poor resolution on chrome tab

anybody experiencing poor resolution quality while casting your chrome tab? I know my connection is not the problem because I have 54mpbs fiber optics...

Got to your chromecast extensions options and change the tab projection quality

yes already tried that and still same problem

I have the same problem. Any time I cast a tab I lose lots of video quality. When I cast the entire screen it looks much better but that won't allow audio streaming right now.

Netflix and youtube quality is great but chrome tab must still be in beta

<AOL>Me too</AOL>
Seeing the same thing. Casting the whole screen to my 1080p screen looks great. Casting a tab looks like someone miscoded an antialiasing routine.

Tab casting has nothing to do with your Internet speed, and everything to do with your internal network speed and PC power.
Your PC is rendering the page and streaming to the Chromecast. My HP Ultrabook can barely handle 3 frames per second using wifi, but my desktop does a good job at full 720p video hardwired to the router.

Terrible Tab stream quality

I just got my Chromecast and the Netflix/Youtube playback works awesome and I have no issues with HD, but when I stream a tab from Chrome on my Macbook Air it looks very bad. It looks the same no matter what setting I've tried and seems like there is glitching graphically, not just poor resolution. I even moved it from my TV to a desktop monitor that is close to my router and it does the same thing. Has anyone ran into this issue?
EDIT: Tried streaming a tab from my Windows desktop and it looks fine, so it appears to be isolated to my Mac.

It could be your MacBook not the chromecast.. I can share my whole screen and watch movies through chromecast without a hitch.
It diesnt sound like your WiFi is bad so it has to be your laptop

I tried installing the Chrome beta release and it works fine now on my Macbook. I was just worried that it might somehow be defective, though I thought that would be pretty unlikely since Netflix streams perfectly. I'm not sure why I would have issues with the stable release of Chrome, but it looks perfect streaming 720p tabs on the Beta release now.

Also while tabcasting I have noticed reducing the resolution does not impact much in image quality. I hardly see a difference. But it does reduce the stream quality. You/ anyone else having issues can try reducing the resolution to 480p using the gear icon while tabcasting. Ignore this if you are a videophile
Edit: nevermind the above. I actually did not see the attached image that is horrible quality. I did not had this bad of an issue. One more thing I have noticed is that it is better to have your laptop, connected to power, as sometimes on battery, the laptop OS power management may try to reduce wifi performance to save battery.

Do you have a 2013 MacBook Air? I had the same problem with mine but fixed the issue by changing a setting in Chrome:
Chrome browser -> Settings -> Show advanced settings... -> In "System" uncheck "Use hardware acceleration when available".

Had the same issue and this ^^ fixed it.

same here. stopped the stuttering too!

I have had this issue as well using Samsung Chromebook I an stating to think it has to do with my processor.

I have the same problem, with a high end laptop.

Turning off hardware acceleration worked on my 3yr old basic computer. Going to try my Asus smart tab tonight, hoping for the same results

I'm having the same problem streaming video from within tabs. I'm using a Dell Laptop circa 2007 though. I don't use it for anything else and it's been gathering dust so I was a bit excited that I might be able to tab stream from it and maybe use it for ESPN, AMC, or HBO.
Turning off hardware acceleration did help, but I get stuttering and the audio isn't synced with the video. Switching to 480p didn't make much of a difference. I've updated all the drivers, but it's running Windows 7 and the drivers were made for XP.
I'm hoping a chromecast update may clear this up.

I'm convinced it is more a Chrome issue than Chromecast. I can stream 1080p video just fine if it is local. The quality stays, there is no stuttering, and audio is synced. It is only when I do online content that the issues show up.

Here's a link to the minumum system requirements for streaming.
https://support.google.com/chromecast/answer/3209990?hl=en
In my case, I'm running a t2300 core duo processor at 1.66 GHz. Graphics is an ATI Radion Mobility X1300. It looks like it's subpar at best based on the requirements.

I'm running a 1st gen i7 965 @ 3.2 GHz and 2 GTX 280's in SLI plus 12 GB of RAM with a Belkin N900 router and 105/20 Mbps connection and with my TV sitting less than 10 feet away the quality sucks!

