has except a second DisplayPort. The Samsung costs the same as the Gigabyte and has no USB-C, no KVM and no G-Sync — it is the one to avoid in this group, and the score cannot tell you that because those three features are worth few points each.
Best console monitor: Dell Alienware AW3225QF
Mars Score 78.1 at $1,199. 31.6" curved 4K QD-OLED at 240 Hz with two HDMI ports — no USB-C, no KVM. If it sits in front of a PlayStation and a PC rather than a laptop, none of that matters.
The fastest panel made: LG UltraGear 27GX790A-B
Mars Score 77.6 at $999. 480 Hz — double almost everything else on this page — at 26.5" 1440p, 1,300 nits, 65 W USB-C.
480 Hz is for competitive shooters and nothing else. If that is what you play, no other monitor here is relevant; if it is not, you are paying for frames your eyes and your GPU will not produce.
Best value: MSI MPG 271QRX
Mars Score 76.9 at $899. 27" 1440p QD-OLED at 360 Hz, 98 W USB-C, KVM, G-Sync — the full feature set, at the lowest price on this page.
The Samsung Odyssey OLED G6 is the same score at the same $899 with the same panel, and again no USB-C, no KVM, no G-Sync. The comparison repeats itself, and the answer is the same.
Who should buy the MSI: most people. 27" 1440p at 360 Hz is the sweet spot of this category, and it docks a laptop with one cable.
How to choose, in four questions
- Shape first. 32:9, 21:9 and 16:9 are three different desks. Nothing else matters until that is settled.
- Will a laptop plug into it? USB-C power delivery and a KVM are what separate identically-specified monitors here, and they are worth more day-to-day than 100 Hz.
- Refresh rate above 240 Hz is a competitive-shooter feature. For everything else it is invisible.
- Check ports. One HDMI and one DisplayPort is limiting the moment you add a console.
