However, he also stated that they have reports of the FPS rate causing sluggish screen responses (which in all honesty, it doesn't) but they haven't been able to replicate....He did't address as to whether or not any changes would be made or not.."

One commenter reports that in their reply from Sprint they were told that they mention the fps cap in the owners manual (though I haven't found it).

Given these responses, it's a lost cause.
That said, the HDMI port on the EVO isn't necessarily a slapped-on afterthought. Per the geniuses and magicians at XDA, it's a Silicon Image Sil9022a:

You might find NeoteriX's results interesting:

What makes our 720p recording inferior (imo) to the iphone, nokia n8, and samsung galaxy?

As well as this follow-up in the same thread:

NeoteriX

I forgot to post the link to my documentation of this as well: Video Demo: HTC Evo playback of HD/720p movies over HDMI out

It took several takes to get that video, and the Evo was playing HD content back all the meanwhile.
Also in that thread, a few of us were speculating that the 65 nm process technology would consume higher power and produce more heat. Close, no cigar - but very close.

Again, per XDA, there are several issues with the EVO's HDMI - for one, there's no sensing for an external device - or even a user-accessible on/off switch for it. That baby is always powered up, unlike the Droid X, if I read that correctly.

If true, then yeah, HTC has frequency-limited the chip for power and heat management.

So, yeah - the issue is really about power management, as we all suspected, and a big tip of the topper to the few, the proud, the XDA that seem to have proven that.

It all comes down to use cases. I'd be pretty happy with _most_ 720p _video_ at a steady 30 fps - despite 60 being an ATSC-supported mode.

Remember - Blu-ray players are at 24 Hz, matching 24 fps film source.

That's the justification HTC's using - if you notice, 29.97 fps is the NTSC standard.

I'm not ready to disbelieve a fix is inevitable. All we can do is stay tuned in for the latest results.

~~~~~~~~Just some stuff that might be interesting:

The unveiling -



I also found NeoteriX's choice of test material quite interesting. You may have followed Buck from the beginning and already know the backstory, but if not -

Big Buck Bunny - Wikipedia, the free encyclopedia

That particular vid is at 24 fps.
