Problema, detecta los HZ de mi monitor pero no se aplica el cambio

[diego_123]

Tengo una grafica Intel b570 Sparkle Guardian OC y cuando intento cambiar de HZ de 74,97 a 100  Hz no funciona y se queda en 74,97, esta conectado por hdmi y el modelo del monitor es Sceptre E225W-19203R.A1 , no es problema ni del monitor ni del cable, la lo probe en un portátil y si funciona por lo que creo que es mas probable que sea problema de los drives de la grafica.

Thank you for posting in our Community. The behavior you’re seeing, Windows detecting the correct refresh rate but failing to apply it, usually points to a bandwidth limitation, driver restriction, or EDID misread specific to the graphics card or HDMI output path. Let’s tighten the scope a bit so we can confirm what’s really blocking the 100 Hz mode. To move forward, may I ask for a few quick details?

• Which HDMI port on the graphics card are you using? Some cards have mixed HDMI revisions, important for bandwidth.
• Do you know the HDMI version supported by your cable? Even if it works on another system, the GPU’s port may require HDMI 2.0 or higher for 1080p 100 Hz.
• Have you tested a different HDMI cable just to rule out intermittent compatibility issues?
• Are you using the latest Intel Arc graphics driver (full installer, not DCH auto-install)? If possible, please share the exact driver version.
• Can you check Custom Resolutions in the Intel Graphics Command Center to see if 1920×1080 @ 100 Hz appears there or if it throws an error?
• Is the monitor connected directly to the GPU, not routed through adapters or splitters?
• Does the Windows “Advanced Display Settings” panel show 100 Hz as a “Supported” mode, or does it list it but not apply it?

Have a nice day!
