I have an issue i cannot resolve so i am trying to find a new graphics card.
I build pc's but i haven’t built a new one in a good while. I would like to build a whole new pc but that is out of my budget currently as i got a new tv a samsung un50ku6300. It is a 4k tv. The reason i need a new graphics card. Whatever graphics card i get now will most likely go into my new pc when i build a new one. I most likely will run the tv at 1080p instead of 4k as i imagine everything will be very tiny at that resolution. The new graphics card needs to be at least as powerful as my old one without breaking the bank. Would like one supported good on linux with official drivers. I am tired of relying on open source drivers as there is no support for my card anymore. I would also like but not as important the latest hardware support for playing video so cpu dont have to do all the work.
My current system is an TA790GX A2+ motherboard amd 945 phenom II quad core cpu @ 3ghz. xfx ati radeon hd 4850 1gb card. It has 2 pci express x16 2.0 ports, 8gb of Gskill DDR2 800 pc6400 memory.
Very long explanation below of why i want a new graphics card with hdmi instead of dvi.
Explanation of my issue. On my tv when i output dvi to hdmi the tv goes out of range at the grub boot menu onward and it makes my main 1920x1080 pc monitor H213H go wonky with nearly unreadable text as it tries to output 4k to the tv and my graphics card cannot support it so i get no display on the tv and it isn't auto scaling to 1080p. Probably a linux bug. The resolution is still set correct on the monitor when that happens oddly. After i manage to get into my operating system i can change the resolution on the tv and everything is back to normal on both displays. I can fix this by going into service menu on my tv and changing an option to write EDID information for hdmi 1.2 on the hdmi port the pc is using. It only works on port 2 and 3. I don't want to be mucking around in service menu so i changed it back to off. I don't want to mess up my hdmi ports and not get 4k to work at a later date on my hdmi like if i get a 4k blueray player. Interestingly if i hook up my other computer with hdmi and onboard ati video it works and sets correct resolution using the same os.
Even if i fix the video through the service menu of my tv or after i boot which is what i am currently doing i have another issue i can't make go away. The audio will stutter on the tv every 10 seconds like bad audio / video sinc. Like a skip here and there. On the computer with hdmi there is no issue on audio stutter. If i use the same adapter in windows i get no audio but it sets the correct resolution every time. The reason i think that is, is because i don't have the ati brand adapter but a generic i found at the store and catalyst looks for a special chip inside it that only the ati brand adapters have. Another note if i output audio through headphones hooked to the pc when on linux then the sound is fine but what i noticed is if i have it playing on my monitor everything looks normal. If i move screen to tv instead and still using headphones plugged into the pc i notice that it don't look right like maybe video is ahead or behind the audio on the tv and that may be what causes the stutter as the tv wants to keep sinc when using hdmi. I noticed the hz on my monitor is oddly set to 59.9 and on the tv 60. Although my monitor specs say it supposed to be 60. I think it can run either and linux wont let me select 60 to see if that fixes it. The stutter happens if mirrored or not also. The stutter does not happen if i hook that adapter and hdmi cable up to my monitor. Monitor will play the sound flawless. It only stutters if that adapter and cable is hooked to the tv and i am outputting audio to the tv via dvi to hdmi adapter. I once fixed it by unplugging cable with pc on from tv and plugging into monitor and back again to tv or something odd like that. Not sure what did it.
