Nvidia DSR and DLDSR tech can work on some DSC monitors

Posted on

If you own a Nvidia GPU, there’s a chance you are using Nvidia Dynamic Super Resolution (DSR) or Deep Learning Dynamic Super Resolution (DLDSR) to run lighter and older titles beyond native resolution to squeeze as much image quality out of your setup as possible. In the past, these two technologies were only known to work on monitors that don’t use Display Stream Compression (DSC). Still, according to TFTCentral, Nvidia’s two downscaling features can work on DSC-enabled monitors if you use a single cable to connect your monitor to your GPU.

To be clear, Nvidia’s support page for DSR and DLDSR states that neither of these technologies is supported at all while using a monitor with Display Stream Compression (DSC) enabled. The only display configurations Nvidia says are compatible with DSR/DLDSR are standard monitors without DSC (that are plugged into a desktop system), discrete GPU notebooks without Optimus GPU switching, and notebooks with Advanced Optimus technology — in other words, laptops with a MUX switch.

However, TFTcentral found that many of its readers could enable DSR or DLDSR on DSC monitors despite what Nvidia specifies on its DSR/DLDSR support page. TFTcentral reached out to Nvidia for comment, and Nvidia responded with a detailed response explaining what was happening.

“NVIDIA DSR, NVIDIA DLDSR, and NVIDIA Image Scaling are supported when DSC mode is enabled if the pixel rate needed to drive the display mode does not exceed the GPU’s single head limit. If GPU uses two or more internal heads to drive the display, NVIDIA DSR, NVIDIA DLDSR, and NVIDIA Image Scaling are not supported,” a Nvidia representative told TFTCentral.
