GPU × monitor display-signal compatibility

Will this exact GPU and monitor run the display mode you want?

Pick your graphics card and monitor, choose a resolution, refresh rate, colour depth, HDR and VRR - get a per-connector verdict with the evidence behind it.

Not an FPS calculator. It answers one question: will this display signal actually go down the cable?

Only the graphics card and monitor are required. Everything else has a safe default.

Graphics card

Pick your exact model. Short names work too (e.g. 4070S,1080 Ti). Not sure which SUPER/Ti you have? Check GPU-Z.

Monitor

Include the trailing letters (e.g. 27GR93U-B). Model codes, SKUs and nicknames like Neo G8 work.

Display mode you want

Resolution

Refresh rate

In Hz - the number on the box (e.g. 144, 240).

Colour depth

Not sure? Leave on Auto.

Connection

I want HDR I want VRR (G-SYNC / FreeSync)

What it checks

ResolutionRefresh rateBit depth (8 / 10-bit)HDRVRR (G-SYNC / FreeSync)HDMI vs DisplayPortWhether DSC is needed

Verdicts are per mode and per connector: the same pair can beSUPPORTED at 4K 120Hz over HDMI and NOT SUPPORTED at 4K 240Hz 10-bit over the same port.

What an answer looks like

Yes - use DisplayPort. The mode fits without compression on DP; HDMI on this monitor tops out lower.
Yes - but DisplayPort and DSC are required. The uncompressed link isn't wide enough; DSC closes the gap and both ends support it.
Not supported. 240Hz isn't available on this connection. 144Hz is.
Unknown. We couldn't verify the card's link rate from any official source. 120Hz is confirmed and safe.

Why a result can be UNKNOWN

Some GPUs - several AMD cards in particular - don't publish their DSC support or exact link grade anywhere official. We won't guess a spec to remove an UNKNOWN. Every UNKNOWN result still tells you what isconfirmed and the closest mode you can rely on.

FAQ

Is this a gaming FPS calculator?

No. It checks whether a display signal can be transmitted, not how many frames your GPU can render.

Does it guarantee my setup will work?

No. It reflects verified specifications and reported issues. Cables, firmware and drivers can still matter - see each result's "Known issues" and Terms & Disclaimer.

Why is my exact GPU or monitor missing?

The catalogue is a small, hand-verified pilot set. It grows as data is verified - we don't bulk-import unverified specs.
