Hello everyone. I'm sorry if this isn't in the correct forum; I wasn't sure exactly where to put it.

I want to project the screen from my PC to two 55" TVs. I want them to be mirrored; showing the same image. My current setup is a Dell Optiplex 7020 PC with an IOGEAR HDMI splitter splitting the signal to two TVs. I have the two HDMI cables going from the splitter to the wall connectors, and then two more 15 foot HDMI cables going to the TVs. However, after running PowerPoints on this machine for a while, the TVs start to flicker, and cut in and out. It seems to me as though the signal is not strong enough to power both these TVs. What kind of hardware do I need to make my PC display to both of them at the same time?

Thank you!
Alan

Unfortunately, it only has two HDMI ports, but when I plug them each into their own HDMI port, the problem is worse.

Do you have a dedicated graphics card or are you using the internal graphics processor that is on the CPU?
If you are using a dedicated gpu, make sure all of your drivers are up to date. If that doesnt work its time to get a new gpu
If you are using the HD Graphics thats built into the cpu, make sure the drivers are up to date. If that doesnt work, its time for a dedicated gpu.

If updating drivers doesnt work, I recommend this gpu
https://www.amazon.com/MSI-Profile-PCI-Express-R6450-MD1GD3-LP/dp/B004X6ABTM/ref=sr_1_1?ie=UTF8&qid=1467045314&sr=8-1&keywords=low+profile+graphics+card

It comes with a low profile bracket so it will fit into your small form factor PC.
But to have two hdmi displays, you will need to grab an adapter for the second display as this GPU only has one HDMI port.
You can find a cheap DVI to HDMI adapter on Amazon for less than $10.

It is a powered splitter. What I was thinking of was getting a powered extender to place right before the TV, because I have about 30ft of cable. Would this be a good idea seeing as I already have a powered splitter?

Thanks!

It can display to one TV fine. It's when I try to display to both TVs. I originally had this problem when I didn't have the splitter, where I was just using the two HDMI ports on the graphics card. Then I introduced the splitter to it and it helped a little bit, but the TVs still cut out at times.

Right now I have two 15 footers connected by a wall plate. Do you think it'd be better to just have one cable instead of two?

You have an HDMI wall plate? well how long is the cable in that? it could very well go over the limit.
