HTC EVO 4G's HDMI port is to blame for 30fps refresh rate cap

Many people will agree that the HTC EVO 4G is definitely one peppy handset, especially when it's packing an all too familiar 1GHz Snapdragon processor, but everyone knows that it can run even faster. Seeing that the HTC EVO 4G follows closely to other similar Android powered HTC smartphones, like the Desire or Droid Incredible, it made owners wonder why there was a 30fps refresh rate cap placed on the high-powered handset. During a recent HTC event, a representative for the company said that the problem can be found with the EVO 4G's HDMI port. Since it can only push out a frame rate of 30fps when the HDMI output is active, HTC decided to mandate it throughout the entire phone – even when it's not in use. With that in mind, the argument can be made for a software update that would allow the phone to detect whether or not the HDMI port is active – thus changing the frame rate accordingly.

I hope it's just as easy as a software fix, because honestly I don't understand what port type this is? Why didn't HTC just put a standard mini HDMI port; it's small enough and I can buy a cable at any local Radioshack, Bestbuy or Fry's.

mini hdmi is the worst idea i've ever heard. its not small enough and building a port for it to go into would be way too big. the hardware to make something like that isn't as simple as just making it the same exact size as the object that is going into it. oh and just so you know it is as easy as a software fix. i've rooted my phone and gotten 50 fps although it wasn't a legit fix. a lot of things weren't working since they needed more software info from htc.

I doubt i'll ever use the HDMI port on my EVO... i'd take 30fps video over a HDMI port any day. Its nice to have but i dont find it necessary. I'm crossing my fingers for an OTA update fix.

what do you mean you'd take 30 fps video over an hdmi port? it has a 30 fps screen cap, so if that's what you want you already have it.

I think 30fps is fine. Hell, films are shot in 25fps... Compared to old smartphones and even some mini cams, the smartphones are doing amazing at 30...

That's like saying I'm going to buy a car capable of getting 45 mpg, but because I've only had 10mpg before; I'm OK with the new one only getting 20 mpg. If the phone is capable of more then 30fps, why not make adjustments to insure it performs at maximum speed.

they are talking about the screen not the video capture. that is pretty sad that you can't read that. i've rooted my phone and gotten 50 fps with the cap off which is still pretty slow since most screens go at 60 fps.

Don't confuse frame rate with refresh rate. Realisticly the picture will only look as good as the worse of the two specs. A graphics accelerator running at 60 fps doesn't mean jack if the screen is a 50hz refresh rate lcd which is likely what our evo's have. Anything over the refresh rate is useless, not to mention human sight can't see beyond 60 arguably