I don't get terrible tab casting quality, but there's no doubt that the video isn't perfectly smooth. It stutters, skipping a few frames about once per second, which is pretty distracting. I'm kind of puzzled as to why.
The video plays smoothly in Chrome on the desktop system I'm casting from, whether it's an internet stream or a local MP4 file, so it's not a source problem.
I have a pretty fast desktop system doing the casting (Intel Core i5-3770K overclocked), and it never shows more than 14% CPU usage and plenty of free physical memory while casting. Switching resolutions between 480, 720, and 720 Extreme in the casting options makes a small difference to the CPU load (range 8% to 17%), but no difference at all to the stuttering video that I can see.
I think I get a pretty good connection to my WiFi-N router from the TV+Chromecast location. A laptop in the same location shows connected at 130 Mbps with Excellent signal strength. I can force a wide channel for even more speed, but it doesn't make any difference that I can see. Certainly normal internet video HD streams seem to be perfectly smooth when coming direct from Youtube or Netflix over WiFi, never a stumble. You would think that if WiFi bandwidth were the problem, switching from 720 to 480 would make a difference, but it doesn't.
So what's the problem here? Is it just a quick and dirty beta implementation by Google that doesn't do a very good job? Is there some hidden bottleneck? Is it impossible to re-encode video with high efficiency for casting on a typical system? (but in that case why are they using an algorithm that uses only a small percentage of one CPU core?)
I've tried some of the suggested tricks, like turning off hardware acceleration in Chrome, which increases CPU usage a bit, but makes not much if any apparent difference in smoothness of video. I've also tried disabling real-time anti-virus checking, but it's hard to tell if it's any better.
I not sure if there are any other Chromecast owners who actually get smooth video tab casting performance or not. People who say it's fine for them may not have looked very closely, and maybe wouldn't notice video stuttering unless it was pointed out to them.

There's more to it than CPU bandwidth but I can't say what.
I can say that I am well aware of what stuttering and frame loss looks like and I get little to none on a MacBook Pro that doesn't meet Google's requirements for tab casting.
I guess my point is that it's still in beta and we all can hope for better.
Have you tried using Plex?

I don't see how using Plex would make any difference. Plex doesn't have native Chromecast support, so I'd still be casting a tab.

Well whatever the problem is at least it only cost $35 because I would be really pissed if I paid more for it in its current state.

I went out and bought a n n150 usb wifi adapter for my desktop. It's an I5-33570k processor overclocked to 4.5GHz, 8 Gb of ram, and a GTX570 graphics card. I'm getting much better reslts from this than my circa 2007 dell laptop.. Video is definitely watchable and quality is generally SD or better. There is some very slight frame loss, which is noticable. The wifi signal is --60dbm where the chromecast is.
I still need to play around with some settings. I have the chromecast set to 720p, but not extreme bandwidth. For some reason unchecking hardware accelerationleads to videos not taking up the entire tab.

I have almost the same desktop system configuration as you Wrngway, and I get the same results: reasonable tab-casting performance with low CPU utilization, but still getting some very noticeable dropped frames.
I also tried my 2009-vintage Core-2 Duo laptop (P8400 CPU at 2.27 GHz). No good - 100% CPU utilization, the video stutters on the laptop screen and on the Chromecast it's just jerky frames and then it freezes after a few seconds. Dropping the res to 480p improves things slightly, but still not watchable.
Actually I have a new theory about what's wrong with tab casting that causes it to skip frames and stutter even though it's running at low CPU utilization. The problem is that it isn't buffering enough. When you compare the Chromecast TV output to the computer screen, it's obvious that there's less than 1/2 sec. lag. When the picture content changes rapidly in the incoming video stream, there's a spike in decoding/encoding performance requirement that momentarily exceeds real-time CPU capacity, causing frames to be dropped. An instant later it catches up when the performance requirement drops. The CPU utilization is relatively low on average, but there's still not enough CPU power to handle the peaks. The solution would be more buffering and less aggressive frame dropping. There's actually a buffer length setting in the hidden Chrome extension settings, but it doesn't appear to have any effect. In any case, the encoding algorithm would have be smartened up to not drop frames as long as there's plenty of buffer time to catch up.

