Is 1440p@240hz HDR possible with DP 1.4a?

The title is the question. Why I'm asking is because Samsung's upcoming Odyssey monitor (G7) can run 1440p resolution at 240hz (HDR 600 supported). I don't want to bother with chroma subsampling because I find it very distracting.

I used Glenwing's calculator and got these results for 8 bit (Can't take 8bit + FRC on this calculator, and 10bit is 30.77 Gbit/s)

 

Data Rate Required: 24.62 Gbit/s

Video Format:
2560 × 1440 (16∶9 ratio) at 240 Hz
8 bpc (24 bit/px) RGB color
Uncompressed
CVT-R2 timing format

 

While I'm at it does 8bit + FRC add extra bandwidth to Displayport 1.4 compared to just using 8 bit? I want to know because I'm interested in HDR gaming and don't want to deal with chroma subsampling in the future when graphics card can do 1440p@240hz w/ HDR.

The maximum limit of each interface is in a table on the left hand side of the calculator. The maximum data rate of DP 1.4 is 25.92 Gbit/s. So 8-bit would be possible, 10-bit would be outside the limit.

 

8-bit + FRC is a 10-bit signal in transmission, so it does use the same bandwidth as a native 10-bit panel would.

Hmm ok. I will check the review when the monitor comes out. Otherwise, I can just wait for a refresh/newer version with HDMI 2.1/DP 2.0. 

Thanks!

The actual 10-bit will usually be with 4K though, with lower refresh rate.

4K 240Hz 10-bit HDR will be amazing to eventually see.
