Asus VG278Q Monitor not outputting 120hz on Xbox Series X

Thanks for your reply. Yes I knew about the timings etc, and it does indeed work at 1080p / 120 and 1440p / 60 with HDMI 2.0 on the SX. My point with it working on the PC was that it wasn't a broken monitor

Can't find the original page for monitor compatibility, but here is the ASUS FAQ version for both Xbox and PS5:

https://www.asus.com/support/FAQ/1045097/

The MG278Q is listed in the 1440/120 section in that table.

It is also advertised on the monitor page:

https://www.asus.com/Displays-Desktops/Monitors/Eye-Care/MG278Q/

"Full HD(1920 X 1080)@120Hz output on PS5; Full HD &1440P(2560 x 1440)@120Hz VRR output on Xbox Series X/S"

I've reached out to ASUS tech support as well. I had read that it may be to do with the EDID not containing all the info the Xbox needs, that'll be something for ASUS to answer I think.

Yo, let's discuss

At reddit i found this list of monitors with freesync technology:

• Agon AG251FWG4/AG251FX (30-120Hz)
  
• Agon AG241QX (30-120Hz)
  
• Acer KG271A (48-120Hz)
  
• Agon AG352QCX (30-120hz)
  
• AOC G2460PF (35-120Hz)
  
• AOC G2770PF (35-120Hz)
  
• Acer XG270HU (40-120Hz)
  
• Asus VG278Q (40-120Hz)
  
• Acer ED273A (48-120Hz)

Can anybody say something about it?

I saw Gigabyte AD27QD model and it works best with xonex

Have a good day

The Xbox Series X will do 120Hz but no more, regardless of resolution or monitor.

I would check to see if other Xbox Series X owners have confirmed to achieve 1440p120Hz on those monitors before purchasing.

Maybe a google of "xbox series x 1440p 120hz ___________ " and insert the monitor model to see if people have posted about their monitor and Series X working.

Hello Mega! I'm Claus, an Independent Microsoft Community Consultant for Xbox! Glad to be able to help you!

Given that your monitor only has HDMI 1.4 and DisplayPort, and also given that the Xbox Series X only has an HDMI output, your monitor wouldn't support 1440p at 144Hz. HDMI 1.4 only supports up to 1080p/120Hz or 4K/24Hz.

Until you don't proof me this specific monitor (Xiaomi Mi Curved 34) enables 1440p@120hz with Xbox Series X, your comment is meaningless.

Yeah, there are some monitors with 1440p@120hz support for Xbox series s/x, that simply doesn't mean that ANY 1440p+ monitor with 120hz+ (especially 144hz+) can do it. Period.

I've tried everything, that (1440p@120hz) simply doesn't work with that monitor. I've already listed every step I've tried, I'm not gonna write it again.