Hulu+ - Low quality streaming

Hello everyone!
I just recently got myself a Chromecast to use specifically with Netflix and Hulu Plus (casting from an iOS device).
Thanks to this forum I knew how to proceed for everything beforehand, using Smart DNS in my router, blacklisting google's DNS servers, etc. I have a TP-Link router.
Netflix is working perfectly, bumps to the 720p stream in about 6 seconds and another 5-6 seconds later it streams at 1080p without any noticeable drops so far.
Hulu Plus however is being problematic. It might smart in HD (sometimes) but either a few minutes later or after the commercials it drops to SD quality and rarely ramps up again. Starting the stream again helps, but only for a short while.
As I currently don't have another H+ device to test, i was wondering if the hulu plus implementation with Chromecast is indeed flawed or if this is happening just to myself (I understand that being overseas might not help - although I'm not sure which CDN I'm getting the content from), but it's really annoying seeing all the godawful pixels on my screen constantly - the Ads... pfft, well, those are always in 720p, go figure!
Anyway, hopefully you'll be able to share your experiences with me!
Cheers, thanks.

[INFO] Chromecast Cast Screen Mirroring Lag Test

As promised in another thread, I captured a video of the native full-screen mirroring lag.
Delay is half a second or less, video seems shows closer to quarter of second. Content doesn't seem to matter much - feels like the same delay mirroring streaming TV.
Sorry, the darn rolling shutter makes it pretty much impossible to discern the hundredths of a second, tenths are barely legible...
And please ignore the audio - my wife was wondering what I was doing... as usual. :angel:

Have you tried to stream a movie or channel like from xbmc? I have a Sprint Galaxy s3 and the same router also. I have used VLC player with my movies. I have a network with 30/3 speeds.

To add more my problem is while I'm on xbmc playing a channel it will buffer and lose sound then the soundtrack will be off from video like about 5 to 10 seconds.

I don't use XBMC but I've played TV episodes from Xfinity TV Go (which doesn't support Chromecast) and haven't noticed any problems.
Since the screen mirroring traffic is also going through WiFi along with your streaming it'll take up more WiFi bandwidth so signal reception on all devices involved becomes more critical.
I tried the same with AllShare Cast (I have an AllShare Wireless Hub connected to another input on the same TV) and while yet lag is similar, I noticed that WiFi Direct seemed to limit general network traffic more. My streaming playback video would break up from time to time. No such problem with Chromecast mirroring.

my chromecast was eating dust for 1 month because my g2 have so much lag over screencast that it takes 10 sec just to navigate. pictures and videos were like crazy late.
now i bought nexus 7 and man even the videos on my device runs smooth...
whats the issue with g2?? tried both stock, custom, g3 port and aosp.

laptop lag
Having this lag issue using cast entire screen even just on the desktop moving the mouse works fine using an s4 & g3 anyone have a fix yet?

[TROUBLESHOOTING] Poor video? Check your Chromecast throughput with Netflix

If you have Netflix, this is a way to check your Chromecast's throughput.
Unlike a simple Internet speed test (which tests the throughput from some Internet server to your router), this test helps diagnose Chromecast's throughput, which is limited by its WiFi signal reception.
Play this video:
http://www.netflix.com/WiMovie/70136810
You should start the video fresh when changing conditions - resuming from pause doesn't always seem to increase the rate.
Throughput Diagnostics:
The bitrate and resolution will gradually rise during playback.
Under ideal conditions (excellent WiFi signal and adequate Internet bandwidth) you should be getting a bitrate of 5800 at 1920x1080 resolution on Chromecast.
Oddly enough, my desktop computer gets bitrate 3000 at 1280x720 resolution on a powerline connection. I'm not sure why it's limited, it should be able to do higher bitrate and 1080p. YouTube seems to prefer 720p over 1080p on this machine as well, so might have something to do with ping times or something. *shrug*
If the video buffers or the bitrate remains consistently low on Chromecast and you know it's not your Internet speed holding things back, then your Chromecast's throughput is being limited by your WiFi. Probably Chromecast has poor reception - try the HDMI extender and/or repositioning or reorienting your router.
TV/Sound diagnostics:
From the 8:40 mark there are good test patterns to help diagnose aspect ratio and overscan issues that you might be having with your TV too.
The large white circle should be circular (tilt your head to check)
On the grid with circles should, the corner circles should touch the edges of the screen but not be cut off. If they're cut off, your TV is performing Overscan or is not in 1:1 pixel mode (if it's a 1080p TV).
The subtitles also seem to imply there are some subtitle font/color changes and multichannel audio tests, but I only have 2.1 sound so I can't tell, and all my subtitles are fixed-size and yellow (probably the Netflix Chromecast app doesn't support the different subtitle formats yet).

I think because you were using chrome browser to streaming this content.
Because of security reason, the limitation of bitrate is set to 3000. if you are using safari you could reach 5800.
