U2518D, M2T104 firmware fixes, CVR timing?

In the User Guide for the U2518D, in Preset Modes, it specifies CVR for native resolution as opposed to VESA timing. What is CVR timing? One of the forms of reduced blanking? Additionally, can any information be secured on what M2T104 firmware fixes? Pending purchase but no go until there is evidence the quirks this model is reported to exhibit have been positively solved.

Thanks

CVR is short for CVT-R which is the Coordinated Video Timings. Yes, used to reduce blanking.

 

M2T104 was never released as a downloadable file. You can only get it if you purchase the U2518D new directly from Dell. We have no idea what revision resellers may have in stock. The changes/fixes from M2T103 to M2T104 were not released to us.

Re: U2518D, M2T104 firmware fixes, CVR timing?

If I had to speculate the root cause of the anomaly with the u2518d, the symptoms suggest the accrual of slight delay until there is not ample time for blanking to occur and an incoming frame essentially overwrites the preceding frame. To have employed reduced blanking suggest the u2518d could be pushing the envelope of doing 1440p. With HDMI 2.0, presumably soft HDR (versus hardware accelerated), and CVR timing, the u2518d poses a challenge that processing time be absolutely consistent per frame or there will likely be a hiccup when frame processing time accrues some slippage. Have to wonder if the experts have looked at the glitch from a variance in frame processing time.
