zorkiii Posted February 7, 2018 Share Posted February 7, 2018 Just wanted to share a scenario I ran into and what fixed it, in case it helps anyone else. I bought a new Samsung TV over the weekend and hooked up my PC running Launchbox via HDMI, and everything was working fine. I launched into my Windows games folder and played some, everything was working great. Then I launched a few games from other emulators that use Retroarch and everything was performing super slow and choppy, audio was stuttering at 1/2 speed. Since I had been playing other games without any issues, I initially thought there was something wrong with Retroarch so I installed a clean version, but this didn't fix anything. I then thought maybe I have some system issues and began uninstalling any recent software to check it again but no change. I also noticed this was happening with a few other emulators, but strangely not with Mame or Windows games and a few other emulators. Anyways to make a long story short, I wasted a few hours pulling out my hair and going backwards in config on several portions of the system only to find that the refresh rate on my PC had changed when connecting to the new TV...... I'm on Windows 10, I just right clicked on the desktop and went to Display Settings > Display Adapter Properties > Monitor tab, and noticed the refresh rate was set to 29 Hertz (?). Setting this to 60 Hertz resolved the problem. It must have been that my previous TV had this refresh rate? I'm really not sure honestly. Glad it's resolved, but feeling silly I didn't think of it *before* going down a rabbit hole that led me to screw up all my Retroarch settings. 5 Quote Link to comment Share on other sites More sharing options...
Charco Posted February 7, 2018 Share Posted February 7, 2018 I had the exact same issue some time ago when I connected my old laptop running RetroArch to my new Samsung tv also, glad you got it sorted 1 Quote Link to comment Share on other sites More sharing options...
Justin Whyte Posted August 27, 2018 Share Posted August 27, 2018 @zorkiii Thank you so much for sharing this! I had my entire gaming PC setup exactly how I wanted. I hooked it up to my Samsung TV, and experienced the same issue. After completely installing Windows, the issue still persists. I was about to lose it when I saw your post. 29hz. Same issue. Thank you for saving me from scrapping my system altogether! Quote Link to comment Share on other sites More sharing options...
BigSpoonyBard Posted March 1, 2019 Share Posted March 1, 2019 Just hooked up my computer to the TV for the first time after everything worked perfectly on its own and had the same problem. I was hoping someone else had already solved the problem, and there you were. Thank you! Quote Link to comment Share on other sites More sharing options...

stevebor1 Posted September 19, 2019 Share Posted September 19, 2019 Thanks to this thread, I realized that my Lenovo m93p's integrated Intel 4600 can only output 30hz when running at 4K, which for me was causing the choppy audio as you mentioned above. Switching the resolution down to 2K~ and a min of 60hz refresh rate solved the issue. Thank you!! Quote Link to comment Share on other sites More sharing options...

Actually its possible its your motherboard or your connection/cable, that IGPU does do 4K60 but you need either a HDMI 2.0 port and cable, or display port. Standard HDMI ports and standard HDMI cables that are not 2.0 certified can often do 4K30, but they dont have the bandwidth for 4K60. If i was you i would look into it, it could be that your motherboard supports 4K60, but you simply have a non spec HDMI cable without the needed bandwidth to transmit 4K60. https://ark.intel.com/content/www/us/en/ark/products/80806/intel-core-i7-4790-processor-8m-cache-up-to-4-00-ghz.html Quote Link to comment Share on other sites More sharing options...

I forget that 3840 x 2160 is actually 4K btw, I have a Intel i5, 4570T with DisplayPort 1.2 to HDMI which can push the 3840 x 2160 @ 60hz to the TV just fine. 1 Quote Link to comment Share on other sites More sharing options...

How do I know if the HDMI cable can handle it? know the GPU and MB can Quote Link to comment Share on other sites More sharing options...
UncleBubba Posted May 9, 2020 Share Posted May 9, 2020 Greetings from the dystopian future year of 2020. I've been troubleshooting this problem for hours, and I can't believe the answer was this simple. Thank you. Now that this is solved, I'm going to go weld a cowcatcher to the front of my Honda so I can battle others for a roll of Charmin. 1 Quote Link to comment Share on other sites More sharing options...
Darren Wilson Posted October 21, 2020 Share Posted October 21, 2020 I've changed my settings and I'm still getting issues on my Samsung Q90t. Any other suggestions, you fine people? Many thanks, Daz Quote Link to comment Share on other sites More sharing options...

Fire_Blast07 Posted January 21, 2022 Share Posted January 21, 2022 Actually i'm having the same issue, except the refresh rate for me is set to 144,000 hz. Changing it to 60,000 hz didn't work either. I heard people saying older version don't have these issues so i'm gonna try that later but this is still pretty frustrating.

Hansnld Posted February 4, 2022 Share Posted February 4, 2022 Thank you so much! I had this problem for a few minutes, did read some solutions that did not work or did not make sense. I tried your solution and it worked perfectly! Likewise, I am sure I would spend countless hours with reinstalling etc etc! This did save me a lot of time! Thanx a million!
