I'm running ATi Mobility Radeon HD 4650 with 1 GB DDR3 memory and Dell U2715H monitor connected by HDMI. I managed to get it's native, 2560x1440 resolution with CRU, but only at 40 Hz refresh rate.

You written in the first post that "HDMI limits depend on the graphics card. AMD 7000-series and newer cards support up to 297 MHz. Older cards are limited to 165 MHz unless the driver is patched.", so I used your AMD/ATI Pixel Clock Patcher and it says that all limits are patched (besides Low-resoluion limit, which is "found"). I also edited Extenstion Block (HDMI support) and checked "Override maximum TMDS clock: 340 MHz".

But still I can't get any higher refresh rate - any pixel clock values over 165 MHz are not working.

HDMI cable that I'm using, on the other laptop with Intel HD 5500 Graphics runs fine with this resolution at 60 Hz.

Is there any way to get higher refresh rate on my config, or I should buy one of the "DisplayPort to HDMI active adapters" to get it working?

Thank you in advance for your time!

The patcher is for 5000-series and newer GPUs. There's no way to make HDMI go over 165 MHz with a 4000-series GPU. If you have DisplayPort, an active adapter might work. I don't know what limitations 4000-series GPUs have with DisplayPort since most cards didn't have DisplayPort back then.

Many thanks for reply!
