I am not a gamer but an independent software developer. I need to test how my software (that runs in windowed mode and does not modify graphics settings) works under Windows at high screen resolutions. I cannot use a VM for this, sadly.
My device is Lenovo IdeaPad Flex 5 16ARB8 (82XY0054CK) with 16 GB RAM, AMD Ryzen 5 7530U with integrated AMD Radeon Graphics and 512MB VRAM (1333MHz LPDDR4).
I have tested the internal display and both HDMI TVs in my house, with the following results:
| Screen | Native resolution | VSR limit |
| Built-in | 1920x1200 | 3840x2400 (2x) |
| Old LCD TV | 1360x768 | 2560x1440 (1.9x) |
| New LCD TV | 1920x1080 | 3840x2160 (2x) |
| 4k screen I might buy | 3840x2160 | ??? (Please tell me) |
So it appears that the limit of VSR on my card is double the native resolution of the monitor, with the added limitation that it needs to be a somewhat standard resolution (which 2720x1536 is not so 2560x1440 is the limit for a 1360x768 panel). However, there must be another limit: pixels are stored in VRAM so resolutions beyond a certain number of pixels cannot work. What is the limit for my setup, and how high could I push VSR on a 4k screen if I had one? I don't want to buy a 4k monitor or wait for a 4k HDMI dummy to arrive from China just to find out that I cannot push beyond 4k. I really don't need to actually see 4k, I just want to know how large I can get the window of my program with this GPU.
